    No, it was a foundry somewhere in Washington state. I'll try and find the info on it.

    Did you have to "face" them in a mill to be sure they are flat and even at the mating surface? I hear this is a big problem with the 348/409 Offenhauser covers.

    I would think you could make a fortune building valve covers that look like yours for any engine out there. I would sure be interested in some for my 348.

    I agree on the Moons, they are TOO refined.

  11. Those valve covers are Finnish!:D :D Good job

    Thanks for posting pics, I have some ideas in my pea-brain and now I have inspiration to make up some plugs...

    For others with ideas, don't just be looking for industrial foundrys. There are artistic-type foundrys out there that make bronze sculptures that do VERY small runs like we'd be prone to do.

    Also, if you find a fin design that you like on a part that is already made, you can copy them with brush on stuff called "Vultex", then cast them in resin and use them to "fin" a ordinary (easier to make) shape that already has the shrinkage figured to use as a plug.

    There's a "how to" on this site http://www.fgci.com/ (gotta patronize local companys dontcha know).

    That's some really beautiful work! I grew up next to a foundry, so I've played around with sand casting a little. If anyone wants to try it themselves, you might find this interesting.

    Carb-Otto,
    Great work and fantastic results ! Teck week has just started and you've got it nailed already.
    For those of you considering making your own patterns for casting there are special rulers made that compensate for the shrinkage factor. The shrinkage is different for each type of metal being cast, ie aluminun, cast iron. bronze, ect. so you have to get the ruler for the specific metal being cast. I don't know just off hand where to get the rulers but any of the home casting sites should have the info available.

  25. If anybody wants a special ruler, I can draw one with AutoCADand shrink it accordingly. Then I'll laser print it and send it to you. You glue it to a stick and cover with a couple coats of varnish. HAMB discount - free! Send me a P.M.
