Decided to hinge my front seat back. I almost always like Atlees designs on most things Super Cub. But his front seat mod just doesn't work for me. Had it on two planes but don't know WHY he chose to use the vertical tubes as the hinge point?
It leaves all that seatback tubing that's below the hinge point; facing back almost to the rear stick, when seat is folded down??? Makes it harder for rear seat passenger to load?
Champion hinged their seats from the front
Of the diagonal brace on bottom seat tubes. Just seams to be a better design for simplicity. Leaves an open hole between the front and rear seats.
However they just flattened the diagonal brace tube and bored a hole in it. Then bored a hole in seat tubing and put a bolt thru it all. Simple but very basic. I am going to go that route, but wanted a proper " hinge"
Our male part design, will insert into the inside of diagonal brace tube, after it is cut off, The female will get Tig welded
ontop of the seat tubing right where the brace tube was welded. Creating a proper machined hinge correctly alignment to center of both tubes. Then we will cut the vertical seat back tubes off and Tig washers onto both faces so when they come togeather all the pressure will get distributed over the washers, one washer will have a tapered pin in it for precise alignment of seat back to bottom tubes.
Here are some photos of the hinge we did today. More to follow ( used same ball end mill as I used to make saddle ring STUDS for model 1894 Winchester's!!!! ) Lol.
