Paul,

when I talked about asking for your help on my side housing castings, I was thinking what you mentioned to me regarding pattern making. You said that you had
specific information about requirements and techniques. I am getting to the point where I have to look for ways to get or make pattern.
Also, could you let me have the POC at the foundry you used in the past. I need to make sure I can get the right material and heat treatment if necessary.
Would surely appreciate if you could give me a hand here.

I'll be glad to help you make the patterns out of wood Richard.
I just can't make them for you right at the moment as I need to upgrade
my NC mill.  In the meantime I can recommend a book Called Wood Pattern Making
by Herbert J McCaslin ISBN 1-55918-205-9 Lindsey Publications Inc.
The foundry I use is American International in San Fernando Calif.
They can do walls as thin as .140. Ward H. White is the owner. 818 365 8000
Tom answers the phone. They cast 356 and heat treat to T6 as a matter of course.

If you use this foundry and there is a problem they can call me and
I can stop in. 

If you have some Rhino drawings send me those so I can take a look?
