RE: Cutting multiple angles on balsa stick build ups?
I mark them, cut them with a scroll saw, and finish them to the line on a 6" dia. disc sanding table, after that I glue everything together with thin CA. Next I pull the work from the table and run a corner glue joint with medium CA in every corner and kick it off. I don't ever worry about the excess CA on the balsa because the way I sand flat surfaces and fuse sides is like cheating its so easy. I place 6 or 7 sheets in a row of 9" x 11" 180 - 220 grit sand paper on a flat surface like glass from an old sliding glass door with 3M 77 spray adhesive. I make sure not to allow any of the sand paper to overlap at all, then I work the control surface, stab, or fuse against the table instead of using a sanding block against these items. this type of sanding will take everything down so fast and true, you just won't believe it. I guess I have been doing this for 20 years or more and I have done it on stuff all the way up to 70 % airplane size with the same results. Here is a just glued picture and a couple more just a little while later.
