Title: Another double build: Sopwith Pup (HR Models) and Triplane (Revell), 1:72
Post by: IanB on March 30, 2017, 10:31:10 AM
This is more of a notice of intention at the moment, as I want to finish the Muromets before getting involved in anything else.
  I have decided on my next build, and as I have also decided to repaint the roundals on the Muromets, I want something to do while waiting for the previous colour to dry enough to be masked. A little reasearch and parts clean up fits the bill, so here is what I'm starting with.

The HR Models Pup is a really nice kit. The detail is well moulded and crisp. The decals let it down a little as the blue is far too light, but that's easily remedied. So here are the standard sprue shots.....

 I think most 1:72 scale modellers are familiar with Revell's Triplane. My kit has new decals which are very nicely done, but the kit does need some work.....

(https://c1.staticflickr.com/3/2861/33687460776_03ec7beca9_b.jpg)

 The fuselage will be reskinned on the cockpit sides and on the rear decking to give a better rendition of the ribbing under the fabric. I will be using an Aeroclub engine (if it fits!), prop and Vickers gun, and either my own 3d printed wheels or the spare set from the Pup kit, I haven't looked closely at them yet to see if they will work. The cowling will also need some work to open up the vents and add a little more depth to it, and the struts may be modified and used, or scratchbuilt...again I need to look a little closer at what I have. The tail surfaces will probably be scratchbuilt, the undercarriage definitely will be! And then there are the ejector pin marks....

See you soon!

Ian

It's been out for a while now, Steve, but they sold out very quickly! I think Hannants still has a couple of versions in stock, but there were a few more options available that are hard to find - the Aces boxing was one, a Japanese one, and an RNAS one which I have.

Looks like another very interesting double from your bench. I'll follow that closely. Me too, I never heard before of the HR injected Pup. It looks very nice and as if the old Airfix Pup has its predecessor.

Thanks for the interest everyone! I did the last of the painting on the Muromets national insignia this afternoon so that left me to start looking at the Triplane a little more closely....

After cleaning up the flash, the first thing I noticed was that there was very pronounced rib detail on the UNDERSIDE of the wings! So that was the first job - to remove it all!

Here's one of the centre wings done, and the second one waiting for attention.........

(https://c1.staticflickr.com/3/2894/32934328713_ea01c5464d_b.jpg)

 There were also a lot of sink marks/ejector pin marks on the wings, so these were then either sanded off or filled accordingly.

 I then looked at the fuselage, and the first thing I noticed was the cockpit.

(https://c1.staticflickr.com/4/3834/33706839226_31a8124d46_b.jpg)

The front was too far back by about 3mm and the rear by about 1mm. I marked out where the front should be and filed/sanded it out..

(https://c1.staticflickr.com/3/2926/33706846056_61f40b3514_b.jpg)

It's difficult to get the correct perspective on both the front and rear with my camera, but this is close.

(https://c1.staticflickr.com/4/3942/32934330193_ba39e3be8a_b.jpg)

So after a few hours fiddling about today, this is what I achieved:

(https://c1.staticflickr.com/3/2904/33747502365_2d60dc17b6_b.jpg)

 A fair improvement to be getting on with, more to come soon!

I got a little carried away on the Triplane today, after sorting out the Muromets roundels!

First I looked at the struts - I removed the lumps on the sides for locating the wings, and sanded them to a more aerodynamic shape (more aerodynamic than the plank shape they were moulded in at least!). I then added a piece of .015"x.030" strip to the edges of the middle wings, as the struts should pass through the wing, not butt up against it.

(https://c1.staticflickr.com/4/3933/33764891025_4c0e0545ca_b.jpg)

The remainder of the gap will be filled with PPP once the wings are mounted on the struts. I may even do that before mounting the wings, we'll see.... The cut outs at the rear of the middle wings were also enlarged by sanding them out to the second rib. The kit, for some reason, has the cutouts end somewhere between the first and second ribs!

 My thoughts then turned to the interior, and since I want to add a reasonable amount of detail, I wanted to make sure I could do that without any problems from the lower wing. I therefore taped the fuselage together, then taped the lower wing in place to see how much, if any, of the wing edges might need to be removed to ensure that the cockpit framing would not stop me adding the wing later! I stuck a pencil in through the cockpit and marked the inner wing edges so that I could sand them off to be level with the fuselage sides..

(https://c1.staticflickr.com/3/2852/33723363516_52ccb07ece_b.jpg)

Not too bad, but a little sanding needed!
 Once that was taken care of I added the basic framework with .020"x.020" rod and measured up for the false floor using dividers. This will hide the edges of the lower wing fitment and enable the cockpit to be built in situ before closing up the fuselage. The framework so far is just top and bottom longerons, and the 3 vertical formers each side in the cockpit area, care being taken of course to ensure that both sides matched!

(https://c1.staticflickr.com/3/2822/33635228441_8868270eb1_b.jpg)

The floor was then cut from .010" sheet and glued in place....

(https://c1.staticflickr.com/4/3849/33723362266_387dddd4e1_b.jpg)

(https://c1.staticflickr.com/3/2852/33764511755_207f7c73cc_b.jpg)

A perfect fit!

 The formers were then added on the floor to match the side ones, and the cockpit sidewall framework was added using .010" rod for the longitudinal ones, and .010"x.030" strip for the vertical ones. I added the horizontal ones first, then when dry, I used a scalpel blade to cut slots for the vertical formers to fit into. This worked fine on one side, but on the side I'd added the floor it was virtually impossible. If you use this method, do the sidewalls before adding the floor!

