Have an old palmgren table:

It binds up when I clamp something to it using the "T" slots and finger
clamps. It's better if I don't tighten the clamps much.

Apart from the obvious is there any way to keep the top from warping?

Hi, Terry.
I am surprised at the table warping enough to cause problems. Have you
determined how much clamp force it takes to notice the binding? I was
going to suggest you check for a cracked table, but the unit in the
picture looks so clean, you could easily spot a crack. However, just
to be sure, see if you can gather some iron/steel filings and use them
and a big magnet to see if you can spot any cracks in the "T" slots.

How recently have you disassembled the table to clean it? Another
possibility is the lock is hanging up.

I have a very used rotary table that has a broken outer corner of one
"T" slot and I didn't do it, so I know that sometimes they get over
torqued!

Let us know what you find.
