building a pergola - fixing post and beam. one of the most important decisions apart from style, lies with how you want your pergola construction to be made - this will have an everlasting effect on the final look of the structure. the big question is to notch or not to notch.
my pergola is of a different design and the 'rafters' are notched so that they are at the same level as the main lengths. the rafters are every 3 feet and fixed with two nails at angles - toenail? the upright posts 4x4 are every six feet and the lengths and rafters are bolted in place with coach bolts.

pretty hard to envision what you are doing, or what kind and size of notch you are making, but if you are talking about a ridge beam, and the rafters will set on top of the beam, you generally cut a birds mouth in the rafter just like you do when it is sitting on a top plate.
