Here's a tip that just saved me from investing in a new tripod head: I have a Manfrotto 410 compact gear head for a couple of years. The tightness wa s always a little marginal with my Toyo CX, but recently it became a little too loose. I made a small hole in the center of each of the three circular joints and lo an d behold there was a hex bolt just waiting for an Allen key. To tighten the who le head to a condition better than when I bought it took about one minute. Thanks to everyone for all their help. It's nice to be able to give back.
