the clamping issue is one area id like to see all mold makers agree on. i have a guy working on a jig for all of my plug craw molds to sit in so that they are sitting with 1 corner up like a diamond but i am going to have to true another side as the bottom is already true/flush the way it was explained to me was that there will be some sort of like clamp bar to squeeze the molds to gether. i like this site when we can all work towards an idea and make ALL products better!! as for your grub molds jim as little amount of plastic as they take if you could line 10 down a side with a center runner to feed all 20 baits you could probably run 5 with someone to help you demold and never stop shooting molds..are you looking at something like a fat albert or a kalins grub? id really be interested in something like those as well, my bobs molds just throw out so many defective baits i hate using them!!
