Just Acquired a SB 9A. Questions.

Question. The orange motor drive belt is shredding away at the edges. I think it may be too large for the motor pulley; but not sure. It is an interesting set up in that the belt is a "V" belt and the counterbalance pulley is flat while the motor pulley is a V. Should I just use the belt as is so I can try some turning, or should I get a new V belt. Other options and comments welcome. Here are some photos.

I'd get a new belt, they're not expensive. Gates AX (1/2" wide) V-belts are really nice and wrap well around small pulleys.

Another question. The serial # is 113591 JFP. Could not find anything in my search with the letters JFP. Anyone know what the approximate date might be?

Can you post a picture of the serial number?

I think you can call SB and they can help you with this....used to be able to anyway.

That looks just like -my- first lathe! It's a great machine!

You need to plan to make one of these for when the "oh, #$%! My chuck is stuck!" Moment arrives... a 3D printed one would almost certainly work. Mine was hand filed and semi-broached off my spare/broken back gear.

I'm also voting for "swap the spindle felts". I wish I had done it earlier! Pulling the spindle isn't all that difficult. The hard part is finding the courage to do it! You can pump oil into those felt holding holes if you want to flush things a bit. It won't clear the sump, though. 100% chance your felts are hard and crudded up if they haven't ever been changed (like mine)...

And clean, clean, clean the spindle threads (inside and outside)!

If you go to www.wswells.com you can look at the serial number database and narrow down the year of manufacture.

That's an interesting idea. Do you have a picture of where that mounts?

Looks to be 1941

Whoops @ShagDog I transposed your serial number as 113951 instead of 113591.
No matter really as it still looks to be a 1941.