(https://c1.staticflickr.com/4/3696/33723359526_5382e11b59_b.jpg)

 I haven't added the foremost vertical former as it won't be visible, and I'd had enough by then anyway!

Post by: IanB on April 02, 2017, 05:32:38 AM
Thanks to Rick, Steve, and Marc for the comments. The Revell kit is a reasonable representation, but as you say Marc, it needs a lot of work to really make it accurate - it's a good starting point though!

 I reached the point yesterday where I was ready to spray the interior of the Triplane, so today I dug out the Pup and sprayed them both together.

(https://c1.staticflickr.com/4/3951/33737472266_d944b268a9_b.jpg)

Ready for a start on painting the wood frames now, then I will be able to add the lower part of the struts on the Triplane, and the rest of the interior detail on both of them.

 Since the Pup was now out of its box, i clipped all the main parts off and did a dry run to see how everything fitted together It's really not bad at all, especially for a short run kit! There are a couple of small areas which need attention though....

The fit of the lower wing is a little tight, so I had to carefully file out the gap between the wings to get them to fit over the fuselage, and also square off the rear part of the opening in the fuselage.

(https://c1.staticflickr.com/3/2833/33393770700_867bd60efe_b.jpg)

Note too, that the front part of the wing is the lower drip channel under the engine, and this part fits between the fuselage sides, so the bottom edge of the firewall needs to be filed to give a nice square,close, fit.

(https://c1.staticflickr.com/3/2879/33649197991_b05e26c9f8_b.jpg)

 The other part that needed a little attention was the upper front fuselage panel. Two are provided in the kit, one for an armed, and one for an unarmed, version. Place this part on a flat sanding stick and gently sand the mating surfaces to give a flush fit on top of the fuselage halves - particularly at the rear end, where it meets the front of the cockpit.

 This is what I ended up with after that little session..

(https://c1.staticflickr.com/3/2934/33649201241_8cbdbaf535_b.jpg)

(https://c1.staticflickr.com/3/2928/33649195801_e074c76aa6_b.jpg)

 There are also 3 cowlings in the kit: Sopwith, Standard, and Whitehead, along with 2 sets of wheels, one showing the spoke pattern through the fabric, and one not, so even if you can't find the specific kit you want to build the version you desire, you should be able to build it from any kit and just source decals from elsewhere.

 The wing tips need a little attention and reshaping, but nothing major. They are also a fraction too long, but I'm not going to bother with that.

 Back to the painting!

Thanks Stephen, I need a little change of focus during a big build, to stop it getting monotonous, so this is serving that purpose! The plan is to finish the interiors, button them up and then get back to the Muromets.

 A fair bit of progress has been made to that end, especially on the Triplane. The interior paintwork is done, and I made up the seat supports and foot boards, painted, and added those. The seats for both are Barracuda resin, with Eduard PE belts. I have also made an instrument panel, easily done as it's almost identical in size to the one in the Pup kit, and the small wooden panels behind the cockpits on both.

(https://c1.staticflickr.com/3/2816/33695707011_c0bfd9b27f_b.jpg)

and the Pup....

(https://c1.staticflickr.com/4/3857/33784055916_3553d48079_b.jpg)

 Tomorrow I hope to get the controls in and then I can button them up!

Thanks for looking in!

 Yes, they are. They do 2 different sets of seats, this style and one with the open back and lacing. They also do Albatros wheels in 1:72. I use them a lot, they are very well moulded!

 Thanks Steve!

 I did take some pics of the interior after fitting the control column and rudder pedals, but my phone seems to have eaten them....not the first time pics have disappeared! Anyway, the fuselages are now closed up!

(https://c1.staticflickr.com/3/2810/33032889983_d4823ae09c_b.jpg)

(https://c1.staticflickr.com/4/3847/33032887493_c135d5e996_b.jpg)

 The Triplane cockpit opening was then adjusted by carefully adding a little Mr Dissolved Putty around the rear edge with a small brush, to bring it forward, and the rest of the leather combing was added in the same way.

(https://c1.staticflickr.com/3/2840/33805599406_edfb4fc0a6_b.jpg)

 The underside of the nose also needed some attention...this is as it comes, but the recess needs to extend to each side, so that was opened out with a file.

(https://c1.staticflickr.com/3/2815/33461893830_e29969052c_b.jpg)

 It is also a TERRIBLE fit, and will need some major fettling and filling to get it looking good...oh joy!

 Finally today, I looked at the cowling. It will need the vents drilled out, but my first job was to narrow the frontal opening as it is too wide. Opening a cowling up is not too bad, but narrowing it?

(https://c1.staticflickr.com/3/2933/33003185974_9508d1355f_b.jpg)

 I decided to cut a small circle with my circle cutter - here's a tip - rotate the cutter backwards! If you try to cut a small circle by rotating the blade in the correct direction, the blade pushes outwards and the radius is always too big! Do it backwards and scribe the circle rather than cutting it. (I won't say how long it took to figure that out....) Finally I managed to get a disc of around 10mm inner diameter and just under 1mm thick, which I placed into the cowling front, then glued with PlasticWeld.....

(https://c1.staticflickr.com/3/2910/33690482772_548bd9b0dd_b.jpg)

 1mm doesn't sound much, but it makes a huge difference! A little Mr Dissolved Putty and the next step will be marking and drilling the slots for cooling......

Thanks for looking in!

 Did I mention that the nose and under cowl was a bad fit?

