Have a great weekend everybody! I've been working on new additions to my Amazon store: www.amazon.com/shop/farmcraft101. And don't forget to check out Kevin's channel if you are interested: kzfaq.info.

John, as a long time sailor I’ve had a lot of experience with brasso and polishing. Your beautiful fire extinguisher will quickly collect fingerprints like ants to sugar. To make that shine last I’d suggest spraying it with lacquer.

One other thing... If you were ever planning to really use it. The glass acid bottle is supposed to have a lead stopper in it that falls out when turned upside down. It's just enough to seal in the acid against being splashed out into the soda water accidently.

For the letters you can use a large flat piece of wood or metal, stick some fine sandpaper to it and use that to take off only the high spots of paint (that is covering the letters).

I think the inner container was slide up from the bottom and then the cap at the bottom was pushed in and then they rolled that seem at the bottom area to crimp it all together 😀 the reason it's so obvious is that the hose is threaded into the inner vesal, that means the inner vessel was built and drilled, tapped before installing into the copper outer skin.

Great job on the restoration. Came out great. Just a little warning. Whenever you attempt to charge and use one of these as either a demonstration or just playing around, keep exposed skin away from the nozzle when you invert it. The first few ounces of liquid that come out are more often than not, mostly straight (or nearly straight) acid.

Many years ago my grandfather had 8 of these extinguishers hanging in his used machinery warehouse where I worked a high school job. The place was large and customers could browse without too much oversite. I caught site of a customer just closing his trunk on two of these copper antiques. I said hi and asked what he put in his trunk. He hemmed and hawed a bit just as all heck broke loose and fluid started streaming from the back of his car. He had no idea how these worked. Sheepishly opening the trunk he viewed the mess and turned over the pilfered extinguishers.

I do actually remember these, also another type where you had to invert and strike a plunger on the ground this drove a pin through a glass vial of acid. As a kid I found some of these vials and carried them home in my pockets! No ill effects!!

That fire bottle really looks good, John

Fantastic job! Yesterday my wife came to me with a solid copper mixing bowl, after trying the paste solution and asked it I could improve on it. I put a wire cup brush on my cordless side grinder and followed up with Scotch Brite, and got it back to looking like new.

I'm a babyboomer, those were pretty common when I was growing up. I had no idea how they worked until your demo. Nice restoration.

A fire extinguisher with built-in instructions on how to recharge it is pretty refreshing to see.

When painting raised letters like that, apply a thin coat of Vaseline to whatever you don't want painted. Then paint. When paint dries, just wipe with a cloth. The Vaseline will come right off and that part will not have paint on it.

man your restorations always come out amazing, at least you take your time and do it the right way unlike 99% of restoration channels. keep up the amazing work and hope to see more cool project's like this in the future!!

I vicariously restored my fire extinguisher by watching this video 😄. Seeing all the work "we" put in, I dont have the urge to restore "another" ...WE did a great job! 👍

Just happened to visit your site since joining awhile back and found you working with the fire extinguisher. I happen to have one that came from my two-room grade school in Grape Creek, Illinois. My father was on the three-man school board at that time, in the late 1940s, and I was helping him to get the school ready for the fall session. Those old extinguishers were being replace with newer models and dad gave me one but I had to discharge it. So I did, outside. I still have the unit and it is far better shape than the one you were given. so I've not done any work on it. One of my heirs will inherit it soon, I'm 84.

another underrated video

I grew up in the era of that type of fire extinguisher and I seem to remember that the acid container had a weighted cap that just set on top. It would keep the acid container sealed and would fall free when the extinguisher was turned over for use.

Stay strong!

It’s amazing how resilient you are! Wow

you can use an air hose from an auto shop to replace the old hose on the extinguisher. Thats how i did mine.

Nice restoration! I got ahold of one of those in the first radio station I worked for (they were just in accounting & sales, CO2 in engineering spaces). Insuror required a change to ABC extinguishers, and the folks that sold them to us were nice enough to offer to haul off the old SA extinguishers. I snagged one and turned it into a nice lamp.

