I have wanted to build a shop made scroll saw for a long time. I haven't done so because with health problems, I didn't know if I could handle the type that you pedal or work a treadle. Then I ran across this design in an August 1986 copy of WOOD .
Self-Squaring Picture Frame Jig Torture device? Maybe. Amazing way to save myself waisted hours of my life, sweat and tears, and $ on trim and other supplies... definitely.
