1930s Rusty Metal Shear - Perfect Restoration

- In this video i'm restoring a Beverly Shear model B1
My friend found this Beverly Shear in the steel waste at the recycling station. When I first saw this Beverly Shear I had no idea why it has such an unique shape. After a bit of research I quickly found out that this is a very well known tool. So I decided to restore it and bought it for $30. The Beverly Shear is a tool to cut sheet, because of it's unique shape it enables you to cut curved shapes and that's what makes the Beverly Shear so special. The Beverly Shear was invented by Kurt Nebel in 1931 in Chicago. There are 3 different sizes available: model B1, model B2 and model B3 which is the biggest one. They have made some changes over the years, but since 1947 the shears have remained virtually unchainged. For the colour i decided to use a darker grey than the original and choosed anthracide, I also added two washers. To make the parts black I used a bluing liquid called „Birchwood Casey - Super Blue“ and it worked very well. It's easy to hanlde and the big advantage over heating and quenching in oil is that you can do it without heating the parts up. So you won't change the structure of the steel and you can use it on hardened parts as well. Because I have no tools and experience in sharpening such blades, I decided to ask my friend Philipp Elsener from Elsener Messerschmied to do it. He's a professional knifemaker here in Rapperswil Switzerland. Check out his website, linked below. Overall I'm very happy how the Beverly Shear came out and as it is such a unique tool I'll keep it for myself.
I hope you like my work and the video.

My mouth has fallen open and I'm drooling, transfixed at the absolute mastery of the work you do. In every industry there is a benchmark. In the restoration industry you and the final products that you put out are that benchmark. Some people perform tasks and execute skills well, what you do is artistry. You are a master craftsman thank you for sharing your vision of perfection with the world. No music? you don't need, it the sounds of your work and tools are music fitting to the artistry done here, your editing is phenomenal with no fast motion photography just the steps it took to get the job done, the time spent doesn't matter it shows in the final result. I am forever grateful that I found your channel don't change anything.
Thank you very much :-)
Oh yeah... there is no music... i must have been too tensed to notice.
Those ribbits screaching in tension: "will it break? Will it hold? Just a notche! A bit more. Must make sure it will never slip again" Just like nipples, so squiky clean! Nice finishing!
Srry... i complicate what I have to say. Hope I didn't gave away my dirty mind xD ...
Look! it was tense alright?!
Edit: gigaddy! Xd
I really like "no music"! Top!
@@mymechanics Deine Arbeit ist wirklich erstaunlich. Vor allem auch die enorm smoothe Videobearbeitung setzt dich von anderen Restaurateuren ab, und macht deine Videos noch viel sehenswerter.
I agree 100%
Please restore the sand blaster button.
And the gloves.
My God the sand blaster button is so so frustrating to see, out of all the immaculate equipment in that workshop and BOOM broken button on the sand blaster..... So annoyong. Take nothing away from his truly masterclass work.
HA!!!
Bitchers!
He blurred it.
the fact that he uses this specific shear that he restored in his later videos to cut metal makes me quite happy. channels like this first got me into manual labor, and i like it a lot.
Nice to hear that, thank you :-)
i'm pretty sure that's the gressel vise from an earlier video, also.
One of the coolest things about this vid is, that the Shear still appears to work after 90 years... before any restoration... now that was quality in manufacturing.
Yes, also that he uses this shear in his newer restoration videos is pretty cool
Back when stuff was made in America
@@basedbane787 It's still in production
@@maplebones nice
Part of that is due to the simplicity of the construction, fewer moving parts means fewer points of potential failure, and when you consider that it's built for a very singular purpose, that simple but effective design is easier to get away with. It also helps that it doesn't have any wood or plastics in its construction, which would degrade more readily, and was predominantly made from large, solid cast metal pieces, which by their mass alone have some resilience against meaningful degradation of function by the surface oxidising. The main points of potential failure would be the pivot point bolts, which could just as easily have been locked up by rust and rendered the whole thing inoperable if lady luck had been less kind.
This is not only the restoration, it is improvement! Casting edges removed, sharp edges too, parts alignment, etc. It looks better than when it was brand new! Awesome work, thank you for sharing!
Couldn't agree more!
Absolutely unreal work, and I love your style too. No music, no sped up footage, just quick cuts (even to minor things like switching off equipment). It's like the build is being told as a story. Utterly fantastic.
I have to agree. The format is perfect. Anything more or less would make this channel less special.
Yes indeed. I love this style of video.
Exactly my opinion! No fast forward in the videos, no hurries...just the real work wich is needed, to get the job done.