When painting with a rattle can, Light fog coat first, let tack, then work up to final heavy shine coat.

it amazes so many how efficient such simple technology still is, but when you look back at how long these were in use it really makes sense. There is something to be said for the "KISS" method. Keeping it simple but elegant will never go out of style. ♥

This turned out beautiful

Jon, Having watched pretty much all of your videos, I'll be honest and tell you that I did not think I'd like this one. I thought it would be lame. I was wrong. This Antique Fire Extinguisher video may very well be the best one that you've done. Expert craftsmanship, very fine workmanship, excellent explanation of the working parts, etc. Plus, the fact that you put your better half in the video and gave her the credit that she obviously deserves for keeping your stunningly gorgeous farm running smoothly whilst your goofing off with your "work" made me smile. You're a good man. You remind me of my father. Keep up the good work! Warm regards, Al p.s. this is the first comment I've made on your videos. You've made an impression on me with this one.

Im so glad you left the dog trying to eat the cow pie - your videos have some good laughs in them

That thing is BEAUTIFUL! 😍 Keep making videos like this, please!

Johnson, squirting extinguisher, getting the paint off. But the jealous dog segment was even more hilarious. Scratch me! Ooh poop! lol

Anyone aside from me enjoy watching the shop beetle scurry around at 23:18?

Such a snazzy looking fire extinguisher, plus the chemical reaction powering it is so elegant!

My grandpa used to paint letters that he welded on his “creations”. He would apply grease to the top and then paint. Afterward he would wipe off the paint from the top. Not very precise but other applications of a similar idea might work. Great video. You are one of my top creators. I rank you up there with Astrophysics and machinist videos because of your thought process and your effort to do things right. Always interesting and rewarding to watch!!! Keep it up!!! Go Ukraine.

Those seals crack me up so much I have to stop the video to finish laughing before I can continue watching. Surprisingly funny faces on those seals. 😂 Coffee and tears flying everywhere here at my place.🤣

As always GREAT!

Fantastic video! I really enjoyed it! Once again reaffirming that FarmCraft101 is my favourite channel on KZfaq. I love the variety of subject matter that we get to experience here. Thanks for making this video! 😎👍 It's so cool how simple and effective this old style of fire extinguisher is.

When I worked rebuilding industrial electric motors I just brushed some muratic acid on old green copper in order to cleanly braze on fresh lead wire. Worked quick and made it shine like new with a quick wipe from an abrasive pad afterwards.

As a teenager I bought one of these extinguishers empty. Reading the instructions on the exterior I bought a container of baking soda and a flask of sulfuric acid. The flask is placed in a holding cage inside the top of the unit. When upsetting the extinguisher after it had sat many years in our hallway the whole bottle of liquid was expelled. I have since watched many hundred thousand dollar farming combines burn to the ground. Every one of these combines needs this extinguisher installed in a hook on the wall with a rip strap holding it in place. When the combine ingests a stone it causes sparks igniting the straw in the eccentrics and when the operator smells smoke he should immediately lift the side door of the combine, and with THIS EXTINGUISHER douse the fire saving his harvest year.

The salt is the abrasive and the vinegar is the cleaner. The flour congeals the solution and makes it less runny and more sticky. You could also coat it with ketchup and it would do the same thing just would have to leave it overnight. :)

Very beautiful restoration, thank you for sharing your amazing story. God bless you and your family.

Fantastic results. Lovely piece of functional art. Really enjoy all of your videos.

