I didnt make the shotmaker, but play around with different size orifices. Dont know the brand of it, bought it used. An inclined shelf with internal element, big enough to hold a couple ingots, brass orifices like for furnaces in the front to drip. Made an inclined shelf which I chalk, with cold bowl of recycled vac pump oil underneath to catch the shot and cool it before it hits the bottom and deforms. The trick is to have the oil cold enough, the lead at just the right temp, and the inclined shelf long enough to round out the shot nice, especially for the larger sizes shot.
Orifice blanks are cheap and can be twist drilled to whatever size you want. Orifice blanks at your local Johnstones Heating supply, and powdered chalk thats used for chalk lines.
Wash the oil off the shot, spread thin outside to dry. Lightly chalk if desired.
