So i been pouring my own lead weights amd jig heads, and tying crappie jigs for a while. Just orders a bunch of stuff to pour plastics, or try. I added in to my workbench in the basement to add room fro microwave and all that. I got the pyrex cups, microwave, and everything i think ill need. Does anyone have any advice to offer? Any dos or donts i should know before i start? I do have one question. The molds i have seen, looks like you inject the plastic into it, where does the air go thats in the mold cavity? Id think it would have to have and exit or vent and one would pour till it came out or something. Or im thinkin too much lol
