A couple weeks ago it became necessary to replace the spindle bearings in my Jet 1642 after about 8 years of use. I searched for some good DIY information and found very little. Having a background in machine work and being pretty mechanically inclined I tackled the job. It wasn't really difficult. I did do a two part video on the process and I am goimg to post a link in this post. Maybe it will be helpful. The process works with other lathes not just the Jet. It is what I did and how it worked for me, so I just hope it helps.
