Introduction: Brake Rotor Fire Pit
This was a bit of an experiment, trying to find a good use for old brake rotors.
The brake rotor is obviously the main material, but I also used this metal screen, some 1/2” steel rod, and some 1/4” rod.
Step 1: Lining the Rotor With Steel Mesh
I believe this screen is stainless, but it might just have some sort of galvanized coating. Either way my tin snips make quick work of it. I cut out a circle to go in the bottom of the rotor and keep ashes and whatnot from falling through the holes. I didn’t want to cover the holes though, because having plenty of airflow underneath the fire is very helpful.
Step 2: Cutting the Legs
Next I made the legs. I wanted them to be about 6” long, so I cut three 12” lengths of the 1/2” rod.
Step 3: Bending the Legs
Even though I cut a notch in the center and used heat, they still snapped when I tried to bend them. That’s okay, that’s what welders are for!
I used this welding magnet to hold the two halves at a 45° angle and weld them.
Step 4: Attaching the Legs
Next I welded the legs to the bottom of the rotor. I eyeballed the spacing, but they were about equal-distant. The triangle shape of the legs meant that they all flared out at the same angle.
I was surprised how well the rotor welded. I was expecting it to put up more of a fight.
Finally I used a flap disc on my angle grinder to round over the points of the legs.
Step 5: Cage Vertical Pieces
Next was the cage on top to hold the majority of the fire. I originally wanted to use more of the steel mesh, but it just melted away when I tried to tack weld it.
I cut six pieces of the 1/2” rod at 3.5” each. This just seemed like a good height. I arranged the six rods in a hexagon shape. Placing one above the center of each leg and one directly in between each pair.
I used the same welding magnet to hold them as vertical as possible.
Step 6: Cage Horizontal Pieces
Last were the horizontal pieces. There were 18 in total and I cut them from 1/4” rod. I originally cut them to 5.5” long, but ended up having to go back and custom trim each one to fit. I cut this spacer block to hold them at the same height while I welded them in. Unfortunately my block was a bit too tall and I didn’t get all three rows equally spaced. At least with the top two being closer it almost looks intentional!
Step 7: Complete
The last thing was to put the screen circle back in and give it a test! It fit nice and snug with just a pressure fit.
