Do you have any idea what you are expecting to pay, there is a
company not far from me that does do castings, prototyping is
a bit dear having said that prototyping are one offs of course
but low volume small quantities are not too bad. What I will
need is an applicable design  to find out what it might cost.
I don't know is that helps at all. They definitely do alloy
including aviation grade castings

I think people would pay around $300 US.
What say you people? What would you pay for a bell housing
to fit Tracy's PSRU?

Since patterns can be up to $5000 US this is a hard target
for 10 or 12 bell housings.

And then you will have the problem of weight as you will be
lucky to get the wall of a sand casting down to less than about
6 mm. The best we can do in here the states is about 3.6 mm.
If you have somebody that can do 3.6 mm I am all ears.
George investigated it up where he is (Brisban) and it was about 5 mm
as I recall. With a 3.6 mm wall the pattern must be super accurate.
And even then a certain percentage of casting are scrap.

There is no beating a high pressure  diecasting as the wall is
typically 3 mm or less. the tooling on the other hand is
$100,000 US.

Paul,
Totally accurate and I agree with your assertions. My investigations into
die castings is that Taiwan will amortise the pattern casting if you
purchases 1,000 or more. I thought that was good of them!
