Peter, here is a couple more. I had some of the nice folks on here send me some close up images of the cam lock system and I just made it the best I could out of Walnut. It is not the best looking but it sure does lock the tripod down tight. This is the one I use for my 8x20. I still need to get a better connection from the yolk to the Majestic head. I'll get that figured out eventually.
