Making gaskets

Most of us have to make a gasket, if nothing is available. A trick I found when you have a few pieces, and try to trace the gasket, and find things move around. Lay the pieces on gasket paper, and dust with a can of spray paint. You end up with an exact copy of the original gasket. maybe you already do this, if not it really works. Stan
 
When I was in field service. I carried several rolls of gasket paper. I carried a good selection of gaskets. But of course you never had the one you needed.
 
I have a pair of heavy scissors,and the thing I use the most is a small ball peen hammer.Lay the paper on a casting and start tapping till the gasket shows up.
 
I bought a replacement thermostat for my M38a1 military Jeep from NAPA, along with a new gasket. What I got was a piece of gasket material. Told the counterman if I had known that, I'd have cut the side out of a cereal box like I used to do. Worked fine, job is done.
 
I had one of those back in the 80's. I bought it from a military auction. All I remember most about it, it was low geared. Did you keep it 24 volts? In California back then 24 volt lighting was against the law. Stan
 
Nice idea. I will have to remember it. I still trace it or measure it out cut it with s razor knife and punch out the holes with a gasket punch. It does not take long once you get the hang of it.

37 chief and others,

When you make your gaskets, leave an "ear" of gasket on the outer edge, that way you have something to hold on to when making up the joint.

504, I know that the ball peen hammer thing has been out there for at least 45 years. I have tried it and was never able to be close to keeping the material in position. How do you hold it?

I usually try to do a couple of bolt holes first, drop in the bolts and it tends not to shift. The angle of impact also helps; keeping it close to 90 degrees with the surface minimizes the tendency of the paper to shift.
 

I'm not sure how you get the inside of the gasket although worth a try unless you are spraying the paper first and setting the part on top. I've got some spray clear coat and lacquer that may not show as bad. I searched the archives a while back on gasket making and saw all kinds of suggestions. I started using a paper hole punch to work around and punch out clean bolt holes which works better than the peen for small holes like with a carb. Would peen the edges enough to get the outline and finish with scissors or blade for a clean cut.
