I just acquired one of these in good shape and am getting it set up. It has
a hefty-looking 4-spur drive center in it right now, but came with 4 great
faceplates of varying sizes.
My problem is I can't figure out how one would remove the drive center. The
outboard end of the shaft has a long nut going into the [threaded] shaft,
but this just comes out and nothing happens. Similarly there are two small
set screws with allen heads outboard on the side of the shaft, but removal
of these accomplishes nothing either... The thread on the outboard end of
the shaft is smaller than the thread on the face plates.
The spur drive center has a large (1 1/8?) hex head but there is nothing to
There should be a stopped hole just to the left of the base of the
4-spur drive center. Insert the end of a shaft or bolt in it and use it
as a lever. Apply an open end wrench to the spur center itself. The spur
center will screw off toward you.
I think they used to have a special wrench that would fit in the hole at
the shaft, so maybe look around the pile of loose parts that you may
have picked up with the lathe.
Nice lathe, IMO.

I think J is probably right. A very few of the older lathes used
solid spindles and screwed on drive spurs and accessories. I saw an
old Walker Turner where this was the case, and the owner of the lathe
mistook the hollow end where the handwheel was mounted as a sign of a
totally hollow spindle shaft.
He beat the absolute hell out of that thing trying to drive out the
spur thinking it was a taper fit of some kind. Of course it never
moved. Being old iron he didn't hurt it, but he didn't get the spur
out either. He took the headstock to his buddy in the welding
profession who took it for granted that the spur screwed on because
that was the way his accessories mounted on his metal lathe.
He took it off exactly as J. described.
BTW, I had to do the same exact thing to a 30 year old Sears lathe
about 2-3 years ago. Liquid Wrench, a 12" pipe wrench and a 12"
crescent broke it loose.
You were right, J. A couple of strategic applications of WD 40, a couple of
hours of patience, a pipe wrench outboard and presto. (There was no stopped

I'm actually quite happy with this unit. It has an extension to the bed so I
can take up to 52 inches in length.
My old Rockwell/Delta is a bit younger than your Beaver but it's
essentially the same lathe. (I guess the stopped hole was a later
improvement.) With the bed extension on you're probably going to need or
want a steady rest. And if you ever decide to get a scroll chuck for it
you'll find that the Nova series is the only one around that has a
7/8-14tpi headstock spindle adapter. (I believe it is highly likely that
your inboard thread size is the same as my later model.)

Hoping you look at your owners' manual. CW is speaking from below the

IIRC, there are flats on
the spindle to keep it from rotating as you unscrew. It will be a
right-hand thread, so Leftie will get Lucy. The one in the picture
here shows threads and
the locking setscrews on the other end.
