Re: [CAD_CAM_EDM_DRO] Re: New Mini mill/drill

Fogassa,

Thanks for the info. Checked out your web site, looks good. If I
proceed with this machine it would be my fourth CNC. The previous were
totally home made. I noticed your idea to make parts for others.
Perhaps after I finnish this machine we could compare notes on the
conversions. I don't have any interest in making commercial parts, but
it would be nice to share information that would help others.
