Once long ago and faraway I bought dembart checkering tool company. I was never able to get Joe's sharpening machine to work in a satisfactory manner. So I defered to Dorian for that service but as time went on It got to expensive and I ran out of parts to repair the old tools. I still peck away at the idea of a air powered tool or an electric tool with a more modern type of dental tool drive. But at as I approach the down hill side of the 70's I just cannot gen up much interest.
THERE IS A GENTLEMAN IN TEXAS THAT HAS MMC TOOLS. I will try to find the contact number. I will post it in the next few days.
