For those of you with disk grinders. What are you using? I'm looking at the 1 horse 9" from tru-grit. Thanks
From what I understand the Harbor Freight Disc sander is not a bad unit? You can get single phase VFD and make that variable
a phase converter/VFD changes single phase 110 to 3 phase 240. I have 8" and 6" discs that mount on VFD controlled motors. 8" and 6" are widely used commercially so there are many PSA(self adhesive) discs and disc heads to choose from. if you already have a VFD to supply 3 phase, just get a footed motor and a disc head. I mounted mine on the side of the bench. you can leave it at that or spend more for adjustable work surface. my porter-cable 4x36 has an 8" disc, but the speed is way to high for steel.Ok, thanks. I haven't looked into phase converters in quite a while. So the vfd on the grinder converts it to single phase 110 volts?
