I recently purchased a SB lathe that was manufactured as a '9C' and then upgraded at some point to a '9B'. It appears to be 1933-ish vintage based on the serial number and I ordered a serial number record from SB.
My question is - I noticed that the nut holding the stud gear was missing and then noticed that the stud gear is only half meshed with the mating gear on the banjo. By 'half meshed' I mean that the planar alignment of the gears is not complete. Judging by the location of the journal for the stud gear, it never would fully engage the mating gear. While the loads on these gears is not tremendous, it seems odd. Am I missing something here or is this just the way it was designed for some reason?
Thanks!
