My personal clamps are all either wall mounted or on the end of my assembly bench, the big ones anyway. (Bessey K-body) The smaller F clamps are in the bottom drawer of the black tool chest/cart.
There is a rolling cart with pipe clamps, that belongs to the company. It has something like 20, that range from 30" to 60". There are a half dozen 10' pipe clamps, leaning against a corner. They don't get used very often, but darn handy when needed.
The extra depth of the K-body jaws works out well when clamping across the pipe clamps, so I do use them occasionally.
[member=57948]ChuckS[/member], you really find those aluminum bar clamps to be stiff enough to use?
I have always considered "aluminum bar clamp" to be an oxymoron. No such thing.
All of the ones I have tested were so flexy as to be unusable.
I wouldn't mind having a few lighter clamps, if they are worth using.
