I don't think that's a compression buckling failure, I think it's plain ol' bending from torque imposed by the tailwheel.Gordon, I was only going by Tom's pictures in #175 where there are two tubes with a column buckle. His X brace reinforcement cuts the column length of four tubes by half. By welding the X in the center there is additional stiffening. The damage is caused by torsion on the entire aft end of the fuselage but when you narrow your focus to one tube at a time you can see the column failure.
Switching gears, so to speak. I'm starting to fabricate the landing gear. What exactly is extension of 3 inches in the 3" extended gear?
Is the axle attachment 3" farther from the pivot points, or is the 3" measured vertically?
I can't seem to find actual dimensions.
Thanks,
Vic
Nice looking project!! I am getting ready to build my axels as well. Any pictures you can put up on how you cut and flatten the cabane slot in the axel would be a great help to me. Thanks!

this is what I have on the sport trainer drawings. About heating and flattening the tabs

compare the 2 gussets... much longer... atlee's even has a larger tube onto of gear leg to spread out the force
Why did I miss your post? I just ran to my hangar to take some pics of my 6'' certified 1.250'' gear. Looks kind of similar to what you've built.
