F-Bird nailed it. Yes you can, but you'll be an old, old man before you get finished. Get on the Harbor Freight URL and order up an electric die grinder.

Yeah, yeah, yeah everybody says to use an air grinder, in which case you better order a two stage compressor as well cause those 2 cylinder single stage 5 horsepower jobs will melt down before you get finished. So just buy a high speed electric grinder and save the discovery about air grinders that nobody admits to.

Pick up a shop vac, good work light, face shield, and ear protection while you're shopping.

Trick if you're grinding on aluminum is to keep a bar of soap handy, run the cutter into every few minutes, that will go a long way toward keeping the aluminum from clogging the cutter whether it's a steel carbide or stone type.

If you haven't read David Vizards book on Chevy heads, get a copy of How to Build & Modify Chevrolet Small-Block V-8 Cylinder Heads . He goes into details of what and what not to do. While aimed at the Chevy head, it applies to any two valve wedge head.

You can get a cheap electric rotary die grinder from Big Lots for around $15. They're not exceptionally strong, but will work fine if you don't lay into the workpiece/grinding stone too hard. I have one that I use frequently for various small jobs and it serves it's purpose well. Doesn't have quite the power of a real die/mold grinder using compressed air-but still gets the job done if used properly. -Jim