Keep on this way!😊👍😊
After sanding: "Ooh shiny"
After polishing: "OOH SHINY"

I dated Beverly Shear back in high school. She was very sharp.
Ha
Let me guess, it was in Chicago!
Was she up to the legend?
Bah-dum-bum!
lol
I am 80 years old and I discovered your channel recently. I love to watch you working. It's so beautiful what you do. Perhaps I like it so much because my husband was a tool and die maker and engineer designer. He learned his trade in Germany. He is now 90 years old. Thank you Sara
There is only one imperfection in all of your videos: the fact that they end.
It's edgy but it's true
Absolutely true I am not a fan of all of my mechanics videos endings I'm always wanting more
All good things have to come to an end, no?
I love how you don't show sped up sections. For me these superfast videos take you out of the moment. yours are much more relaxing.
I'm glad you like my style :-)
This isn't a restoration channel. This is a better-than-new channel
"Beverly Shear" - Sounds like the name of an old time movie actress. LOL
Lmao, brilliant brother
I was thinking more like a Broadway performer or dancer, who could cut some shapes (I'll get my coat) 🤣
Yeah in like an 80s movie or something
She was a very sharp actress. She really honed her skill. Her films were cutting edge. Anything but dull. I'll see myself out.
Close! You're thinking of Beverly Sheary.
Please don't stray too much from this video format. Using real old items, raw audio, nothing flashy but just regular edits and fine skill and you'll prosper. I was just looking at your channel this morning in the hopes of seeing a new video, and finally this popped up.
Agree... There is nothing more annoying having music destroying the process of the restoration.
@@EbonyPope yes that and constant blabbing and talking about some ridiculous life story, begging for money subscribers etc.

I'd watch a 20 min video of that.
I think every one of your restorations are always, "better than new"! And with many of the small fine tunings and removing of casting marks and sharp edges, you always do, to me, I think most of them are much better than when they were new!
And this one is a great example of that, with the sloppy handle being refitted properly, etc. What a joy these restorations are to watch!
There are a few other restoration channels who's work ranges from decent to fairly poor , but every restoration I've seen on my mechanics has been nothing short of absolute perfection ! It's a real pleasure to watch , thanks for sharing and keep the quality work coming 👍👍
"This screw is bent. Instead of just hammering at it until it's close, let's machine and polish a perfect replacement." THIS is why this is my favorite restoration channel.
Out of all of the restoration channels on youtube, I think you're one of the best. So much care put into your work - Thank you for your dedication!
Also the tools he restores look genuine old. I feel like other channels just leave new tools in the rain in order to have video material
I like how he manufactures some parts himself from scratch. Haven't seen anyone else doing that.
@@MrGuano11 "I can't repair this screw nor buy a new one - so I made one myself" ... I love this so much :)
This channel has spoiled me. None of the other restoration channels measure up.
I like how he used the correct tools for the job
Your simple improvements like the handle washer are why you set the GOLD standard for restorations. WOW!!
Nice to hear that, thank you very much :-)
A new shear is almost $700; this one has been restored to better-than-new! Great job, museum quality!
When this tool was originally made, the manufacturers said to themselves "ehh, it's a tool not a trophy. As long as it works, who cares what it looks like."
When you got finished with this item, it was a trophy tool. Your attention to detail is mesmerizing, and I like that you do not add music to the video. Not everyone shares the same musical preferences.
Over all, this was a most satisfying video. Thank you for all the labor you put into making it, and thanks you for sharing it with us.
-CacheRAM
I can only wholeheartedly agree with every single word you said, especially about his attention to detail. This is the absolute pinnacle of restotainment on UA-cam.
... und an den Besitzer des Kanals: Hochachtungsvolle Grüße in die Schweiz aus Österreich :)
@CacheRAM, I AGREE!
That shear is still made and Beverly is located in the oldest building still standing in Chicago, not far from where I was born. Magnificent restoration as always! Congratulations.
Bruce Boschek the knowledge on youtube is endless
It's actually insanely impressive how good it still performed before the restoration. They don't make anything like this anymore.
absolutely agree
I grew up about a mile away from the Beverly Shear Company. The building was up for sale as of December 2020. Great work!
I watched the whole thing, beginning to end. No skipping. I enjoyed every second of it. Metal work poetry.
I even pause the video when it comes out some information text to not miss a second
Me too.....couldnt turn it off
Petition for my mechanics to show the whole sandblasting process bc it’s the most relaxing/satisfying part ever
It's relaxing and satisfying until you've done it from 9-5 and the weight of the hose and blaster starts to make your forearm ache. Don't forget the kink in your neck from trying to squeeze every second of life out of the sandblasting screens your boss never buys enough of.
