RE: [ihc] Copper header gaskets for a SV

["Tom Reed" <treed@xxxxxxx>]

I was going to take some 22ga solid copper wire and use it as an "O" ring
around each exhaust port. If what I have doesn't seal well enough then I
might pull the gaskets and try adding it. Thanks for the alloy info I didn't
know what to ask for and I was looking for copper flashing at roofing supply
houses. This was probably cheaper though.

Check for Copper AISI alloy 101000 in a dead soft condition. This alloy is
also called OFHC (oxygen free high conductivity) and I've used it for seal
gaskets used with knife edge seals in semi conductor fabrication machines.
Places like Metal Goods, or Copper and Brass Sales carry it in thicknesses
from .01 to large number of inches thick. Given the vendors I suggested you
might end up with more than enough..

I had a hard time finding copper plate. I also wanted the copper as soft
possible. I've annealed copper to soften it in the past, but I don't have
the facilities to do it properly here.

Besides there is a certain elegance to using common hardware store times ;~}

Sounds like a great idea, Tom. Is copper plate not available? (Looking for
the easy way out)

Isn't it funny how Stan uses those 3/8's bolt heads to tighten down the
flanges. I can see why, and it works, but it looks funny to me.

I sure hope it works, as I'll need gaskets soon.
