Making a Knurling Tool for the Lathe

- In this video i'm making a knurling tool for the lathe.
I needed to make a straight knurling for my „combination lock“ video on my main channel. I did use my friends knurling tool in a previous video, as it's good to have your own I decide to make one. I bought two straight knurling wheels and now I only need to make a holder for them to use it on the lathe.
The first thing I did was making a drawing of it with all the measurements and tolerances. Once I knew the dimensions of the finished part I could organize the material. As material I choose a heat treatable steel 36CrNiMo6 (1.6582). The good thing about this steel is you can't overheat it when hardening and ruin the hardening, as I'm just going to harden it with a blowtorch that's perfect. The piece was much bigger in the beginning than it actually needed to be, but that's no problem I'll just take a few cuts more and make some more chips. I got this part for free from my friend, so I was happy to get started. First, I turn the part to lenght on the lathe (120mm). Next I did mill it to it's dimension 20x25mm, once I had this done I took out the step 5x95mm. Then I milled the slot for the knurling wheel. Once I got that I only needed to make the hole for the pin and cut the thread which will hold the pin. After the machining I did the heat treatment. Heat it up to around 800°C (cherry), hold the temperature for a moment and quench the part in oil. After that I needed to temper it to take a bit of it's hardness and stress away. Because of the high temperatur of the quench the part turns black, but it won't stick properly and start to peel of. So I cleaned it all up with Scotch Brite and then I used the bluing liquid to give it a nice and even black finish. The final test worked very well. By the way, I didn't clamp the knurling tool 90° to the part, I clamped it at 91°. This way only the right edge of the wheel will cut to the final diameter, which gives it a much nicer finish.
I hope you like my work and the video.

I hope you like it :-)
No entendí que utilidad tiene.
@@mauricioandresdeleonetcheg384 si hubieras visto el video del candado del canal principal de my mechanics, sabrías que es una herramienta que fabricó para hacer moleteados.
Man ur Really Really very Hard work and great job👍👍👍👍👍👍👍 ur every video's I'm waiting with out food Really man ur 100% awesome👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏
How long is the bar were that you put the Wheel in
you need to feed more with you flycutter
Milling and Lathing - for those times when you really, really need to turn five pounds of metal into four and a half pounds of shavings!
A perfect meal! ❤
Yep
It's good for you. Plenty of iron.
You make it sound like it’s a bad thing dude
The faceless enemy of sharp edges.
An old friend of mine gave me some advise many years ago...he said, “buy the things you can buy and make the things you can’t buy”.
Funny story, in the online shop where i bought the knurling wheels they didn't had the holder for that specific wheel. All the holders they had were for smaller wheels, but i wanted the big ones.
@@mymechanicsinsights Would you kindly point me to where you buy your tools? I am particularly impressed with your files, taps, deburring tools, as well as reamers, and drills. Seems Swiss quality- hard to come by easily in North America or it costs an arm and a leg for the home shop.
Made your own knurling tool which did the job for the combination lock. You are a PRO!! Trade schools should watch your videos for learning.
I’m sorry to inform you that from all the channels you follow none of them reach the level of percision and detail you bring in your restoration. Ty for such beautifull work!
Thank you very much, appreciated :-)
Check out clickspring
You really are obsessed with smoothening the edges!!
Haha indeed :-)
@@mymechanicsinsights I think it's great. Shows a real appreciation for the aesthetics and not just the functionality of the part.
@@gerathys I personally prefer sharp perfect edges but I respect his attention to detail.
only real mechanics pay that attention to break the edge!
Good machinist always breaks edges/burs. Professional
Watched the "talking movie" first, now the "silent" version. Loved both!
Just from seeing your dedication and impeccable quality of work, I can tell we would get along very well.
He clamped the tool at 91° instead of 90°!
Man, you are really out of this world. Awesome work, as always. 😊
I tried with 90° first but the pattern came out much nicer with 91°
I got a like and a comment from you! Now I feel like a celebrity! 😄😄😄
I literally stopped what I was doing to watch this video. Great work as always!
Haha thank you very much :-)
Nicely Done Bump knurler! Quality knurling wheels, worthy of such a tool. Most precise hand removal of burrs and sharp (blood letting) edges I've seen or done. Man, I love those files you have! Symmetry was outstanding! Chromoly (4340) is nice to work with but sharp as heck! Thanks for the tool build!!
Would you be interested in making videos that detail the preparation and aftercare (cleaning the machines, etc) of your videos? I love the video you've posted, we get to see behind the scenes, and all the work that goes into not only one piece, but the care that is required for the production of the tools that you use to create the final product, ie you made a whole new knurling tool, for the purpose of the construction of another piece. It is incredible how much time and effort goes into these videos, keep up the great work!!
