The long arm of the clamp. I needed a way to apply some linear pressure to the squares for my chess board during glue up. “C” clamps or other “twist” clamps I’m afraid will tweak the squares plus I don’t have or know of any that have the kind of reach needed.

There is a t-nut on the underside of the baseplate to accept the threaded rod. Then I screw the baseplate down to anchor the rod. Threading a wing nut applys pressure to the bar that is “hinged” by resting it on a the right in picture 1. The you get downward clamping pressure on the other end.

Works like a charm!

I haven’t started glue up on the board yet and the clamp is already coming in handy.

Thanks for looking.

Great Idea! This is one of those ideas that you slap yourself on the forehead and wonder why you haven’t thought of that years ago!

Actually, if you would put a slot in the end of the bar that presses down (or even drilling some multiple holes along the end), you would have a greater range of location without having to move your work all the time – you could shorten/lengthen the bar instead. Make sense???

Most certainly Favorited – thanks!

you can make the back end longer too if you need more clamping. yay leverage!

Thanks guys. I intend to add additional holes for the rod to add adjustment and clamping force…but my cordless drill ran out of juice and I ran out of time last night! I thought about slots but I didn’t want to reduce the stiffness of the bar. With the long leverage as in the pictures it deflects more than I thought it would. I’ll probably shorten up the reach to stiffen the bar and get a little more clamping from it when I start gluing the blocks.
