I shared this tip with a fellow flyer yesterday, I have been doing it for years, he tried it and was thrilled. Maybe it will help others.

Need to cut out balsa or plywood parts?

Want smooth cuts?

1. Go to a jewelry supplies shop - buy a 4" deep throat ‘jewelers’ saw. Then get a package of blades - about 40 teeth/inch.
2. Cut out a piece of plywood (1/4") 4" x 8", cut a shallow V cut into the ply (about 1/2" wide and 2" deep).
3. Clamp this piece of ply to your bench edge (horizontally), place the wood to be cut on it, over the V cut.
4. Hold the saw vertically, sawing up and down, following the marked lines - it is just like a coping saw!
5. Turn the piece being cut, as you progress - and as if by magic, SMOOTH cuts.

You can cut almost any thickness, just hold the saw blade vertically. If you need an inside cut, first drill a hole - insert the saw blade through the holes and re-attach the blade to the saw frame, and cut.

This tip is for those without a scroll saw…
