Hey all. I just got some 50" Bessey K-Clamps online. I chose Bessey since they seem to be better liked than the Jorgensen Cabinetmaster and I'm surprised to see that there's quite a bit of flex in the bar when you press on it. I know that during a glue up the pressure is applied evenly across the bar so flex probably won't cause the bar to bow but even a slight bow is a problem.
I know that steel bar clamps won't flex but then you don't have pads that clamp perpendicular to the bar and you don't have the nice wide pad.
Anyone else have concern over this flexing? Any wisdom will be appreciated.
Thx
Michael
