& self-extract.
5C Collets
70 piece
5C collet set 3/64"
(0.046875") through
1-1/8" (1.125") in 1/64th-inch (0.015625")
increments.
A 5C collet has a relatively small gripping range.
Best accuracy is +0 to -0.002" Above +0.005" may
damage the work, below 0.010" may damage the
collet.
1/32" (0.03125") increments are too large of steps.
Most 5C collets are open all the way
through.
Labels help locate the different collet sizes.
An emergency 5C collet that can be machined
for a specific
use. A set of square, 5C collets.
Phase2+
spin index that uses 5C collets. Hardened &
precision ground spindle.
Spindle accuracy 0.0004" TIR.
Cylindrical center base (per inch) .0012"
concentricity.
Spindle centerline parallelism to base 0.0008". Precision
ground 36 position index
plate.
Direct indexing in ten,
1
degree steps; graduated
scale
in 5 degree increments.
Excellent price to performance ratio.
5C Spin Index manual.
Used a ball-nosed end mill so the
bottom of the slot would
have a radius.
Milled base
(top surface)
for flatness & clearance
for
mounting bolt nuts with coupled washers.
Spin index mounted onto Taig mill which has 1-inch
on-center T-slots.
Bolts are 2-inches (slots) apart.
The spin index fits the larger
RF-25, much better (below).
Milled 3/8" bolt-down slots. This is a good
place to use the 3/4" shank,
ER-16 extensions.
Index & a diamond wheel being
used to sharpen a HSS slit saw.
Used the spin
index to cut a series of odd angles
to reproduce a broken plastic speaker wire
retainer clip.
Finished the pivots with a small square diamond file.
ER-16 collet extension pair (USA) having stubby (3.65") &
long (6.3"),
3/4" diameter shanks.
These are
very
precisely made extensions with a collet lock nut 13/16"
&
there is an inside back-up hex set screw with
left-hand
threads that is set against the end mill base.
The Martin
Tools
open-end wrench is thinner, flatter & shorter than
a standard type making it easier to use
in tight areas.
The collet is
snapped into the nut before tightening.
These extensions are made by
Craftsman Industries in NV.
5C Fixtures
Four-sided &
six-sided
hardened,
precision ground
5C collet
fixtures with clamping nuts (Taiwan).
Tighten & loosen
using an adjustable pin spanner
wrench. Lever moves a cam for fast clamping.
These are
some of
the most useful fixtures in my shop.
The collet-closing nut leaves little
edge so
ultra-thin parallels are
used.
Used the hex fixture to make M8-1.25
transfer screws from threaded
stock.
The tips were subsequently heat
surface-hardened using
Kasenit compound.
My
bench vise has milled aluminum
soft
jaws to help protect parts.
Milling slots in a 3/8" to 5/32" brass reducing
sleeve.
Coated with
Dykem dye.
Pin Spanners
Other types of pin spanners.
Horizontal & vertical angle 5C collet quick-release fixture.
Type 225-202C
manual.
5C Collet Depth Stops
Collet length extension.
Adjustable depth stop
for a
5C collet screws into back inside
threads.
Universal 5C collet stop with 1/4" & 1/2" diameter
spring ejectors & solid stop
assemblies (USA).
The body did not fit inside all of the 5C collets so
it was
precision ground using the
tool post grinder.
The body end bolt screws in, to expand by cam action,
two
flat springs that lock the ejector into the collet.
A wooden holder for the different
5C stops.
5C Lathe Chucks
3-jaw, 4" chuck with an
integral 5C
collet back.
4-jaw, 3" chuck with a 5C collet back.
Spin index with 4-jaw chuck.
V-Blocks
V-blocks hold round parts very accurately,
repeatably, & securely. A
V-block spec.
Micro V-block set for holding very small parts.
Along the top
are bridges, then a (white) desiccant container,
two differently sized hardened & ground wee blocks
with their clamps, plus an
assortment of prisms sizes.
The wee V-block itself is held in a larger V-block.
Blocks shown with (left) & without (right) an upper prism.
Note the bridge to the right, under the main
locking bolt, that allows holding extra-long
parts.
Mini V-blocks: Dimensions: 1-3/8" or 35mm
(L) x 1-3/8" or 35mm (W) x
1-3/16" or 30mm (H).
Capacities: max 19/32" (0.59375" or 15mm); min 1/8"
(0.125" or 3.2mm). The
reversible clamps are within
the blocks' dimensions so they are compact & can be
clamped deeper into a vise
than standard designs.
Added 5mm washers. For scale, a 1/4"
dowel is shown clamped
into the V-groove.
Intermediate-sized V-block
set (India).
All surfaces precision ground within 0.0005".
1" capacity: 1-1/2" (L) x 1-1/4" (W) x 1-1/4" (H).
1-1/2" capacity: 2" (L) x 1-1/2" (W) x 1-1/2"
(H).
1" & 1/2" dowel rods shown clamped in V-blocks.
Large V-blocks; 3
x
3
x
4" (7.6
x
7.6
x
10.2 cm)
hold 2-1/4"
(5.7 cm) diameter round parts
(India).
This style allows easier (deeper) clamping
in other fixtures like a vise.
Each block weighs 8 lb (3.6 kg).
V-block
specification sheet.
Three different V-blocks compared for size & style.
Dimensionally matched V-blocks
incorporating a stepped design (import).
Clamps have screw holes at 45 deg
&
90 deg to hold either
square or round
parts. Stepped
groove construction
has
high or low clamp mounting for small or large
pieces.
Clamps do not project over
the width of the block,
permitting
it to be used on the base, ends or sides. The steps
allow
parts to be clamped/unclamped while
held in a fixture.
Examples of high & low stepped clamping positions.
The blocks are gripped in the
mill vise jaws with their
clamps set in the low-step position holding a 3/4" rod.
A square part held with two clamps in
the
low-stepped position, using the 45 deg set screws.
Steel tool drawers can store a lot
of heavy tooling in a compact space.
This open-weave drawer liner has anti-microbial
properties that prevent bacterial growth.
The non-slip black cushion protects the instruments &
keeps them from moving
(banging) around, too.
Variable-angle V-block. There is an etched degrees
scale with
a minutes precision vernier (nonius)
scale.
Prismatic V-jaw for 6" (15.3 cm) Parlec
vise. 1.9" (4.8 cm) height.
Hardened to RC58-62 & precision ground.
The back has two keyhole slots that
allow it to be
bolted in place of the OEM vise jaw, if needed.
A hex wrench accesses the bolts through the front holes.
Multiple Vees are in the face.
Two, one-inch (25.4 mm) dowels are shown, clamped.
Making a 30mm
broach cutter
bushing.
Example setup using multiple V-blocks.
A 1/4" end mill is being
used to cut a recess thus
allowing use of the longer Chapman gun
screwdriver bits which have a small,
round nub.
Another V-block part holding example; a
fly cutting
operation.
A power feed can help produce an excellent finish.
Fixed angle set: 1 deg, 2 deg,
3 deg, 4 deg, 5 deg,
10 deg,
15 deg & 30 deg.
Hardened & precision ground; very accurate.
Hardened, 1/4" thick, precision-ground angle setup
plates:
1 deg, 2 deg, 3
deg, 4 deg, 5 deg, 10 deg,
15 deg,
20 deg, 25 deg, & 30 deg.
Hardened, 1/4" thick,
precision-ground 30-60-90
deg & 45-45-90 deg angle setup plates.
Can be used with a jig to set
up the
lathe's compound angle.
Tilt Tables
16.5 lb (7.5 kg)
5" x 7" x 3-1/2"
(12.7 x 17.8 x 8.9cm) tilt table.
Range of gear adjustment is +45
deg
to -15 deg
unless the
crank is removed & then adjusted by other means.
Worm gear adjusted with a hand crank.
Table locks under
both ends.

