I have a Delta wood-cutting bandsaw that I wanted to modify to cut both metal and wood. At the same time, I reduced the base size to take up less floor space:

Cant quite tell in pix, but is the second motor (the original?) mounted so that you can do a belt change and regain the original speed/sfpm?

I always wondered why they stuck the motor back there anyway, what with that room underneath....

So, How did the gear motors speed work out, did it hit on a good sfpm for doing metal?

Nice job. I did a similar mod to mine - I installed a 1/4 hp gearmotor onto the lower shelf and used a chain drive due to the higher torque. I removed the driven sheave and replaced it with a sprocket. I kept the stock motor intact, but added a two way switch so I can control either motor separately. If I need to cut wood, I remove the driven sprocket and reinstall the driven pulley and belt.

Yes, the motors are positioned so I can swing the belt to either one. The tensioner moves to the other side.

The slow motor gives around 170 sfpm. I may instal a VFD, switchable to both motors, to get more control.

Here is my take on the same. It has two speed ranges plus a VFD.
