Greetings all; I gave up on that crashomatic box, and went out and found me one of those Dell 745's with an Intel dual core running at 2.6GHz, and 4Gigs of DDR-2. But I couldn't move that drive, no PATA connectors on the mainboard. So I had to install fresh, which went rather swimmingly,

I think the slowest headstock RPM is about 110 RPM. I think going down to 10 -20 RPM would be good. The gearbox on the headstock also has a lot of backlash. Driving it directly should fix that. Thanks Wallace. --

[Emc-users] Cylindrical grinder Jones and Shipman

2015-10-06 Thread Marshland Engineering
I've just purchased an old but good Jones and Shipman grinder. While stripping it all for sand blasting and repainting, it looks like a great candidate for CNCing. CNC the headstock rotation and the grinder forward/backward travel. See here (Not mine)
