Fortunately, I have found a couple handy tools for helping me build things like this. One is the internet. I swear you can find out how to build anything on it. Need a time machine? No problem. The second is Google Sketchup. If you like to build stuff this is an awesome tool. You can sketch what you're building with Sketchup and then you have all of your measurements and diagrams at your finger tips. It's free and it's invaluable. Here is my Sketchup of the pergola.
Doug was kind enough to dig the holes, drill the holes for the through bolts, and help Kris carry the 6x6s. I know it was hard work and it doesn't help that Doug's back isn't much better than mine and Willard Scott is going to be showing Kris on a Smucker's jar soon, but I am extremely grateful for their help as I would likely be in surgery again had they not been there.
I notched a decorative end to each 2x6 with my Skill saw and then finished the cut with my jig saw that Kris got me for my birthday. I had to get a new jig saw because I have a lot of my grandfather's tools and they no longer make blades for his old jig saw. It's too bad, 'cause that thing was ol' school. It was all stainless steel and shiny. The new one is plastic but it can cut a 2x6 like toast through my fiances skin (if that doesn't make sense to you, you need to ask me about the time my fiance cut herself on a piece of toast. I'm pretty sure her skin is made of meringue).
Once the 6x6s were in place the rest was pretty easy. We bolted 2x6s to each side of the 6x6s for girders and then laid the remaining 2x6s across the girders. I toe-screwed them in place with 3" deck screws at the bottom. Then I ran seven 2x2s across the top and drove a 3" wood screw through and into each 2x6. It's solid as a rock. Three days after completion it withstood 60mph gusts of wind. Kris plans to plant some wisteria around the base of the 6x6s to help create some additional shade.
