I have about 40 pounds of old scrap pewter. Dented mugs, bent up candle sticks, etc. Paid little or nothing for it. I used to melt it down into ingots and sell it for those who wanted pewter nose caps on half stock rifles. I just picked up a spinning lathe and I need pewter sheet discs for spinning. If I make a mold for a flat disc, say 1/32 by 6 inch diameter, will that work for spinning?
