Knurling from two Sides - The Perfect Knurling
ฝัง
- เผยแพร่เมื่อ 4 ต.ค. 2022
- In this video I'm making a big shaft with a knurled section in the middle. This footage is from a failed restoration video recorded in July 2021. I cancelled this restoration of an old and very rusty 25kg dumbell that was sent to me by a subscriber from Germany. I thought I could still share the footage of the making of this shaft, because it was very special to knurl from both sides with an overlap. I've never done or seen this before anywhere. One very critical point for a successful result is definitely the runout. The part has to run 100% true on both knurlings. Therefore the only way to achieve this was to turn the part between centers. As I don't have any lathe dogs in the shop I decided to fix the part with a dead center with a threaded shaft. Like that the part was running true and was also secured. The knurling went very well and was looking really perfect, also the overlap was almost not visible anymore.
I hope you like my work and the video.

That centering is so smart! The threads only provide compression, and the cone provides alignment. Very cool, will file that away.
A center drill type B would actually work even better. Then your dead center angle wouldn't run into the thread. Also for heavy machining it might get tricky to get the part loose again.
Видео вышло 2 часа назад, а коммент оставлен 6 дней назад. Че за херня?
@@ugryumiy Patreon backers will get early access to videos.
@@mymechanicsinsights add a nut/washer to the grub screw and use that to lock the part instead. Now a spanner will break them loose easily.
And it's aligned with the chuck jaws, which is where your concentricity is lost. I can't think of a good reason to do this.
I’ve always wondered how such a perfect pattern gets etched into metal when I use barbells for working out, I feel satisfied now that I finally know😂 awesome video
Iam pretty sure the lathe Jedi is making his Lasersword now. Handle done - superb job!
May the knurl be with you, my son
@@mymechanicsinsights well played 😄
@@misterpatina I so love it when TH-cam creators support each other. Kudos to you. You're both awesome 👌👊
@@Psammead21 thanks my friend!
I loved this when you showed it last year. It looks amazing. I can't find the words to describe how interesting and fascinating this stuff is. Thanks, MM.
Thank you very much Vickie. I remember being very proud of that part when I made it. Very unfortunate I had to cancel this project.
I like the MM nickname. Must mean hes sweet 💗
@@maggs131 🤣🤣
@Hatem Raafat No, this was from a restoration of a dumbell he abandoned.
@@maggs131 his videos are eye-candy.
I love when you do things my shop teacher said were impossible.
Like turning wood on a metal lathe. My old German-trained metal shop teacher would have had a heart attack if he’d seen me doing that.
Phenomenal work. I love the optical illusion that appears over the knurling as parts pop in and out of shadow - it really shows how precisely you got everything aligned.
Now , this is a knurling 😍
So soothing to watch. A massage for the eyes and the mind.
Anybody else holding breath not to disturb him when he did the overlap? This was so satisfying to watch!
I held my breath for 6:29
@@simplyed9482 🤣👊
This is a long way from initially making the knurling tool for the lathe. There isn't another restoration channel that comes close to MM. Keep up the amazing work.
Beautifully done knurl. We're fortunate enough to have a dedicated machine for knurling. We drop the part into a fixture (no clamping required) and the two 140mm wide knurling tools knurl the shaft in a couple seconds. But then again we're talking mass production so it's apples and oranges. In any case, your knurl looked fantastic.
I've always found knurling to look classy, especially when done on smaller tools. Well-done knurling just kind of adds an air of elegance.
top tier looks for sure
I literally talking to someone last week that i wanted more knurling from my mechanics, you answered my prayers!
... was* talking ...
Another 'perfect' piece of precision machining, the overlap was simply amazing. Well done!
kinda hard to mess up, actually, since it's timed by the lead screw.. you can only mess that up by turning the carriage handwheel instead of running the spindle in reverse to get back to the middle after flipping the part
@@klchapman554 He's not cutting a thread, it's not at all timed by the leadscrew. The knurling wheels naturally catch on the existing knurl and follow it.
Love the knurling, beautifully executed.
There's a superfluous word in the title. Everything 'my mechanics' does is perfect. As always, thanks 'my mechanics', you are the pinnacle of restorations.
It's always a pleasure to watch a master at work!!
Also, that's a fantastic solution for turning between centers without worrying about a laythe-dog getting in the way.
First time I have seen knurling technique. Very unique. Thanks ⚘️
When "The Perfect Storm" came out, I swore I'd never take seafood for granted again (and I haven't). MM has given me new eyes with which to appreciate the thought and skill that went into the manufacture of my own humble tools, whether it's a sewing machine or a screwdriver. Thanks MM!

Beautiful work, as always.
that is amazing work. i could watch these all day
Always a pleasure to see the knurling process & New knurling, easy to say when sober🤣, thanks for sharing that upload!🏴
I had no idea what knurling was. Pretty neat. I'm learning so much watching this channel, not that I'll be able to use the knowledge. But it's fun learning stuff.
Love the work done on both of these channels, 👍
Turned out gorgeous!! 🎉🎉
I started watching your channel a little over 2 years ago, with no knowledge of lathes, mills, bench grinders, or much of anything else. Initially I thought that the lathe was operating with a computer program because it was so precise, but my brother informed me that that was all manual control. The precision of you manually shaping metals or lathing them blew my mind! But it turns out that you are Swiss, and thus your amazing skills are hereditary and passed down from generation to generation! The greatest mechanics experts in the world!
Your content is amazing, I am really happy discovering your channels! Wish you all the best and thank you for sharing with us
Another amazing piece of work...Excellent 😉
Knurling is pretty darn cool. Great video work!
I don't know the reason why you never released the restoration of the dumbbell. But even "failures" can teach us a lot.