@@nathannotimportant9379 they just meant watching lol.
In slow motion please so I can count every sand corn... 🤗😜🇨🇭
Prowler Cam where is this video!!!
At least the third time I’ve watched this restoration...you make it hard for me to watch other channels restoration videos with this kind of craftsmanship.
i don’t know how i got to this side of youtube, but i’ve been here for a few weeks now and i never wanna leave
POLISHING a lock washer!! Never saw THAT done before!! Attention to detail? This is a quality control manager's wet dream.
He's from Switzerland.... it explains a lot.
It's AMAZING! But 27:37 when he scratches the new paint with that burred edge on the sheet metal... I almost cried!!
Sameee
Ir broke my heart 💔
Tools are meant to be used, beating away, sanding away, scratching away the paint from a tool in use is the greatest honor you can bestow on it.
@@abe34fizzy
Or you could treat your tools with respect and not damage them.
@@101Crock trust cutting up metal and stuff without scratching the tools then get back to me, got nothing to do with care you pleb
Beverly Shears thank you from the bottom of their heart for restoring and improving their vintage product.
I have a Beverly Shear B2. I've had it since 1987 and it has been used almost every day for the last 35 years! This is an absolute must have for anyone that is into sheet metal work!
the best restorer of all time. It's the truth. Very patient, very diligent and most importantly-it does not accelerate the video... I will wait for the next project👍
In the motorcycle world, this would be a resto-mod rather than a restoration; these tools are now better than when initially manufactured.
me when i get in the shower: i start to clean the parts with the parts washer
🤦♂️
underrated comment. this had me loling
Chris Lawrence BRUH😂
Do you already have worn back issues by raising that "heavy duty parts washer" again and again ...?
Just freaked out my coworker by laughing at this totally unexpected and yet hilarious comment.
What is my life?
I audibly gasped with excitement when I realized this was the shear from many of your future videos. Super cool to know it's a tool you restored yourself!
I know this is an old one, but you do an absolutely beautiful job. Keep it up!
Glad to hear that, thank you very much
A Rusty lump of metal becomes a functioning work of art. Brilliant!
Every time I watch a video of my mechanics, I can't help but admire the shiny finishes, the precision in every step, the willingness to make his own parts... And yet the greatest question remains unanswered: how in the sweet hell does he keep his nails so clean and nice?! He must be blessed by the gods of manicure, however else he could have such nice hands and shapely fingernails. Somehow my mechanics manages handling pieces of dirty and rusted metal and yet retains those forever pristine paws... Teach me Master! Howwwww???
Just washing his hands…
Oh, and he can also polish his nails at 9:35 :)
Watching his videos makes me depressed because I realize I will never be as good as him at anything ¯\_(ツ)_/¯
You done it again my friend.
Peered restore.
What I like about your videos is the fact that you focus in on the job at hand without the need for self promotion or mindless chit chat.
Keep them coming.
Looking forward to the next one
I love how "I make a new one" has become a fan favorite thing
You have NO idea how much I appreciate that there is no music in your films. Just the sound of work - awesome
Brilliant job! The small details you record, like each bolt and screw... makes it worthwhile. Keep it up!
Thank you, i'm glad you like it :-)
Got a bent bolt. Screw it into something and unbend with a hammer? F this, imma make a new one, my tools are itching to build stuff
Damn, nuts and bolts brighter than my future
lol

Recently discovered this channel, and I'm completely hooked (or mesmerized, can't decide which). Not only have I come to savor the craftsmanship of your work, I've come to appreciate the care and discipline of your work processes. That you have a knack for recording and editing the process makes your videos a wonderful introduction to what the machinist's art can achieve. Many thanks!
[BTW, I googled 'Beverly Shear' and the firm was purchased by Mittler Brothers Machine & Tool in Wright City Missouri--and they continue to manufacture & service the Beverly Shear line.]
i think i could watch him fix casting mistakes all day… i love filing down metal, its so soothing
There are a lot of channels restoring old hardware and machines, but this channel is by far the best! You really take your time to restore with precision, dedication, eye for detail and pure craftsmanship! Compliments! 👍👌
Absolutely. The attention to detail is unbelievable! If something is broken or needs replace, he makes it!
It is pure Swiss craftsmanship we are lucky enough to watch on his channel. Our storyteller has learned how to expertly work metal. No wonder his nation's products are the best (and most expensive) in the world. He is a tremendous ambassador.