(https://c1.staticflickr.com/4/3842/33861218555_f2f2503c1d_b.jpg)

 Not even close! So out with the .020" card. I added 2 pieces each side to level the bottom, then one more each side to reprofile the drip channel. I also added one of my rejects from yesterday's cowling work to clean up the firewall face....

(https://c1.staticflickr.com/4/3804/33476747160_d2a23f5186_b.jpg)

 Some PPP and sanding, and we have a much more acceptable front end...

(https://c1.staticflickr.com/3/2906/33731811411_bd090e9af1_b.jpg)

 Much better, I'm happy with that!

 I also tidied up the top of the cowling area which was pretty poor. More PPP to fill the sink marks and get rid of the slight dip which was visible in the profile view, and I think the nose is about right! Some minor details to take care of such as the carb air intakes and rescribing the access panels, but mostly done in that area now.

Post by: IanB on April 09, 2017, 11:27:32 AM
Thanks Steve, more to come, hopefully!

 The next step with the Triplane was to reskin the cockpit sides and turtle deck To do this, I stuck a piece of masking tape on the area I was working on and cut it to size. That was then stuck on a sheet of .005" card and cut out. The ribs/longerons were marked onto the back side with a ballpoint pen, with enough pressure to leave a mark on the outside face.

(https://c1.staticflickr.com/4/3938/33792104511_102dec09a6_b.jpg)

 It worked out ok for the Pup and the cockpit sides, but the rear decking on the Triplane was not the best....

(https://c1.staticflickr.com/4/3841/33764802512_db0276fe53_b.jpg)

(https://c1.staticflickr.com/4/3954/33792102641_524ca57c8d_b.jpg)

 I really wasn't happy with the Triplane decking so off it came. I then realised that the rear of the fuselage was too narrow, so added some pieces of .010" card to the sides to thicken it.

(https://c1.staticflickr.com/3/2906/33792100261_8bbf37e61b_b.jpg)

A little filler, some sanding, a little more filler, a little more sanding etc, etc, and the fuselage was thick enough and ready for reskinning..

(https://c1.staticflickr.com/3/2914/33764809772_a3e5b2bb38_b.jpg)

 Two more attempts were made at the rear decking before I was happy with it, and then I applied another coat of white to see what else might need attention....

(https://c1.staticflickr.com/4/3943/33764805382_d5df3fdbc6_b.jpg)

 There are still some small areas which need a little more filler and sanding, but I'm happy with the overall result, and after taking care of those tomorrow I can move on!

Thanks for looking in!

Thanks Alby!

 I have been distracted by the garden these last few days, getting to that time of year again, thankfully! However, I do now have the "wood" done on the cockpit decking For those looking for ideas on how to do it, here is how I do it for small areas such as these.

 First, a coat of CDL, or any other light beige colour... (I used Misterkit Acrylic RFC CDL)

(https://c1.staticflickr.com/3/2943/33596110480_8b207c43cb_b.jpg)

The second step involves the following: acrylic "leather", thinner, and a wide brush..

(https://c1.staticflickr.com/3/2833/33137589534_a724c71c93_b.jpg)

I dip the brush in the thinner, then the paint, and use a piece of scrap plastic to test it on to see that it's not too thin and covers as I want it If it's too thin it will pool on highlights and run around corners on props or struts leaving dark blobs....too thick and it won't be translucent enough to give the right effect - just a matter of practice (and it took me 3 efforts to get this acceptable on these!) The trick is to do very thin coats and add more if necessary, advice I often find hard to follow myself! Don't try to work the paint as you would oils, it will cause dark streaks and/or remove too much paint leaving dark streaks and bare patches. Just make one, even, pass of the brush from one end to the other.

(https://c1.staticflickr.com/3/2846/33851342701_1d0032f947_b.jpg)

 It's still a little darker than I would like but it's acceptable.

 Stage 3...

(https://c1.staticflickr.com/3/2831/33823667922_f77c15f049_b.jpg)

 Again, apply with thinner on the brush first and don't add too much...and you should end up with a reasonable (in 1:72) wood effect

(https://c1.staticflickr.com/3/2938/33596114210_9316628499_b.jpg)

(https://c1.staticflickr.com/4/3927/33137592644_0d2b17fb38_b.jpg)

 Once it's tidied up around the edges by the surrounding colours that should look ok.

 In other news, I have removed the ailerons (all 10 of them) and am preparing those for pinning and reattaching

Thanks for looking in!

Ian

PS does anyone know why some of my pics are now coming out bigger? They are all the same size on the other forum I post on, and the settings are the same for all of them. It only started doing this recently and I would like to stop it if I can!

Can't help with the pictures Ian but I can write that the wood effect looks very good. You are extremely patient to resin the turtle deck and add all of the other details - great modelling indeed.

Thanks Stephen!

 Just a little update this time around....I added .020" x .040" strip where needed on the ailerons to reshape them after removal from the wings. The Pup ones didn't need any correcting, but because of the moulded gaps on the Triplane, I had to add strip to regain the correct dimensions.

 I have also opened up the rear fuselages on both, and added .016" brass rod for the stern posts....

Beautiful work Ian on a scale that I'm no longer building due to the fact you've got to be good and you most certainly are.

looking ab fab.especially that tripe. years back i got one of those because i couldnt source a 1/48 eduard one. well when i got it home and opened the box it appeared that the fuselage had been chewed up by a small dog. looking at your parts out of the box before modification i guess they all looked that way. you are doing a superb job fixing her up my friend.

Thanks to all for the feedback, it is much appreciated! This certainly is a little of a "dog's dinner" of a kit, but that, to me, is half the fun!

