Wing Jig Pic
« on: February 06, 2016, 09:30:25 PM »
I made this out of 2" "C" channel aluminum with 1/8" wall. The top edge was milled to a thickness equal to the kerf of my jigsaw blade (.050") so I can just cut little slots in any rib and get it on the jig. The leading edge is two pieces of channel so I can make a taper or straight leading edge wing. It sits on a 1/2" glass table top that is shimmed to be flat.

You're assuming that extrusion is straight and not twisted or anything? I've seen some that were WAY not straight AND twisted.  y1 Steve

I like the idea.   Yes some places you have to look through the rack to find straight pieces.   But why not just leave the edge at full thickness?

Being a machinist, I checked them for straightness and they were certainly milled straight after that. I milled the edge because I didn't want a big slot on the trailing edge.

Well it's finally starting to look like something. Not sure how to finish the top. I think I'll just put a 1/4" sheet on it and round it off and go bubble canopy. This is a one off 92% TunderGrazer 40 so I don't want to bother with molding bucks for it. My first full fuselage, it's funny I've boxed the fuse on 3 sides and it's still pretty flexy, will adding the top give it the tremendous stiffness full fuse is famous for?
