I acquired a nice but older Craftsman 12" bandsaw (113.24290), about 6-7" resaw capacity, but the motor and motor pulley are missing:(. What HP motor would you recommend? - I'm thinking maybe 1/2 or 3/4. And what SFPM speed should the blade be running?
I found this formula for SFPM - Motor RPM multiplied by the Motor pulley diameter divided by the Driven pulley diameter times the Bandsaw wheel diameter times pi (3.1416) divided by 12 = S.F.P.M. (I would assume the band saw wheel diameter is in inches because the formula divides by 12, thus giving feet per minute.)
