I finally found a use for my little Dumore tool post grinder. I have had this unit for a long time, and finally got around to tearing the motor down to lubricate the bearings which were stuck due to dried grease, and to replace the cord. Replacing the cord is a long story for another time! Suffice it to say, it was a challenge.
I have never used the unit as a tool post grinder, nor do I intend to now. I just hate the idea of getting grit into all of the ways and bearings on either of my lathes! But I have found that it works very well as a TIG tungsten electrode grinder using cheap 1.5 or 2.0 dia diamond wheels available all over eBay for around a dollar or less a piece. I have also used it for grinding chip breakers onto lathe tools by judicious choice of 1/8 shank grinding wheels (Dremel, etc.) It works extremely well, no vibration, quiet, and has plenty of power in THIS application. Don't know how it would work as an actual tool post grinder, but I suspect it would be pretty weak. I don't intend to find out.
It works very well the way I have been using it, and I don't even have to take it out of its case - the grinding wheel extends to the outside, as seen in the picture. If some of you are worried about grinding thoriated tungsten, you can easily station a vacuum to suck up the debris before you can suck in any of it yourself.

Mike
