So, I had this idea to make a sand-cast aluminum part, and took a similar one to a foundry my buddy recommended.

Short story long: I need help with patterns. I've read a bunch of stuff on patterns, and on casting - both here, and on the HAMB and elsewhere. But at the end of the day, you're going to have to make a bunch of pieces as part of the 'learning curve'.

Anybody here in the PNW do this work?

Thanks in advance!
