Re: Aluminum Valve Cover Question
ptim,
I have used a 3/8" drill for polishing pieces that you can't get under a pedestal mounted buffer. A bench grinder probably won't be strong enough unless your bench grinder is using 8" grinding wheels. I use 4" or smaller wheels on my drill and have had good success. By the time you buy a pedestal, shaft extensions and wheels for your bench grinder you are almost to the place where it's less expensive to buy an 8" or 10" buffer!
