Lock the axes before aligning the fixed jaw of the vise.
Machinists
distinguish between indicating a part (alignment) vs. tramming (centering).
However, the
definition of
tramming is "to adjust or align (mechanical parts). Accurate mechanical
adjustment: The device is in tram."

Tool
Maker's Vise
Tool maker's vise: 2-9/16" (62mm) W
x 1-1/4" (32mm) D opens 3-3/8" (86mm) & OAL is 7-1/2" (190mm).
Hardened & precision ground to within 0.0002". Single-piece base construction.
Vertical & horizontal
grooves to hold round parts. Acme ISO TR16x4 threaded lead screw for speed & strength
(China).
All sides ground square.
The movable jaw has a counter bore
around the lead screw attachment point which provides
relief for the threaded bronze insert. This allows full jaw retraction for
maximum vise opening.
The jaws are very precisely aligned to each other.
The movable jaw is not quite as wide as the base so it can
be moved while still clamped in a setup.
Also handy for use as a transfer vise between setups. Shown here with the
5-axis work stop (right).
Its strength, speed, size, &
precision make it one of the best all-around vises I own.
This vise
is also very good for use on the
Taig mill.

Note that 1" screwless vises
differ & may or may not have built-in parallels.
The built-in parallels aid holding especially small parts.
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 a fixed
position.

allowed a 4th (6") bolt to be utilized.
Spring-loaded detent shown. There are two, base swivel locking lugs.
Attached my benches, at two points, to the cement wall for maximum stability.
Soft Jaws
Soft jaws made out of aluminum L-bracket.
The stick-on
magnetic backing was problematic.
OEM hardened, ground steel jaws (above)
& aluminum soft jaws (below). Original M6-1 cap-head
screws were reused. The jaw dimensions are 5-1/8"(L) x 1"(H) x
1/2" (D).
The aluminum soft jaws
were drilled for 5/16" clearance followed by an end
mill for a 1/2" counter bore to
0.310" depth.
A Columbian 4-1/2-inch (USA) bench vise.
Milled, smooth-finish, soft aluminum replacement jaws.
To remove sideways play in the slide bar, I drilled &
tapped (1/4-20) the vise body for a set screw
(other
side).
I put a small (3mm) length of Teflon rod in-between the
screw & slide bar to reduce friction.

Pin Vises
This pin vise stores drill bits in the handle (USA).
Very high quality with a precision chuck.
The chuck has a 1/4" (0.25" or 6.35mm) capacity.
Very handy when deburring especially
on a lathe part.

(0.0625" or 1.6mm) & 3/32" (0.09375 or 2.4mm) sizes.
Micro-chuck.
Hand Vises
Custom-made hand vise with an aluminum head & handle.
After reviewing the pros & cons of many different
designs available for purchase, I decided to make one
that incorporated the desired mechanical attributes.
This hand vise was specifically made to hold hardened pins
while
they are being diamond ground.
Both sides were fly cut.
The
jaws are opened & closed using a lead screw that has
both left- & right-handed 10-32 threads.
Using this type of lead screw moves the jaws at twice
the single-thread rate.
The non-threaded
center section of the screw has
clearance via short counter-bored holes.
The movable jaw is
guided by a 1/4" dowel pin riding in a
0.251" precision reamed hole.
The movable jaw has
a blind hole with a 6-32 set screw
that holds the pin as it slides through the fixed-jaw hole.
The
movable jaw's bottom surface also slides on the
fixed jaw which greatly reduces any twisting.
Jaw size: 1/2" W x 1" D x 3/4" opening. Aluminum jaws are fairly soft
so part marring is minimized.
The fixed jaw has two V-grooves to
clamp round parts. The knob was threaded 10-32 &
then a 6-32 set screw was installed. A 4-40 pan-head also
screws into the lead screw's end.
Shown for scale, a 1/4" x 2" dowel rod is clamped in the
larger V-groove.
The
9/16"
knurled
aluminum handle is attached using a hardened,
one-inch long 1/4-20 set screw.
The other end is tapped for 8-32 to hold another head.
This long-nose hand vise was made for
grinding delicate parts.
These jaws also open & close using a lead screw that has
both left- & right-handed
10-32 threads.
Using this type of lead screw moves the jaws at twice
the single-thread rate.
V-grooves were cut to hold small
round parts. Jaw size: 1/4" W x 2-3/4" D x 1-1/16" opening.
A
long 8-32 set screw holds the lower brass guide rod & the
handle. A 4-40 set screw holds the upper guide.
The brass rods slide in precision reamed 1/8" holes. A
4-40 pan-head screw at the end of the lead screw
limits the overall travel. The knurled brass thumb
adjustment knob is held by two, 6-32 set screws.
The same knurled handle is used for
both vise heads: 8-32 left & 1/4-20 right.
Two
different styles of drop-forged
hand vises (Germany). Acme thread used for extra strength.
Narrow spring-loaded jaws: 1/2" W x 1" D x 3/4" opened. 3-3/4" OAL.
Excellent design & high quality.
Wide
spring-loaded jaws: 1-3/8" W x 5/8" D x 1" opened. 4" OAL.
It has a
V-groove for holding round parts.
Exploded views of the two hand
vises.
A hand vise designed to
clamp long wire (Germany).
The tightening
screw & handle have clearance holes.
Jaws: 5/8" W x 1/2" D x 1/4" opened. 4-5/8" OAL.
Replaced the original wing nut with a
higher quality part. Replaced the steel washer with a
brass type.
Made a washer out of oil-impregnated
bronze to ease operation of the (tight) wing nut.
A ball
bearing thrust washer works well, too.
Lowell
Pattern hand vise (wire-working tool) with hollow
handle (Pakistan). Moderate quality.
Overall length is 4-15/16" (125mm).
Handle diameter is 3/4" (19mm). Jaw width is 1/2" (12.7mm).
Serrated jaws open to 3/8" (9.5mm).
Body hole is 0.118" (3mm). Nickel-plated finish.
Weight
is 6.8oz. (193gr).
Long wires can be pulled completely through the handle
for twisting.
The
threaded head & handle have clearance holes.
A universal
work holder (India). It has 60 peg slot positions & is
supplied with eight, 3mm steel pegs.
Aluminum vise head dimensions: 2" diameter (head only) x 3-1/4" W
(head plus thumb screw) x 1-1/8" H.
Max pin-to-pin opening is 2-3/16". Overall length,
including the detachable wooden handle is six-inches.
Silicon soft grips for the 3mm pins.
To store all eight pins with the tool, I sometimes clamp them onto
a soft plastic tube.
Another custom-made aluminum hand vise that uses the same 3mm
pegs with or without their silicon grips.
The stepped base allows easy clamping
in a larger bench vise. 6-32 set screws hold the dowel rods in
place.
The
movable jaw runs on two, 1/4" dowel pins in
precision-reamed holes. The adjustment screw is M6-1.
The spring compresses into two, 9mm counter-bored holes
allowing complete jaw closure.
A custom-made Teflon washer makes turning the screw smooth & precise.
There are 50 holes.
