So I am finally getting to the stuff I am really wanted to make with my Primo, molds for soft plastic fishing lures. But I am not starting with aluminum, for now I am going to use Corian. As close as the lure making forums can tell it’s viable there is even companies making “Stone” molds commercially and as far as anyone can tell the “stone” is Corian.
As I understand it it should behave like acrylic so single flute cutters and speeds that don’t melt the plastic back into the cut. But I am a noob so any pointers are welcome.
