In this article, I am going to show you how I made this eight sided fire pit ring that I call the FrankenPit.

The bricks are optional. I use them to keep the ring off the ground and to give me a solid base.

The heart of this fire pit build is the rectangle component shown here.

Mine measures 10” tall by 17” long. Just about any size rectangle will work as the segments in your fire pit. While the thickness of each segment can very, the height and length must the same.

The 10” will be the height of your pit, most likely it will be determined by the kind of stock you can round up for the project.

Originally mine were going to be 12” tall, but I did not have enough scrap on hand.

The length will determine the overall size of your fire pit. A size of 17” will give you a pit at about 40” from side to side.

You can create the segments by any means you have at your disposal.

• Cutoff Wheel

• BandSaw

• Hand Snips

• Plasma Torch

I chose to use my CNC Construction Set plasma cutter.

Note that the scrap that I am using is painted, so I had to clean an edge and add a jumper to make sure the torch could transfer the arc.

I do recommend using some sort of torch height control. For this project I am using the CAP04 Capacitance Torch Height Control.

Even though the steel that I was using is warped, I had no problem cutting the pieces I needed for the eight segments.

Note that I did fall short on scrap. On one of the pieces I had to joint two smaller piece together to make one 10” x 18” segment. Hence the name FrankenPit.

One inch on one end of each segment needs to be bent at a 45 degree angle.

Here is my HF three-in-One. It struggled to bend this 18 gauge but got the job done.

For the thicker pieces I had to move over to my 20 Ton finger press. The thicker the material you use for the harder it is going to be to bend.

The finished segment.

All eight segments ready for assembly.

My young helper will assemble the eight sections. Here you see here sorting the hardware.

• 24, 1/4-20 x 3/4” Hex bolts

• 48 1/4” Plain washers

• 24, 1/4” Lock washers

• 24, 1/4-20 Hex nuts

A bolt with a washer is slipped through the flat end on one section and then through the bend end of another.

Another plain washer, lock washer, and hex nut are added to the inside.

All the bolts are added and only finger tightened. Once assembled, she goes back and tightens all the bolts with a 7/16” socket.

Two segments.

Note that one of these pieces was the one I had patch together earlier.

Three segments.

Four segments.

Five segments.

Six segments.

Seven segments.

All eight segments.

The fire pit ring is placed on my bricks, but could have just as easily been placed directly on the ground.

The pit is loaded with dry wood.

After about an hour of heavy burning, the paint has pretty much burned off both the inside and the outside.
