Ian,
The fuel tanks and rigging look outstanding in place! Excellent update!

Thanks folks!
Not much to show this time around but I have been busy...drilling holes! All the rigging holes have now been done (I think!) and for the sadists out there here's the count:

Lower wings: 32 each side
Upper wings: 42 each side
Centre section and fuel tanks: 20
Fuselage: 8
Horizontal stabiliser: 8 each side
Elevators: 7 each
Ailerons: 9 each
Rudder: 8
A total so far of 232 holes at a cost of 3 drill bits killed in action! A pretty good rate! (The 10 additional holes in the fuselage for the control cables were done much earlier and haven't been included in this count!)
That of course does not include all the holes I'll have to drill in the struts and undercarriage when I make them........

I feel a beer coming on!

See you all later.....

Ian

Ian,
Much the same as the "Fee" but in this case more! I remember it well and, like you, invoked the universal pilot's solution to temper the experience once done, an ice cold one! Enjoy it, it's certainly been earned!
Cheers,
Lance

This is really going well - and at speed too. It would have taken me many times longer to have drilled all of those holes.

Stephen.

The beer is really well deserved! And a rate of 232 holes to 3 broken bits is a dream, I won't ever be able to reach that...

Thanks Borsos! I could never have achieved that rate with the drills I used to use, plus they never really drilled a hole, merely seemed to screw themselves into the plastic! I found these which are much more durable and don't break nearly as easily...

I also had an "aaargh!" moment when looking at the pics to sort the rigging out. All the plans, as I said, are for the blunt nosed, later Veh, and it was those I had been using. Upon more careful analysis, I noticed that the upper wing attachment was different on the earlier sharp-nosed Veh. You will notice from previous pics that I have squared off the rear of the centre section, and the wings butt-join against it to give a squared off rear edge.This is wrong! The earlier wings joined the cabane framework further inboard. There is no centre section frame butting against the wing, and the wing overlap at the rear is slanted. Hopefully the pics will show you what I mean a little better.....

Here is the extra piece of plastic I added to the rear inner wing edge...

This gives the overlap I need, and the slant to the inner edge. I then filled down the rear edge of the centre section, but only that part of it directly behind the opening as there was simply a shaped piece of wood between the rear wing spars, where the wings were bolted on......

This is what it looks like now. You'll see the new wing joint is level with the front inner edge of the fillet I just added, not where the kit wings actually join the centre section (that is where the later wings joined!).... A dry fit to see that it all works.....

Thanks for looking in!

232 holes!! But, things are looking good! Nice work on the upper wing.

Great catch and correction on the wing mounting! Looking better with each update. Very impressive ! 232 holes.... Probably one of the reasons I build mostly fighter types

Thanks Steve, RB, and Rick - still plugging on with this one!

Having decided that the earlier effort was not up to par and a little oversized, I decided to remake the engines. So having now received the plastic stock I needed (4mm half round and 2.5 x 3.2mm rod) I have made a start. I cut the stock to the lengths needed (the rod is 0.5mm shorter than the half-round) and glued them together, making sure that one end was flush, and that the gap either side was equal. I then added Perfect Plastic Putty to the sides and when dry, sanded it down to give me the slight slope I needed on each side of the upper crankcases .

The front and rear extensions for the prop shaft and rear accessory drive were added from 0.020" stock sheet, punched out with my 2mm punch.

I will take the edges off those when they're dry, just to make them look a little more like cast items, not something that was stuck on later. I now need to add the engine mounts, the flange around the crankcase joints, and the strengthening fillets at either end........

Thanks for looking in!

Fantastic start on the new engines. I am looking forward to your next step in the improvements!

Engines can be a pain to get right - 4 means an even bigger pain! You are doing extremely well with these so far - interesting to see how another modeller uses different ideas. Am following with great interest…

Having done a superb but nevertheless laborious and long-lasting job on the wings and the fuselage correcting the flaws of the kit and bringing everything together would lead many modellers to the point to say: Well that's it, I'll leave it as it is. It honours your skills not to rest on what's offered but to go on with that huge work and to improve the engines as well. I'd better say making four engines from scratch... hats off for that!
I go on following this build with huge interest and respect.

Rick, Stephen, Borsos - many thanks, the feedback certainly helps keep this one going!

Not much of an update this time but I thought I'd at least let you all know I'm still plugging away at it! I added the mounting points using 1.5mm channel. I know they're not really accurate, the sides should be sloped upwards towards the top of the crankcases, but a) unless you compare to a pic you won't know, and b) it's just too damn fiddly to add the small extra pieces. I think it will look better as it is rather than attempting to be a little more accurate and having joints and slightly wonky sides on the mounts! I have also added some of the strengthening fillets at the front and rear of the crankcases - again, just an attempt at getting a little more detail without ruining it by trying to be 100% accurate. Most of the front and rear of the crankcases will be hidden by either the front fairings or the radiators anyway.....

Maybe a coat of paint next, then take another look at the cylinders.....

Those should do the trick just nicely Ian , looking forward on the next up-date

Coming along quite nicely, great to see your progress.