Table locks
under both ends.
This model
has no
worm gear for free adjustment
of the full range; no interfering crank.
Adjustment
range is +/-45 deg.
Three T-slots & a surface accuracy of
+/- 0.001" is sufficient for most milling
operations.
An adapter plate
made from
MIC6 was fabricated to
mount the
4" rotary table centered on the tilt table.
The plate material is
MIC6
aluminum.
Three 10-32 cap head bolts hold the rotary table.
The close-tolerance holes (#9)
are 3/8" counterbored.
Hardened

one-piece, precision
ground flat,
square & parallel to 0.0002".

Precision-ground (slotted & solid) gray
iron angle plates are superior to milled types.

Top-Bottom: 3" x 3-1/2" x 4", 4" x 4" x 4",
2" x 2-1/2"
x 3", 2-1/2"
x 3" x 3-1/2".
Remove oil spots before using the surface plate.
Screw Jacks
Screw jack set. Two jack sets can be handy to add support
to mill
table setups. Range with spacers is 2-1/4" to 6-1/4".
Dowel Pins
An assortment of differently
sized dowel pins are handy:
3/16", 1/4", 3/8", 7/16", 1/2", 5/8", 3/4", 1" sizes
Dowel pins come in a huge variety of sizes,
precisions,
& quantities.
Depending on the needed fit (loose, tight, interference) pin
diameter
can be specified to be plus, exact, or minus a given size.
For example, a
0.5000"
precision reamed hole
might need a 0.4980" diameter pin for a tight fit.