Yeah maybe, thank you very much
That's a great idea! 😃
I love that you always file down your sharp edges. The final product with all the edges beveled looks so satisfying. I also like that you take the time to go through the comments, even though you have so many to go through.
I try my best, thank you :-)
Excellent work, as always! I think this "insights" channel is a great idea. Appreciate your work, thanks.
Best restorer out there by far. I tried watching someone else’s restoring videos and it wasn’t up to par. I’ve been so spoiled by you.
Perfect combination of an artist and a metal worker
Fantastically well shot and arranged and honestly gives a very good insight into just how complex and time consuming a 'simple' piece can be to make. Really love your channel. I'm not a machinest but you really make me want to be one!
Yeah it's cool to make parts and see them work. Thank you :-)
Excelent work. It´s absolutelly perfect.
Good material for this can be also old cracked cutting tool from lathe (I mean holder of carbide plate).
- ideal shape and good material
I made all my holders of knurling tool from this material and for home using is OK.
Don’t we all have this one friend that gives us steel bolts for free?!
I hope so ;-)
Great idea, letting us in on some more of the detail. A delight to watch, as ever! :-)
Thank you :-)
Dein bewundernswertes handwerkliches Geschick und liebe zum Detail lassen mich immer ganz gespannt auf das nächste Projekt warten.
Man spürt richtig das du da Bock drauf hast👍👍
There is just something so satisfying about nice and shiny metal.
Very nice, I had the opposite problem today, a knurling tool and no straight knurls, maybe I'll post a video... (ps, looking forward to the narrations 👍👍)
Beautiful work, thanks for showing it to us :)
I not only learn a lot, I also feel relaxed and well meditated after your vids. Cheers!
Thank you :-)
Can’t wait to see this in action! :)
I honestly didn’t notice whether or not there was narration. The steps you took were very clear and adequately demonstrated. Very well done!! My personal issue is any video where the maker spends too much time talking at length about what he’s going to do and the decision process he went through for his design before he finally starts doing it.
You're good! More, more, MORE!
Perfect. Great attention to detail! Another masterpiece to your collection! 10/10!
It's nice to have my own knurling tool now, thank you very much :-)
I wanted to copy this idea but ended up welding bearings into the inner guts of a ratchet wheel and utilized a u-bolt to make a similar idea. 72 teeth ratchet wheels get the job done. Who would of thunk?
Phenomenal work. I didn't even know one could make a tool like that in a shop. I thought they make such a tool in a factory and never expected it to look as simple as that either. That makes your work double cool. Thumb up
Привет! Приятно наблюдать за вашей работой. Красивые и окуратные получаются детали , и инструмент. Класс! Хорошие станки и оснаска. Молодец!
Spectacular. Well made and thought out. Still love the toys.
Beautiful!! I'm glad I found this channel, I've been a viewer of My Mechanics for a long time!
Superperfect again!!!! I love your jobs.
This new channel of yours is such a good idea. I love the intricate parts and now I can watch them all! I used to do a lot of machine work for my job, but don't so much any more so I enjoy watching someone else instead!
Thank you very much :-)
I'm pretty sure that you can easily step up your game and exclude yourself from other restoration channels by not just restoring old item's, but also "create" a more advanced, better looking replicas of what item you want to restore. I think that the "I make a new one" logo can be expand to a whole new level.
Yes indeed, i want to build more stuff in the future
@@mymechanicsinsights I've always viewed a certain similarity between you and Clickspring. Would love to see what you come up with in the future. You've gotten me, a woodworker, into metal restoration too 😄
I love your machining videos. You and This old Tony are my favourite machinists. Best content.
Amazing, I guess I never gave much thought to how knurling was applied to cylindrical shapes. Cool tool!
Seus vídeos são ótimos. Parabéns!
Simply wow
Amazing!! I love it 😍
another excellent video with all the essentials and no annoying music; well done and keep them coming!
Congratulations, very well your knurling tool.
Awesome work, all of your videos are amazing!!!
Great tool making skills! That came out nice!.
Thank you very much :-)
Don’t ask me why but I find it satisfying when you were painting on steel or metal or whatever it was
Nice camera work. Unusually better than the status quo.
Another satisfaction guaranteed video. Really enjoy you channel.
Thank you :-)
Incredible video as always! Can't wait for the detailed video
Should be up tomorrow or saturday. Thank you :-)
@@mymechanicsinsights Sweet!
Nice tool build we enjoyed this tool holder of those knurl teeth wheels.
Lance & Patrick.
Thank you :-)
Awesome as usual!
Excellent. As always Mr My. A nice finish on your skillfully constructed tool. And the finish your new tool gives to your project pieces is - not sure if there's a single English word for it - but professional + neat + functional + nifty comes close. Or that old phrase when you've done a job just perfectly and you stand back in admiration and say it's "just so!".
