Clone 4" Kurt-style Mill Vise Acquired - Update 2
Joseph Gwinn
February 2010.
I noticed that when I tightened the new swivel clamp bolts (that are standard
1/2-13 T-slot bolts with spherical washers and heavy hex nuts), the vice still
shifted slightly. The cause is that the tops of the cast bosses against which
the washers bear is not parallel to the table surface, so there is some sidewise
force when tightening.
Well, there is lots of meat there, so I clamped the vice to the table and milled
the tops of the bosses off parallel to the table. Took maybe 1/16" of material
off.
No more motion when tightening.
I also trimmed the T-slot bolts off to length, mainly for appearance, and to
keep the ends out of the way.
The crank handle that comes with the vice is big and heavy and clumsy. A used
6-point 15mm deep impact socket and a small breaker bar works far better. The
reason to use a 6-point deep socket is that it will stay on the vice until
intentionally removed, and not that great torque is needed.
Step by step, I am re-inventing Kurt.

My answer to the Kurt handle question. The hub used to be a deep
socket.

That's a very impressive handle for a Kurt, but don't you think it is really

Maybe a very small ship, or one of those boats that are towed around a
tank at Salem Willows. <g> Lobster fishermen do like small wheels on
their hydraulic steering, but prefer the type with six handles around
the OD.
I was in the marine hardware business at one time and our wheels were
considered superior because, being cast from manganese bronze, they
weren't as likely to bend as the competition's naval bronze wheels.
This seems like a minor point until your foot is tangled up in the
warp of a pot that's going overboard and the wheel is what you happen
to be holding onto.

Nice if you have the room.

the middle a hex hole and the other end is a handle.
The bone is 1/2" Al as is the handle.
It fits on my large kurt vise and works to snug up stuff.
I have a big wrench if I want to make it tight.
