Build an Epoxy Mold

Creating custom resin molds opens the door to endless woodworking and maker possibilities, and in this video George shows just how easy the process can be. Instead of relying on expensive, pre‑made epoxy molds that never seem to be the right size or shape, he demonstrates how to build your own using simple construction‑grade plywood and a clever joinery method that makes assembly and disassembly fast and frustration‑free. Whether you’re turning bowls, making knife scales, or casting hybrid blanks for other projects, this approach gives you total control over your mold dimensions and design.

You’ll also see how a specialty mold‑lining product transforms the process. No release agents, no messy sprays, no wrestling with stuck resin — just a clean, reliable release every time. Combined with a smart trick for keeping wood blocks perfectly positioned inside the mold (so they don’t float, drift, or tip during the pour), this method produces consistent, professional‑quality blanks with minimal fuss.
