I have purchase a Mayhew gasket-making punch set.

[Barry Wolk]

I have coveted one of these sets for 10 years, but was never able to justify buying one until my hand got too jittery to cut gaskets with a knife, and, even at my best it was always difficult to make gaskets exactly round. This set is about $500 new, but I found one missing a couple of dies for $175.00, used. Two replacement dies were $60. It uses multiple punches to simultaneously cut the OD and ID, by using a hammer or press.

I've already made a cork gas tank drain gasket, the inner hole for the new gas tank sending unit gasket, 2 drive shaft spline seals and the inner hole of the sediment bowl seal. I'll buy the larger dies as needed.

If you're in a bind and need a round gasket 2 inches in OD, or less, I can probably get one out the door in an envelope for a $10 donation to Mittens for Detroit.com, my favorite charity.
