Converting wood bandsaw to cut metal.
I have this old bandsaw that I picked up for next to nothing, it had a broken mount for the upper wheel.
I was able to buy a replacement mount, but while a wood bandsaw is nice I really needed one that would cut steel. This bandsaw had a multiple belt reduction already but it was not slow enough to cut steel.
I switched it to a 3-phase motor and added a VFD. The VFD not only allows me to run it 3-phase from single phase but also allows speed control from zero to what ever your motor will allow. Mine works from 0 to 120Hz, so I can run it faster than usual or slow enough to cut metal, all without changing the belt.
