Tm Customs Posted June 22, 2004 Report Share Posted June 22, 2004 This is a great first contribution Thanks. I would like to try this stuff but it sounds epensive, if dentists use it I figure it is. I currently use fiberglass resin and Rvt sillicone, resin is cheap rvt is way too expensive. What is the pricing on this stuff and where do you buy it? Thanks, Tm PS what is the finish like on the molds? Quote Link to comment Share on other sites More sharing options...
zippomann Posted June 22, 2004 Author Report Share Posted June 22, 2004 Well I think the last time i bought some it cost me about $30.00 for 50lbs but it comes in smaller boxes were i got it my wife worked in a dentist office so you might want to talk with your dentist to see if they use the same stuff as far as the finish this stuff is a real fine powder and when it sets this has a very smooth surface i tried some on a worm once and the lettering from the worm was perfect it makes exact copys of what ever you try and do zippomann Quote Link to comment Share on other sites More sharing options...

Tm Customs Posted June 24, 2004 Report Share Posted June 24, 2004 Thanks Woodsac what have you been using to make your molds? Tm Quote Link to comment Share on other sites More sharing options...
woodsac Posted June 24, 2004 Report Share Posted June 24, 2004 I'm strictly a fiberglass resin guy. Along time ago I told people to buy it at Wal-Mart cause it was cheap. Well they were out and I didn't have enough left for what I needed. So I asked my wife to just spend the extra at the parts store while she was in town. She got it at Autozone and it was only $25 for 1 gallon! That's versus $9 per quart at wally. Something to check into if you use a lot. I got that gallon 1 week ago and it's almost gone.

vishezfish Posted July 14, 2004 Report Share Posted July 14, 2004 Hi woodsac, do make 2 part molds out of the resin? If so how!! What do you use for a release agent? And is the lure itself hard when you make the mold? I know some agents will melt a clay sculpture if it, some people use the clay that u bake so it's hard when making the mold..... Thanks!!

woodsac Posted July 14, 2004 Report Share Posted July 14, 2004 VF, No 2 part molds with resin. As it cures, it heats up from the catalyst and this causes it to shrink. I have used clay in the past. Resin is tricky. If you use a soft plastic for your mold, you risk ruining it. If not from the heat then from the glue used to hold it in place. If you bake the clay to a hard state, it's incredibly hard to remove from the mold, because it has no give. I try and just bake it enough to make it so I can still sand on it, but that it's soft enough that I can dig it out of the mold when it's done. It's a trial and error thing.

vishezfish Posted July 14, 2004 Report Share Posted July 14, 2004 Thanks woodsac, too bad, it sounds like the resin would work well in a 2 part mold... I'm going to try the rtv material and see if I like it... I been using plaster but it's time to move on.... I think u can make a 2 part mold out of this,,.... Thanks again!
