There are two types of rotary vices, balanced
and unbalanced. It is easy to tell the difference,
balance rotary vises do not keel-weight effect
because of the vise head clamp assembly. The
unbalanced rotary has to be controlled by hand
contact, to keep the shaft from spinning when
the vise head clamp assembly is at the apex on
the shank. The weight of the vise head clamp
assembly is the cause for this happening. Instead
of buying a new rotary vise that is balanced, I
decided to see how to make an unbalanced rotary
vise balanced (or as balanced as possible), by
counter-weighting the vise. I do not know what
brand your rotary vice is, but if your rotary is
similar to mine, I hope this article will help to
give you some ideas.
Loosen the Knurled Nuts (that secure the handle)
and rotate the handle 180 degrees so it is pointed up,
instead of pointing down, when in the resting position.
I went to the hardware store (taking the handle with
me), bought 15 metal flat washers, and 1 rubber grommet.
The washers will act as a counter-weight to the vise
head clamp assembly, and the rubber grommet is inserted
inside the outer washer to hold the washer (weights)
on the handle.
I have a balanced rotary vise, and only cost me $1.10
(state sales tax included). ~Parnelli
