    The issue with this technique is not that the pedal power isn’t effective, it’s that his ratio is not good.

    He needs to gear it up so that one revolution of his wheel is multiple strokes… he could also store the energy in a flywheel for greater cutting ability. Put the saw on a rod and institute a method to drop the blade onto the work once the flywheel is going and doing 60 strokes a minute and watch the blade cut the metal like a scrollsaw.

    Pedal powered lathes, scrollsaws, bandsaws, etc were quite common before the advent of steam or electric power.
