Thread: Bench Grinder Conversion

Ok so I've been using this for a little over a week now and it works well. It's not perfect, I have to start it a full rpm and then turn it down. I can only turn it down to about 60% speed because any lower and you tend to lose torque. I'm having no issues with the switch warming up ( I didn't really think I would it's a 600 watt switch) the motor is not getting warm either. I do stall it out when loading up the greaseless compound, but I think I would do that with any of these small 6" bench grinders that are only 3.4 amp.
So my conclusion is that it works and it's a cheap way of doing it. And always you get what you pay for.
$35 grinder
$3 switch
$2 out let
$2 box
Cord I had (burnt out the one end plugging in my diesel van)
