When the old gate fell off its hinges and proved unsalvageable, it was time for a new project.
After a trip to the store for pickets, a 2X4, and some hardware (don't buy the prepackaged gate hardware - it's more decorative than functional), it was time to pull out the power tools and get to work.
I love these guys - they're hand-me-downs from my inlaws, older than I am, and tough as nails.
I measured and cut and put the gate together flat on the driveway, laying out the cut 2X4 in a Z and screwing the pickets to it. After putting the hinges on the gate, I propped it in place with some 2X4 scrap, and 8 lag bolts later, the gate was hung. Somewhat unorthodox, but it meant I got it done by myself within a couple of hours. The little helper helped by napping during most of that time.
And because this is a girl's home improvement project, instead of being any old gate, it became a butterfly gate, with the help of google image search and the jigsaw.
