RiverMan Posted December 23, 2003 Report Share Posted December 23, 2003 I have no idea how it happened but I just ruined my favorite RTV plug mold. I had some featherlite that was too thick to pour (it was cold) and tried to wipe it out of the mold. I then washed the mold in warm water and then reapplied petroleum jelly like I always do. Poured in the featherlite and when it had dried...stuck tight! I am really bummed as the mold cranked out the most beautiful reproductions of my favorite crank and was in perfect condition. Well, time to buy some more RTV, any suggestions on where to buy, been a long time since I ordered some. jed Quote Link to comment Share on other sites More sharing options...
Mattlures Posted December 23, 2003 Report Share Posted December 23, 2003 I did the same thing with featherlite. I mixed both cans well than mixed together and that crap never cured! thenwhen i tried to clean it out it stuck to the mold. Is there any other products out there that float? you can get inexspensive rtv through smooth-on also Quote Link to comment Share on other sites More sharing options...
Art Brush Posted December 23, 2003 Report Share Posted December 23, 2003 Hi fellas, rtv can be purchased from http://www.smooth-on.com. I recommend the moldmax 30. It has performed well and I've only had 1 mold go bad after casting crystal sheen in it. Featherlite parts A & B tend to separate as soon as you stop mixing them. I never mix more than a dixie cups worth at a time. I Thouroughly mix A & B before mixing them together. When I feel the plastic start to warm in the cup I cast it into the mold. Also to extend the life of the mold use a mold release agent. Vaseline or WD40 work well. You can also make backups of your rtv molds by building a mold box around the mold and casting a hard plastic into the box. Then you can cast rtv into the hard plastic master mold without having to reclay your prototypes Shawn Quote Link to comment Share on other sites More sharing options...
RiverMan Posted December 23, 2003 Author Report Share Posted December 23, 2003 That is an interesting idea Shawn, had not thought of that. More than the cost of the RTV what I hate to lose is the time it takes to rebuild the mold. I love making the baits, hate making the molds....I guess we probably all do. I wish too that we could find a reasonably priced RTV, the stuff works great but is certainly spendy. Have you ever had any luck using plaster with the featherlite? I have become very comfortable building two-part plaster molds over the years but when I have poured them with featherlite in the past they have always chipped on me. Regular silicone molds like the stuff you buy at the hardware store causes some type of chemical reaction that won't let the featherlite set-up which pretty much brings me back to the RTV. Guess I took a long way around the barn on that huh. Jed Quote Link to comment Share on other sites More sharing options...
Art Brush Posted December 24, 2003 Report Share Posted December 24, 2003 Jed, I havent tried featherlite in plaster molds. I've tried epoxyputty pushed into the plaster to create a 3inch holo bait but the putty has to be thin to make them float. 12grams to be exact. lol They are far too brittle to fish with. Pretty potatoe chips KrUnChH! :oops: Shawn Quote Link to comment Share on other sites More sharing options...
