Thanks for the reply.

I would say it starts to bind at about half the torque I would put on a
clamp that was used on the main table, I'd definately like to tighten it
some more as I had a piece move on me tonight.

I've just taken it completely apart and cleaned, inspected and re-assembled
it, it's in great shape...


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.
