Binoculars Clamp arrived

A good news is the binoculars clamp I ordered on-line arrived today via UPS. It's nice and strong. A bad news is the thread hole at the bottom of the clamp is 1/4", which doesn't fit 3/8" thread screw on the base. So I need to use the mini-ball head that is dual-threaded to fit either size, which is heavy itself. The weight of the ball head and the clamp combined is 1.14lb (851g) total. It's quite heavy to walk around with while looking for the best spot to paint. I might look for a lighter ball head with 1/4" thread screw. But I'll wait at least until I build a stretched canvas holder. The clamp hasn't come cheap since only kind I found, then got, was from the same Manfrotto made in Italy. I found an used one though. I don't want to spend much more until I'm sure this system I'm thinking now would really work.