I have been a little distracted by the good weather and getting work done in the garden, but I have made some progress, mainly on the rear end of the Triplane....

 First I had to make the tail surfaces. I copied the plans, cut out the tail parts, and drew around them on .020" sheet. They were cut out, then carefully sanded to the exact shapes required with constant reference to the original plans....

(https://c1.staticflickr.com/3/2808/34127663596_b3a3a90c44_b.jpg)

 The horizontal stabiliser now fits nicely between the rear lip of the turtle deck and the tailpost....

(https://c1.staticflickr.com/3/2904/34037580811_89fcc24210_b.jpg)

 The next step was to correct a couple of small details on the rear fuselage. The Triplane has a quite distinctive tail arrangement, with a small lip in front of the tailplane, bringing the turtledecking up level with it. The front of the tailplane also sits on a small deck, and has adjustment at the rear for the pilot to set the angle of incidence. To achieve this, I added two small fillets of .020" x .030" strip to the sides of the fuselage, then filled them in with PPP. A small strip of .010" card was added just aft of the turtledeck for the front of the tailplane to sit on. A little more PPP to blend it all in and this is what I have now.....

(https://c1.staticflickr.com/3/2826/34037579631_7cdfd1de1e_b.jpg)

 This is how the tail will sit....

(https://c1.staticflickr.com/3/2870/34010907592_9015d7ecc2_b.jpg)

 After drilling the tailplane and fin, and adding a couple of pieces of .016" brass rod, a quick trial fit showed that the fuselage was actually a tiny bit short. I removed the tailpost and added a couple of drops of CA to the rear of the upper and lower fuselage. When that was set, I replaced the tailpost. Another dry fit shows that it is now in the right place.

(https://c1.staticflickr.com/3/2902/34037578301_f8286cb5f0_b.jpg)
 
 As a result of moving the tailpost aft I now have to add a thin strip to the rear of the tailplane. I had though it looked a little narrow, and this explains why. I will trim a strip off the elevators and reglue it to the stabiliser, to move the join between the two pieces back to the correct place. I will also need to move the rear fin mount very slightly aft. Nothing too major, but it needs to be done to get it looking right.

 Thanks for looking in!

Thanks gents!

 Not much to show in pics, but further progress has been made over the last couple of days.  The elevators on both have been removed from the stabilisers and joined together with a piece of .016" brass rod. They can now be attached as one piece, ensuring the same "angle of dangle" on both sides. Here's the pair from the Triplane...

(https://c1.staticflickr.com/5/4189/33889190350_cf3d345c2e_b.jpg)

 Attention was then turned to the Pup tail, and the rudder was separated from the fin. The fin just didn't look right, despite being very close to the plans, so I added a strip of .020x.020" to the rear edge, and sanded down the top to lower it, with constant reference and trial fitting to make sure the rudder length matched the total height of the fitted fin and fuselage. A brass rod pin was then added at the front to give a better, more secure fit.

(https://c1.staticflickr.com/3/2889/34115914522_98e1fae0c7_b.jpg)

More work was done on the cowlings, and the holes under the Triplane cowling were measured, marked and drilled out, along with opening up the Pup's cowling.....

(https://c1.staticflickr.com/3/2864/34142404351_b6b692c99f_b.jpg)

I did take pics of the process on the Tripe, but once again, my phone seems to have eaten the pics! Basically, they were marked out in pencil, drilled out with a small bit, then enlarged, until I was able to remove what was left between the holes with a new no.11 scalpel blade and clean up the openings with a larger drill bit used as a reamer, and the scalpel blade.

 Finally, all the holes were drilled in the wings and fuselage for the Pup's struts

(https://c1.staticflickr.com/3/2807/34273151075_929758a6cb_b.jpg)

 I think the next step will be drilling the rigging holes, before starting with painting the undersides.....

Thanks Rick, I just get a lot of time off work, so that helps!

 Another fruitful afternoon with not a lot to show.... however all the rigging holes have now been drilled in the Triplane.
 I promised a "how-to" guide on another forum, so I will go into a little more detail than usual here to hopefully give a guide to those just entering the WWI modelling scene......this is, however, only MY way of doing it, not the ONLY way, so feel free to adapt it to your own needs!

 I started with the centre wing. The problem here being that I need to get a straight run for the flying and landing wires through the centre wing, but only have the plans and measurements from them to do it.......hoping that when the wings are in place they will match exactly! Obviously this requires careful measurement for both drilling the holes and mounting the wings. Using the Datafile plans, photos and pics from the WnW website, and pics I took myself at the RAF Museum, I worked out that the landing wires pass through almost exactly halfway between the struts - (that should be pretty straightforward to assume as the gaps between the wings are the same), and since they attach to the wing at the centre of the struts, both top and bottom, they should be drilled level with the centre points of the cabane and wing struts where they pass through the centre wing - a straight pencil line was therefore drawn to mark that point . The bracing wires from the fuselage attach to the rear spar, which also forms the front edge of the centre cutout, and the mounting point for the ailerons, so it was easy enough to pencil in a line between the two,giving me my first reference point, and they are in line with the flying and landing wires, (fore and aft), giving me my second.

(https://c1.staticflickr.com/5/4164/33908366250_450400b46a_b.jpg)

The hardest part now done, I continued with the rest of the fuselage attachment points. Care is needed, double check your references and compare from different angles......the rear bracing wires for the centre wing attach to the upper and lower fuselage longerons at the same place (fore/aft) so once one had been marked, the others had to match...check the marks by lining up a straight edge on them and making sure the straight edge is parallel to the trailing edge of the wing - if it isn't, adjust the marks to make it so before drilling the holes.

