Re: [CAD_CAM_EDM_DRO] CNC Conversion for Education

Darrell,

You may want to contact Roland Friestad at Cardinal Engineering. Roland did
a series if articles back about 1990 in the Home Shop Machinist on
converting mill and lathes. He is currently running a new series of article
in Home Shop Machinist.

I am in the process of converting an Enco mill for a local high school using
plans that I got from Roland. Roland will sell you a set of copies from the
articles that he ran back in 1990. This would be a great place to start.

For parts, I have been seeing a number of stepper motors on Ebay that may be
strong enough for a mill. The electronics is fairly straight forward using
Gecko drives.

If you need help with the electronics, I can furnish you with a set of
drawings that the students could use.
