Epoxy Tip
I learned this when building rods-
mix your epoxy on a sheet of glass and then heat if from below to decrease the viscosity and let the air bubbles escape. Hardened epoxy easily scrapes off with a razor blade and the glass can be used over and over.
Bonus- because the epoxy is spread out the heat released by the exothermic reaction between the resin and the hardener will dissipate and give you a longer pot life than if it were in a cup.
