I've just bought a new lathe that has a few issues.
1. The tail stock hits the inside of the saddle lifting it off the way. I've
spoken to the guy at the shop and he wants to just swap the tail stock with
one off the demo lathe he has. Will this be ok or are the tail stocks fitted
to each lathe?
2. The change gears are misaligned. The smallest gear is 10 mm thick, the
gear it drives it 8.3 mm thick. They are offset by 2.8 mm, is this normal or
should I pack the small gear out 2.8 mm?

any links on setting up lathes for noobs appreciated

Thanks in advance
