Thanks for the responses. I had a x axis power feed on my 1991 grizzly mill (dont remember the model) It had a plastic/nylon/synthetic gear that was driven by a metal worm, bronze, I believe. That plastic gear was sacrificial. I remember the machine jamming while I was talking on the phone. Tore up the plastic gear. Cost more for the shipping than the gear. 15 minutes after receiving the gear, the machine was back in operation. I may give the cordless drill a try. Where does one go to find an adapter? My mill (g0695) does not have a y power feed. Does anyone feel that a y power feed is all that usefull?Earl
