I'm considering buying a bench grinder.
Now, I realize that there are variable speed grinders (or at least delta
makes one) on the market.
Is a variable speed unit necessary? or would a heavy duty one speed grinder
be a good option as well? Also, What are the pros and cons to having a six
or eight inch wheel?
One of the main things I'll be using it for is sharpening tools. Also, for
fabrication work and whatever else I can think of.

Thanks,

Michael
