RTV molds / Resin cast

[Rowhunter]

I made these lips from polycarbonate sheet 5/64". I'll draw up and cut out many different shapes and sizes and test them to get desired results. I'll use a thicker polycarbonate on much larger trolling lures, as well as stainless and G-10 phenolic.

Remember this is just a quick insight, there are a lot of specifics if you'd like to check this out. With the ratio of resin to microballoon mixture it is possible to achieve density similar to balsa all the way to sinking. So, if you have a plug that you make out of say, Maple or Birch, it would be possible to dial in that mixture, and not have to worry about water intrusion. Painting, not yet! One thing you have to deal with is "off-gassing". The best way to be safe here is to set them aside for about 3 weeks. If you begin priming right away you may have adhesion issues. Also, you most likely have some small pinholes in your casting. If you wish you can fill those with spot filler and lightly sand. I know many of you paint with Creatix or similar, I've been told that Krylon Fusion is a great adhesion promoting primer between the resin and those paints. I use automotive paints so I shoot an adhesion promoter, primer, then start with base coats.

Nebe, 20 at a time, you were a glutton for punishment, I'd like to see that mold. And yes, thats a great idea of locking the lips in place if I was only doing that one lip type. Thats the nice part of all of this is that there so many different possibilities.
Ec you are seeing it right. The one with the long lip is not a true thru-wire. The lip and wire tie are epoxied in as an assembly. The belly and tail hook attachment are molded in with the ballast. Yes, this is another avenue of possibilities and especially nice for duplicating pieces that have intricate carving.
Painting, I'm planing on starting another thread to throw some things out there.

Rowhunter, my eels were soft plastic, so i would simply pour a bunch at a time- once they were demoulded, they were done.. no painting..


are you making your own decals?? im assuming that is how your achieving your colors

I for one can't thank you enough for posting the process, it's something I have considered but have yet to do the research.
Thanks!

Nebe, soft plastics that makes sense. Decals? No, all of what you see is just airbrushing.
