Finding small hardware for a SB 9 B lathe

[JoeJoe62]

I am new to PM and a newbie to restoring SB lathes. I took on a restoration project of a 1944 model of a SB 9B lathe. I have followed the process outlined in "A Guide to Renovating the South Bend Lather 9" Model A, B, &C." I have also purchased "South Bend Lathes Parts List For 9" Lathes." I have some missing parts such as a screw, spring and shoe in the right side of headstock that is inserted on an underside of the bearing supporting the eccentric bushing (Part No. PT376NR1, PT376NR1, and PT1075NR1). Also, I am missing the stop screw and nut on the opposite end of the headstock under the bushing supporting the eccentric shaft (Part Nos. PT377NR1 and PT1058NR1). I am also missing the screw and washer that closes the oil access point for the back gear assembly shaft (Part Nos. PT1151N1 and PT378NK1). Finally, I do not have any of the 17 change gears. I have been searching Ebay for these parts without luck. I do not want to buy and entire headstock to get these parts. Can anyone help on how to find these parts? I have had fun and frustration in the restoration process. I was never able to remove the taper pin of the handwheel on the apron )Step 37 of the SB Guide). I used a brass punch of the proper size but no dice. It wouldn't budge. I also found it impossible to remove the transverse gear shaft (Step 40 of the SB Guide) even using a heavy duty arbor press. I also made the mistake of getting a little bit of paint in some of the threaded holes on the headstock. I had to use paint remover and a dental pick to remove most of the paint and then used a tap to finalize the cleaning. The tapping process was very satisfying when the corresponding bolt glided into the newly tapped hole. Can you tell I am new to this hobby? Any help you can give me would be appreciated for finding the small hardware and the change gear set.

I have found these gears but am not sure if they would fit my 1944 model 9B lathe. Can someone identify them? Thanks.

Welcome JoJo!

I suggest you check out James Clough's Electronic Leadscrew on YouTube at <Lathe Electronic Leadscrew Part 1: Proof of Concept - YouTube>.

Perfect way to eliminate change gears!

Thanks, I will do so.

If you want a more turn key option look at the Germans Rocketronics - Produkte fur CNC und Automatisierung

I’m in the same boat house with my 10k model c you will have fun and be frustrated at the same time but I’m enjoying learning about these machines I’m in the painting and finding part stage.
