I wouldn,t go to crazy buying molds till you try doing this first, its not as easy as it sounds and its hard to get a good pour on these molds and you,ll have lots of figures that didn,t come out right with missing arms legs ect. and also lots of flash to trim off.
Some molds pour better then others and the first couple of pours don,t seem to work till the mold heats up. Its a lot more work then you think so just try a mold or two and see what happens.
Maybe some of the forum members here could give you a few tips as to which moulds work better and what metal to use but I tried a prince augastine napoleonic mould and a britains detail knock off mould and didn,t like the results and gave up.
I hope you have better luck then me. I think I,d better stick to making my lead fishing sinkers!!!
Maybe I should have tried using some other metal then lead??? but the price of the lead was real good!!!(free)
Again I wish you the best of luck, let me know how you make out and if you make out good you can let me know what I was doing wrong!!!
