band saw speed for metal?

rheostat to control speed?
I have a "table" that mounts a hand held band saw...just need the band saw. The table comes from a Jeep enthusiast out west.
no, wont work as its an A/C induction motor. 3 phase can be changed, single phase not so much without killing torque. changing it to DC would work but finding a beefy 1HP DC motor would be $$$ as well as the inverter needed to run it. treadmill motor/Newer washing machine motor with its speed control would be awesome.
