Lindsay Publications has (or had, and probably still do) reprints of the SB book "How to Run a Lathe," which describes how to set up the change gears, among other things. Lindsay also has/had a reprint of a SB booklket, "Keep Your Lathe in Trim" or some such title, that describes how to adjust the bearings and things like that. Worth getting.
