1 forum posts	Hi need some help with a myford lathe that my father in law has had for a good while can't seem to get the reverse traverse to engage or work?? We are looking to sell as it hasn't been used for a good while as it was handed down from someone else after we have solved the problem we are looking to sell any help would be great thanks!!!

If it will run one way then the gear train must be engaged properly (or it wouldn't), so any engagement problem must be with the second tumbler gear, assuming it is present. Also assuming the half-nuts are properly engaged every time. This extract from the manual may help. Edited By Robbo on 22/07/2014 11:20:46 Edited By Robbo on 22/07/2014 11:22:51
