Brass Castings From Plastic
David Braun, formerly of PSC, now owns The Back Shop
and does brass investment casting from plastic masters.
He has a complete site with lots of stuff on it, but also
has a page that answers a lot of questions on the process
used to convert plastic patterns to brass castings.
It's very informative.
I haven't been able to get it to open this afternoon,
but at about 1:00 AM this morning, it worked fine.
You can also try "googling" this;
Making Brass Parts from Plastics
K&D Castings does not have a web site that I've been able to
find, but I do have their phone number and the owners name.
I'll provide that off list.
