A router is the only tool I did not feel I NEEDED. I have accumulated a lot of tools over the many years but the cost of a good router, table and bits plus I never saw a need for it in building RCs until now. I'll just trace the pattern onto the balsa sheet and use ether the jig saw or the band saw to cut them out.

Ron, I am going to try to find that Catalina build thread and see if I can't get some ideas. I have built a lot of models over 30 years but it was always with plans, pre-cut parts and building instructions. I think I will trace the ribs and formers onto thin cardboard and then trace around it onto the wood and saw them out. Someone suggested tracing them onto formica but a 4X10 sheet was $125 at Lowes and the would not sell anything smaller. I only need about 2 square feet not 40. I tried a piece of thin floor tyle, but that doesn't work to well either. Of course any and all suggestions are appreciated. I will try almost anything once.
