In this episode of The Okayest Engineer, I set out to solve a very niche problem: how do you cure full-sized carbon fiber helicopter parts at home without burning your house down?

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.
