Re: [CAD_CAM_EDM_DRO] Asian Import mills, EMCO, PRAZI, Myford, MOTORS

Hi Doug,

Thanks for the thoughts. Yeah, I've got a couple of old Chevy's. I may
not want is a car made in Taiwan or China. I don't think I'll "ware
out" a mill, and if accuracy is not a problem, I can live with
handwheels coming off. Hay, I'll probably take them off anyway!

FlashCut had a Grizzly (I think) at a tool show in Santa Clara, last
year. It's not on their web site.

What is it on the motors? The 16" ENCO has a 2HP motor. Do I need all
that? Are the import motors not up to 2HP?

P.S. Anyone wanna trade a '84 Z28 Camaro for a GOOD mill?
