Chris, I am surprised that you had to use *so*  much force to remove/
	install the spindle. 
	
I was too. But I'm pretty convinced that the force was all about getting
the Woodruff key seated into the bull gear.

We'll see. I haven't spent much time at the highest speed, but it seems
to be working well at all the others.

(How do people lube the back gear, by the way? Are there zerk fittings
out there with 1/4-20 threads, to pump the Teflon grease in?)

  They do make a 1/4-20 grease zert. We have a box of them at the shop. We
got ours from the local NAPA auto parts but you should be able to find
them at any good hardware or parts store.

Quality is like buying oats,
        if you want nice, clean, fresh oats you must pay a fair price.

However, 
        if you can be satisfied with oats that have already been through
the horse...
                          
That comes a little cheaper...

There is a little hole near each end of the backgear shaft
mount in the headstock.  I put a couple of drops of oil in
there.  There is also a screw in the middle of the backgear
shaft housing behind the drive pully, almost i line with the
oil screw in the steped pulley on the head stock.  On my
lathe it has a gasket on it, so I remove it  and I fill it
up with oil.  It goes around so you may have to look for it
- easy to find by turiing the thing with the back gear
disengaged.  

There are a lot of unlabeled oil holes on the SB, especially
in gear train leading to the lead screw.

By the way, you you know the pitch and presssure angle of
the change gears on a SB?

That's the hole I meant, along with the one in the drive pully on the
spindle. The current recommendation from SBL is to use Teflon grease,
and I was wondering about the best way to introduce same.

However ... I have a lathe, so I can make an adapter!

I called my local NAPA auto parts store, used the phone, the thing without a 
keyboard :-) They said they did not have them, and their book did not list the 
1/4-20. Must be a different level of store...

I also checked McMaster Carr, my local ACE hardware, no luck so far.

  I will see what I can do about liberating some. I havn't looked very
much though I did notice them in a kit sold by MSC when you first asked
about them. I will have to double check but I could of sworn that they are
1/4 20s. Let me know where to send them and we can work things out. 

 Lets see....., Oh I guess they shouldn't be worth more than there weight
in gold. Whats gold going for now days. :-)
