I'm a corrosion engineering major. One thing you missed is the fact that cat urine contains a TON of chloride ions which are pretty rough on 99% of metals.

"I have stopped trying to find logic in people's actions" that's a great statement 😄

"I stopped trying to find logic behind people's actions" And that, right there, is the key to inner peace.

I had a summer job as a porter once, and had to dispose of a garbage bag of litter a weird cat lady put out. It was leaky and the litter was ancient, the stuff dripping out of it was the color of old motor oil and so noxious my eyes were tearing up. (as I dry heaved while trying to get it into the collection bin without getting any on me) I feel deeply sorry for whoever had to dig those guns out...

"I need to delicately active the cylinder release" Cut to a clip smashing it with a hammer and punch. Love these videos! I'm intimately familiar with the 92 so it's fascinating to watch you work on it and learn more about materials science and firearm restoration.

2:18 - "The smell would upset NileRed himself." It couldn't have smelt _that_ bad, surely? That dude literally smelled the stinkiest compound known to man, and the stinkiest chemical mixture ever produced, and was like "It's not as bad as I would've expected."

"The stench would upset NileRed himself" I've seen enough NileRed videos to know he'd react by saying "It's honestly not that bad..." while his cameraman is having a stroke.

A first for me! I restore old rusty firearms for a seller and have seen some crazy stuff but NEVER cat shlt! Craziest one for me to come in was after being hidden in a pack of frozen beef liver found in grandpa’s old freezer! A pair of old Walther P38s. Same guy also brought in an old plastic milk crate full of P38s found in the barn. About half of them were restorable but only a small handful ended up with all matching numbers. We built quite a few combining the best parts.

Honestly, this sounds like a textbook case of hoarding, which is almost always linked to profound mental illness. I hope that they're able to get into a better situation and get the help they need.

I have a S&W 2206 that was in a storm sewer for about 10 years. It was packed with dirt, sand, and mud. I had to replace the blued rear sight and the nickel plated controls but it turned out great. Especially compared to your 38 revolver.

I'm a plumber by trade, I had a customer who kept a cat box in a extra shower stall she had. The call was shower dripping. When I pulled back the curtain the ammount of damage from the ammonia in the air was extreme to say the least. I began to take the handle off, first step in seeing what type of valve it was since all markings had disappeared. Well the first step should have been to give an estimate for a new shower valve, when I turned the handle to look at the set screw it blew off in my hand with the front of the valve attached to it. Luckily it was a shower stall and I just closed the curtain and shut off the water but man. Im surprised there's anything left of that pistol.

Unexpected NileRed mention at 2:18 haha

Nice rescuing work ! Hope the cats too are at very good care.

12:38 “I need to delicately activate the cylinder release mechanism” *proceeds to bash it maliciously with hammer*

"First of all, I need to delicately activate the cylinder release mechanism." *BANG*BANG*BANG*BANG*BANG lol

I love how you give detailed explanations of the mechanisms, corrosion and history of the guns. It's not just eye candy, it's also pretty educational

"I needed to delicately activate the cylinder release" - Dumbledore said calmly.

this video was absolutely nuts. ive never seen anything this bad. it's absurd and unlike anything else on your channel. thanks for uploading!

Amazing video, thanks. You must have the record for the most horribly corroded firearms. Love the humor you worked into the dialog!

So, don’t store my guns in litter boxes?

Holy shit dude, you blew my mind with that little trick for those stuck handle screws. I never thought about putting it in a vise with a bit and turning it with pressure that way, you are an absolute genius

The most fragrant video so far.

Excellent work as always. You’ve made restorations a work of art. Outstanding

Bellissimo Backyard Ballistics, superb like allways !!!! GRANDE SALUTTI !!!

Much awaited, much appreciated excellent insights as always from you.

All you had to say was "Cats," "Rescue," and "Buried in cat excrement," and I knew it was in possession of a hoarder. Say no more. I've seen what hoarders can do first hand.

Amazing video as always. Thanks for taking the time to film it.

