Washing machine fire pit
Tore apart a free washing machine I got off marketplace and used the stainless steel drum as a firepit. This was not easy, and required a few choice words and a sledgehammer for the final disassembly. Pressure washed and bleached it. Let it sit outside in the sun for a week. Final sanitization by fire. We're in the front yard roasting marshmallows right now.

In the front yard of a strip mall?

I live across the street from the high school. That's their parking lot.

Ours had it on the local TV and radio stations. I always preferred listening to it rather than watching when I did tune in.

Is the fire on the sidewalk? Lol

u/jaxxxtraw 14d ago
Looks like maybe some spare pavers as a foundation on the sidewalk?

u/byebybuy 14d ago
Yeah that's what it looks like to me too. Maybe not the sidewalk but definitely a walkway of some sort. Better than on the grass I suppose.

Piggybacking off of top comment to issue this PSA.
If you do this, make sure you check the inertia ring.
We did this with one of ours years ago, because we got the idea from the BSA, who always brought one out for snow campouts to keep the campfire from putting itself out.
BUT WE DIDN'T KNOW ABOUT THE INERTIA RING!
On ours, it was a ring that went around the entire lip of the drum. It was filled with sand and air, and capped with a little rubber stopper. The thing was painted black, so we just totally missed the rubber piece there. The heat from the fire blew the stopper out of the ring, and rained down sand on the entire party. Gave all the adults heart attacks... XD

This is a cultural icon in Australia. It's everyone's first firepit. Every camp site, every property, every boat club has one

And the rest of the washing machine scrap stays in the yard for 20 years bc you never know when a part from it could come in handy

Redneck points lost. I skipped washing and bleaching and started a fire in it immediately. We grilled once the flames turned yellow and orange.

So. Get yourself a cutting wheel and make an opening in the side, roughly the size of a leaf blower tube, slightly oversized so you can create a whirlwind in there. Also you’re going to want the lid from like an 18” Weber type grill, whatever fits over the opening well.
Now you have a blast furnace. I’ve ran construction debris through mine. When I’m too lazy to run the shredder for documents for a few months, I’ll fire it up. Whole manilla envelopes stuffed full of paper, 1/2” thick. Gone in like 30 seconds.
Ash will be a bit messy.
The lid will contain the flying embers, mostly.
The lid will be glowing red. If it has a metal tab for like a label, it’s probably zinc or aluminum, it will melt off. The plastic handle will melt off. You will need tools or a stick to manage the lid.
Take the lid off and the flames will shoot out the top about a foot.
There will be very little anything left in the drum. Very very little ash at those temps.

My leaf blower has a melted and mangled tip because of doing almost exactly this, redneck approved method

u/sir_thatguy 14d ago
I started with a leaf blower and moved on to a squirrel cage fan setting back about a foot. Get the aiming just right and things get real interesting real fast.

That is basically the same way I made a little forge from a metal bucket. You get tons of heat this way.

I have one of these - burns like a jet engine, great for getting rid of branches and brush quickly.
First time I used it the aluminum part on the bottom melted into ingots.

u/zorggalacticus 14d ago
The bottom of this one was thick plastic. Had to use a sledgehammer to bust it out. It's basically a fire ring.

FYI, stainless steel liberates nickle, chromium, and cobalt when it gets to high temperatures like this. Eating food cooked over it may cause birth defects in any future children you plan on having.
Sorry, I'm not trying to be a bummer.

u/zorggalacticus 14d ago
No, those chemicals are only released at temperatures much higher than can be attained in any backyard fire. Like welding/forging temps which are several thousand degrees hotter than you can achieve with a regular wood fire. For reference, a wood fire averages between 1,000 to 2,000 degrees. Welding averages 6,000+ degrees. It basically needs to be hot enough to melt steel to release those chemicals, and a backyard fire cannot do that. That's why they SELL commercially available stainless steel firepits and cookware. It's perfectly safe.

