It was either Christmas or a birthday several years ago that my youngest sister bought me the Harbor Freight powder coat machine. I immediately jumped on Craigslist and found a free 220V oven. I made sure the oven worked but I never opened the powder coat until yesterday. I plan to build a legit oven from the components of the CL score. I wanted to test some scraps to see how it lays down and cures. First lesson- use the powder containers that come with the machine! At a glance I thought the new red from Harbor Freight had the same threads, it didn't screw in perfect and it fell off the gun spilling about half all over my garage floor. After cleaning up I was able to get a few pieces of scrap painted. Not perfect paint jobs but I wasn't expecting that on first go. I'll keep practicing. I'll certainly post progress with the new, large oven.
