After a bit of googling around I found this machine for sale from a couple of places in the states. It looks good, almost too good for the price point (around $400). It claims it's for casting with metal, but I doubt there would be any problems casting with resin (or even molten plastic). Anyone know if this would be suitable for casting up miniatures of a similar level of detail to GW ones?

I've done casting at a professional level before (photo frames!), but I was working with pewter (a very maleable and forgiving material). I used a centrifugal casting process, which spins the mold very quickly as you pour the casting material in, pushing the pewter out to fill the mold. Is the process of casting resin more forgiving or more difficult than metal? I guess resin doesn't need to be heated, so I don't have to worry about the resin cooling before it fills the mold, so is air channelling the only thing I have to worry about?

I think most resin casters use Pressure chambers rather than vacuum chambers. The vacuum will pull the air bubbles out - but it will not force the resin into the smallest chambers of the mold. ]]> http://www.dakkadakka.com/dakkaforum/posts/preList/325154/2068971.page http://www.dakkadakka.com/dakkaforum/posts/preList/325154/2068971.page GMT
The other trick with resin is vibration. You can vibrate the mold to get the bubble to the top. I'm sure I don't need to tell you the best place to procure small, discrete, vibrating items...

Anyway, search for Vibration Tables and you'll find some pretty decent tuts out there.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/325154/2068997.page http://www.dakkadakka.com/dakkaforum/posts/preList/325154/2068997.page GMT
There are some things you need to do to the pressure cooker, for it to work properly. You have to drill out a hole and insert a fitting in the lid of the pressure cooker. Then you have to disassemble or stop up the two emergency release valves on the lid.

If you attach the spurs correctly to your piece, you shouldn't have any issues with the resin getting in the tight spots of the mold.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/325154/2069161.page http://www.dakkadakka.com/dakkaforum/posts/preList/325154/2069161.page GMT
