GETTING
STARTED : |
|
| |
- Determine dimensions of gasket to be cut. Remember to
always cut outside diameter first.
- Locate center of gasket to be cut and mark your material.
(A.) Make sure you have enough material to accommodate the
complete outside diameter of gasket to be cut.
- Puncture gasket material with piercing tool or center
pin creating a pilot hole. Use care not to enlarge or elongate
pilot hole as oversized or oblong pilot holes lead to oblong
or eccentric finished gaskets.
- Loosen cutter head screws at end of the cutter block.
(B.)
- Extend cutting blade slightly beyond thickness of gasket
material and re-tighten cutter head screws.

CUTTING
GASKETS 1" TO 13" IN DIAMETER: |
|
| |
- Insert thick-headed pivot post without offset pin through
cutter block.
- Use 0"-13" scale on cutter block. Match line
through pivot post with desired outside diameter dimension
of gasket to be cut on scale. Secure with knurled nut.
- Place center pin into pilot hole in gasket material. Insert
protruding center pin into recessed ferrule in middle of
cutting board. (C.)
- Position pivot post in cutter block over center pin in
gasket material (D.) ensuring cutter block is flat on cutting
board and material.
- With slight downward pressure on cutting block and material,
rotate cutter block clockwise to make cut.
- Reset pivot post for inside diameter dimension and cut
as above.

CUTTING
GASKETS 13" TO 25" IN DIAMETER: |
|
| |
- Place extension bar without stud in groove on bottom of
cutter block with single, large hole in extension bar toward
cutting blade.
- Insert thin-headed pivot post through large hole in extension
bar, through the cutter block.
- Use 0"-13" scale on cutter block. The extension
bar adds 12" to capacity of block. To cut a 16"
outside diameter gasket, match line through pivot post with
the number "4" on scale. (E.) Secure with knurled
nut.
- Place small hole at tip of extension bar over center pin
in gasket material (F.) ensuring cutter block is flat on
cutting board and material.
- With slight downward pressure on cutter block and material,
rotate cutter block clockwise to make cut.
- Reset pivot post for inside diameter dimension, and cut
as above.

CUTTING
GASKETS OVER 25" IN DIAMETER: |
|
| |
- Place extension bar without stud in groove on bottom
of cutter block with single, large hole in extension bar
toward cutting blade.
- Insert thin-headed pivot post through large hole in extension
bar, through the cutter block.
- Use 0"-13" scale on cutter block. Each extension
bar adds 12" to capacity of block. To cut a 32"
outside diameter gasket, match line through pivot post with
the number "8" on scale. Secure with knurled nut.
Proceed to add an additional extension.
- To add additional extensions, use extension bar with flush
mounted bolt. Insert stud up through the outer hole on extension
already in cutter block. (G.) Secure with knurled nut.
- Follow steps 4 through 6 in above section entitled "Cutting
Gaskets 13" to 25". (H.)

CUTTING
SMALL GASKETS OR WASHERS: 1/4" TO 2"IN
DIAMETER: |
|
| |
- Insert pivot post with offset pin through cutter block,
keeping pin toward blade.
- Use 0"-2" scale on cutter block. Match line
through pivot post with desired outside diameter dimension
of gasket to be cut on the scale. Secure with knurled nut.
- Place offset pin into pilot hole in gasket material. (I.)
Insert protruding offset pin into center of rubber on wooden
cutting knob. (J.)
- Hold cutting knob and material steady, with slight pressure,
rotate cutter block clockwise to make cut.
- Reset pivot post for inside diameter dimension and cut
as above.

CUTTING
FLANGE BOLT HOLES: |
|
| |
- Locate center of desired bolt holes and proceed in same
manner as cutting small gaskets.

HELPFUL
HINTS : |
|
| |
- When cutting thick or dense materials, make several cutting
passes, increasing blade depth on successive passes.
- For very thick material, in addition to making several,
deepening cuts, it is sometimes advisable to turn material
over and repeat cuts on reverse side.
- For larger diameter cuts, use corner ferrule of the cutting
board. Cut a 90 degree arc, rotate block and material counter-clockwise,
cut another 90 degree arc, and repeat process until entire
gasket is cut.
- Many who frequently cut multiple, or large gaskets will
insert a ferrule in the top of a worktable, and use the
entire table as the cutting board. Using a fiber pad or
soft wood workbench surface will prolong blade life.
- Store tool with cutting blade recessed in cutter head
to enhance blade life and avoid accidents.
- Avoid excess pressure on cutting blade and center pins.
- Cutting rubber or grabby material is usually made easier
by wetting area to be cut with soapy water, or other lubricant.
Warning: make sure whatever lubricant you use does not adversely
affect integrity of gasket material.
