It Can’t Be Denied-
The power of wood movement can’t be denied. It is so powerful, ancient peoples used this characteristic to quarry stones with which they built their cities.
Usually we think of wood expansion tangentially which makes a board wider. Sometimes wood will just twist.
We ran into an instance recently where a beam twisted so bad that it broke the metal bracket that is holding it in place.
Perhaps the beam would have just expanded along it’s width but it has the weight of a full sunroom structure on it. So possibly it diverted its’ energy and twisted to relieve the need for expansion. I have dealt with enough framing lumber and beams to know how bad they can twist, often dramatically enough to render them useless.
Here is an image showing the metal bracket and how it is supposed to look.
And here you can see that it is broken cleanly on the welds.
The brackets are only 4 years old and under shelter of the room that it supports. I suppose that some may question the welds but it is clear how much the beam has twisted and the wood has won out over the metal.
This isn’t a woodworking example in the same context of most LJ projects, but it does demonstrate the power of wood movement.
Peace, Love, and Woodworking
