Corbin SK-1-H Stripper Kit Instruction Manual

							SK-1-H Stripper Kit
The Corbin SK-1-H Stripper Kit works with
the Corbin Hydro-Press, Hydro-Junior, and Mega Mite
Presses, in conjunction with the ET-1-H jacket trim-
mer dies. It provides both automatic ejection of  the
trimmed jacket from the die, and automatic removal
of  the surplus trim material from the punch, on the
down stroke.
The kit is universal for all standard calibers, with
the exception of  one part: the stripper plate. The kit is
ordered with one specific caliber of  plate, and addi-
tional plates can be added to use
the kit with other calibers of  dies.
The part number for the additional
plate is SK-P-H (specify the cali-
ber).
The kit consists of a thin
spring-steel stripper plate, which
fits over the proper caliber of
jacket trim punch, a heavy steel
knock out plate, two long operat-
ing rods with holes cross-drilled
through them to take spring clips,
two short push rods and two
couplings, plus eight spring clips
for easy assembly and disassem-
bly.
The head and the ram guide plates of  the various
Corbin presses have two sets of  holes to accept the
operating rods. The rods drop through the holes in the
head plate (which is eqiupped with anti-friction
bearings). The knock-out plate is secured by four
spring clips, as shown. The push rods and couplings
attatch to the bottom of  the operating rod with the
remaining spring clips. The top of  the rod has two
closely spaced holes, and the bottom only has one
hole (to attach the coupling). The stripper plate is free
to move independently from the rest of  the assembly.The jacket is placed over the end of  this punch,
pushed up into the die, and trimmed to the length set
by the die. The surplus material is pushed off  the
punch on the downward stroke by the stripper plate,
which comes to a fixed position near the end of  the
stroke while the ram and punch continue down.
The exact length of  trimmed jacket can be set by
the depth gage, provided with the ET-1-H trimmer die.
The threaded bushing in the top of the die sets the
trimmed length. By setting the length of  the rod
projecting from the
depth gage bushing
so it is the same as
the desired jacket
length, you can push
the gage into the die
mouth and then set
the die’s depth
bushing to just
permit the gage to
fit into the die (so
that the gage bush-
ing just touches the
die face).
Then, the die
itself is adjusted
down, without a
jacket, so that when
the punch is in the top-most position, the shoulder of
the punch just touches the die face.  The jacket is
pinched off  at the end of  the stroke, and ejected on
the down stroke.
Depth gage is used to
set the jacket trim die
for desired length of
jacket: stripper pushes
jacket out of the die on
the down stroke.The ET-1-H jacket trim
punch is shown in position at
the bottom of the stroke.
