Fire Pit Swings

My wife saw something like this on Pinterest and desperately wanted one. The one she saw was hexagonal in shape. We didn't need as many swings so we went with just a plain square shape. We used 6x6s for the legs and posts across the top and used 4x4s for the angled support pieces. We built the swings using the plan from this website. All the materials can be picked up at the blue and orange stores. However when it came to the springs for the swings, the blue store was 1/3 of the price of HD. The legs are 12' long and buried 4' under the ground and cemented in for strength. Luckily I am retired military and was able to rent an auger for 1/2 the price of HD or the blue store. You could do it by hand but it saved us hours and lots of back pain. We found our dimensions for the size we wanted and spray painted dots on the ground where the posts were going to go. We dug the holes and stuffed the 6x6s in them. Using a post level we made sure they were plum. We braced them and added the quickrete and left them to setup over night. The next day we had to make sure all the tops were level with each other. This is where having some knowledge of physics paid off. I took clear tubing and screwed it above the height that I wanted on one post and then screwed the other end to another post. Fill it with water until the water level on the first post is where I wanted it (8 feet high) and it will automatically fill it level on the other end. There is a picture of this above. Water will always level itself out. I had to do this because my yard is at a slight down hill grade. We marked it and cut the tops off to make it level. After attaching the 6x6s on the top with 8" lag bolts it was time to paint. After painting was done we built 3 swings from Ana's plans. We shortened them by 6" to give room to walk between the legs and the swings. All in all it was a great project that only took two dedicated weekends. My wife still has to paint the swings though.

It sounds and looks like the top 6x6s are mitered and sit on top of the end of the vertical posts. I'd say at least one lag bolt each way to hold the mitered corner together and then at least one in each piece down into the vertical to hold it in place.
