I have been playing with spinning my own resonator cones on my lathe. I have had good luck with paint can lids and have tried copper, with some success. Copper has a steeper learning curve. If you have a lathe and want to try it, I have a video I was going to post in the video section, but the file was too large. It is posted on YouTube and shows how I made the paint can lid resonators, including the wooden form and homemade wooden tool.. Let me know if you try it! Thanks!
