Jim , yes challenge is good to a point . The machine that I was describing was a 85' Super Max knee mill that was designed to accept a CNC package by any company that wanted to buy it and install there own stuff . The Super Max was a good machine with the Anilam controller , it could switch from CNC to manual and that made set up and prototypes doable within a decent amount of time . The machine as a stand alone manual machine would have been limited , first you could only tram the head in the X axis , Y was fixed . There was no tilting the head to get a angle , yes Jim I know what a angle plate is . Rather than say there was no way to convert it , I should have said there was no sensible way to do it . Now how could it have been done ? Copy a Bridgeport , grind a gear rack in the spindle and get a pinion to work , there was no provision in the head for that , it would of had to be designed and machined , no thanks . A easier solution , get a Bridgeport head mounted on the ram , remember the head was basically fixed so a knuckle would of had to be designed and machined , again no thanks . Jim you seem to be in the retro fit game , that puts you in the commercial category not the hobby category you should be careful what you suggest around here you could lead someone down the path of a huge waste of time and money . So could it be done , ahem , yes . Should it be done ?