(https://c1.staticflickr.com/5/4182/33450620404_427e72ee9f_b.jpg)

 One other very useful tool for marking rigging holes is a set of dividers These will ensure that distances are equal, especially in this scale - it is almost impossible to accurately measure with a ruler - which side of the line is 2mm....left, right, or on it? Use the dividers and make a small indent in the plastic where the holes need to be - they will be the same distance apart, and you will have a guide for the drill bit to sit in when you start drilling. You can also make sure that the lines will be positioned correctly just by sight, by placing the dividers equally either side of the fuselage centre line..

(https://c1.staticflickr.com/3/2886/34292197175_e4ab7c23e9_b.jpg)

 That's it for today, I hope the info is useful to those who need a little "push" to get them into rigging!

Thanks Antonio, Terri, and Rick, for the feedback!

 A little more progress now as I finally got the flower beds in front of the house planted and mulched this week!

 I found a spare set of PE for a Sopwith 1 1/2 Strutter, which included the nose inspection panels. Since these were very poorly moulded on the Triplane, I used them. I also gave the sides of the nose a skim of PPP to blend them in and also bring the nose closer to the correct width.

(https://c1.staticflickr.com/5/4172/33663407493_b77fe9c30d_b.jpg)

 A blast of white over everything to see what still needed doing, then yesterday I spent a few hours sticking strips of 0.5mm masking tape on the undersides for the ribs.

(https://c1.staticflickr.com/5/4174/34509971855_de1ebd426a_b.jpg)

 Once that was all done I still had time to blow a coat of Misterkit CDL on all the undersurfaces, and later last evening, removed the masking - a much quicker job than applying it!

and all done..

(https://c1.staticflickr.com/5/4187/34379598121_ef887e0e91_b.jpg)

 I hope to get a final thin coat of CDL on all of that later today to mute the rib tapes a little, then on to the upper surfaces.

Thanks for lookng in!

Thanks Manni, Rick.

 Some more progress, colour on at last! After completing the undersides, I got some paint on the uppersurfaces yesterday, PC10 for the Pup and PC12 for the Triplane, both Misterkit colours.

(https://c1.staticflickr.com/5/4168/34418866252_8b15b77433_b.jpg)

(https://c1.staticflickr.com/5/4184/34418866182_50956b07c2_b.jpg)

I then got the aluminium on this morning and have been looking for bits and pieces to do since then.

(https://c1.staticflickr.com/5/4168/34194580300_0737508c4c_b.jpg)

 The cowling inners and undersides have also been done, but that's all for now until the paint is dry enough to mask and I can get the red on the Pup nose.

The "bits and pieces" that I decided on was making a start on the guns. I have one Aeroclub and one MiniWorld. The Aeroclub has had the grip cut and filed to form the attachment points for the windscreen. I then noticed that the MiniWorld gun is wrong...the cocking handle is at the top instead of underneath. So, I cut it off and CA'd it back on in more or less the correct place...

(https://c1.staticflickr.com/5/4181/33737717914_0069eb8df8_b.jpg)

 Hopefully it stays on, but it's no big deal if it doesn't it will not be seen behind the windscreen!

Finally toady, I attached the Triplane's tail......

(https://c1.staticflickr.com/5/4170/34418946922_510828f455_b.jpg)

 Tomorrow's first job will be to mask and paint the Pup nose, then maybe start on the struts.

Thanks for looking in!

sorry to comment so long after your response but i must say that taking these old kits that look chewed by a dog and making them into prize winning models only attests to your skill as a real modeller not to be confused with a kit assembler. a modeller delights in correcting and/or manufacturing parts to make something into an amazing work of art. it seems most people these days want only a perfect accurate kit they can glue together without any trouble paint and display. i am more like you so i appreciate your work , to be honest i rarely even look at wnw build they mostly look all the same not that some guys dont go above and beyond with them.but whats truly impressive is making nothing look like something.

Many, many, thanks to all for the kind comments, they are very much appreciated!

After feeling pleased with my progress, it was only natural that a couple of backward steps had to be made! The cowlings were not good fits, the Triplane was particularly bad, requiring quite a bit of PPP......

(https://c1.staticflickr.com/5/4164/34229301680_a98f48922e_b.jpg)

 the Pup not so bad, merely requiring a little sanding of the top and lower corners of the fuselage to match the curve of the cowl....

(https://c1.staticflickr.com/5/4156/34453599162_cb40cc9802_b.jpg)

 That, of course, meant repainting the aluminium on the Triplane

(https://c1.staticflickr.com/5/4157/34484918831_3b679e22dd_b.jpg)

oh ***! Yes, I got careless, now I need to repaint the wings too to get rid of the aluminium overspray. What a plonker!

 Oh well, this afternoon's job is clear then.....

 I was going to put a gloss coat on these today, but something just didn't look right with the Pup's nose I thought it was just an optical illusion at first, caused by not-quite-perpendicular edges to the red on the cowling, so I touched those up,

(https://c1.staticflickr.com/5/4179/34272298090_064c5c3335_b.jpg)

 but it still wasn't looking right. I then put a square on it...

(https://c1.staticflickr.com/5/4173/34616880416_ee44b9d710_b.jpg)

There's the problem - the nose looks as though it's turned up because it is! The nose is on a straight line from the rear decking, instead of being parallel to the top longeron.
 Remember I've already sanded down the top of the forward fuselage to fit the cowling, obviously it needs more. So I removed the cowling and engine, added some tape to mark the line of the longeron, then sanded the top of the forward fuselage a little more.....

