billy's plans built sonex 1735

I also added a strip of aluminium to the short side of the skin. Taped it in place so both edges met up evenly before pulling a vacuum. I used a length of 42mm steel water pipe to bend around but think 38mm would have been better.

Are you using steel pipe or plastic pipe? I'm close to bending my leading edges as well. Look forward to photos and updates.
Thanks.

1 1/2" pvc......is your skin cut and drilled? Billy

Haven't cut the skin out yet - still 4' x 12' sheet. My plan is to cut out but leave extra length on one side and cut to final length after bending. Was also planning to drill before bending.

Didn't work for me, no matter how hard I clamped the pipe down. Nature has it's way of evening things out.

Randy has finally convinced me my method is flawed. I will add length to the short side. Guess I’m pretty hardheaded. Thanx to everyone for helping me with this. Billy

Ok made some of the last few pieces for the wings. The long piece with matching holes is for the 3/4” extension to the one side of the leading edge skin for bending. It should make the bending even. Also wing tip blanks and landing gear fairings.

First one worked. Thanx all

[Rofomoto]

Looks like it’s gonna work.

Couple small little nose rib dents. I’ll try to fix when I take it apart to deburr.

What # drill bit for leading edge skin have you used pre- dimpling. Thanx billy

Either #30 or #31. I found #32 to be too tight.
