Giant Clamp [Restoration + Force Test]

This clamp was apparently used to glue large wooden beams together Based on some of the features, I think this.


This clamp was apparently used to glue large wooden beams together Based on some of the features, I think this was made no lather than the 1940s Please let me know if you have seen anything like this before Needle scaler This part looks hand-forged Looks like it was welded… I wonder why this mark is here… Removing some large high spots I am going to smooth out the sides Danish oil I am going to test the clamping force with load cells Using voltage to calculate force Maxed out the load cell, switching to larger one 1lb of force=voltage x 663.5, for this load cell 20,170 lbs of clamping force I do not want to test the force until it breaks… It deformed the load cell bearing!

  1. Geez, sure could'a used a kid like you back when I was building stuff for shows out in Alberta… but, sadly you would just turn into a jaded old cuss like me!
    Just kidding, you're doing a great job and good editing to boot!

  2. Why don't you donate a couple to the local hospital. I'm sure they can find a use for them in the operating theater. Hip realignment for droopy but toks – what are 'but toks' ? Americans have them you know, sounds awfully painful.

    Gracias y un abrazo, desde El Puerto de Sta María

  4. I am sure you will all be delighted to learn that I have never seen one of those. Waiting for applause to die down. Thank you. Thank you very much. I know how important it is to tell you I am stupid.

  5. When I was a young man ,40 plus years ago.
    I was hired to cleanup every evening for a lumber and truss company , there was several of these mounted on cribbage in the old open building where junk collected. I NEVER saw these in use and had no idea what the were used for ? At that point they had been a family business for more than a hundred years. They were famous for providing much of timber for the rail road, train stations !

  6. I love your videos.
    I think you should have used molybdenum grease for the thread and 'foot' though. Moly grease is able to resist the compressive forces much more than oil owing to its film strength.

  7. I was going to leave a comment about the amazing almost “foley like” sound quality of these videos, but there are already 977 comments

  8. Me: Why the hell would you need a clamp that-
    HTR: THIS CLAMP WAS APPARENTLY USED TO GLUE LARGE WOODEN BEAMS TOGETHER
    Me: Well, I guess that answered my question.