(https://c1.staticflickr.com/5/4168/34272289610_03d7844a54_b.jpg)

 With the cowling taped back on it looks much better now...

(https://c1.staticflickr.com/5/4171/33815240534_5595be52e8_b.jpg)

 The engine and cowling have now been replaced and I'm waiting on those to dry properly before masking off and repainting the red.

Thanks for looking in,

Ian

Post by: IanB on May 18, 2017, 11:30:31 AM
 I gave these two a gloss coat yesterday, so today I was able to take the next step - adding the fuselage decals.

 The Pup was easy enough, or so I thought. The blue of the kit decals is far too light, so I had to find something else. The aftermarket sheets I have don't have any fuselage decals big enough without the white outline, so I had to look elsewhere. The answer, strangely enough, came from the Airfix Pup! I built an old blister pack Pup a few years ago and the "Anzac" decal disintegrated. I contacted Airfix who sent me a new decal sheet, but it was for the rebox RNAS version so it was no help..until now! The blue is still a little too light, but acceptable, so I have used the roundels from it on this one.

(https://c1.staticflickr.com/5/4180/34685457316_b61b506368_b.jpg)

 Unfortunately the white stripe around the fuselage is not provided as a decal so I will gloss coat these tomorrow, and when that's dry, I'll mask off the stripe and spray it.

 The Triplane was relatively simple in that the new issue decals are pretty good. The one flaw was the serial number, which was far too large.

(https://c1.staticflickr.com/5/4194/34685456166_c504b4f89a_b.jpg)

 I have a sheet of Pegasus RFC/RNAS serial numbers, but unfortunately there is no "N", so I had to use one of the spare ones in the Pup kit. It's a little small, but far better than the kit decals.

(https://c1.staticflickr.com/5/4169/34685454826_f3fb88462b_b.jpg)

That still didn't look right, so I moved the numbers closer together and trimmed the white backing panel.

(https://c1.staticflickr.com/5/4159/34594388491_f788cacda0_b.jpg)

 Not perfect, with the slightly smaller and bolder "N", but it's far better, and will suffice - it really isn't too noticeable to the naked eye.

  Thanks for looking in!

You are doing a remarkable job with kits that really show their age. I have these two in my stash and have been afraid to tackle them because of the amount of correcting they require. You have provided me with both inspiration and a tutorial!

Thanks folks, much appreciated!

I have been a bit quiet lately 'cos I have actually had to work! Then there's the garden, now that all the wrong things are starting to grow.....I have got a few bits and bobs done though. The Vickers guns are on, and the white stripe around the Pup has been added, which would have been so much easier had I realised there was no decal for it before I painted the PC10. My main worry of course, was having the tape remove the decals, and I got all of it off no problem..except the very last piece which tore a roundel. In fact that piece was so tacky it even left a sticky mess on the paint! I managed to salvage the torn piece and hopefully with a little touching up it won't be noticeable.

Thanks Stephen, I'm hoping that I can get a good bit done this week

 To that end, today I started preparing the Triplane for getting its wings. I spent an hour or so measuring and setting up the Aeroclub jig to get the upper wing in the correct place. Somewhere along the line the nose is a little short, so I decreased the stagger a tiny bit to bring the upper wing back to where it should be relative to the nose and get the "look" right.

(https://c1.staticflickr.com/5/4228/34688769930_1475aa913d_b.jpg)

 That was the easy bit. I then had to think of someway to mount the centre wing accurately, as I have removed the lumps on the struts which Revell provide. I eventually came up with a plan involving a piece of thick plastic card, cut out to fit around the jig sides and fuselage. It was bent to match the dihedral of the wings, and two slots were cut in the rear edge. To support the wings I squared off the ends of a couple of pieces of thick plastic rod and attached some more thick card to the ends, making sure that the rods were perpendicular. These rods will then fit in the slots I cut in the base piece, and because they are a fairly tight fit, will be adjustable for height. The plan being to line everything up, then glue the rods into the slots to fix their position. The centre wings will then rest on the top pieces of card which will support them while the glue dries.

 That's the plan, anyway.....
 After I'd done that I decided to dry fit the centre struts. It's lucky I did, as they're too short! I have added some plastic rod and will tidy it all up tomorrow when it's dry, and repaint them.

Thanks for looking in!

I do love seeing how others make jury rigs to solve problems, even when they have other better jigs to hand. Very ingenious and exactly the kind of thing that I might have done in your place. These models are going to be well worth studying when they are finished.

Thanks Lance, Antonio, and Stephen, for your comments.
 Unfortunately the jig didn't work out too well. This is proving to be by far the trickiest wing-mounting operation I've done to date. The single struts make fitting them easier, but then it lacks fore-aft structural strength. I've made a couple of failed attempts (I did take pics but my camera has eaten them!) but I think I'm on the home straight now. The biggest problem has been keeping the centre struts in place - of course this would have been resolved if I'd simply followed my usual procedure of pinning them, but for some reason I didn't!
 I tried fitting all the struts first, with the intention of sliding the centre wing over them when dry. Then I realised that it wouldn't be possible to add the centre wing with the jig in the way. (doh!)
 Then I tried with the jig in place but it wasn't working out and I would have had to tape the wings to the jig, defeating the object of having it adjustable.
 I tried adjusting the Aeroclub jig to use it for the centre wing, but that wouldn't work as the bottom of the wing rail hit the little clamps that hold the wings in place before I could get the gap narrow enough.
 Finally I added the centre wing with the struts through it loosely. That was very awkward as the struts kept slipping out as I was trying to fit them, but I eventually got them all on and left it overnight to dry.
 This morning I added the upper wing and clamped it in place. that is now sitting to dry. The centre wing is still not fixed in place. I'll adjust it and fix it permanently once the top wing has set. Hopefully the struts will stay in place during that operation!

