Three Pin Lewis Demonstration

  • A three pin lewis, also known as a dovetailed lewis, St Peter's keys, or a Wilson bolt fits into a dovetailed seating in the top of a building stone. It is made from three pieces of rectangular-section steel held together with a shackle, allowing connection to a lifting hook. The middle leg is square throughout its length, while the outer legs are thinner at the top, flaring towards the bottom. Held together, the three legs thus form a dovetail shape.
    They are now illegal in the UK but were still in use when I started my career.

      It's illegal to use because it's not that safe.
      A MASTER, as this guy probably was, knows what he's doing.
      But someone less skilled only has to cut the hole slightly wrong and it will fall out. or if the stone is bad, the force wil fracture it, and it will fall out.
      You need something that works, even if the guy doing it is clueless.
      And when you're lifting multi ton stones, yeah, you wanna get it right.

    I have worked with old stone masons who didn’t have power tools, and I have helped them to build a couple of private mausoleums. They were 8” thick granite walls 8’x10’ they called that device a German key. The Lewis pins we use are single angled apposing holes. Sometimes as many as three mostly two. And the type of steel they are made of now makes them very expensive but they work great,because you can’t use straps when setting walls. And also the pinned stone clamp works too and cheaper.

      Do you cut a keystone shape in the stone, with the bottom wider? The 3 pieces fit too loosely to think otherwise, not that it needs to be a tight fit in either dimension.

  • @peterblacklin9174
    @peterblacklin9174 Před měsícem +62

    They allow a stone to be positioned or fitted into a slot where other lifting systems would get in the way. The quality of the stone is important as the device puts the block in tension (splitting). My opinion, for what it's worth, is from basic mechanical engineering and dry stone wall building experience.

      I guess the safety question is 'how often does this fail?' causing a large heavy stone to fall with a lot of potential for damage. As well as whether this could compromise the internal strength of some stones (1 or a few in a wall?) which could cause a lack of expected structural strength.

      If the stone had an unknown fault, and we're talking much bigger stones being lifted way up in the air, it could let go while being moved and fall to the ground killing whoever was unfortunate enough to be under it, or possibly doing some serious damage to infrastructure. It was a system that didn't have any backup if it failed. These days we can add multiple chains and / or straps to something being lifted.
      Also the process of adding the holes it needed to install it, could cause damage to the stone you didn't want in the finished product.

    So, this is a very clever design, but I think an explanation is in order, an explanation of why this device is better than simply putting ropes around a stone. Is it because this device allows a stone to be placed very precisely where it's going, so builders don't need to deal with any movement or instability at height? Ropes seem like they'd save time, but maybe removing them up high is more risky?

  • @ShinyAnvil
    @ShinyAnvil Před 27 dny +4

    Apart from this time consuming method there is a way simpler one. (Not to mention that this method has the potential to split the stone.)
    Almost all of the stones in gothic cathedrals have 2 or 4 small holes on both sides and they were hoisted up with a simple claw very similar to 20th century ice block claws. The larger the weight of the stones, the tighter the claw grips compressing it.

      The first I learned of this was observing Segovia aqueduct back in 1996, and noticing all those holes and surmising they might have been for lifting. I had to look them up later. No internet for me then.

    I don't have much experience with historical (or any) stonework, but at first glance, this seems like an awful lot of work just for the purpose of lifting the stone. Why not use a simpler method, like the self-locking claw things, for example? Cool technique, though.

      They probably provide a more secure hold on the block. I've seen several of these holes in stone mines in Wiltshire. They're an easy thing for a blacksmith to manufacture as well which probably helps

    • @shawnbottom4769
      @shawnbottom4769 Před 27 dny +3

      They were used because there's no encumbrance on the sides or bottom. So no complicated fitting issues to overcome, just set it in place and done.

      Forging one of these is much easyer and can be done in a smaller smiths. Big claws require big forges and good metal quality. Small tools are easyer to maker

      Because if you make the slot slightly too big, the block can fall. Also, the key exerts an outward pressure on the block, which can split it if it contains cracks.

  • @peterrose5373
    @peterrose5373 Před 23 dny

    seems like it would be easier and faster to just stick the thing in a net, or just pick it up and carry it.
    In what contexts is this the quickest or easiest way to get the stone where you want it?

    • @Scarabswarm
      @Scarabswarm Před 22 dny +1

      In the context of having to place the block on a wall, and not having a net suddenly pinned beneath it. By carrying the block from the top, you can lower it into its exact place and not have to try and shift it while straddling a half-built wall 50 ft in the air.
      This is used on bigger blocks as well, the small stone was just for demonstration purposes. Nobody is carrying a 300lb block up a rickety wooden scaffold. Or having to one-hand it while trying to maneuver the net out from under it.

    I assume that was for setting a stone next to 1, or between 2 stones, with or without mortar. They didn't have a tong-like device similar to the ones used in the early 1900s when ice wagons delivered ice. (That's why "ice box" was used in reference to a modern refrigerator.) One can save time not chiseling a lewis hole. A rope & pulleys will lift a stone from the ground to an upper level of installation.
