Raising a timber framed gazebo on a floating dock in Alabama required math skills and equilibrium!
The Cypress octagonal gazebo required some different layout. We cut the five-sided posts on our sawmill, along with the six-sided "boss pin."
Boss pin is the name of the timber that drops down from the peak of the gazebo. The rafters and knee braces are all connected to this timber with mortise and tenon joinery and it holds the whole roof together. It's in charge, hence the name!
As wood ages it shrinks. If the boss pin had shrinkage the entire roof structure would be affected and could lower. To ensure this doesn't happen we sometimes hollow out the boss pin where the rafters connect to it and insert kiln dried oak. Kiln drying removes excess moisture and significantly decreases shrinkage.
