Had an 20+ year old pergola falling apart on my back porch. Designed and built this 16x12' guy over the course of 2 days.
I built the whole thing using and impact driver, and a miter saw for cuts. I used joist hangers for the cross pieces as well.
It's designed to handle up to 1 ft of snow without sagging, which would be a record for this part of NM. So far seems to be holding up.
Really happy with how it turned out.
Thanks! One of the keys for me is there are no screws with pure sheer loads, unless it uses a joist hanger.
