Have seen many videos on YouTube showing how to make home made ovens to melt down metals. Has anyone done this? Iv thought about it because i have tons of brass fittings with built in sensors from cars. Some are chunky and the sensors/other metal bits would decrease value would it not?

I have the resources to build one, and all the time in the world to melt stuff down. Saturday afternoon "bonfire" anyone?

All joking aside, has anyone done this or thought about it? Or am I just over ambitious...LOL
