I have converted a smaller and (I suspect) much lower quality one. In my case the bearing arrangement for the worm was rather less well engineered than I liked to use for a motorised axis (especially the thrust arrangement, which depended too much on carefully tightened grub screws) I ended up making a new inner housing for the worm, with an inboard needle roller near the worm, then an outboard pair of angular contact bearings. I then connected the servo with a rubber finger type coupling to fully isolate the motor bearings. (If your worm is properly straight this might prove to be less of an issue….) In your case I would probably investigate using a toothed belt drive to bring the servo alongside the table rather than sticking out a large distance as that would probably be limiting in the case of a 5th axis. -- atp "Torque wrenches are for the obedience of fools and the guidance of wise men" ------------------------------------------------------------------------------ Forrester recently released a report on the Return on Investment (ROI) of Google Apps.
