Guys, I have always wanted a grinder so I could resurect some of my end mills but grinders are usually too costly to be viable for a hobby guy like me. I have been pondering this dilemma for a while and the other day a bulb briefly flickered on in my brain. (dangerous , I know). A while ago I acquired an old Black and Decker Super Valve Service valve grinding machine. It runs, but it is missing a few pieces like the valve holder for grinding the end of the valve stem. Both stones are there as well as everything for refacing the valve. Before asking the big question, realize that I have not put a great deal of thought into this yet as I have alot going on right now, but,has anyone tried to adapt a valve grinder to grind end mill cutters? I am thinking only the end and not the side. What do you think? : doable ? stupid idea ? not worth the effort ? By the way I'm recently retired so would have some time for this in the future.
