WallsOut Posted June 4, 2004 Report Share Posted June 4, 2004 I've been making plaster molds for several months now and have been fairly pleased with the results. I have a couple of questions. I've searched the archives and it couldn't find what I was looking for. 1. What kind of glue do you guys use to glue your baits down with? I've used Elmers and it seems to thick, you get alot of runnoff on the sides. Also I've used crazy glue and seems like I had a lot of plaster under the plastic. Also they were permanetly stuck to the container leaving the containers useless. 2. I read that someone was using a sprayon adhesive is this a good idea? 3. I would like to make a mother mold. Is it possible to coat the plastics with some sort of thin liquid that will permanetly cure the plastic to the container and I will get identical molds all the time? Thank you guys for taking the time to read this and for any possible answers I may recieve. Eric Quote Link to comment Share on other sites More sharing options...
Art Brush Posted June 4, 2004 Report Share Posted June 4, 2004 Eric, 3. I would like to make a mother mold. Is it possible to coat the plastics with some sort of thin liquid that will permanetly cure the plastic to the container and I will get identical molds all the time? The best method I've found thus far for making a "Mother mold" or master mold is to make a mold of the mold. Take your best mold and lay it face up on a hard plastic surface. Build a box around the 4 side of the mold with approximatley 1/4 inch space all the way around. Seal the edges and base of the mold box using non-hardening wax based clay. You can find it at Xmart in the kids craft section. Being that your molds are made of rigid plaster the mother mold should be made of a pliable material. RTV silicone works well. Pour the silicone into the mold box untill it covers your original mold by about 1/4th inch. If you want to make a master mold of an RTV mold use a rigid material such as fiberglass resin following the same process as above. With fiberglass resign you will need to put some liquid dish soap on the plastic base to keep it from sticking. Allow the dish soap to dry before casting the resin.

Big Splash Posted June 4, 2004 Report Share Posted June 4, 2004 I copy a mold like Shawn does, but I use worm plastic insted of rtv. Build the dam around the mold as stated above, then pour the plastic over the whole surface of the mold 'till it is 1/4" deep over the top of the original. You can keep the master handy to make up new molds any time you need one. Quote Link to comment Share on other sites More sharing options...
WallsOut Posted June 5, 2004 Author Report Share Posted June 5, 2004 Thanks Guys. Those are some pretty good ideas. I'll have to try that out when I get some perfect molds. Eric Quote Link to comment Share on other sites More sharing options...
