Good to see you still at it Steve!!

We are at identical stages in the build - I too now have a finished wing bar the wing dowels and a 2-half, planked but unsanded fuselage. I'm just contemplating the joining operation and I've just been out to buy a few more small spring clamps to help with alignment - my fus bows out a little at the very front and back under the tight curves of the planking - does yours??

@ Phil , i guess we all have had that same issue when joining the two halves , but nothing a few clamps can't handle.

great to see you back in the building seat Steve !

To keep myself on track i have a special rule : When i end a building session , i allways plan the next job .I also try to do something every day,it doesn't matter for how long...Remember starting is the hardest part.wink

Yes it's a good philosophy Dirk. I do try to follow it myself. And I often find that a long hard week at work can re-energise my enthusiasm for building.

I got the fuselage halves joined today. Former alignment was not perfect, but good enough I think.

Phil - Yes I found the same thing - the front and back had sprung out a bit, and twisted a little, so needed a bit of clamping. I also found that I needed some big clamps in the middle - around F4 and F5. These will produce some nasty marks in the planking, but then there's going to be quite a lot of filler used on my fuselage to cover all the planking imperfections anyway!

Looking good Steve,

When you guys are joining the two halves, are you just ensuring that the keels are straight? Mark 1 eyeball method?

I've just started planking, and have used ammonia to assist the balsa in adopting the curve without too much stress. Fingers crossed.

Cheers

Ade

Hi Ade - yeah thats all I did - the two sides were flat on the board between F2 and F9 - the bow only appeared at the extreme front and rear where the curvature of the planking is greatest - so between F2 and F1 at the nose, and between F9 and F10 at the tail.

For this reason, I also just clamped mine (in the vertical - like Steve here!) happy that 90% of the fus was true - and that the clamps would do the rest front and back.

img_20200223_165107751.jpgI have now finished planking the top part of the fuselage, and fitted the elevator servo and hinge mechanism. Now turning my attention to how to create those tailplane fairings. I decided it might be easier (and maybe half a gram lighter) to construct them them 1/8th sheet rather than 1/2 inch solid balsa.

Not but progress recently, but I managed to add the 'lids' onto my tailplane fairings yesterday.

very smart Steve - definitely one of the more tricky features on this build - interesting to see the different approaches taken by various builders. We're at a very similar stage - we'll soon all be glassing and painting!

That poor Spitfire fus sat in the corner crying

Very neat building though Steve, good work!

I did start on the Spit wing Andy. But everything has had to stop to concentrate on getting this Sabre done in time.

Even though we're getting close to glassing, it still feels like there's a long way to go. And we're going to be interupted by some flying weekends soon!!

It is a relief when that last plank goes in!

So I have now turned my attention to the pilot. I found this head on 'Thingiverse', and scaled him up to approx 1/10th. Unfortunately, he's not as tall as I need him, so he's being extended with a bit of 1/2inch balsa.

Today I've been working on the wing seat area. I cut a bit more out of the fuselage sides to be sure that the wing was resting on the inner ply formers. I figured I can add it back later as 2 more planks. I also found that I had to sand the formers a bit to get everything to sit down nicely.

Have now added the 2 front dowels.

Nice and tidy there Steve, innovative solution on the tailplane cheeks.
