How to Cut Gasket material?

Clean radius and straight cuts are achievable on gasket material with the proper tooling. Thinner types of gasket material require nothing more than sharp blades and hollow gasket cutters. Gasket material over 1/4-inch thick require specialized mechanical tools to create the precision cuts necessary to seal a piece of equipment and is best left to professionals. Properly securing the gasket material and ensuring the tools used are in good condition will allow you to cut thinner gasket material efficiently and precisely.

Difficuly:Moderately Easy


Things You'll Need:

1/4-inch plywood

Steel rule 

Paint marker

Utility knife

Circle gasket cutter

Hollow gasket cutter set

Dead-blow mallet

1.Set the 1/4-inch plywood on a firm flat surface.Place the gasket material on top of the plywood.Using gasket cutting tools withaut plywood will cause damage to vital tool components.
2.Measure and mark a rectangle sired to the length and width of the final gasket sire with a steel rule and paint marker. Do not use a permanent marker on rubber-based gasket material.
3.cut along the marked lines with a utility knife,using the straight edge as a guide.
4.Mark the center of the rubber gasket material for a round gasket or mark holes needed for fasteners on rectangle gaskets with a paint marker.
5.Set the center pin of the circle gasket cutter on the cantor mark of the gasket material.Loosen the thumb screw located on the side of the cutter.S lide the cutting blade(s)to the edge of the cut gasket material.Tighten the thurnbscrew.while applying light pressure toward the su而ce of the gasket material,spin the cutter in a clockwise direction to cut the circle gasket.Adjust the cutting blades as described to cut and remove the inner section of the round gasket.
 6.Align the hollow gasket cutter from the cutter set that matches the size of the hole required in the gaskt material.Strike the back of the hollow gasket cutter hard with a dead一blow mallet. Pull the hollaw gasket cutter from the surface of the material.If the hole plug does not came out with the hollow gasket cutter, realign the cutter blade with the scored hale and repeat the process until the plug removes from the gasket material.Reqeat the process to cut all hole locations in the gasket material.
