Bar clamps shouldn't be "light duty". They didn't bend. The damned
thins broke, with just moderate pressure. My Irwin Quick Clamps will
do 10x the clamping force. ...and they aren't designed for such.

I hate to say this, but if your joints were made better, you would not
need so much force. If you have to jam them together, something is wrong
with the joint.

It rather depends upon what you are gluing up. If it is a 42" x 96"
tabletop I suspect you will find that the edges are not perfect and need
some force to close.