So here's where it is at the moment...

(https://c1.staticflickr.com/5/4264/34293634394_1053e06cbe_b.jpg)

 This one is proving more of a challenge than I'd expected, I should have put a little more thought into pinning the struts and maybe even worked out a way of attaching the struts to the centre wing before fitting it all as a unit, but that would have been very tricky to get the strut angles, and therefore the wing stagger, correct. Of course, I could have just left the mounting lugs on the struts, or reduced them so they were less noticeable. Maybe even marked the struts with the position and angle of the mounting lugs before removing them....

 Anyway, hopefully it's on the home stretch now!

Thanks for looking in!

Post by: IanB on June 07, 2017, 05:57:45 AM
Very true Stephen!
 
I think I've cracked it!
 The struts stayed put and I got the centre wing adjusted and glued in position using PlasticWeld and a small brush. After leaving it for an hour or so I used the same small brush to add some thin CA to the joints. Another hour or so and I have now added some PPP to the wings to fill the rest of the gaps. That will be carefully cleaned up when it's dried and then touched up as needed.

Before I remove it from the jig I'll add the centre wing drag wires and the landing wires, just to give it a little more rigidity.

Thanks folks!

 I've had another good day on the Triplane today, touching up where needed, and then working on the rigging.

I left it in the jig for most of it as there is virtually no strength to the top wing attachment and it would be very easy to pull it out of alignment with the rigging. The first job was to attach the centre wing drag wires and cabane rigging wires to the fuselage.

(https://c1.staticflickr.com/5/4209/34354047113_b7be469650_b.jpg)

 These were attached as usual by dipping the ends of the lines into thick CA and then slipping them into the predrilled holes. Once dry, they could be tensioned, the ends being held in place by small clothes pegs, and thin CA was carefully applied to the underside of the holes with a sharpened toothpick. My camera seems to have eaten that pic, too....

Once those had set, I repeated the process for the landing wires...

(https://c1.staticflickr.com/5/4261/34354045243_0221447345_b.jpg)

and from underneath

(https://c1.staticflickr.com/5/4241/34354043973_0d9bb7aea9_b.jpg)

 To do the flying wires I had to remove it from the jig. The same procedure though....

(https://c1.staticflickr.com/5/4250/35123956866_1574e39650_b.jpg)

and it looks as though my measuring for the holes in the centre wing was pretty much spot on!

(https://c1.staticflickr.com/5/4261/34354047803_cd9101f346_b.jpg)

 I was careful not to drill the wing straight through, perpendicular, but estimated the slope of the wires from the plans and drilled at the appropriate angle so the wires continued without a bend. It seems to have worked as both sets of landing and flying wires form a straight line with no kink through the centre wing.

Thanks for looking in!

Many thanks gents, your comments are much appreciated! I have, at least so far, drawn the line at double wires for the rudder controls.....

Work is starting to pick up now, so no modelling time last week, but I did get a bit done yesterday in preparing the Pup for the upper wing

 The jig was adjusted and the Pup entombed in its cage..... I then added all the rigging wires to the lower wing and fuselage.

(https://c1.staticflickr.com/5/4284/34571794923_ecdfee4b76_b.jpg)

(https://c1.staticflickr.com/5/4251/34538592024_9ecd97ed78_b.jpg)

 I decided it would be a good idea to thread the lines through the upper wing before adding the struts, as some of the angles are quite tight and it is far easier to thread the lines without the struts in the way.

(https://c1.staticflickr.com/5/4278/34538595364_74a29a5c13_b.jpg)
 
 They're not tightened yet, that will be done when the struts are in place. I then started to add the cabane struts, and discovered they are all a tad too long. The gap between the upper wing and the top of the cowling should be 6.5mm and it was 7.5 so I'll have to shorten them all slightly That will be the next job.

Thanks for looking in,

Ian

Ian,
    There's some brilliant improvisation going into this project. I found the Tripe touchy to rig in 1:32 scale, your double runs in 1:72 and the center wing pass through alignment are mind blowing in 1:72!
    Impressive building, and a shining endorsement of the AeroClub Jig!
Cheers,
Lance

Post by: IanB on June 20, 2017, 06:50:12 AM
Thanks Lance, although I have to admit the alignment was more luck than judgement though!

 I came home from work today and decided to tackle the task of shortening the cabane struts.  The front two went easily and were left clipped in place as I did the third, which also slipped into place nicely. When I put the jig down I noticed that the two front struts had fallen out. One was lying right in front of me on the bench, alongside the fourth strut, but where was the other? I searched everywhere, cleared the bench, scoured the floor, checked my clothing, even checked the jig itself to make sure it wasn't caught up in it somehow....3 or 4 times, but still couldn't find it. I decided it had gone, and the only solution was to make another, but I didn't feel like it at that moment. I went and took a shower, came back and decided to replace a couple of wires which had pulled out while fiddling with the struts. Duly done, I put the jig back on the bench.....and there were 3 struts sitting there...the fourth was were I'd left it, clipped into the wing! I have no clue where the strut had been on its little sojourn, I find it hard to believe that it had fallen into the cockpit as I was holding it upside down when they fell out! I guess I'll never know the answer to that one!
 Anyway, now I had all 4 struts again, I continued with my original plan and finished the adjustments, then glued them in place......

