Rob,

Let me work through one of these. If it goes well, I’ll work something out with you.

I’ll post a picture of the model before (and after) it’s poured.

Hi Thomas,

I might be interested in getting a copy of your intake manifold if you are doing it for a 20B. Would it help reduce your cost if other people bought copies.

Can you tell us more about your manifold design and what I would have to do to get a copy?

Thanks.

I managed to hook up with a art/sculpture group that can cast my manifold using the “Lost-Wax” method.

This is much more accurate than Lost-Foam and is something that would be fairly reproducible in the even that a pour goes bad.

Hopefully I will have a finished product by the end of January.

From there it will be a matter of having the part heat treated followed by final machining.

I am working on my intake manifold. I have it fashioned/modeled out of Styrene and will be having it cast in aluminum using the “Lost Foam” sand casting technique.

I am looking for a ceramic coating material associated with this process as well as some fillet wax.

Anyone out there have a source for the same?

Thanks.
