Hi and thanks for the support. I have a set of forged aluminum wheels that I would like to polish. I've read through the "read this first" part of the site and still have a few questions. Since I live in a small townhouse and I really anticipate polishing only these wheels, so did not want to purchase a bench mounted grinder/polisher.
I was originally going to use one of those electric hand sanders (the one that uses like 1/3 sheet of sandpaper) and work my way up to 100-200-400-600-800 grit (wet sand for the last two grits).
For the buffing and polishing part, I had purchased a no load sander/polisher from Harbor Freight that is supposed to spin a 2600/3300 rpm. Pretty much this one

But I am not sure how buffing/polishing wheels are suppose to fit on there. It came with a 7" head for the polishing bonnet (kind of like a shower cap).
Then I was going to use an electric hand drill, because I've seen the buffing wheels made for hand drill, but could not find one that seemed to be able to spin enough rpm (as recommended here). The fastest I've seen spins at 3000 rpm.
So, then I was thinking about an angle grinder with the adapter piece sold here. But the ones I've seen online spin about 10,000 rpm or more. Will that be too fast? I was thinking about using the grinder to sand the wheels down, but couldn't find the appropriate grit (listed above) to do the job. Do they make wheels for an angle grinder is those grits?
So, what would you use? The sander/polisher, the 3000 rpm drill or an angle grinder? I can pick either one up at the local Harbor Freight store. The next thing is, I'm not really sure which buffing/polishing wheels to purchase. I can figure out the sissal wheel/cotton wheel part (I think), but my question is more along the lines of "do I need a different wheel if mounted on a drill versus sander/polisher versus to an angle grinder?" and then how do they mount on it?
So, basically the question are:
Thanks again, tons of simple questions. More to come, I'm sure.
