Hi Everyone:
Not sure if this is exactly on topic, but it's close... one of my C-stand hooks that I made. (Taking a few years off soundwork to be a blacksmith does have it's advantages, after all). It's made of 3/8" solid round stock, bent, welded, and painted. A little clear vinyl hose for some padding. I made these a little bit longer than the ones you can buy, it's a little gentler on the boom... a touch less leverage at the contact points.
