I don't know, man, but if you're into woodworking and making jigs and whatnot, then you probably already process the skills and mental fortitude to get one of these things all trued up. I spent a good day taking mine apart, cleaning and greasing the parts, putting the new (recall) parts on and getting everything square, parallel, and true. After that it was in better shape than new. Of course, I enjoy doing that kind of thing while listening to music or a game and having a beer or two. Beats watching reality TV. :-)
