Inspired by lumberjock Dave Rutan. Thanks Dave! I made these clamps from scrap pine and plywood.
I also made the handles a bit over-sized for a better grip and added a nut to the end for a wrench during the times I need some extra clamping pressure.

Great job of jumping on these. i just put it in my favorites! They look like a great way to get some quality clamps.

-- Robert, so much inspiration here, and so little time!

have you determined the maximum clamping pressure they can withstand? it looks like a great idea, just wondering how durable they are and how long they would last under pressure

Mac, I have not tested the pressure. I can tell you I put as much force as my hands could put on them and they did not crack. The hard wood I was clamping left a slight indentation in the clamp, but I expected that.

I did notice however that when I reached the max pressure my hands could handle, there was some movement in places where if I were to add wrenching pressure their might be problems. I think I may have this solved, in my head at least. Gona have to build some more with the mods I have in mind and then test that way.

My goal is to build them as cheaply as possible. Otherwise I might as well sell my dog and get my youngins to start washing cars so I can afford ONE bessy clamp. Just joking….but not really.

arangov3, No I have not made any updated ones as of yet. There were two mods I had in mind.

1. Move the threaded rod closer to the shaft or “bar” part of the clamp. I did break one clamp while clamping. As I turned the rod I noticed the bottom part of the jaw would stop moving while the top kept inching forward which eventually broke the jaw due to the severe angle. I think by moving the rod closer to the shaft of the clamp it will have more contact with a solid surface no matter what the thickness of material I am working with.

2. This is an easy one. Just add more holes in the shaft so I can have finer adjustments with the back jaw.

I have used these clamps many times and with the exception of one they have been great! The best part of the clamp is how they dont tip over when trying to clamp your work piece.

Hope this helps. Good Luck.
