You keep repeating the same thing while apparently missing my points :)
I completely understand it is forced divided by area.
So let’s start with a simple point

”@Danny B: A pipe clamp exerts 1050 pounds of force. “

Some guy said “the average woodworker” using one of his pipe clamps could exert 1050 lbs of force on something.
IE “Further in the article, the author shows that the average woodworker can extert 1050 lbs of force with a 3/4 inch pipe clamp (which is what I’m using)”

This means, using complete and total bullshit methods, some guy came up with some idea of how much force the average woodworker could exert on a pipe clamp on some piece of wood.
Not “the maximum amount of force you can actually exert with a pipe clamp”, but some mythical average woodworker using against some mythical amount of wood.

So, then, my argument, again, is
A. that you can exert more force than this guy claims
B. Even if you couldn’t, the average woodworker stops exerting force on pipe clamps to avoid damaging wood well before they hit the maximal clamping pressure they can exert (At least, i find this to be the case).
C. The average woodworker can thus exert more of this force on the end of cambered cauls than in the middle of a piece of wood, because they won’t feel like they are about to damage the wood.

Again, I am not claiming that if you exert 14000lbs of pressure on the cauls, this will not be properly spread out and divided, and i am not claiming that you can’t exert more pressure over the smaller area.

I am instead claiming that
A. the test performed tells us nothing about the actual maximal force exerted by a pipe clamp
B. The amount of force the average woodworker exerts on pipe clamps is not the maximal force you can exert with a pipe clamp (because they don’t want to crush the wood)
C. The average woodworker could exert more force (closer to the maximal force) on the end of properly cambered cauls because they will not believe they are going to damage the wood.
