Homemade Gasket Punch

Gasket punch kits, or punch kits in general are usually expensive and hard to find. Most hardware stores and automotive stores do not carry these kits. Many a time, you will only need one size to make a gasket -- and often times this choice is cheaper.

A typical roll of it runs between $3.00/USD and $7.00/USD depending on thickness and size. It comes in many different gasket types including cork and rubber/paper.

Punches are usually tubes with a sharp end on them that are struck into the gasket to cut a portion out. In this article I will show you a use I had for a rear-end gasket job.

Notice: This is a half-ass job, using two gaskets -- it was temporary.

First:

Use a micrometer or other measuring device (bolt shank would suffice) to find the correct size of the holes you'll be making:

In my situation, the holes are 3/8" big.

Take a trip to your local auto store and grab a 6" piece of brake line and verify that the inner diameter meets your required size. (Slightly under will be fine, just harder to get the bolts through. Slightly over will possibly cause a leak.)

While being careful not to smash the line (the structural integrity of the brake line is key), place it in a vice and cut the flare off -- try to do this a straight as you can, and perpendicular to the length of the line.

Use the tang of a file to deburr the inside:
