even large manufacturers this process would suck. Pie molds in general suck layed out round. I built a pie mold last fall, and laid it out square and got 60 cavities, were i could get 30 in round orientation. and it only takes 65-80 seconds to cycle were i don't have to spin, etc. Spin cast works in lead so well, because of its weight. and you can force it in tight spaces faster then it can cool. With a cooled mold and the same number of cavities he has in the video, Dave Mc could have shot 2x the baits with glitter and salt, laminated in the same time frame.
