Hi JB,
         I hope you do try it and let the rest of us know how it's done. 
The whole process looked so simple - once you had the master and the right 
equipment! They were making split moulds to be able to remove the casting 
but I did not pay too much attention to how they did this. Their moulds 
were re-useable unlike the iron founders I use who break the mould off the 
casting - at least for "one-off" jobs like we have made.

Keep the revs up (or down)