I came here to view the content once I knew it was FarmCraft101. I would have eventually realized it was your channel. However, without your prompting I didn’t realize by the thumbnail alone. I quite enjoy all of your diverse content and this was no exception. Thank you for putting out such interesting stuff. I have learned an awful lot about a variety of things from you.

had some of these in a lodging home all polished up.,fire department said they had to go not legal anymore.converted them into floor lamps , should have seen the look on fire marshalls face on next inspection, priceless !!! gord

The Part with the red color is great!Good job👍Greetings from Germany

18:48 The classic "dog sniffs at poop and you push it away before it has the idea to roll in it" lol

Amazing video as always! Its crazy how ingenious the design is. Simple and effective

Awesome job

John, I have a similar one sitting under the table saw. It's a "PYRENE" Soda Acid, all brass I've been saving for decades to restore. It even has four paper Pyrene tags attached to the hanger, one reads (in pencil) 'Last charged 6-11-1959'. The other old paper tags could be from the 1940's with original manufactured numbers, model, etc., who knows? Thanks for the reminder, I just pulled it out from under the saw dust...just made a walnut roll-top desk and didn't have time to clean yet.

A like for each time resources are reused, like the battery acid.

Yep, stuff and things.

Nice Job!

Nice and careful restoration. Great job!

My grandmother had at least 100 of these in the attic. Friend worked as a janitor for school district and when they switched to modern fire extinguishers they were being thrown out as trash. I've got one now residing on my fire place mantle for decor.

Probably the most known example of this style fire extinguisher was used by Doc Brown in Back to the Future to put out his wastebin fire of oily rags after the “crude model” demonstration. I happen to have the exact same one you just restored.

Awesome Video!

Right on!!!!!!!!!!

Very nice!!! I’m always impressed with your work!

Interesting to see how it works, Great job in restoring it. For the painting, while it is wet you can use a flat block of wood with a thin cloth like a tee shirt stretched tightly over it and damped with a solvent. It will wipe just the letters clean. Easier and faster than a Dremel after its dried.

Good show

Gorgeously satisfying! Or to put it another way; good job! 😊

When we were kids, we used to use salt and lemons to clean and polish the copper bottoms of moms pots and pans. It could have worked pretty well on this too.

Nice! Turned out awesome. That’s interesting it recommends recharging at least once a year, really cool!

One day I will have watched all of your videos and enjoyed most. Some I have chosen not to watch but I'm learning. I get so tempted to bring you stuff to play with but Louisiana is a ways away and my budget does not allow. I don't send stuff to people. I must hand it to them. A quirk of mine. lol As usual, GREAT VIDEO. THANKS.

Dude, you’re determination is amazing and admirable. Even awesome I’d say!

Awesome job!!! ❤️❤️❤️👍🏻👍🏻👍🏻

Growing up, I remember my parents having one of those in the house. I think it was decoration. I wish they still had it as I love that old kind of extinguisher.

Excellent job. I tidied up one which someone had partly sanded with a coarse grit previously. It took me so many hours to get it half as good as yours. Anyway with a slit in the top it makes a great money box.

I remember seeing a few of these…probably more as decorative…I’m in my mid 50s and I remember when I was 3 or 4 some really old theaters and department stores in Philadelphia had these things around…they also had the typical red fire extinguishers too…but it just sits with me…I think our church had one too…it dates to the 1700s and they had one of these in the basement…where the nursery was…back in the mid 70s…weird I know…

Great video! I had absolutely no idea this is how fire extinguishers used to work. I was surprised how well it actually worked and how long it ran for.

I'd have agreed that the fire was not technically completely extinguished. I wouldnot have expected it to completely burn down after this though. Intresting!

Here for the seals.

just a tip i have spray painted overtop of old letters on bucket trucks drippin with grease and hydraulic fluid and ETHER works really well at degreasing stuff ...spray it whipe it and the air vaporizes kinda like alcohol does spray it again whipe it ...PAINT ALL DAY LONG no beads no runs .. ;)

I think I missed this upload because of the thumbnail. Didn’t realize it was one of yours in my feed. Comparing to the Antique Ford Wheel restoration from a couple months ago I think that thumbnail is a winner because 1) it’s immediately clear what you’re restoring, 2) it teases the end result, and 3) your logo ‘pops’ really clearly over the red paint! Just my 2 cents - hope it’s helpful. I found your channel during your cannon casting saga and have been really enjoying your content since! Keep ‘em comin and I’ll keep watching!

