I tend to lurk on this sub-forum, and I have seen lots of interesting information about spindle repair. I hope it is within the spirit of the thing to call attention to a brand new (Jan.19) video on YouTube made by Robin Renzetti about spindle bearings. It runs 1.5 hours but does not feel like it! He covers the selection and fitting of new bearings in a Trak mill, including his ways and means of fine-tuning spacers and the like. I suspect there will be something for everyone.
