Making replacement wing ribs
#1
Thread Starter

My Feedback: (1)
I recently crashed my U-Can-Do 60 and the wing ribs aft of the spar are almost all destroyed. What is the best way to make multiple ribs? I have a band saw, table type jig saw, table saw, chop saw, belt / disc combo grinder, and drill press. I was thinking of making a very wide rib section and then using the band saw to slice off the narrow ribs, has anyone done this and does it work?

stack up sheet balsa the correct thickness of the ribs. trace the rib on the top piece, stick 2-3 pins down all the way thru all the parts. cut them all out at the same time on a band saw (up to 3 inches thick or so). then use a sanding disc or block to bring them all down to exact size. Also cut any spar notches on the bands saw when they are pinned together. When you take them apart you will swear they were from a laser cut kit

The wing alone can be purchased from Tower:

This wing has a constant chord; hence, all ribs have the same dimensions.
Here is how to make them:
