Casting Aluminum parts ?????

How difficult is it to cast aluminum parts???? Nothing fancy or that requires some type of special treatment.
I think I came up with an idea to fabricate a 2BBL carb adaptor that bolts to the stock log head.
Not like the one made by Clifford, but something that would allow a "direct mount" with TWO holes, not a funnel shape.

Where could I find out about sandcasting and other DIY methods for doing this????

yea i am chasing same info,

i am planning on moving into all alloy i6 motors i've looked into it a bit, so far it's looking like 40 grand to get the first run of 10 engines!! :shock: :!: :shock: :!:

anyone got any tips please post

cheers.joe.
 
Alex, you could be lucky here. Note that, nothing is allowed to be done in this field (casting) without months of procrastination on the forum. :wink: By lucky I mean that you could well find casting places to do one or two at a pop. This is a benefit of the smaller economies.

If you can make something (sample) out of wood or putty (like Bondo) take it to them and ask "how much for the patterns, and how much to cast a piece or two?"...

There are about seven patterns in a head. Only two in a manifold with no water jacket. If you can make them out yourself of some hard, heavy well-dried mahogany (or similar, just thought there could be some around), to the oversize required for shrinkage, you have your pattern set. Cast away!

There will be a little machine and hand work to tidy, but should come out fine.

Thanks for the links guys...

Al...CNC is very practical, but I don't think there are that many places that do that here, at least not for the general public....on the other hand, aluminum casting is very easy and cheap and readily available....

Adam...actually last night I was thinking of that same thing, there's a place that makes aluminum parts, I could just go and ask how much they would charge for a couple of castings.

Basically my idea is to make something that would allow to bolt the adaptor in the same manner that the Offy 3X1 intake bolts to the head, all that one would have to do is drill and extra hole right next to the stock intake hole.
I'd probably have to make two molds, one for the round log heads and another one for the flat log heads.
If anyone has detailed pics of the Offy intake I'd appreciate if they could post them, I've never seen one up close but have an idea of how it bolts to the head.

Here's something I came across earlier today. I downloaded the software but haven't played with it yet. It may be worth a shot for you to investigate.
