i do know of a laser cutting company, but, the std gaskets are four pieces, and would like it all in one section, someone must have them on the shelf somwhere for nasp engines.

you could spray a coat of paint onto a cast one and whilst still wet stick it to the flat plate you are going to use as the flange and the paint left on the plate is your template!

what material you thinking of making it from?
the problem with a flange made in one is the expansion

im going to be using stainless tubing, hmmmmmm might just have the four flanges profiled.

keep us informed on his it goes! i was going to have a bash a few years ago, but didnt find the time!

you will be alrite with a mild steel 13mm thick 1 piece flange , use mild steel for the flange as its better for expanding than stainless and yes you can weld stainless to mild steel
heres some ive done in the past
