Ttip from the Archives Splicing ridge boards

摘要

As a framing carpenter, I frequently come across a ridge span longer than the overall length of the material I'm using for the ridge. To extend the material to the correct length, I splice ridge boards with a V-shaped joint as shown in the drawing.rnMy crew and I call this technique "penciling the ridges," after the big pencil-shaped piece of wood that results when the cuts are made. To begin the cuts, overlap the ridge material with the crowns pointing in the same direction. The overlap should be at least equal to the rafter spacing (usually 16 in. around here). Now take a tape and mark the rafter layout lines as shown in the drawing. Draw cutlines from the center of the top ridge board to its end, and make these cuts with the sawblade set Va in. deeper than the cut. This will put saw tracks in the bottom piece, showing you where to finish the cuts.
