Re: [CAD_CAM_EDM_DRO] Grizzly minimill

Ron Ginger has retrofitted the Grizzly to CNC and has pictures on his
site http://plsntcov.8m.com/grizzley.html . I also bought one a few weeks
back and am very happy, however I agree about the lead screw and setup
issues. All in all the Grissly is a smokin deal for the money.
