A 3-inch, screwless vise for the
Taig mill. The
original milling
vise is not good enough for precision work.
A good vise to use on the mill is this
precision screwless type. This type of vise has very flat (± 0.0002") &
parallel
critical surfaces. It is also, of course, hardened. The movable jaw pulls down as clamping pressure
increases so the part does not rise. The precision surfaces eliminate/minimize part
marring. Typically,
a
drill press vise does not have the precision or features
required for milling.
Can be used in conjunction
with a miniature
screwless vise.
Screwless vise exploded diagram
3-inch vise; adjustable, pivoting, solid-jaw mounted work
stop. An M6-1 cap head screw holds the bracket.
The adjustable 8-32 screw has a pressed-on knob, a tip that was diamond ground
flat, & a knurled lock nut.
Of course, the stop can be pivoted out of the way, placed on
the other side, or simply removed.
Work Holding Examples
Milling flats for a
⅞" wrench onto Taig ¾-16 threaded
arbor.
Not a screwless design but this excellent precision Tool Maker's
vise can also be used on small mills.
The Toolmaker's vise needs a pin spanner to fully tighten &
loosen.
A variable angle V-block used to make 45º beveled edges.
The 1-inch screwless vise, with built-in ground parallels, is being
held at 30° by the 3-inch
vise.
A computer keyboard key was CNC engraved so it will have a
trans-illuminated label.

comparisons.
Parallel Sets
A set of 3-inch wide, precision ground
parallels (import). The shorter sets are ideal for smaller mills & vises.
4½" long, wavy parallel set (Swiss). Spring steel can compress in the vise for very thin pieces.
