Anyone have ideas as to what to replace my grinder with? The low speed,
(70 to 400) wet, looks like a good idea. Comments welcome.

Take a look at the 8" grinder offered by Woodcraft. It runs at 1750 rpm and
sells for under $100. The ability to sharpen your tools properly is one of
the most important phases of woodturning. Either learn to do it properly by
hand or get a jig like the Oneway Wolverine. I don't think you will regret
it.

Hope this helps.
