Whenever I've tried gluing up things in the pipe clamps I have, they want to bow up. Two boards together and the tendency of the clamps seems to make things go kitty-wampus, and the more pressure, the more dramatic it is. If 3 or more boards are together it just gets even more dramatic.
I set the clamps facing up and lay the work right on the black pipe so its flat and level. It seems good until there is pressure applied. I put a 25lb cast weight on the work sometimes to help keep downward pressure.

I know this might be a dumb question for the veterans here, but I need to get better at this.

Maybe a you tube video search.

These look like they wood work.

Don't have much experience with it, but I've seen people use the pipe or bar clamps by alternating the clamps topside and bottomside of the panels to even it out.

I think many folks use boards, called cauls, on either side of the work pieces clamped together to hold the work straight. I found this sight when I googled.

Pipe clamps seem go have inaccurate angles on the clamping faces.

The ss clamps are convex across the length similar to cauls.

You can easily make some cauls yourself.
