A lewis is one of a category of lifting devices used by stonemasons to lift large stones into place with a crane, chain block, or winch.It is inserted into a specially prepared hole, or seating, in the top of a stone, directly above its centre of mass.It works by applying principles of the lever and utilises the weight of the stone to act on the long lever-arms which in turn results in a very high reaction force and friction where the short lever-arms make contact with the stone inside the hole and thereby prevents slipping.

Lewis pins = back saver 💪#bricklayerssocialclub
Using Lewis pins on some Portland stone,
These Lewis pins were suitable to lift 500kg and the stone weight was 220kg so was more than sufficient.
When using Lewis pins ensure you drill a deep enough hole to accommodate the pin clean the hole out and be careful not to jolt or remove any of the pressure on the pins.
As always make sure you and anyone else working around you is not underneath.
