Mounting Brackets

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.

Adjustable Work Stop

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.

1", 2", 3" & larger vise widths available.

Note that 1" screwless vises differ & may or may not have built-in parallels

Work Holding Examples

Milling flats onto a Taig 3/4-16 threaded arbor for a 7/8" wrench
.


Not a screwless design but this excellent precision
Tool Maker's vise can also be used on small mills.
A very high-precision vise.


The Toolmaker's vise needs a pin spanner to fully tighten & loosen.


 A variable angle V-block used to make 45 deg beveled edges.


A 1-inch screwless vise with built-in, ground parallels, is being held at 30 deg by the 3-inch vise.
The built-in parallels aid holding especially small parts.   
Note that 1" screwless vises differ & may or may not have built-in parallels. 
The movable jaw of the small vise is not as wide as the base
so it can be operated while still clamped by another fixture.
Parts can thus be swapped-out while maintaining an accurate, fixed position.


Shown here, a computer keyboard key was CNC engraved
(white) so it will have a customized trans-illuminated label.

Parallel Sets

A set of 3-inch wide, precision ground parallels (import).

The shorter sets are ideal for smaller mills & vises.


4-
1/2" long, wavy parallel set (Swiss).
The spring steel can compress in the vise for very small pieces.
Use one slightly compressed parallel to support a narrow piece.