Thank you there are so many other channels getting way more view for such low quality restorations I watched this beginning to end it’s just a work of art I would love to shake your hand
SirWhiteCrayon Agree. Love when he polishes the bolt heads to mirror sheen
I would hug you if I could. Man what a masterpiece
Same here.. He really made a masterpiece
I don't personally get the constant removal of any and all sharp edges that aren't cutting edges, but I must say it is fascinating to watch. Always keeps me coming back. :3
I haven't seen ol' Bev looking this good in AGES!
That old stuff was built to last forever. In another 100 years when it gets restored again, it will look just as good.
"So I make my own." You know, like you do.
This thing probably looks better than it did to begin with.
I realize it's maybe a bit late as I've just discovered this great channel, but I wonder if anyone else gets the truly satisfied sensation after seeing this perfectionist complete one restoration after another, and realizing he is restoring pieces of history as well?...... just fantastic and exceptional detail in them all.......
Imagine the world full of experts like him.
By the way here in Chicago that company is still in business and that tools is still for sale for about 500 USD brand new
I guess they should see this video, gonna love that I believe)
Mt. Greenwood represent :)
They're still made the same way in the same place. I don't know why you'd assume differently. Lots of US companies make quality products.
@COLORS and TASTES Your comment was so unnecessary and uncalled-for. Congrats on useless comment of the week.
@@Sasasala386 not as unnecessary as yours ... not even close
Well... this tool surely looks a 100% better, and is a 100% better finished that it originally was. Amazing work.
What am I saying? 1.000% better!!!
I think this is the 3rd time watching this. Love watching you work. The king of UA-cam restorers
It always amazes me how many parts something has, even though it looks a lot simpler.
Title of his autobiography : "Removing sharp edges from my life" . Bestseller ever.
Has virtually no words
Life not usable? - I make a new one
Mr Alef:
This seems to be his life mission!
Maybe that's life is all about !!!
You give old tools a new life. That's quite a legacy.
This is what peak modern artisanship looks like.
I like that there is no music or talking, nothing to distract from the video. It's very calming and businesslike.
Your channel is the only one that I watch *ALL* parts of a restoration. On the other few, I watch bits and pieces and skip to the finish product.
Well done, bud!
Restore? It's better than new!!! Unreal! Well done young man!
Every time i rewatch these restorations im just amazed and pleased all over again. Man these castings are REALLY rough
Must be awesome to just go like: "oh I can't find this thing anywhere anymore, I guess I'll have to MAKE a new one!"
Haha nice restoration, really perfect!
@@MarcioSilva-fz2ch O texto em inglês no vídeo explicou que a graxa serve para evitar a ferrugem. E este equipamento necessita para funcionar corretamente da graxa.
I like the way they built suspense, I almost thought they were going to give up right there; this is my first time watching this channel so I was genuinely surprised when a lathe appeared. Well done!
I'm sure someone could find a replacement in a scrapyard, given enough patience. Probably more effort than making a new one though, and there's no reason to use an old screw if it's not going to be the original, better use a brand new one.
oh we all knew he was gonna make one anyway. we were probably all waiting for it too. i know i was 😁
in the old days, thats what everyone had to do
That sand blasting machine button needs restoration lol nice work as always
From a weak metal shear to a metal shear solid, fantastic
Another 50 years of life left in it.👍👍👍
Sharp edge: exists
my mechanics: wait, that's illegal
Dull surface: Exists
My Mechanics: wait, that's illegal
Something missing from item: exists
My mechanics: wait that's illegal also I make new one
I don't like how it takes and puts a beveled edge on a lot of holes like ... You don't need to do that, in fact it seems like they are just removing contact surface area at that point.
This guy out for a steak dinner. Waiter is like, "Sir. Sir. SIR, please stop filing the cutting edge off all our steak knives!"
@@SteelOfLegend They actually usually do the opposite. Since everything is a spring you only get good contact at the edges of the holes. By beveling it you increase the circumference of the hole and thus the length of the edge of best contact.
However, I don't like how he must make everything shiny. It's neither authentic nor is it beautiful. I just makes everything look less precise and more bulgy. That's a personal taste of course.
Sir, I know I'm only the millionth person to say it, but you are amazing. The patience, care, skill, and love that you bring to these projects is just inspiring. Thank you.
What a nice job you did on that machine. thank you for sharing with us.
My pleasure :-)
It speaks to the quality of the product that even before the restoration, it could still do it's job right.
