PCM-1
Power Cannelure
Machine
Cannelure 100 bullets/minute
Weight: aprox. 70-lbs.
Power: 110-120 volts 60 Hz.
Motor: 1/4-HP Gear drive.
Forced air cooling: 100 CFM.
Rust resistant, baked-in powder-
coated grey finish on both the
steel frame and the heavy gauge
steel cover.
Built-in 5-amp circuit breaker and
switch with bright pilot lamp, for se-
cure continuous heavy duty operation in
a production line or on the bullet-makers
bench.
Massive thrust bearing adsorbs the powerful forces that roll precision
cannelure rings (serration grooves) into copper, aluminum, lead, gilding
metal, brass, or even mild steel bullet jackets. A set of precision spacer
disks provides cannelure height settings that cannot vibrate out of ad-
justment. The PCM-1 comes with a set of spacers, Allen wrenches to
adjust the depth and lock the back plate into position for the bullet diam-
eter, a universal 224 to 475 caliber back plate for cannelure rolling (op-
tional knurling back plate is available), and one diameter of cannelure
rolling wheel (PCM-W) which covers a certain range of calibers (see chart)
within the back plate adjustment range. Custom wheels can be made to
order for multiple grooves, special widths and angles. Simply feed bullets
in one side of the channel, and they come out the other side evenly
cannelured.
Special back
plates also
required for
these larger
calibers.
The PCM-1 uses one of six standard diameter PCM-W cannelure wheels
to fit the range of calibers from .224 to .510-inches. The wheels have a
key that slips over the vertical shaft on top of the tool. A rotating plate
carries the bullets around, while spacers fit between the plate and the
wheel to position the cannelure vertically on the bullet. The spacers are
.027 and .048 inches thick, making it possible to stack them in various
combinations to achieve any practical position for the cannelure ring. One
PCM-W wheel is included in the price of the tool. To select the proper size
wheel for a given caliber of bullet, refer to the chart. Wheels are stamped
with an identification letter from A to F, which specifies the range of cali-
bers as shown:
Caliber Code Wheel Diam., Inches
.224 to .257 A 2.100
.258 to .308 B 2.014
.309 to .358 C 1.900
.359 to .412 D 1.815
.413 to .458 E 1.710
.459 to .512 F 1.615
.512 to .600 G 1.515
.600 to .690 H 1.415
.690 to .800 I 1.315
.800 to .900 J 1.215
.900 to 1.00 K 1.115
Standard cannelure width is .050-inches with
a vertical serration. The raised portion of
the wheel, which impresses the can-
nelure, is offset from the center of the
wheel, so you can turn the wheel over
providing different cannelure posi-
tions, in addition to the spacers.
Wheels are held in place by a collar,
which is clamped to the shaft by a
single set-screw, which MUST be
clamped against the flat of the
shaft, never on the round surface
or the keyway slot. Rubber feet
under the case provide for air flow
out the bottom of the case: do
not remove them.
