True, perhaps I should've specified, I'm too used to being on other forums for casting and car stuff, I meant aluminum. The temp requirements alone drop the price significantly, and you can still make a very solid part if you use the right materials (alloy requires only a modest foundry, you can use clay graphite or graphite crucibles versus silicon graphite or otherwise; much much less fuel use and you don't have to step up to oil or electric, you can just use solid fuels or a middling LPG setup, etc.).
Grant, insofar as I'm aware they're back to making them. I knew they went out of production for a while, but they've always listed themselves as wanting molds for new parts, so if you send rockers, floor pans, etc. they'll make a die and start pressing them provided the need is there. I have no major need since mine is getting hacked up to make space for suspension redesign and wheel fitment, but I'm sure they'd be happy to press out what you need since I'm sure they still have the dies.
Oh, and Yoshimitsu, comically I'm right at the upper limit of what I can melt and pour with my little Reil burner. I'm in the copper zone, currently working with an alloy called shibuichi that I've mixed myself using second hand pure silver coins and (oddly enough) old pure copper electrical wiring. Fun stuff, a bit warm in the summer, but very fun. Cuts well, polishes beautifully, and makes for fascinating colors depending on the patina process. To be fair though I'm only using hand tools with it seeing as it's jewelry for a friend's birthday gift, so I wanted to make it as old school as possible. I can't wait to start playing with lost foam and aluminum, it should be heaps easier and very easy to machine (using my factory 1uz intake manifold and a few Volvo heads I have laying around for my first run of stuff).
