Mad Moose Baits Posted April 8, 2018 Report Share Posted April 8, 2018 OK, I am modifying some heads to accept a wire form and then will be making a spin mold from them. I will drill into the lead head and put the wire in it. I could epoxy the wire into place, but I worry the heat during vulcanization will soften it. Would a solder paste work? I figure I could hit it quickly with a torch or even a heat gun. As always, I welcome advice and suggestions! Quote Link to comment Share on other sites More sharing options...
Mad Moose Baits Posted April 8, 2018 Author Report Share Posted April 8, 2018 May also consider JB Weld High Heat putty, but it may be hard to get it in a small hole (1/16th") and such... Quote Link to comment Share on other sites More sharing options...
reeves Posted April 8, 2018 Report Share Posted April 8, 2018 I wouldn't worry about the heat bothering the epoxy during vulcanization. I use an epoxy all the time on my master models and have never had a problem. Occasionally, if it is a thin layer of epoxy, it may peel off the master part after it is removed from the vulcanized mold, but at that point it has served it's purpose. If you are thinking that the epoxy is going to lose it's shape or holding power during the vulcanization process, don't worry. Once the mold halves are together in the mold frame and pressure and heat applied, the rubber is encasing the master part and nothing is going to change shape. In your case you are affixing a wire inside a lure body epoxy and it will not be exposed to the rubber anyway. A word of caution. Some things like super glue are not compatible to silicone rubber and the rubber that touches a surface that has super glue on it will not vulcanize. This could be true with the epoxy you may use. 1 Quote Link to comment Share on other sites More sharing options...
Mad Moose Baits Posted April 9, 2018 Author Report Share Posted April 9, 2018 The epoxy will indeed be inside the body so this should work well. Really appreciate the reply! Quote Link to comment Share on other sites More sharing options...