Awesome video my friend that's still impressive that you were able to bring two of them back to fully functioning order I always enjoy your videos keep them up

Definitely enjoy your videos for all the informative things you show in them, can't wait for any new videos from you dawg

Awesome I've been waiting for another video you do incredible work!

this guy feel like more of a chemist than a gunsmith tbh

4:24 “I don’t know where rust ends and poop begins to be honest” I have a suggestion. Yes

Thank you for restoring these items, it is a peace of mind knowing these guns are kept in better condition than what they were

OH BOY. Another Backyard Ballistics video. Happy day.

Always great stuff.. most impressive.. it has been a while since content... more please.. thank you for all you do

love all your videos anyways, but this one was special for me as i collect beretta 92's. thanks for always putting so much information in your vids!

Dude I love your videos. As always, thank you fot taking tha time to make them

Dude I've been looking for a 30 Luger 98 barrel here in the US for YEARS and this dude has one buried under cat sh*t!

The science stuff at the start with the bullets was pretty cool and insightful! ty

i really loved the vice technic , deffintily i will use it! thanks for the great job!

Hey, another great video! All the best from the UK

My guess is that someone thought: "Where can I hide these guns that no-one would look?" and forgot the vital role that a ziploc bag plays in this scenario. I would probably have started by boiling the whole lot in bleach. Wouldn't have helped with the restoration, but they'd be sterile after!

Using the vice to apply force to the flat bit is genius ! Thank you sir

Have you ever considered a manual impact driver? I ignored them for years and drilled out so many rusted and swollen recessed screws in car door hinges and small throttle linkages. Finally around to using one and now its in the top drawer of my toolbox before I escalate the level of violence on a stuck or stripped fastener.

So many of the "restoration" videos are faked with "corrosion" painted or sprayed on a perfectly functional firearm. It's good to see a true expert at work.

Great video, as always.

Great work! Thank you for another interesting video.

These firearms look like the starter weapons of a rougelike videogame.

Even cats stay strapped

😭 Povera Beretta! Ottimo video, mai visto un restauro così particolare!

Excellent episode. Science and entertainment, what more could one want?

Not sure that this is what *I* would call a "special treat". You're suffering for your art. But good on animal welfare for rescuing the cats, and good on you for rescuing the guns.

Great work and video!

Excellent, as always!

If I've said it once, I've said it a million times,... "I don't really know where rust ends and poo begins!!!" Classic!

I love how this project was: derust, beat with a hammer, derust, beat with a hammer, repeat

This video reminded me of the time that i had to help my mother (a real estate agent at the time) clean up evicted properties, one was an apartment in the worst part of town, the immediate danger was the rank stench of ammonia and yellow molded stains on the carpets...

Love the channel, you are like a gun scientist.

i can smell this video...... i used to have an aunt who was a hoarder and hoarded cats as well so i know this smell VERY well. Good on ya for finishing the project

Great as always, thanks! RIP the bernardelli..

After months of not touching my Beretta I decided to take it out of my gun safe tonight and rack the slide, check the magazine, and just marvel at its beauty. It’s a 2016 model 92FS. And then just minutes later here I am randomly finding your video of you bringing one back to life. They’re great guns, I have a video of mine on my channel along with 2 other Beretta models. They’re great guns. I enjoyed your video.

13:40 I found that laughter extremely relatable. I often find myself chuckling in disbelief when even the smallest things in a large problem don't work as expected.

you are a credit to your profession. Thank you for the video

The Bernardelli might have been a good subject for electrolytic rust removal, since it even removes the deepest rust pockets. Normal citric/phosphoric acid bath is nice for removing surface rust, electricity and hydrogen cracks the rust even from deepest corrosion pits.

The "canon au pipi de chat" caught me off guard haha

I learned very much about electrolysis from this video, thank you.

There's an old expression: "Cat got your tongue?" - in this case it's "Cat got your pistols!" Both left me speechless! Amazing how destructive cat urine/excrement is.

