One more DAREX M3 question.

[paul]

I found instructions for the M3. I cannot find in the instructions anything that indicates the best spindle speed for the Grinder using a 6” wheel.

The unit Darex shipped with the M series was a common 3350rpm 6" bench grinder, looked just like dozens of other bench grinders -- (probabably was, just with Darex gold paint!)
