On my current Webster build, the plans call for a head gasket, preferably from 0.015" copper. I couldn't find any localy, but did come up with a piece of 0.015" brass. Will brass work in this situation?---I know its not as soft as copper.---Brian

Where did you buy 0.020" teflon?

Brian what size copper do you need?
McMaster Carr has both copper or tefon in .015 thickness the smallest piece of copper is $20 of Teflon 6; by a foot is $5.
I sent a pm

Brian,
If you want to use copper, check with your local crafts store for copper tooling sheet. I have seen it in small sheets ranging from about 0.004 to 0.018 thick. I bought a small roll of 0.005 years ago that I use. 0.005 is 36 gauge and 0.018 is 26 gauge.
For slightly thicker copper gaskets, I split a short length of 5/8 copper plumbing pipe. After annealing it can be flattened into a sheet about 2 inches wide. Mine measures about 0.024 thick. I use it to make spark and glow plug gaskets.
If you use copper, be sure to anneal it before installing it EACH time. It will work harden when you bolt a head down, so if you remove the head you must anneal it before reinstalling.

Thank you, Gentlemen, for all the good information.---Brian

Brian,
I don't see why you couldn't use brass for a head gasket as long as you anneal it just like you would do for copper. McMaster Carr sells aramid fiber gasket material as thin as .015". It is pretty tough material and has worked for head gaskets. On the other hand, Jerry Howell designed some beautiful engines, and he didn't use head askets on many of his engines. He used a .005"-.010" cylinder liner projection above the cylinder which was clamped by the head. He told me he never saw one of these leak.