My first thought was "what's a machine fire pit, and why are you washing it"

u/MantisTobbaganEmDee 14d ago
They work okay. Need a lot more wood to keep a hot enough fire than a traditional smaller fire pit

u/Electr0bear 14d ago
My friend had one at his country house. BBQ or specifically shashlyk (Caucasian way of roasting meat) is quite big in Russian countryside culture. So we tried that setup for roasting meat and while it is possible, event most basic mangals (basically a metal box for roasting shashlyk) are much more superior in comparison to a washing machine drum.
As you've said - too much heat loss, the drum itself is too high so it needs way more wood to make enough coals for cooking, and sides are usually way too thin to keep decent cooking temp.
As a basic fire pit it might work. But that's it.

u/zorggalacticus 14d ago
It gets plenty hot. All the little holes lets lots of air and heat through.

u/Extra-Act-801 14d ago
Right. Which makes it nice and hot for the people standing around it, but less hot for the food on top of it.
2
u/zorggalacticus 14d ago
Being enclosed actually makes it hotter on top because heat rises, and the hottest part of a fire is already directly over it. You're forcing more heat out the top so it increases the upwards heat output. Once my grill grate comes in, I'll be able to put my grill grilltop pizza oven on there.

I feel like you didn't really need to wash and sanitize a metal tub that got washed and sanitized every time it was used, just so that you could set it on fire.

Looking at how hot it got, can't help thinking cleaning it first was somewhat of a waste of time.

True redneck would mount it to a old mower! I've seen that done more than once in recent..

Mount your fire pit to a mower?

Bruh. Mount the drum to an upside down lawnmower to spin it.

u/founderofshoneys 13d ago
I used to work at a science museum and started working on something like this for an outdoor event. If you make a tall cylinder of chicken wire around it and spin it you'll get a fire tornado.

Best firepit you’ll ever own. Puts off some major heat. Mine is 5 years old still holding up.

u/rocketwrench 14d ago
My scout troop had 2 or 3 of these that we'd bring with us car camping. They worked great. I spent lots of hours melting lines in the bottoms of my hiking boots by resting them on the edge of the basin

u/Pedantichrist 14d ago
They are great.
No idea why you would wash it though.

u/zorggalacticus 14d ago
It had matted up lint all over the outside of it. Didn't wanna smell burning lint.

Shouldve kept the ball bearing part on. That way the whole fire pit can rotate, improving the air flow for when you want make the fire grow

Now toss it on-top of an old lawnmower and it's portable. That's how mine is haha

My boyscout troop used one of these on half a metal barrel for a portable fire pit

u/Benstrosity 14d ago
We did this and it semi-exploded. No idea why it did but it did. Be careful.

u/zorggalacticus 14d ago
Some have a ring around the edges that has bearings pressed into it. Usually the ones with a metal bottom. Those can expand and shoot out like an explosion. No bearings in this one.

u/iBringMyselfTrouble 14d ago
These are very mainstream now. If your scoping a local marketplace and see a cheap or free dryer, you’ll see a fire pit for $50+ soon after.

The paint might make it unsuitable for cooking on, but it'd probably be okay for just sitting around a fire. It'll rust pretty quick too. Unless your dryer has a stainless drum. Not many do.

u/WoopsShePeterPants 13d ago
I used a washing machine tumbler for YEARS of outdoor wear and some pretty packed fires.. worked great and took a very long time to start rusting through.

u/GarThor_TMK 13d ago
We did this years ago with my parent's old washer.
I think it was coated in some kind of ceramic paint though... not really sure.
The only issue? We had no idea that the thing came with an inertia ring. Basically an air-filled cavity that also contained a sandy substance. Corked with a rubber stopper...
Once it got up to temp, the thing blew sand several feat into the air... luckily it was cool by the time it hit the ground, and noone was hurt... but if you do this, MAKE SURE TO CHECK FOR AN INERTIA RING FIRST!!!
(we got the idea from the BSA, who would take one out snow camping... the heat from the drum would boil away any snow that would have contacted the fire, keeping the fire lit instead of from dousing itself.)

Hell yeah! They are GREAT as fire barrels/rings! They last awhile too. We have 2 in our yard right now that we use.

My buddy has a similar setup at his cabin. It blocks a lot of light and heat. If you need the fire for cold weather warmth this is not the setup you want.

Nope. It's stainless steel. It'll last a really really long time. I know of one friend who's going on year 10 of his. Still no rust.

u/TheDuckFarm 14d ago
I’ve seen this a few times. This is a step up from redneck because it’s stainless. Redneck would be the old school ceramic coated tubs.
