RE: Uncle Willies C-130 scratch build 65
When I cut balsa or ply pieces I will always leave a little material, then use sanding blocks to finalize the part. this does not take long and does a superior job even to a scroll saw. Get yourself a couple of T-bar sanders, and not only glue sandpaper to the face but you can glue some to one side of the "upright" this way you can use it to keep your sanding at 90 degrees, especially if you are sanding stacked parts such as ribs or whatnot.
You can also get creative, glue sandpaper to a piece of pipe for inside jobs, wing fillets, etc. cut apiece of pipe in half, glue sandpaper to the inside and it is good for rounding leading edges of stabs etc. A lot of kits come with "jigs" made of light ply to sand the hing line of the control surfaces to a beveled edge, just three pieces of wood glued together. I have lost mine but maybe someone could post some plans for one.
Looking forward to seeing some pics.
