The answer? Build a giant, modular, 110V composite curing oven that fits an 8-foot-long cowling mold, can precisely control ramp rates and dwell temps, and might even get hot enough for future powder coating projects. In this video, I’ll walk you through: ✅ Why I needed this oven in the first place ✅ The key design constraints (like safety, cost, and 110V power) ✅ A full materials and electronics breakdown ✅ The entire construction process ✅ A first test — with actual heat and no house fires! If you like DIY builds that are a little unhinged but fully functional, subscribe for more garage-based chaos. I’ve got a helicopter to finish building — and this is just one more piece of the puzzle. #HelicopterBuild #ExperimentalAircraft #Composites #TheOkayestEngineer PID Controller https://a.co/d/hPFmxBz Thermocouple https://a.co/d/eTJ5ARu Relay https://a.co/d/dTW7qCd Relay Heat Sink https://a.co/d/hUkvwRV Heating Element https://a.co/d/dZxg2Fr Fan https://a.co/d/82Hxjnv Electrical Box https://a.co/d/esmj5jo R15 Insulation https://www.homedepot.com/p/Owens-Cor...
