Mark , It's really not a big deal to pull the spindle .
You should make sure that you have new felts for a machine that
sat that long . You can get the felts in a set for the whole lathe
& then some & a book that walks you
through the process . You will be glad you , alot cheaper
than buying a new spindle & headstock

My father bought this South Bend 9C, possibly new or with some
demo deal (as he had almost no money at the time), around 1940. I
purchased the serial card from Grizzly, and it all matches up
except, oddly, the length of the bed (the card says 3', but it's
actually 3-1/2'); since the serial number is on the bed, it's hard
to understand that mismatch.
Regardless, he used it for a while, then while I was growing up
we'd make a few projects with me "helping" (I was around 10 to 15
at the time). He died, far too young at 55, in 1980, and the
lathe had a tarp thrown over it. There it sat at my mother's
house until she died about a year ago (at 96). I cleaned out her
house, and put it in a storage unit for the next year. The unit
was fairly near the waterfront in the San Francisco bay area, but
when I stored it I drenched everything with BoeShield. Now I've
moved it up to my new (heated, dehumidified) shop in Oregon, and
one of my first retirement projects is to get it working again.
Amazingly, there is essentially no rust anywhere. The exposed
iron and steel has darkened a bit, but appears to be in good
shape. Because I know its entire history, I'm certain that it
wasn't mechanically mistreated, so it shouldn't be too difficult
to bring back to life. I've mounted the lathe and motor on a new
table, and replaced the leather drive belt with a new one - the
V-belt, although aged, still appears to be usable. But there
seems to be a problem...
The main spindle won't turn. If I disengage the back gears and
pull the locking pin, the cone pulley spins fairly freely, but
I've been unable to get the spindle to move. I also disengaged
the change gear reversing gears, to no effect - it's the spindle
itself that's really locked up solidly. I feel as though it must
just be dried lubricant on the bearings, because it was working
when stored, but if so it's a lot more locked-up than I would have
expected. I tried mounting a 10-inch faceplate, and even with
that I couldn't apply enough torque to break it free (I may be
retired, but I'm not too feeble yet...). I stopped short of
putting a pipe wrench on it, but just barely...
Any other ideas about what I should try, before breaking down and
disassembling the whole thing (which I've been trying to avoid)?
And once I get it moving, any recommendations for chemicals and
methods to clean off the 50 years of crud? I already have a
rebuild kit (felts and such-like) and a kit of oils, but I'd like
to get it cleaned up first.
