Wow, my head is spinning. I started reading tonight trying to figure out why my panel glue ups sometimes cup pretty badly...

Just came from reading various articles on clamp pressure for gluing up panels.
A FWW article states you will have trouble getting enough force with bar clamps... https://www.finewoodworking.com/2010...mber-of-clamps

This one says, you are probably using too much pressure: https://www.woodmagazine.com/woodwor...mping-pressure

Articles in a C. Schwarz book show a single clamp for small glue ups.

Several posts here on SMC have advice that clamping too tight causes warping.

So... which is it?
