I have built a 7' x 13' pergola over my deck and have a slight wobble, so I intend to install some knee braces. Each post has two pairs of perpendicular beams stretching to the adjacent posts. For the brace-beam connection, a simple through bolt will be easy to do. But what's the best way to secure the brace-post connection ?
I was hoping to use a through bolt here too, but can't figure out how to create a surface to hold a washer to the angled face of the brace. Any suggestions?
