Thanks guys.  That’s the info that was needed.

YBM, issue #89, Nov./Dec 2008 has an ad for copper gaskets. Probably the same outfit as Steve dealt with, but different contact info: Don't know which is current? So; Relic's Vintage Exhaust Gaskets. 1318 Continental Ave. #10, Bismark ND 58504. Gaskets are .0625" dead soft copper, @ $35.99 + $7.00 S & H. Ph# 701-223-8480. e mail; gasketgurus@alive.com

I never heard back from my laser cutter guy.

Did find some useful material spec's - the type of copper used for soft gaskets must be: C110 (ETP) O60 temper - which about 100% pure copper that is dead soft annealed. Available thickness isn't exactly to sheet metal gauge standards - there is a .0647 inch size which matches nothing ... but a smaller one at .048 that is almost nuts on 18 gauge (.0478).

Neither was cheap - so if you get a deal on useful finshed parts take it.....

OOOPS my eyes aint what they use to be... NEVER MIND

Ted, I have used these. They have a YBlock pattern available. You can get various thicknesses... Keep in mind you need O rings or they will fail.

Oldcarmark, thats the one I bought and I am pleased with it. I am going to buy another set because I just bought another 56 ford and I see a crossover pipe in the picture.

Hello Ted!Not often I can help you. Ebay item# 270459598992.Just listed.

  

Guys - how thick are the copper gaskets commonly made? I don't believe I've ever used one.

Like say...16 gauge (sheet metal)? US std would then be .0598". The 12 gauge is .1046" - assuming copper comes that way. It would have to be pretty soft stuff too, in order to conform and seal.

I'm checking with our local guy that burns out shim stock with a laser (we send him a CAD print of the shape) to see if copper is something he has worked with before...