(https://c1.staticflickr.com/5/4285/35372703066_3257795323_b.jpg)

 The wires are clipped in place to stop them pulling out, but they won't be tightened and secured until the outer wing struts are in place. Hopefully a job for tomorrow!

It is, Juan, but it's a bit of a masochist, so it's enjoying it!

 The wing struts were trimmed this morning, then installed. This afternoon the landing wires and all the cabane rigging wires were tightened and fixed in place using thin CA applied with a sharpened toothpick.

Sounds like a case of the Lonesome Strut…… Very impressive rigging Ian: the jig is obviously a great help with thread - it seems that rigging like this in this scale would probably be nearly impossible without it.

Thanks Rick and Stephen for your feedback.
Unfortunately I've been busy with work lately (it's that time of year!) and also had to go out to Wichita, Kansas, for a week for annual recurrent training. Between that, trying to keep the garden (yard for Americans!) tidy, and reposting all my old PB pics to Flickr and updating all my old threads, I haven't had any time for modelling for a while.
 However, I did decide to forgo the garden work today (my excuse was it has been too humid. That's my story and I'm sticking to it!) and finished the rigging on the Pup. I drilled through the lower wing at the inboard end to pass the flying wires through to the undercarriage mounts and then fitted all the flying wires.

Thanks for the feedback folks, very much appreciated!

Well, Gents, I finally have another update!
 I took a look at the undercarriage as supplied by Messrs Revell and HR (Puffinstuff?) The Pup's is useable, although I'll make another spreader bar and axle. The Tripe's however, is not

The Tripe's is the lower pair shown below, after I had already attempted to modify one of the kit legs to see if it could be made to work....

(https://farm5.staticflickr.com/4327/36183710645_e966f3bb92_c.jpg)

Unfortunately, the legs are too long and the angle between them is wrong. Apart from that, they're not too bad...

So I made another pair using my usual method of brass rod and plastic strip. Here is the new pair, along with the old, plus the kit spreader bar and replacement...

(https://farm5.staticflickr.com/4294/35379595063_fb46565184_c.jpg)

Somewhat of an improvement I think!

 After faffing around with those for a while I decided to finish off the tidy up of the upper wings following the rigging. They have now been painted and I hope to get a gloss coat on them tomorrow

(https://farm5.staticflickr.com/4330/36183714885_87f41cf544_c.jpg)

(https://farm5.staticflickr.com/4317/35379591353_f3951f8e6e_c.jpg)

 While I had the airbrush going I also cleaned up the wheels and gave them another coat of colour.

Should be all downhill from here.....

Thanks Juan and Rick...nearly there now....

The last couple of days have seen the last 2 major jobs completed:
 first the remaining decals were added on the wings

(https://farm5.staticflickr.com/4292/35465241413_9014cf37de_c.jpg)

(https://farm5.staticflickr.com/4308/35875168010_c86c271c78_c.jpg)

 The little black rectangles that are supposed to represent the inspection windows will be covered by silver coloured decals to make them at least a little more convincing. I did think long and hard about adding clear sprue inserts to both aircraft's wings but decided it really wasn't worth the effort: there are 5 on the Tripe's wings and 4 on the Pup's.

 Then today the elevators and rudder posts were fitted and painted, followed by the undercarriage.

 A little more progress this week, in that the undercarriage on both has been rigged...

(https://farm5.staticflickr.com/4420/36222476202_d91d53de0b_c.jpg)

 Unfortunately the Tripe's is slightly off centre, but it'll have to stay that way now....

I also got most of the Tripe's aileron rigging done. It just needs to be trimmed off. I made a bit of a mistake here, in that I assumed that the wires would continue over the horns and back to the ailerons. Unfortunately after looking at pics only the Pup's underside has this set up, so I now have to carefully tidy up the holes, which should have been done before adding the decals.

That is super rigging Ian. Like the rest of the build it is difficult to appreciate that this is 1/72 (ie the True), scale.

Many thanks to Filip, Antonio, Rick, Ian and Stephen for the kind comments!

The Triplane is now finished! I added the last of the tail rigging this past week, then this morning I added the final bits - wheels, prop, pitot tube and windscreen. The latter was cut from clear plastic packaging, CA'd in place, then I ran the smallest brush I had around the edges to give it the padded leather look. Both were done at the same time, so the Pup also has her windscreen now.
 
 Here's the screen being shaped. I left it attached to the main body of the plastic to make it easier to hold, then snipped it off and gave it a final clean up.

and here it is in place and painted

as you can see, I should have filled the indents in the fuselage for the cabane struts as they are too far inboard, but by the time I realised it was too late and I don't want to risk messing up the surrounding area to try to fill the gaps. It really isn't too noticeable in "real life", but just a tip for anyone else attempting this one!

and here she is, a few last touchups still needed but that's all.

 The weather is very dull today, hopefully tomorrow will be sunny and I can get some decent pics and post her in the completed section.

As soon as I get the PE for the Pup I will continue with her.

Thanks for looking in!

Thanks Rick!

I finally got back to the bench this morning and finished off the control and tail rigging 

She's sitting upside down now waiting for the wheels and tailskid to dry, so tomorrow I hope to complete the touchups and post the RFI pics!

 She's now taken her place in the cabinet, replacing the rather sorry looking Airfix one, which has served its purpose well.

More pics in completed section, many thanks to all who have followed along and given encouragement!
