Does anyone make their own gaskets? Without an original gasket on hand how best can one determine type of gasket “material”, the “thickness” and the proper hole size one needs for the gasket? My last attemp at buying gaskets didn’t go very well, so I’d like to make a few gaskets myself instead. Ive already made all the gaskets needed for the valve covers on my 37 Hudson and it went well. Now I need a Water Jacket gasket with 18 bolt holes & this gets a bit more involved. Along these lines how does one pick the size of punch to use for the holes? If there is a 5/16” bolt going thru the gasket should the hole punch be 5/16” as well or something else in diameter? On water jacket which carries coolant to the engine block after cooled, I was thinking of using the Cork-Rubber matterial by Fel Pro in 1/16” thickness. Sent from my iPhone using H.A.M.B.
