Tonight, I ripped the lumber for the yard and boom. These will hold the top and bottom of the sail to the mast. Each will be formed by laminating (glueing) two 3/4″ x 1-1/2″ pieces together. Since these will each be 11 feet long, I ripped the required pieces from two 1 x 4 x 12’s using a table saw. This one is on loan (Thanks, Fred H!) – my saw would do it, but this heavy duty model is better for the task.
The problem with these rips (cutting a board with the grain along its length) is that the length of the board makes accurate alignment difficult. To best position the board, I clamped featherboards to the table saw to force the wood laterally into the saw’s fence and downward onto the table surface. The finger-like projections are set on an angle that allows the piece to move forward into the blade, but limit backward motion. They work well – here’s a video description of a set-up the differs slightly from the photos above –
