Im sitting at work thinking, what if I could find a piece of aluminum, or sheet metal and trace the rib on two peices of metal. I would cut them both together so they would be a match. Make kind of like a balsa sandwich with the metal on outside, rough cut and then sand. Would that keep everything straight and level? What do you guys think? Thanks
Yep. Aluminum is fancy. Some plans have you make a plywood inner and outer former and then bolt them together with the basla ribs between. This works even <u>better</u> with tapared wings as then the taper is pre-evened up. You want to make the "masters" 1/16" oversize to allow for final sanding once the ribs areglued up to the spars.
You don't even need patterns, just mark the profile on the outer twoand sand away.
