Yes I what you do

actually, my SB9 uses one shim on each side of the headstock, so that was exactly what I was asking - can they each be a different thickness, and from the sound of it...yes. So I assume I can do the

Hi There, But you were taking the wrong point from the initial post.

Managed to get the stuck chuck off today. Gripped an offcut of 1 1/4" Whitworth hexagon in the chuck. Engaged the belt on the slowest non backgear speed, just to use the inertia to reduce shaft

That was the exact. Point I was stating

Hi There, There seems to be some misunderstanding about keeping the shim packs even. My reference is to bearings that use two shim packs on each bearing. Lathes like the Heavy Ten and larger use

wow

That reversing lever set up is one more reason I like the old wide bed Series O 9" lathes. It's just like the one (in design) used on the heavy 10. Roger

saw this today & moved it way up towards the top of my

If I didn’t live 4 hours away, this would already be in my truck :-D -Keith

If you have more wear on one bearing than, the other you can not shim them the same.I used to scrape spindle bearing in on large grinders and it would be nice to use the same shim but realistic.

Might be blasphemy, but aluminum cooking foil is about .001” thick. Steve Haskell

Hi There, 1) do you try to keep both the right and left shims at the same thickness? 2) How tight are the bolts supposed to be? 3) should the shims be the right thickness so you can torque down the

Thank you, hose pictures are a good start. I'd still like to hear from others who have done shim adjustments on SB9 lathes. Thanks, -Tom

In the files section there is a TechInfo folder and in that folder is another folder entitled Bearing Adjustment. that info should help. Good luck.

Hi, I noticed some odd behavior from my SBL 9" (circa 1957). I could visibly see stock in the chuck moving when the lathe was running. When I put an indicator on the chuck, and even on the end of the

It had to do with the material that the brushes were made out of. Higher load starting motors had higher copper content as opposed to the higher carbon contact of a generator brush that got

The bulletin printed by SB mentioned that starters don't get undercut but not why. Thanks for the additional info.

Thank you for the Bulletin. Printed, read and saved. Very helpful.

Hi, If memory serves me right you only undercut generator armatures not starer armatures, only those with carbon brushes not with copper brushes as starters have. Over the last 60 years I
