Two Piece RTV Jig Molds?

[mitrisin]

Anyone ever make any two piece RTV jig molds. If so, how do you make it so the mold halves are even enough to fit the hooks properly? I want to mold a custom jighead but at low quantities so I think RTV would work.

I'm not real sure how exact you would have to be, because I'd think it would be far more forgiving. If I remember right US Composites should be able to help. Maybe Lurecraft also, seems there's somebody who sells RTV by the pound and shows you how to make molds

I have never made an rtv mold but i have made silicone molds that vulcanize in the oven using silicon sheets, same ones spincasters use. I use a aluminum frame similar to a jewelry frame but with bolt holes and side plates, 2 1/4 sheets of silicone then a little mica powder then you master and then 2 more sheets. compress and heat and its done. Hard to get the silicone though

Some where in all the files on one of my computers I have a few files that were sent to me by Some one that had made a few of them. I have tried to find them and when I do I will post them for you. Sorry lately I have been as busy as a one arm paper hanger.