I have one that's been in my family ever since I can remember and much longer I'm sure. I'm gonna restore it too. It's in great shape already still has the bottle and lead stopper in it

I saw your ask, so I watched and enjoyed the video-as I have many videos showing how old things work. Considering why people watch your videos to make title and image may help with consistent views? I like learning how old things work-and you do a great job at figuring it out and sharing that adventure. A title like “spraying this 1940’s extinguisher” and image of it spraying-or before/after mirror might draw me in? I like to know how/why old things work-and see inside mechanical things gadgets as simple things are best. The title inferred that exactly, but I didn’t think I’d be interested until I realized it was your video and started watching! I hope this feedback was helpful-but I can’t see how it can be lol! -I enjoy your work-thank you.

Looks like Kevin the "Picker"picked you a duff extinguisher! Thanks Kevin!

Good!

Good stuff not sure how this video only has 10,000 views…. People take for granted fundamental engineering like production tolerances pressure vessels and seals. However back when these were built none of those standards existed. It was extremely difficult to create a pressure vessel which would hold pressure for long periods of time. We all stand on the shoulders of giants.

Amazing! Supercool to see /Henrik

That 1:1:1 (by volume) salt, vinegar and flour mix seemed to work well for getting the oxides off, I'll need to remember that!

Great video! I learned so much, thanks!

That green stuff is called Verdigris

For future copper cleaning, make what's called 551. It's 500ml water, 50ml hydrogen peroxide and one ounce of citric acid

Have notifications on but nothing was in my tab, didn't know you uploaded

Loved the video! Keep it up!

LoL ... love your videos especially your sense of humour

I saw you take a sip at 12:06!

Pressurized water extinguishers are still used today, plain water (may have a few ounces of foam concentrate added), and pressurized with an air chuck. I am familiar with New York Fire, the ladder truck crews will carry one into a building when they go to the fire room. Not having to carry and maneuver the hose, they get there rather quickly. 2 1/2 gallons of water can darken down a fire rather effectively, and since they have a "trigger", they can shoot in bursts.

Talk about pissing a fire out!! As always, great video.

Hi from Commonwealth picker! He sent us over to see this. I love old fire extinguishers. Subscribed too.

Damn amazing

I have homemade versions of these with vinegar instead of sulfuric acid. They key here is that the water should have dishwashing detergent and the foamy output contains bubbles of CO2 which acts as a surfactant and the CO2 displaces atmospheric air that contains 20% oxygen

reason they were outlawed was bcuae the hose could get clogged (mud daubers, chewing gum, broken pencil. I m a retired firefighter and a firefighter in Florida in early 60 s was demonstrating one and forgot to check hose for blockage, it exploded killing him. They were soon oulawed

Cool

Nice quality video. One issue i have just as a bottle guy. Get that milk bottle outta there. That thing was from the 20's or 30's. Im pretty sure there are nicer options for replacement bottles for the long run. Look through those loft bottles. I have a few and those fit the bill for some nicer ones.

I love it. BRAVO. I am fascinated with creative and innovative builders, crafters, repairers, etc. I am referring you to two other KZfaq channels I have, or do, follow. One is a restorer of old tools (great sense of humor): Hand Tool Rescue. The other is a creative (kinda kooky) inventory/builder of pretty useless things: Colin Furze. He has a very cool workshop you would probably enjoy seeing. Plus, he built a fantastical tunnel under his yard!

Simplicity of design and if you had access to H2SO4 from the local hardware store, you could maintain it yourself quite easily.

Can't see anything wrong with this video. I really enjoued it! Just like all your videoes. :)

So be it. Cough no more!

That looked gorgeous when you were done. I was skeptical the entire time for some reason lol.

This is awesome. My grandfather had one on his porch. Maybe it was functional, I'm not sure, they had a wood stove there for a long time.
