This is just a short video that covers some of the different materials you can use to make a resin casting mold to pour your Alumilite, PR, Epoxy, etc. in. In the video I mention Brendan Stemp's YouTube channel, so go and check out his videos as well. He does some amazing turning, but I really love his creativity and use of resins in his work. The kind of stuff I love doing! Also, you can get the silicone molds from Fred Wissen. He sells lots of pen blanks, supplies, and of course tube-in casting molds. Check out his website for more info: http://www.ptownsubbie.com/ I love getting feedback and helping others out, so leave a comment for me. Good luck, and get casting!
