jigginpig Posted April 19, 2015 Report Share Posted April 19, 2015 I was wondering if casting resin such as Smooth Cast would bond with a quantity of itself that had already cured? My idea was to pour a small amount of the resin "full strength" or un-cut with additives into the bottom of a mold, allow it to cure, then top off the mold with resin containing micro-balloons. This would (in theory) allow a bait to be self-ballasting, without the need to drill holes or dicker with positioning ballast. I want to make a mold of a walking topwater (like a Sammy with a deeper cupped face) but I understand casting resin is ill-tempered when it comes to that type of bait. I guess while I am at it, has anyone built a good walking-type topwater with casting resin? All the good ones I am aware of are injection molded in two pieces and assembled with glue or carved from wood. I put a fair amount of detail in the master, and it would suck to lose it. Cheers all.

Long Lake Lures Posted April 19, 2015 Report Share Posted April 19, 2015 Smooth cast 300 will bond to itself, but I am not sure how the microballoons will affect this. Quote Link to comment Share on other sites More sharing options...
Jdeee Posted April 20, 2015 Report Share Posted April 20, 2015 That should work. There was a thread about two months ago using smoothon foam on top of regular smoothon resin to give ballast. I have used this method for a couple of years and never had a problem with the two resins sticking together so I don't think you will have a problem at all. It will take time to find the exact mixes but a little trial and error and you should be good. Quote Link to comment Share on other sites More sharing options...
FrogAddict Posted April 23, 2015 Report Share Posted April 23, 2015 Jigginpig, I've been casting sexy dawgs using alumilite for awhile now. I use micro balloons in the mix and put some ballast toward the tail because I want them to sit almost vertical while at rest. I haven't felt the need to do what you r suggesting yet.

SS If you're worried about messing up your master, make a good silicone mold of it. The money you spend on the mold making silicone will be worth it if your master is preserved. Smoothon makes lots of silicone mold making products. I don't know which one is best for you, but someone here will. Quote Link to comment Share on other sites More sharing options...
jigginpig Posted April 24, 2015 Author Report Share Posted April 24, 2015 Ha ha thanks Mark, but I was just alluding to the fact that if I was to use it to go fish with, I could lose it. The platinum cure RTV Smooth on makes is great, I have had good results with it for hard-bait molds. Quote Link to comment Share on other sites More sharing options...
