I'll bet there may have been some chips there. the pin was
binding in the vise body, so I had great difficulty separating
the two, and they've never been together again.
Hmm ... if the pin was binding, perhaps the vise body did not
set down far enough -- held up by the pin, and thus pulling up part of
the swivel ring.
6) And -- which I should have put as the first item, the alignment
keys in the bottom of the main vise body should be removed, and
replaced on the bottom of the swivel base -- or just set aside.
If they are left on the main vise body, they may hold the vise
a bit clear of the swivel base and thus allow it to rock.
The keys hang way out beyond the swivel, so they can't interfere.
O.K.

I've had good results with a swivel base on both a 4" Kurt clone
and a 3" Kurt clone -- with rather heavy cuts in a horizontal spindle
milling machine.
This is the 6" model, and I wish I had a bigger one, but I
wouldn't want to lift it. Anyway, now that I have CNC, I don't
NEED the swivel anymore, so I don't care what the problem was.
The horizontal is a small one a Nichols, and the swivel base for
the 4" Kurt clone projects far enough off the edge of the table to limit
the Y-travel. With the vise alone, there is no problem. There is only
one T-slot in the table, so there is no option to mount the swivel base
in a different T-slot to avoid the intereference.
The 3" clone fits with no interference, so it was what I used
until I got a genuine Nichols milling vise which is closer to 5" grip
and on a swivel, but with no interference. Also -- the swivel base has
a vernier scale to allow angle setting to 15 minutes IIRC. The Kurt
clone does not even zero properly. :-)
I do have a 6" genuine Kurt (those are more affordable than the
smaller ones), but no swivel base for it, because that machine was a CNC
machine, too.
Enjoy,
DoN.
