Gasket for Hoglet cylinder heads
« on: November 23, 2017, 01:25:33 PM »
Hello Everybody.
The drawings for the Hoglet makes no mention of any gasket for the cylinder heads. Can those that have built this engine please tell me what they used as a gaskets. I presume that a gasket is needed, cant imagine that a gasket less joint will be gas tight at pressure.
If gaskets are used what material are they made from.
Thank you
Trevorc

There is no need for a gasket as it has a narrow "squish band " of metal approx .125 wide around the rim of the cyl.
I have made 5 Hoglets and not one has needed a gasket. It's the same principle as a model airplane engine.

I have never had luck sealing cylinder heads to cylinders using "squish bands". Use a piece of 0.030" general purpose gasket material from your local automotive supplier. It's cheap and it works, and the heat doesn't seem to bother it.---Brian

You could use a thin anealed copper gasket if you are worried that it will get too hot for a paper type one.

I use .015" teflon sheet for my Hoglet. Been on there over 4 years. No problems yet.
