Ok here's some shots which show what's going on with my leadscrew
above is the gearbox! the vacant hole is what the leadscrew goes through and the offending face can be seen. The one surface is shared with the mating gear meaning the outside diameter of the gear can touch the face around the point it mates with the other gear.
so this is the face of the gear. There's the odd bur and nastiness on the face of the gear teeth that goes against the gearbox casting. That's the source of my problems. I'll mount the gear in the lathe, cut the diameter that is contact with the face down smaller and reface it. More on that later.
These are the locknuts that hold that gear on the leadscrew. They have the odd dag as well, which can't help. I've cleaned them up with a file and deburring tool.
Anyways I pulled the apron off while I had the leadscrew out
I've had this lathe for 26 years and never pulled the apron off, so was expecting alot of crap to be in there. It wasn't so bad.
Anyway I cleaned the apron up. It's all good on that front now.
Then finally another detour
while I've got things apart I decided I should machine the back of the saddle so that I can use this taper attachment that I've got.
That's it for now
