How to Build a Custom Fire Pit Swing Chair Project

| August 15, 2014 | 0 Comments

There is something warm and inviting about sitting in front of a blazing fire on a crisp evening in the late summer or fall. However, imagine not only sitting around your fire pit, but sitting on swing along with several of your friends. This unique custom fire pit swing chair project takes your ordinary evening around the campfire and turns it into something very special.

Materials List

There is quite a list of materials needed to build a custom fire pit with swinging chairs. The number of swings will affect the amount of lumber and supplies needed. This particular fire pit swing set was designed for five 5 foot long commercially available swings.  All lumber used is pressure treated to ensure it lasts.

Materials List

6 – 6x6x8 used for the uprights

6 – 6x6x10 used for the crossbars

6 – 2x6x8 used for stabilizing crossbars on top

6 – 80 pound bags of fast setting concrete

10 – 3/8 x8 inch long eye bolts used to hang swings

24 – 3 inch deck screws used to install the 2×6 stabilizers

24 – 4 inch deck screws used to bolt the top pieces to together

24 – 4 inch deck screws used to bolt the top pieces to together before they are lagged in place

Beyond this you will need chain to hang the fire pit swing seats, paint if you want paint your finished fire pit swing set, and of course your fire pit and a number of paving stones to set it on. You can also use gravel to fill in the area around the fire pit and under the seats.

Building a Fire Pit Swing Set

As you set out to construct a fire pit with swing chairs, there are a number of steps to the process which must be followed carefully to ensure it will stand up to years of use.

1 Gaining a Little Distance

Before you start digging the holes for the uprights, you need to carefully consider the distance between where the fire pit swing seats will hang and the fire pit. You need to be close to enough to the fire to enjoy the warmth, yet far enough away so as not to become overheated. This distance will be predetermined by the distance between each upright. The most common distance is approximately four to six feet from the back of the swing to the fire pit. You can adjust this distance by increasing the distance between the uprights.

2 Setting the Uprights

When setting the uprights, they need to be far enough into the ground to create a stable post. In this particular instance, the ten foot long 6×6 posts are set three feet into the ground. They are then cemented in place, and braced to ensure they do not move while the cement is curing. Use a level on two sides to ensure they remain perfectly perpendicular.

3 Adding the Upper Crossbars

When the cement has fully cured, you need to add the upper crossbars. You can either calculate the angles or simply lay them in place and mark the angles you wish to cut. Each crossbar will need a lag bolt to hold each one in place. For a more aesthetically pleasing appearance, you should counter sink the bolts and seal them with a good quality silicone caulking.

4 Secure with Horizontal Cross Supports

Adding horizontal cross support bars may seem to be excessive, but will help to reduce the amount of strain on the uprights. These are run from the center of one cross bar to the center of its neighbor. They are secured using three inch deck screw to ensure nothing can move.

5 Finishing Up the Fire Pit Swing Project

After the entire project is complete, but before you add the seats, decide whether or not you are going to paint it. The pressure treated lumber will last for many years without being painted or stained, as a matter of fact you will need to wait for the wood to weather before painting so the paint will stick to pressure treated wood.  However, if you have not used pressure treated wood, this is a good time to paint it, as this will add a number of years to the life of fire pit swing set you have just finished.

Drill holes and install the eye bolts for the swings in the cross bars. You could use self-threading eye bolt here, but using eight inch bolts with nuts and washers will prove to be stronger as the will not pull loose from the wood over time.

For added safety and aesthetics, add a paving stone platform for your fire pit to rest on. Then add a layer of gravel around the platform and all the way out to the edges of your new fire pit swing seats set and your project will provide you with many years of warmth on chilly evenings.
