Here is my handy homemade "mini-router" table. I needed something for opening up lightening holes in plywood formers and fuselage sides, but I'm too cheap to spend 50-100 buckson a store bought unit.

Nice flat piece of wood,plus a square stick leftover in my scrap bin resulted in a nice little table.Clamp my dremel tool flex shaft to the frame on the bottom, with the cuttingbit up through the hole.....presto.....homemade hobby size router, just clamp'er down to a bench and go. Took me an afternoon to build, and $4 invested. Incidentally, a drywall bit works nicely on balsa sheeting!!
