Craftsman-Style Pergola.

We cut the tenons on a tablesaw and cleaned up the tenon cheeks with a block plane, a chisel, a rasp, and a sanding block until they slipped into the mortises without binding. The technique I use to notch the beams also works for lap joints in the purlins and joists. We clamped the beams tight to the cross beams and set the 3x6 purlins in place over the beams. We used 8-in. screws to fasten the purlins to the beams and 5-in. screws for the joists. [Extracted from the article]
