I got the plans a while back as I was thinking of making one for the Bridgeport I converted to CNC. I think it could be done as really the only bit of the R8 that is tapered is small. Some modification of R8 holders and there would be plenty of room above to make the stud puller. Also looked at the spindle on my mill and I reckoned there was enough meat in there to bore it out if more room was needed. In the end I got a Series 1 CNC with the QC30 spindle so it would not be so easy to modify it as the spindle is solid. I seem to remember that he was planning on selling the tool fingers but as I would have needed different ones I didnt look into that.
