If you do indeed fancy having a go yourself John Winter supply a super service and their web site is http://www.johnwinter.co.uk/ Good luck - regrettably we only cast iron and bronze in our foundry.

Keith Andrew, You could use sodium silicate mixed sand which is set by passing CO2 thnrough it - very simple. Buy dry bagged silver sand from a builders merchant - mix in about 3% sodium silicate by weight, ram and gas simply by inverting a funnel over the mould and releasing your pub gas into the funnel via a rubber tube. I can let you have some sodium silicate (waterglass) if you don't have a local source) AWEM > > On Sun, 20 Sep 2009 02:08:04 -0700 (PDT), Andrew Bishop > [quoted text clipped - 44 lines] > > AWEM That would be the ideal I had my hand reproduced in ali using this method and the detail was good when i enquired about buying some it was only in large barrels if I could purchase some of you that would be perfect or if you know of a suppler who sells small amounts as i understand it has a shelf life .

Thanks Andrew Yes it probably does have a theoretical shelf life, but I have a drum I've used for years and it was ok when I last used it <G> Send me your snail mail address by email (despam my address) and I'll post you a litre (or whatever bottle I can find) and you can refund whatever the postage is.
