Is there a good primer for a beginner? I have an Index 40h that I am interested in retrofitting with computer control. I don't see anything about this mill, is there a something (common) that is similar? It is what I would call a "3/4 knee mill", in that it is maybe 3/4 the size of a series 1 bridgeport. Has anyone converted this mill to CNC? What forum should I watch? Thanks.
