I've used a belt sander to change the soles on running shoes and am looking to move to a bench grinder instead.
Harbor Freight has one for $40 that looks good, and it comes with a 60 grit wheel.
I'm thinking a 24 grit would be better but 60 was the smallest they have.
Does anyone have suggestions for the kind of bench grinder to get?
What grit wheel did you use and how did it work on the rubber?
