Thanks to all that replied. I went home and tried to tighten the clamps with the tool from my other Bogen (the one that slides didn't come with it). This seemed promising at first, and a silly oversight on my part... but unfortunately it didn't work (not yet anyway).
The little rinky-dink tool bent each time before any of the nuts even budged. And as of now, the legs still slide. But Lon mentioned: > I'm sure a standard socket set has the > appropriate socket. I guess that's what I'll have to look for. Or some kind of power tool that'll fit in there. Well, thanks again. At least I know that all is not lost with my 3036, and I know what I need to look for. - jerome
