Welcome to "How to Build a Powder Coating Oven - Part II." See How to Build a Powder Coating Oven Part 1. In part 1, we build the oven frame, we started skinning it in sheet metal, we added lights and the convection blower, and also insulation and heating elements. I am going to pick up right were we left off. This powder coating oven build was done by KNJ Custom Coating and I want to thank them for contributing all of the information and pictures.
