Pin them down to your work surface on top of your plans and then throw balsa, ply and glue at that area until it looks like an airplane.(That's how we do it right?)
Cut from 1/8" MDF the RB Jigs are 3" tall with a 4" base and are laser straight! (who would have guessed). Pin holes are already in place. Just glue them together and get your butt back to work on that airplane! Its not gonna finish itself!
If you need some bigger RB Jigs or smaller ones, email us... we'll hook you up.
