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.

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. Tom Sent from Windows Mail From: Thomas Mann Sent: Monday, December 9, 2013 7:14 PMTo: Rotary motors in aircraft 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.
