Gasket Making 101

Someday your going to need a round gasket you don't have, can't buy or don't want to buy. In my case that's always been the N's over-the-counter oil drain plug gasket. An ill fitting total POS and the reason I made this tool.

You can make your own for the price of the gasket material. This is 3" X 6", got 1 moving part and was made from scrap riding mower deck pieces and a utility knife blade. I narrowed the blade with a cutoff wheel on a dremel tool and heated the lower part so a hole could be drilled thru it. The rest should be self explanatory.

To use it the cutting board needs to be secured to the surface it's sitting on and the gasket material needs to be stapled to the board at the corners and in the center of each gasket your cutting. Made in '08

Olfa and others make similar circle and rotary cutters, only plastic, which can be found in art and crafts stores. Not nearly as pretty as yours though!
 

Nicely done, much nicer than the junk sold in craft stores and heavy enough to even cut through thick leather.

I currently have an x-acto beam compass made of zinc that holds an x-acto knife handle and blade on one end and a point on the other
end. It will cut circles from 1/2 inch up to 15 1/2 inches. I've cut many gaskets with it. Probably no longer made though..........
 

I learned to make gaskets in the Navy using only a ball peen hammer. I made my share of them too.
 
There is a dri-wallers tool made to cut circular holes for light fixtures, that could easily have a knife blade substituted for the cutting wheel. BTDT. Nice work BTW.
 
Thanks for the replies and suggestions but I wouldn't trade what I use for anything mentioned here.

What I would like to see are some gaskets you posters have made and the cutter you made them with.