I love the honesty. It was nice of you to give credit to your friend. It's not like anyone would notice that it's not your hand sharpening the blade.
yeah it was so sweet man
Always looking forward to your videos mate. No blah-blah, no music, simply craftsmanship !
This is supposed to be a workshop tool - for cutting thin sheet metal ...... by the time you have finished with it ....it could be an award presented for excellence in engineering or something !!
Lovely Work!!
Glad you like it :-)
Good tip about crinkling the foil to fill the holes before sandblasting! Even though I believe I'm quite thorough, I always learn something watching your videos.

Same here, brother
I guess you could say this video is shear perfection 😌
I come back to this every now and then
No talking no music, perfect!
I like it. There is no music, just a sound of tools. Great job!
This is like watching Clickspring (YT channel) but for tool restorations! The level of details and dedication of getting the smallest stuff shiny is just awesome. Well done!
(Ps, if anyone hasn't checked out Clickspring, I highly recommend it.)
Мужик, ты лучший! Такую вещь вернул к жизни.
Not putting music on your videos has doubled the beauty of your work. Well done and thank you for sharing your works.
I cannot get over how insanely good every aspect of your videos is. firstly you hands down have the most complete and perfected restorations of any youtube channel, I love how you have no obnoxious music just the wonderful sounds of the metalworking process and your editing is flawlessly entertaining and reminds me of another fantastic channel"Primitive technology". please keep up the fantastic work as i will watch every single video you make,
Ha, reminded me of that channel, too xD
my mechanics restoring a destroyed T-34 tank: -"The turret ring is busted. I make a new one."
He would do that.
Watch a tank restoration, I've seen them clip the front half of a tank hull to the back half of another tank through the turret ring.
cannon hole has a sharp edge I will chamfer it.
That would be one shinny tank
The frontal plate is a bit rusty, I'll add on some weld material *adds Switzerlands entire reserve worth of welding material*
I do like talent and pure devotion in all kinds of work.
when I was doing my PhD about 38 years ago my supervisor and later one of my best friends tipped me off my study and forced me to stop researching and he used to say it is not a noble prise work it is merely a PhD. and ever since he accused me of being a perfectionist.
Well done.
This gentleman is a metal working wizard.
The editing of these videos are superb. I didn't think I could sit here for 28 minutes watching you restore this tool, but you seem to show us what is needed and move on to the next step in perfectly timed segments that make watching effortless.
I started watching and thought it was ridiculous. The shear already worked, and the best you could do was clean it up and maybe paint it. But you really transformed it. It is much better than it ever was. You are a true craftsman. I would be afraid to use it now, because it is more than just a tool.
you are right, it no longer is a tool but a work of art
I suspect it works better now than when it left the factory. That’s the genius of this restorer; not only did he clean and restore it, he also made it into a better tool.
For anyone wondering why he polishes the peices: its a type of rust proofing, if its a polish finish there arnt many places for moisture to collect + the polish itself is usually wax based adding an extra coat.
The beauty of rescuing old tools like these is now he has something “new” to use in his other restorations.
You attention to details is perfect, one of the best restauration videos out there. You can really see the amount of time and patience it takes for these. Keep it up man!
1. You’re incredibly talented
2. Your master skills are phenomenal
3. Sandblasting HAS to be therapeutic
4. The lathe draws me in
5. Thank you for your videos!
I worked in a place where they sandblasted freakish huge gears from wind turbines. It's the worst job ever. The sand creeps in every hole of your body. Can't recommend.
Sandblasting is definitely not therapeutic.
1. Visibility is low because you need to constantly replace plastic screens. Sometimes you can't see at all because your boss hasn't ordered the damn things and you're sandblasting on faith alone. This can turn even an easy to clean part into a very frustrating task as you're hunched over a machine for a long time.
2. Depending on how good of a machine you have it will clog semi-frequently. This goes back to the 'your boss hasn't ordered it' category; if you're too cheap to buy screens you're not gonna waste money on good, fresh, dry sandblasting medium.
3. Sandblasters kill themselves. The gun will eventually chew through itself, the hoses too. It will eventually eat itself away. This happens a lot slower depending on how expensive of a model you get.
4. Sand everywhere. Unless that's somehow your thing.
5. All these problems culminate together to a very awkward and frustrating experience where you're constantly trying to keep the machine running while cleaning parts and having nearly no visibility to see if the gun is even shooting sand at the moment or if it's clogged.
Yet 26:25 he uses a wrong size wrench.
Your early videos are - by far - my favorite in the collection.
You are a true Master Craftsman!
Fantastic work!
