Clamps Loosening Problem
 

Hi. I've have a little clamping problem that someone may have a
solution.

I've got four Jorgenson standard fast acting clamps like the ones in
the following link.
http://www.leevalley.com/en/Wood/pag...850,44647&ap=1

All four of these clamps (some more than others) loosen up quite a bit
over several hours (certainly less than a day).

I was wondering if there was some product that I could apply to the
clamp threads that might decrease this slippage?

I know about Loctite and its various levels of formulation, but I'm
not really sure that is the type of product I'm seeking. Anybody have
any ideas?

Thanks

I have had that problem and Jorgenson gave me the solution. I was
extremely skeptical but I did what they told me to do and the problem
went away.

"Thoroughly" wire brush the threads on the clamping screw.

You want the threads clean and dry, no lube. What makes them slip is
tiny particles of dust that gets embedded in the bottoms of the threads,
be that wood dust or rust dust.

That's good info.

I was going to suggest acetone, thinking it was lube, not the dust.

BTW if the op is using it to hold while chopping , the type of table
matters too. I had used some hand screws and every time I hit the chisel
they loosened. Turns out it was my old workbench, it was a solid core
door and it was bouncing so much it caused it.

Thanks, I'll give that a try ~ after I locate my wire brush.

Mine was a wheel mounted on one side of my bench grinder.

Always knew where it was.

Then if you ever forget where it is, you'll know it's time to visit
the Alzheimer's doctors.

I suspect you have the adjustable clamp to close to the wood
and therefore the angle is shallow. You want more angle and distance
from the wood allowing the screw to press the orange bar sideways and
then the metal slices cut into the bar not slide.

I have used these in both flat bar and long pipe bars. The only problem
I have had was using (what I could get) galvanized pipe - use black iron
pipe for the proper clamps.
