Great job, Tug, your build is an excellent inspiration for me!

Thanks for sharing the pictures.

Cheers

Thanks Tug for the explanation - I think I'll wait a while to try but the effect is definitely convincing. I'll take the ladder one rung at a time. I come from the very forgiving world of wood modelling. Plastic terrifies me!

Your SE5a is utterly brilliant- I guess you have seen this or similar - https://www.youtube.com/watch?v=nVx4C4VDBVU

Hi Ondra and Alistair - thanks for looking in. It's nice to hear from you. I confess to having not had time to take a look at what others are doing myself which I do feel a bit mean about but bear with me guys I'll get there eventually  :-[

I haven't done a great deal but I do have a bit of a 'grin on'  :) It's also amazing just how long it takes sometimes for the 'brain to get in gear ::)

I bought this assembly fixture off my friend Paul.


In the process of assembling this fixture I felt that holding the wings in a firm fixed position laterally could prove a problem so reverted back to using my original balsa fixture that was used on the Camel build.


The problem experienced with this was its low level to the bench and the difficulty in holding it at varying angles. I could only use a vise to hold it vertically


It was pressed into use on the Nieuport build with a similar degree of restriction so as the time approached to get that top wing on I began to think about modifying it to allow more movement. I thought about buying one of those 360 degree stands that Lance has but as usual the last minute casting about in the workshop led to a 'I really ought to buy a swivelling vice' kind of thought (something often considered when the need arises but a way is usually found around things and the moment is lost) Then the penny dropped.
Long before the Camel build I bought a piece of kit for the engineering workshop 'because it was cheap' (twenty quid) and looked purposeful. No, that's right I've never used it todate! Bingo! the lights came on. Two drilled holes later and my little balsa fixture is transformed :D

Modified to take the SE5's wider wing and a new fuse support first


It was bolted to a 360 degree swivelling table that can rotate through 90 degrees.


It must have been a very expensive kit in it's day as it is precision made with both movements having a drag associated with very close tolerance fits. It has no apparent means of adjusting those fits.  It presents a firm but gentle resistance to movement but stays firmly where left. There are two very small locks to hold it but in this use are simply not necessary. There is no makers name but I would imagine that it was designed either for inspection work or more probably for use on a surface grinding machine.


As you can imagine it's rather heavy but that too is a bonus as on a piece of non slip mat it's not swanning off across the bench


It's been fully field tested - well the tail-plane is rigged so far  ;) but the initial impression is I'm bloody chuffed. To think it sat under the bench without a thought through the previous two builds - well that's gotta be an age thing ::)

Nothing left for it now - that top wing is next!

Regards - Tug

Brilliant Tug, same principle as my "Third Hand" however a much more attractive price!

Hi Lance, It could be considered a mite overkill I guess but as you say at the right price - at least it's found a use  :D

I'm off to the pond now for a bit of (chilly) sailing - hope to be back on this tomorrow

Happy New Year to you and all those looking in  :)

Your innovation on using that piece of equipment to make a rotating jig is Brilliant! The SE is looking gorgeous to say the least. What I can see of the tail rigging looks perfect.

Hi RB, Rick, Thanks for looking in.  Yep, have to say again, a bit overkill but such a boon - it really has made things so much easier.

I used a mixture of rigging material - monofilament for the landing wires and Model Kasten for the double flying wires.
 

I did try to fit the wing with it still in the fixture but that really did prove difficult to get all the struts in the right place at the right time .....


.... so in the end I resorted to turning it upside down on the bench with the centre section supported with a small block which made the task very straightforward


I had previously came to the conclusion why the Camel wires slacked so badly. I did not have the landing wires in enough tension (I brought them through the wing and just hung a small weight on and glued them in situ.) Once the top wing went on and everything settled down after a few days, the weight of the top wing had pushed the lower wing downwards, slackening off the double flying wires - even tightening them by heating them has not improved that. So, how to get those landing wires tighter? I did the following on the Nieuport but wanted to see if it would work before saying anything. They are still as tight as could be wished for so I tried it again on this build ...

The rigging line was brought through the wing (0.3mm hole)  and then returned leaving a loop under the wing. On the end of a piece of  of 0.2mm copper wire (I used a very thin Trumpeter saw blade) a 'U' is formed and nipped up close then this is looped over the mono filament loop under the wing


By pulling on the copper wire against the monofilament being pulled in the opposite direction this kept the rigging line tight as required until finally pulling the wire loop tightly into the hole and so locking off the line. It was then consolidated with a small drop of CA either side.


I decided that doing double wires like this might cause a problem in one being tighter than the other so used Model Kasten 0.2mm line for the flying wires. Just '2 thou' difference but it looks a lot to my eye but they do have to be painted as yet so that may be where it can be disguised a little. I have not put any tubes on to represent the tensioning devices but this will be done using paint as used on the Nieuport.



Well that's it - I usually post last thing at night but I was whacked last night so now I'm off to make a start on the base and hopefully finish off the rigging

Regards - Tug

Oh what a lovely Se5a! This model became really a masterpiece. I really like your way of subtle weathering, exceptional!
I am also used to post at night when I finished my building session, just to see minor or maior flaws in the morning ... not the case here!
Best wishes

Brilliant work!
 I love the subtile weathering that brings so much depth into the plane. Great!

Great work Tug. Another masterpiece in the making. I do like your bespoke model holder. The rigging looks excellent.

Hi Borsos, Manni and Toby - thanks for looking in and those encouraging remarks  :)

No pics I'm afraid but I have had a bit of a set back.

I more or less finished the rigging yesterday - just the strut cross wires to do - and the more I looked at it the more I felt the model Kasten 0.2 mm line looked overscale. I'm convinced it was growing in thickness as I looked at it  :o

In the end I thought maybe it would look better if I painted it. I used a silver marker to deposit a drop of the ink on the bench top, picked some up with a brush and applied it. Oh bloody dear  :( It made it look even worse. I quickly got some Isopropyl  Alchohol on a brush to remove it which worked fine until I 'pinged' the line and deposited faint silver spots on the wing - Aaaarrrrghhh!!!

Stopped at that point - came in for dinner and had a long think. Went out and snipped the offending lines off back to their attachment points. It immediately looked better but how to re- rig it? Intention is to re-drill those points and fit mono filament. One thing it proved though is just how good the attachment was in the top wing - I couldn't pull those out even with small pliers before the rigging broke. My approach to get sufficient tension in will require drilling through the top wing now - just hope I can disguise the offending exit points well enough.

Ah well what will be will be - at least I haven't broke it (though it did come close to a flight test!)

Back soon with an update - improved or wrecked remains to be seen

Oh Tug, that sounds really bad :o
For my taste the rigging looked quiet good, but at least it should fit your taste.
I think, you will manage this issue but drilling will require to repaint the upperwing (hope, I'm wrong). That is the reason why I always take Gaspatch turnbuckles., so I don't need to drill through the wings.
Fingers crossed,
Manni

Hi Manni - thanks for the concern  :)

I've been mostly distracted by working on the base today but I did manage to successfully drill out all the existing rigging line holes and get the rear flying wires re-rigged though I still have to tension and glue them in the top wing. I had to drill through the wing as said but I think I should be able to disguise the four very small areas without too much problem and with having to re-paint the wing.

It's getting close to the end now - back soon
