Hi,

I am used to work with epoxy and glass moulds, but now I am going to produce cylinder heads and intake tubes for a 1/4 scale dummy rotary (LeRhone). I have heard that using polyurethane resin in silicon moulds is a perfect method for this. Can anyone explain how to do this or know of any links describing it? Thanks in advance!

Cheers,

Magnus

PS Is it spelled mold in the US? The Spell Check attacked all the moulds.
