I’d like to put one on the patio. Any suggestions on what brand, where to purchase, what to avoid, etc?
A proper fire pit isn't an accessory type that you put "on" the patio, is that what you're asking about? Like these> https://www.wayfair.com/outdoor/sb0/fire-pits-c215964.html?rtype=9&redir=firepit
Are you in a city? Do you need a burning permit? I think we do, and the fire needs to be encompassed by a metal grating of some sort.
Go out to your rock wall and pick out a tractor bucket load of reasonably flat stones...the bigger the better. Go back to a flat spot in the field behind your house and lay out the stones in a circular pattern, stack them 2 feet high. Go back in the woods and collect a bunch of dead sticks and limbs, 3 or four arm fulls should do. Pile them in the ring, dump a quart of kerosene on the mess and lite on fire. Don't forget the marshmellows.
I've got a 40' ring of sand with a big hole dug in the middle. Fire's get a little large sometimes.... Just spent a couple hours raking it and cleaning it tonight for a party we're having tomorrow.
Got a brick ring, 15ft in diameter. Used to make 20 ft high fires with pallets from work. Wife wanted something more civilized... 18 bags of concrete later i had a 5’x5’ square in the center of that ring, that i lined with fire bricks and fire-mortar. Holding up well and cost less than $200. (Including the 3yds of gravel around it) Of course, built in August (hot) after i messed up my lower back in June (squatting).
We were throwing away the extra air tanks from the shop since we couldn't give them away. Waste not want not...
That's how I start them at camp. Old rotten gas mixed with some used oil to lessen the explosion. Never sure what the mix is so sometimes the boom is kinda big. I'll have to take a few pics this weekend of the fire pit up there, big semi circle of used cement blocks 6 or 7 high, I keep adding to it as the ash gets deeper.
