So Far I have made a pinion gear for the apron, the half nut, crossfeed nut, retrofitted a grizzly g0709 compound, new gibs for both and now ....I noticed a severe amount of backlash on the tail stock but really thought nothing on it. Well after finishing the crossfeed nut I decided to take the tail stock apart .... this is what I found. The collar around the nut is completed fractured around the circumference. I tig welded it with some silicone bronze until I get the 5/8-10 tap ..... never stops
