Made my first visit to a lumber supplier (other than a Borg) today. I went with a list of materials to make Norm's Adirondack Chair. I know all vendors will not be the same but I was caught off guard by the way the lumber was offered for sale (S3S in random lengths and widths). I brought home ten pieces, 92 bf.
Looking at the newly purchased stack in the basement I'm thinking I might have brought home too much Cypress for two chairs. If a laugh is appropriate please feel free.
Is their a rule of thumb or conversion formula for converting dimensional pieces to board feet figuring in for knots and random loss (ie 4" width bought for a 3" piece)?
