In this Instructable I'll show you how I made this modern steel fire pit. It was my first full metal project (most of my others include woodworking).

1/8" mild steel plate

1/8" mild steel square tube

1/8" mild steel bar

Step 1: Gather Materials and Supplies

The materials for the fire pit are pretty basic. Just some 1/8" plate steel and square tube. I also used some round bar for a grate.

Tools/Consumables Used:

Diablo Steel Demon 7-¼” Metal Blade -

Diablo Steel Demon 14” Metal Blade -

Lincoln 140 MP Welder -

Slow Speed Chop Saw -

Large Right Angle Magnets -

Small Right Angle Magnets -

Edge guide -

Gorilla Grip Gloves -


1/8" plate steel

1/8" square tube

1/8" round bar

Step 2: Cut Metal Plate to Size

I started by cutting the plate steel down to size with a metal blade in my circ saw. The design is very basic with a 24x24" top opening.

I cut two sides to 10x24 and left them rectangular.

Then I cut the other two sides with 45 degree angles on them. This would give me the sloping sides

Lastly I cut a piece to fill in the bottom.

Step 3: Cut Square Tube for Legs

I cut the square tube to size for an A-frame style leg. The angle on the legs splayed out 15 degrees.

I made the cuts on my slow speed chop saw and matched all the angles for clean corners with no open ends except the bottom.

Step 4: Weld the Fire Bowl & Grate

I used some setup magnets to hold the sides together and welded them with 0.25 MIG wire.

I worked my way around the bowl until I had all the sides attached and then laid in and attached the bottom.

To hold the wood off the bottom I welded up a grate from 1/8" bar. This sits on some small triangular standoffs I welded to the bottom of the fire bowl

Step 5: Weld the Base and Attach to Fire Bowl

Next up I welded the base together using the magnets to hold everything in place.

I added two stretchers between the leg assemblies for some extra support and strength.

Then I welded the base to the fire bowl using a set of wood blocks to hold it where I wanted it.

Step 6: Finish Up

I added some drainage holes in the fire pit to get rid of any standing water and called it a wrap!

    I love this design but I’m missing something really basic - Can someone please help? Two sides are 10 inch X 24 inch and each end is 10inch X 24inch with 45 degree angles at each end. When I mark these angles it leaves a base that is just 4 inches in width! This does not look right as the video images show a base that is far wider than that. Can you please send the actual dimensions of each piece? Sorry if I’m missing something really basic but I can’t make it work when I sketch it out. Thanks in anticipation! Cheers


    Question 8 months ago

    Are all 4 sides 10 x 24?
    What is the size of the bottom plate?
    A quick drawing with sizes would be very helpful.
