and I hate welding galv enough, but I've researched the hell out of it and
have all the material. Just not even gonna bother doing practice pours until
the patterns are ready, thanks for the heads up though.
The piece I was talking about forging was a 70 year old Acme pipe label that
I wanted to flatten and make a belt buckle out of. So brittle. Bye bye
antique. I was sad but then a friend brought over a really old emblem from
some sort of V12 car and I made bronze buckles out of that instead, which
turned out pretty awesome, albeit ridiculously heavy for a belt buckle.
Not interested in cast iron in the slightest though. ZA is more than
interesting enough for me.
