Introduction: Modern Steel Fire Pit
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).

Supplies
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 - http://bit.ly/2J7geDW
Diablo Steel Demon 14” Metal Blade - http://bit.ly/2RM9gs7
Lincoln 140 MP Welder - http://bit.ly/31Z93Xb

Supplies:
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

I realized our mistake when I went to make this. His sides are 10x24, his ends cant be. Due to geometry which I'm poor at his ends would have to be roughly 7 inches tall. I ended up cutting mine at 10" and 35 degrees to get the 10" bottom but that means I need 12.25" sides. Good thing I'm new to this and not building it for some one other than myself. Lol

I agree, it appears he Mark's 45 degree angles on there but it would only give you a 4" bottom. He says his bottom is 10" in the video and you would need a 35 degree angle to achieve that. Hope this helps even though its 9 months later.

That's kind of the point of instructables. To help others know how to build it. Measurements are key to that.
Question 3 years 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.
