I’ve been trying to do a large scale polishing job and need a little help. By the way, I’m a total newb at this. I’m attempting to polish the surface of one of those OLD OLD C-band satellite dishes. It’s probably 10 feet across. I was lucky enough to come across one made of stainless steel (probably 304??).

I started with some 8" wheels on a 7.5" Central Machinery angle grinder from Harbor Freight. I didn’t want to drop a load on a grinder if it wasn’t gonna work. First grinder quit working within 10-30 seconds. Not good. I got it replaced and the grinder seemed to work fine, but kept popping the breaker when I put a load on it. After a lot of very aggravating trouble shooting, I fixed that problem with a shorter, heavier gauge extension cord, and a rewired, dedicated 30 amp outlet. Success!!!, I was just starting to get a good shine on in a small area, when the angle grinder burnt out both brushes and quit working. I replaced the brushes and gave the grinder to a friend. Kinda tells you something when a new grinder comes with replacement brushes, huh?

Anyway.

What now??? I need a motor that can handle the heavy polishing load without melting down in my hands. Would a name brand, (dewalt or milwaukee) grinder hold up to the strain, or would I be wasting more money? Should I be looking at some other type of motor? I could really use some guidance here!
