M.L.G. Aft Fittings (AFT)

This afternoon i completed the landing gear fittings. I cut the tubes, where bolts will be inserted, to an approximate length, they will be timmed after being welded to the brackets.

Built today the main landing gear aft fittings. Thay are made by two 0.080 inch, 4130 steel plates.
First of all i slightly bend plates, (3.5°) where the landing gear will be bolted on. To have a greater control, of where fold start, i do two small cuts with holes in the ends, along the folding line, so to create a weak point. Done that i locked all on vise and with a light rubber mallet i've bent plates.

Preparing for bending...

All holes done! Sometimes i use to drill extra holes on plates, these to lock them, with srews, on a wooden board, that i clamp on drill press plate, as support when i do holes.







 





I left lugs a bit longer inside where they will be welded, these because i want weld plates on streamline tube, and even against the cross member tube at station 20-1/2...more safe!

Finally bent and completed. Now need to cut 1/2 tube to size and weld on it.
Not easy to build these two pieces, the hardest part was bending the two tabs symmetrically with the correct radius. To do this i built a jig where i 've bolted pieces on, and whit  a big hammer, i've fold lugs.
