I pour my own baits but I do not sale them. They are for personal use only and give a few away while I am on the lake. I like aluminum molds but they are not always cost effective unless you pour alot of baits. I have some stone molds and although you have to prep them before use, they work fine for me. My question is why are there no American companies making stone molds. Looks like Russia and Romania are the only countries who produce them. I'm guessing they use the same CNC machines we use here. Seems to me there would be a healthy market for them here. Anyone know the reason why we don't produce them here.