We all fail with our efforts from time to time, and I think it's important to acknowledge that it's OK.
My thoughts exactly. Every failure can be a lesson.
Would actually love to see a failure with reasons why!
'my mechanics failures'. I'd watch that channel.
@@Drakhra unfortunately it's just a channel with no uploads lol
I can't see what the failure was, looks great to me....just my opinion....
As usual....PERFECTION!
Exquisite finish, a genius at work. Amazing 😊👍
It turned out perfect!!! Awesome
Beautiful!
Fantastic job 💫
That's an interesting knurling tool! Ive never quite seen one like that at a 45⁰ angle before! Lovely job as always. A failed project or two is still a good thing, every day's a schoolday in the workshop!
we have one in my shop to, it´s a knurlcutting tool and expensiv af (like 50 times of an formtool ) but the outcome is great and you can cut up to 2mm deep
I never thought to use a straight cut knurling tool on an angle. I bought a few patterns, bit of a waste haha.
@@ZeppSiros that´s the way how they cut. for straight lines the wheels have an angle
@@janzweitweg2927 do you know the name of the tool that you have. Struggling to get the depth I need with a traditional tool
Incredible !
Even his experiments are perfections!
Really amazing work, dude! It looks fantastic! 😃
Stay safe there with your family! 🖖😊
Incredibly satisfying
Every shop should have at least one lathe dog.
Неудачные реставрации тоже интересно, зря не выложили, тот подход с которым вы подходите к реставрации очень увлекательный.
Wow! That was amazing.
Beautiful surface !!
I love this type of videos...so satisfying...who needs the nature sounds ...
Beautifully filmed...
Mesmerizing and amazing
Nicely done.👍
So cool! Double knurling! Love the very clean overlap!
In all my life, I have never considered how this is done. Very interesting to watch, thank you.
Great work! Thank you for the video.
Meine Mechaniker was here 👏
Beautiful
Ingenious solution!
very satisfying 😍
It is exceptional!
A work of art.
I didn't even see the channel's name, I just saw the thumbnail and thought "oh that's some perfect knurling right there!" clicked, and of course, who else could it be?
The process of manufacturing, building, repair or simple troubleshooting is just fascinating to me. Probably why I chose to be a mechanic hahaha. This demo was incredible!
Perfect work
Amazing work!
Sad to know there's My Mechanics content we never get to see. Such a beautiful bit of work though. :)
Took me a while to see the 2nd knurling wheel below the top one and was wondered before, how you could do the cross knurling in one pass... ^^*
I think this is gnarly
Great knurl dude
Always loved knurling
Very cool. enjoyable viewing, thank you.
niceeee. who doesn’t love a good knurl
you have some serious talent
that turned out real nice man
That's some nice knurling right there
This gave me the tingles
What are lathe dogs? Also, why did you have to start the knurling in the center of the handle, rather than at one end and then knurling continuously to the other end? The result looks great either way, I don’t know much about machining so I’m just curious if there’s a reason for this particular order of operations :)
Came here to ask exactly that
Same here. I’ve heard the terms “dog & dogs” used as a name for various elements of machinery parts before but not as part of a lathe.
It's a simple clamping device. It has a hole in a block of metal with some means of screwing down something that is in the hole like a bar you want to turn. Then there is a handle sticking out of that block which is bent 90 degrees and that tang is positioned so that some part of the chuck or face plate can drive it such as a chuck jaw or slot in the face plate. The driving end is fitted with a center cone called the live center and the other end is a center in the tail stock. The whole system is called "turning between centers" and it has several advantages over turning in a chuck such as turning a taper with offset tailstock, the ability to remove a part and replace it exactly where it was etc.
@@billshiff2060 thank you. I think I can visualize that. I know it’s not an easy concept to describe using only words
@@paulbush7095 No need to imagine it, just search it and see the pics and vids.
Immaculate!
My brain feels so much better after watching this.
Nice solution for driving w/o a lathe dog. Like to see more detail on the pinch knurl tool. Thank you for sharing.
Thnx again my mechanics. We love you ❤
Knurling - man muss es einfach lieben! :-)
So soothing
Started in 1971 finished in 2012, turning handles in my garage for fun now!
that was beautiful thanks.
Satisfying af.
Amezing work👍
Good job mister well done
Creative video,thanks :)
Absolutely beautiful and mesmerizing process. Thank you for sharing!
Nice sharp knurl. It looked easy to pick up the existing knurl when you did the second half.
Great work sir marvelous
Hat's off great job my dear brother ❤️👍.
Imagine those knurls on weight bars in the gym - the grip would be fantastic!
I still have no idea how or why knurling works but I'm here for it.
Wdym its not hard at all tbh
Kind of magic!
Amazing. You should have taken it home and put a logo on each end of the bar. Nice job bud!
Excelente proyecto muy bien desarrollado y mejor ejecutado, unos magníficos mecanizados maestro, gracias por compartir sus conocimientos y experiencias, un saludo cordial y por supuesto un gran like desde Narón (Galicia) 👍🤓😜
I'm not entirely sure what I just watched, or why, but it was fucking fascinating. Thank you!
Great job, I love these workers very much. I work in a similar field in the Bearing store
The knurl must feel amazing to the touch
Very cool. I had no idea how knurling was done, but I wouldn’t have guessed it was with a live spinning tool. I’d have guessed several helical grooves in opposite directions.
Yeah it's literally just a metal profile that spins that is then pressed into the material leaving behind the profile on the surface of the material
Absolut amazing Work and a so very cool Idea Love it Daumen hoch da lasse habe den Beruf gelernt und die Idee ist echt Hammer 👍❤️👍
years of experience can create a beautiful stuff
