[SEL] Pattern and corebox.....

[James Mackessy]

Beautiful job, Curt. I think most on the list understand the process, but
one thing I have a tough time explaining to people is the concept of a
corebox. I guess they've never thought about it enough realize that to get
hollow castings, there has to be a "mold to make part of the mold". Your
pictures are worth a thousand words. Good luck on the castings, looks like
they'll come out well.
Best Regards;
Jim Mackessy
