Well i have used the janns injector for a while and just now switched off of it. It is not a very good injector and its cheap and doesnt hold up long. I have an injector that would fit his molds that my dad made but that is custom i have no idea how anyone could buy one to fit that type of mold. I do hear of alot of people using glue guns to make plastics around here, maybe he makes them for that. It seems to me he is making them and selling them because he has a site where he sells them directly too. I dont think ill ever buy from him his molds dont look that great to me and he is pricey. He probably has a cnc machine he has access to and came up with a couple designs. I tried to see if he had a store but he doesnt he his all online based but i may be able to meet him sometime
here is his site http://www.jacobsbaits.com/
