Right, catching up here...

The shrinkage was factored in but for the life of me I can't remember the %, might have been about 1% but I can always find out if really needed. Can out spot on I know!

I've got one prototype left but this does not have the shrinkage if that's any good to anyone. It's a bit brittle though.

Chasmon, can you make these resin parts then? What materials do you think would be strong enough? Could you use my spare prorotype as a pattern?

Bell mouths were again modelled up and rapid prototyped (based upon the GSXr's), so I've only got 4 (I've got 2 sets of the GSXr's if any one is interested in these.

I have experience of the process at work and we have the kit, however I would not do a homer like this though.

To be honest I'd be keener if you had a prototype for a Zetec :p It may be worth your while finding out how much a vacuum casting company would charge. I'm guesing their labour costs (its intensive) would be the major cost...

Calling for anyone with access to vacuum casting kit!

I can find out what material would be suitable though for you.
