INSTRUCTIONS
The advantages of this vise are obvious
when movement of the jaw is studied. (See
Figure 1 and look at the bottom of your
vice.) The tightening force (F1) produces
not only a force against the part (F2), but
also a force pulling the jaw downward
(F3). Therefore, angle “A” must exceed
45° in order to make force F3 greater than
F2. This keeps the movable jaw from
“tipping” back. Also note that extreme
clamping angles beyond 60° start to apply
much downward pressure but not much
horizontal force is directed to holding the
part. Moving the pull-down barrel to the
proper slot keeps the adjustment within
the most effective clamping range.
To clamp a part, place the jaw in approximate position and
start tightening the adjustment screw at an angle of 45° or
greater. (The back face of the moveable jaw is machined at
a 45° angle for reference.) If the angle of the adjustment
screw gets up to 60° or greater and you still haven't drawn
down on the part, loosen up the screw a little and move the
pull-down barrel to the next slot and retighten.
Figure 2 shows the proper way to hold a part in the vise. If
the part cannot be centered, use a spacer to help keep the
jaws parallel. This vise has been designed to accurately
hold objects being machined. It is not recommended for use
as a bench vise or for clamping parts in such a way and with
such force as to adversely affect its accuracy.

and slightly soften or deburr all the edges of the angle clamps that contact the table.