Ciao, Carlo. Excellent video. I sincerely hope those serial numbers don't throw any distubing results. Loved many of the one-liners you pulled on this one. Sad to see the Bernardelli in such a state but two out of three is no mean feat. Truly amazed at how corroded some of the aluminum areas were. I knew of a local case where an ex-con wrapped a big iron in a used baby diaper and into the trash bin it went. He'd used it for a couple of robberies but got ID'ed. Police came to his house and found it anyway. Hilarious and disgusting, Cheers.

I have nothing with guns but as an engineer i find these video's awesome. Great explanations!

The best firearm restoration channel on YT! Have you ever tried Evaporust or MC21?

Watching you work on the Beretta reminds me that I need to clean and oil my Beretta 1951. Hopefully you have the opportunity to fully restore these guns after the case is completed.

Well, two out of three was a pretty excellent result in this case! What an amazing and diligent recovery. I think most people wouldn't have even tried. You could have written a thesis on this.

You are an absolute wizard, man. I thought those guns were done for

Fascinating stuff!!

A.K.A. "Le pistole ar piscio de gatto"

Oof, I can smell this video 🤢🤢 Nice work as always!

Extremely interesting. Thank you!

What's the difference between your rust bluing and the cold bluing solutions that are commercially available? Just curious. I have no experience with these things. Sorry if you've explained this in other videos

You know this man means business when he skips the "I didn't ask" entirely and goes straight to the "it can't be tight if it's a liquid" torch for a stuck magazine.

I can only imagine how bad that litter tray of delights must have smelled! Nice work getting 2 of the 3 functioning again :)

I pull my phone out just to see the notification for this now I’m watching it in class lmao

That smith and Wesson revolver was made right down the street from me in America haha interesting videos sir, have a nice day

Sculpturing in sh**t :) This is the only restoration content related channel I respect and subscribe. Thanks for sharing your knowledge. Good job!

Your French pronunciation is quite good. As a Canadian, this video hits close to home, as the devastation of salt rich solutions on exposed steel is visible every winter. Corrosion is the price we pay to prevent collisions.

I know you wont see this but the way you restore the firearms on your channel have stared use it you have save a lot of historic firearms I own from scrap I just want to say thanks

"I don't really know where rust ends and poo begins to be honest." Not something I thought I'd hear today 😂

great! i learn a lot with this videos. thank you!

The uncommon and often forgotten S&W model 65, which lived in the shadow of its more popular brother the model 66, and its mighty cousins of the model 686 series, found wallowing in feline fecal matter where it was abandoned long ago. Very sad.

I love that brilliant blue of copper nitrate on some areas of the the cartridges.

really cool....thanks for posting

I live in Texas and my step father served in the marine corps. If he were alive and saw the condition of these firearms he’d certainly have a stroke. I’m glad I was raised to take very good care of my firearms.

It is so impressive/ somewhat scary that you (or whoever) actually fired these after all the damage they had. It shows the resilience of these tools (weapons). And the fact that it takes someone of your talent to even get them to a “functional” status makes me feel safer. Because the likelihood of the common person doing this much work to try and get these working is just not going to happen except for maybe in the most extreme of situations.

Nice video, I hope you do a restoration on a Type 99 Arisaka one of these days 👍

2:18 EPIC! A shout-out to Nile Red is always proper form!

love your vids man

This video had taught me 30 new ways to describe cat excrements and I'm not sure what to use this knowledge for

It is great to hear mention galvanic corrosion, SCC and hydrogen embrittlement. There are some others on KZfaq that are completely ignorant of that and what they do is downright dangerous

What makes your hands shake so much? I'm asking this because it happens to me too. Is this some condition that you have had diagnosed?

awsome video. keep it on

That first gun would send an actual Dane with a previously clean sheet straight to the prison for a couple of years: "Possession of a firearm i fireable condition" Other rules apply to Danes on paper only - they usually walk free or serve multiple sentences in parallel, when caught carrying loaded functioning guns.
