Cork Gaskets

FWIW - After a bit of experimenting I was able to get a nice clean cut on some rubberized cork gasket material both 1/16" and 1/8" thick. I used double sided tape to hold it down. I thought I’d share my settings in case anyone else comes across a need for a hard to find replacement gasket.

1/8" 2-flute straight cut bit, HSS
max RPM on my Dewalt 611 router, 27000 RPM
800 mm/m feed
Conventional cut, not climb cut
1 pass, full depth


Awesome and very useful. I added a tag so it is easier to find, thannks for sharing!

That’s pretty slick.


I could really have used something like this when I was building my engine.

Actually, I think the throttle body gasket is still a chunk of cereal box cut with a Stanley knife…
