Here you get plans for a 60 strokes-per-minute hacksaw machine powered by a 1/3 hp 1725 rpm electric motor. The saw uses a 14 tpi blade and will cut through 1/4 x 3” flat bar in a couple of minutes, yet weighs little more than 50 pounds. The final drive speed is reduced to 60 rpm using standard belts and pulleys. Plans for a heavy duty, adjustable angle vise are also included.
