Where can I get some blank head castings? I've got an NHRA friend who thinks he can make some power. And I'd rather not buy a whole block of aluminum.

They better be selling ALL of them very fast, or they'll be sitting on the shelves indefinately...

Spending 1300 bucks for a caswting that still has the same issues with spark plug cracks really isn't that smart...

You will all be amazed come the middle of May.

i bet your new heads would work swell on a 2056 jake. again, that's the bare price. throw stock valves, springs, keepers, shipping, etc, into the the mix and you'd be well over $1.5k, EACH!!!. fmtt.

lost foam would take care of some of those problems...too bad it's too expensive for us mere mortals (IMG:http://www.914world.com/bbs2/html/emoticons/sad.gif)

then you have to fab up a core box to make the cores in. when your neighbors call the epa will we see a "furnace" for sale in the classifieds? (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

Who the F%#@ is Oddball. I've cast gold alloy with lost wax. Not exactly foundry size though.

Hey Mike start with something easy like a belt buckle. I know a part I'd like to see. Those silly things that mount the visors to the windsheild frame. The plastic sucks after 30 years.

I have thought about that part, it would have to be a really nice surface finish if one was to leave them bare or want to polish them....

trust me, I plan on starting off with something dirt simple.....

Maybe you can tell Mueller what that molding plastic stuff is dentists use to make molds of people teeth when you make a new crown. Self hardening in 5 minutes.
Like stuff would be the hot ticket to make part molds that you could use in the lost wax process.


I admire Mueller trying out the casting process, I might try this in Suriname where there are not effin rules. Hell, there are hardly any police for that matter. Lots of small casting equipement around as there are 300 jewlery shops due to the gold rush.

while I have never done the casting process myself (melting, pouring, being a sand crab and what not), I have designed parts to be cast (for work) and have visited and dealt with a few of the foundrys in the area (too f'n hot, there is no way I'd want to work in a foundry unless it's 30° outside (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) )

i'm sure I'll make some mistakes and it'll be a learning process, but I look forward to it (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif)

Last fall I had a short project at a place that made silica glass in a continuous batch process 1800 degrees at the furnace draw, a bit cooler as it fed into the molds, but still toasty warm. This is about a 4" diameter ribbon of glass

So that's why you were so interested in that 3-D printing service! Molds. Would that be "lost plastic stuff" casting?

Not to mention the electrical requirements to smelt aluminium. One of my professors worked for ALCOA, he is always talking about how how big a pain in the ass it is to melt aluminium.
