bassnbrad Posted August 24, 2013 Report Share Posted August 24, 2013 1st off Hi all, I know... been gone too long. 2nd off before anyone tells me to use the search on here... pppfffffftttttttt.... did that. Well I am transitioning from just painting cranks to making resin cast bodies. I am looking for rtv that I can make 1 piece molds out of that I don't need to worry about a vaccuum. A buddy out in Cali is making a mold for a top water he designed that I cleared out a master for but is running into issues with inclusions or "bubbles" the lower side. I need to find a silicone that can be poured and not have the problems with that. I also am thinking of doing up larger 8-10+" glides and want to be able to do the molds without issues. So... Here is the actual question... What would you say would be the best RTV to pour with out using a vacuum chamber that will produce the cleanest mold? Yeah Yeah Yeah Ben I know.... But I've been a bit busy as you can see... And Mark... You need more wine, cause that corks gonna get blasted! Check out the pic's, these bodies are 5"x2"x1" Any thoughts are welcome... b Quote Link to comment Share on other sites More sharing options...
nedyarb Posted August 24, 2013 Report Share Posted August 24, 2013 The lures look amazing! That's my thoughts, don't know anything about RTV silicone sorry. Quote Link to comment Share on other sites More sharing options...
RayburnGuy Posted August 24, 2013 Report Share Posted August 24, 2013 Can't help you with the silicone either, but the baits look really sweet. There's quite a few guys here at TU who make RTV molds and hopefully they'll chime in. good luck, Ben Quote Link to comment Share on other sites More sharing options...

mark poulson Posted August 26, 2013 Report Share Posted August 26, 2013 Your baits look really good!!! I used the pink silicone that Larry Dahlberg shows on his site, and it had no bubbles. But it is expensive. http://www.makelure.com/ Quote Link to comment Share on other sites More sharing options...

Mad Moose Baits Posted August 28, 2013 Report Share Posted August 28, 2013 In my limited experience with molds, Alumilite has always done me right. Quote Link to comment Share on other sites More sharing options...
philB Posted September 19, 2013 Report Share Posted September 19, 2013 Hi I use RTV with a shore rate of 18, without a vacum and it works well with no air entrapment. Phil Quote Link to comment Share on other sites More sharing options...
A-Mac Posted September 19, 2013 Report Share Posted September 19, 2013 http://www.aeromarineproducts.com/silicone-mold-making.htm I've used the purple and the "translucent" with good results. I prefer the purple more actually. You will get bubbles when mixing, but these seem to be minimal with the purple. Something that I recommend is brushing on the silicon directly onto the lure before submerging into the the rest of the batch. This will help with bubbles too.

squirrel3495 Posted February 20, 2014 Report Share Posted February 20, 2014 When making a one piece mold, I skin coat the master with RTV then hit it with heat. This will pop most of the bubbles near the master. If you let the skin coat dry some, when you fill with the rest of the RTV the bubbles that are under the master will not be able to get near the master and effect the mold. This little trick has made a big difference in the overall quality of my molds. 1 Quote Link to comment Share on other sites More sharing options...
