If the quill doesn't project below the head casting when all the way up, and there's no slot like on Bridgeports and clones to attach a ballscrew nut to, there's still a way to add CNC control. Replace the spindle retainer nut with a custom made plate that has a projection down and out to one side to connect the drive. To have the thread rotated correctly in relation to the drive attachment isn't difficult. Make the new nut/plate oversize and screw it into the quill, then mark where the drive attachment will mount, cut away the rest of the excess material. An alternate way would be to make the nut thicker so that a clamp style mount can be used, like how DRO mounts are often fitted to drill presses and drill/mills. ------------------------------------------------------------------------------ Managing the Performance of Cloud-Based Applications Take advantage of what the Cloud has to offer - Avoid Common Pitfalls.
