I built this target to take to the Renaissance Festival I participated in last weekend.  I figured the people would like the cymbal.  And it worked out really well.

Here's the build and a quick test.

Thank you, Joe! Great video! Yes, I also made a target with a plate on a wooden cylinder. The video clearly shows that my problem is with the cheap iron disc — mine is very thin, unlike yours. That’s why I have such a terrible sound)). Many thanks for the detailed video!!! Sometimes it’s very difficult to determine the boundary between Diana and Quadro, even when watching a slow‑motion video. So this target is a great option for tournaments and competitions.
