I want to replicate a few jigs for personnal pouring and don't want to spend the $$$ on a custom aluminum mold.Is there anyone who can comment on the Hilts Perfect Replica Mold? I've also read about RTV silicone for molds but don't know where to buy it. Also heard about the Bondo technique...any suggestions on these??
Appreciated as always!

The perfect replica mold is great for copying an existing jig. you can make multiple baits on one mold and the inserts are replaceable so you can make several molds with same frame.

Can't help you with longevity, I've only done about 20-30 with mine as I don't use it that often.

But you are satisfied with it? I have been wanting a flat head recessed football mold but noone makes one so I figured I would have to make a mold for it.

I have a reply back from Hilts and they say its good for tons of pours...as long as you take care of it. Not going to be as good as aluminum but I would imagine that it would be great for me. Was just curious if anyone hear used it and what they liked/disliked about it.

How would the Hilts work for a Jig with dual weedguards?

What are the dimensions of the Hilts Perfect Replica Mold? How many jig head cavities could I fit into it?

I make my own molds out of silicone and getting a two part mold to accept dual brush guards would be very difficult. Are you talking about like the Snag proof Grabber jig? It could be done but it would need to be a mold that has two separate parts not hinged. If it were hinged, then when being opened, the base hole pins would open the holes for the brush guards. After a lot of thought, the best way to do it home made would be to have a two piece mold that instead of using aluminum brush guards, it would need to be molded with silicone that would create the holes for the dual brush guards AND be flexible enough to slide out. The large hook in that Snag Proof jig (if that is kind of what you are talking about) would be another issue because it would require a very thick mold to accommodate the voids for both hooks. But all in all probably could be done

With a single hook like that and those weed guards at those angles you could make a two part silicone mold that opens top to bottom instead of left and right and cut a section out for the hook to ride up through the top and then it could be possible(difficult), but with the hilts mold it would nearly impossible since it is not very deep.

Where I buy my RTV RUBBER for making molds is at, MICRO-MARK... I have made and used this for making molds for a long time. Anything from jigs,buzz baits and spinnerbaits. I've got hundreds of pours out of one mold and it still is not done yet by any means. Good luck... Don't be afraid to ask more guestions on how to do this with RTV if you go that route. STEVE

Time for another dumb question.
All of the RTV silicone mold making stuff I've found is rated to the mid 400 degree fahrenheit temp. range, but lead melts at 600+.
How is it that molten lead doesn't ruin the RTV molds?
Posted 17 February 2012 - 05:29 AM
I don't know, but the lead doesn't seem to hurt it. I keep my lead at about 750 to 840 degrees and pour into several RTV molds and have never seen any damage to the RTV.
I spin cast into vulcanized silicone molds everyday and a mold lasts a long time. If it is 3/4 oz you might get 1000 to 2000 pours at 10 parts per mold. That's 10 to 20 thousand parts and then the mold is still not in bad shape. It will have a small parting line and then where it breaks off it will have spot similar to what it looks like when you hand pour. A mold for small jigs, 1/32. would do a lot more.
You ever notice when lead splashes on the table or you hand how the lead "freezes" pretty quick? A metallurgist told me once that lead didn't have as much thermal energy like say for instance molten steel, Get a little piece of hot steel on you arm when you are welding or using a cutting torch and you feel the difference

I use rhodorosil v340 with the ca45 catalyst, you can get it from Jim at Sunbelt Materials. He is a great guy to deal with.

I use Sculpey Clay to make my soft plastic masters, and I want to use it for my jig masters, too. Will that RTV work with Sculpey Clay?

I use this.

Thanks again dlaery for directing me this way, stuff is great. Now I almost like making molds as much as pouring lead!
