Ok. sa-motorsports.com said that a 10,000 to 12,000 rpm grinder is necessary.

Any of you guys running an electric grinder, and some how slowed the RPM's?

I found some die grinder's on ebay with a speed setting changer; only problem now, it doesn't support the 1/4 colett. can't I just get away with putting on a different colett's on any die grinder?
