Pergola bay — materials
A rough list to take to a sawmill. The frame is cut green — full-sawn timbers straight from the log — and pinned with dry oak pegs: as the timbers dry they shrink onto the pegs, and the drawbored joints pull tighter. The mill cuts every stick to its section and length; the framer cuts the joints.
Each length is the piece’s cut length plus 10 in for tenons and trimming, rounded up to the foot. A piece longer than 24 ft is ordered in two or more lengths joined by a scarf (A2-16). Board feet are full-sawn: width × depth × feet ÷ 12. Sizes follow the model, which is proportioned from measured drawings, not engineered — a frame that will carry a load is sized by an engineer first.