Thank you very much :-)
You can be very proud with your videos. Each video is a masterpiece. Great job. Keep making this kind of videos.
Thank you very much :-)
I love your vids..keep up the great work👍
When hands grow from the right place, good things come out. Cool 👍👍👍.
Когда руки растут из нужного места, получаются добрые вещи. Классно 👍👍👍.
Perfect as always. Im wondering how do you recycle metal shavings after the restoration or creation?
Yes of course
Clean and deburr your part and vise before reclamping. Also, that face mill was rubbing/grinding rather than cutting a chip. Run it harder/faster, and if your machine can't take it, use a different tool. (Or possibly change the inserts) also, sand the black oxide off after heat treat, so you can see the color change when you temper it. Just feedback. Love your videos.
The mill was already running at max feed. The tool is a bit too big fir it. I know how to mill properly, but this is just homeshop easy going. You need a proper machine and also cooling is good to have. Thank you
No one is saying you don't know how to mill properly but there isn't just one way to tackle a job, I've been a machinist for 36 years and I have learned lots by talking to my fellow machinists and I hope passed on lots of useful skills and info to others too.
You are another level!
I love behind the scenes ! :)
love it. beautiful feeds and speeds :=)
Nice! You made a masterpiece!
Great job! I like the work table with all the holes, that's sweet! You should do a shop tour ; )
Another outstanding out of this world video. You're channels and content are the definition of perfection.
Thanks lord :-)
@@mymechanicsinsights you are welcome :D
Beautiful work. Well done 👍👍👍
Just great, as always.
Thank you :-)
This is fantastic! Good mix of milling and turning. Great knurling tool! I like your videos alot!
Beautiful piece.
Good job mr. Nice workshop! Good luck!
very good ideas !
that is well made, what id expect from a high-end company . bravo sir
Very cool. Thanks
I did it to myself too. Only I have rolls with "ZEUS" they are carbide so I have a carbide axle ... Paw up ... Good job.
Muy bueno. Well done. You always receive a positive feedback. Saludos from Argentina
Thank you :-)
Can I just say this that out of all the other people who make tools or machinery work I’ve only seen you and Adam Savage use machining oil. Thank you for that.
Man, you're really creative!
Glad you like it :-)
Immer wenn ich von einem Einsatz mit der freiwilligen Feuerwehr zurück komme hast du ein neues Video hochgeladen, wie geil! Schon letzten Sonntag war das so😁
Nicely done !
Very nice tooling, always love the homemade tools. Great video, thumbs up.
4:51 just to let anyone who is curious no the name of that tool is a de-burring tool and is commonly used to smooth out the ends of pipes inside and out.
Great work as usual!
Thanks :-)
Hello You're the best of all the restorers. Good luck to you I signed!
When you watching my mechanics and quality drops to 144p
**rage intensifies**
Beautiful work as always. Although watching how long the milling took makes me glad I'm a woodworker 😆
On a bigger milling machine it goes much faster, this was maximum feed of the machine.
Fantastic.
Do you have to carefully set the distance between the tool and the part so that one revolution of the knurled part divides exactly into an integer number of knurls? I’m wondering how it magically aligns to a fixed knurl pitch without peaks on the tool hitting peaks on the part. Hopefully this question makes sense - would be easy to explain in person!
That happens automatically somehow, i don't know how it works, but it does.
Was the milling pattern on purpose? ;-) What caused it, chatter? Looks nice though.
This milling tool is a bit too big for this small milling machine, that's why. Thank you :-)
and possibly chips getting stuck under the cutter and rubbing the cut surface.
Hello, I am subscribed to both your channel ( normal and insight ). I love seeing you creating new parts.
That would be great if you could do a video where you explain how you use your machine tools ( lathe, milling ) to get the exact dimension, that would be very interesting.
Thank you.
Cleanliness is next to godliness.
Love the new channel just as much as your other channel!
Thanks man :-)
Very nice work. I’m going to have to make one. Great information
This legitimately made me laugh. I got these knurling wheels, time to make the other 95% of the tool to make them useable.
What a Professional Done...
Awesome mill work!!
Thank you
Good job! 👍
Thank you :-)
Very good! Perfect!
That Demmeler welding table looks gorgeous. If you don't like to share it's okay, but what kind of work do you normally do?
It's not mine, that welding table is at my friends workshop.
He is a CNC operator, if I remember correct.
@@zenddoor And what is a CNC operator? 😊
@@caribmedical57 Computer Numerical Control is basically a machine that you program to cut items into whatever you want and he is the one designing and doing the programming.
Молодец!!! Чётко до мелочей. Смотришь и получаешь удовольствие.
Congratulations !
Well done.
