1938 15" SB Rebuild Progressing

[atwatterkent]

Finally got back to the 15" rebuild. After finishing the QCGB rebuild we reinstalled it and the lead screw. I remachined the 14 1/2" SB half nuts, which were missing, so the lockout rod functions. It was a different design considering it's a series N model. The lathe doesn't have auto cross feed. The lockout knob pushes in & out to allow for longitudinal feed or half nut threading. After cleaning the carriage I reinstalled the apron, saddle and compound. Next comes the tailstock.

Lot's of nice work there and thanks for posting.
I've seen the lever arm and weight used before while penetrating oil had a chance to soak in.
Next morning one of the guys walked over for a look and just rested his arm on the lever.
The joint broke free and the arm came down damaging the surface below.
Nothing like hindsight!!!

The one thing I really wanted on a lathe I was looking for was the carriage T-slots...your very lucky! I havent seen many larger SB's with carriage T-slots. You never know in the future if you need to line bore something.

I was thinking along the same lines. I am envious of the lathes with T-slots on them and wish I had them on my 14 1/2 ....
