Making a Knurling Tool for the Lathe (Narrated)

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 almost lost is when you said “I make new one” the same way the text would appear on screen in most of your videos. You got the voice reveal out of the way, now it’s time to see that man behind this amazing work!

I still praise the day I found your channel in the depths of lockdown in a Melbourne winter! Thank you.

I honestly didn't think I would watch a narrated version of this video after having enjoyed watching the text version. However, I did watch it and was totally surprised at how much I enjoyed it. It was kind of a different experience from the first one. Nicely done.

I will forever read "I make a new one" in this voice from now on. Glorious.

[@SpookyMcGhee]

I work as a manual machinist and I can say without a doubt that this is one of the best machining channels on KZbin. Keep up the good work! Also the tool at 5:19 is called a dial indicator, probably other comments said that already but ya know :)

[@caribmedical57]

"I made a new one" is now my new ringtone. Yep, I am a big, big fan. 😄 The narrated video was a very pleasant surprise. I loved to watch the additional details. Keep the videos rolling! 👍

It was great to see you in action and hear you narrating. Very clear to understand and your slight swiss accent contributes to impart even more quality to your excellent work. And to think you went through all that trouble just to knurl a part for another video... a true perfectionist!! Thank you very much for another great video!!

[@casperjanssen5749]

I already liked the video in its customary format, but I love the narration as well. The personal touch of hearing your voice is very nice and I like to just turn it on as a background noise, somewhat like a podcast. I would certainly love to see (and hear) more of these in the future. Above all, I admire your precision and dedication to achieving a perfect result, not only in this video, but in every single one of them.

So interesting to learn that the knurling process is pushing that shape into the metal rather than cutting it. Never knew!

[@JeghedderThomas]

Amazing how the knurling tool works, I'd never have guessed this was the procedure - I always imagined that you'd have to sit with a tiny file and make each notch individually. I'm learning stuff.

[@fernandoqueirozpopovic7024]

[@capers72424]

I could listen to you say “knurling wheel” and “I make new one” all night long!

[@BradyBegeman]

The device you don’t know the name of in English is a dial indicator.

[@mymechanicsinsights]

Thanks

[@R2k2]

I’ve been searching on Haimer’s website for this tool, and according by their english section, it is called a “3D sensor”. But i guess that “dial indicator” is also correct.

[@christianlee1693]

I was thinking it was a pressure gauge(for hardness testing)

[@joelaldridge27]

A dial indicator is supposed to have a probe that only moves by one direction, this is a 3D taster ;) (sorry for my bad english)

The device is called a "touching probe". Haimer refers it as a "3D Sensor", Regards from a fellow machinist who learns cnc at 53 years of age and enjoy your videos so much! And a tip if i may. Drilling with a carbide drill you get your hole only 0.05mm bigger so you can skip reaming ;)

[@mymechanicsinsights]

Carbide drills drill very precise indeed, but too expensive for a home shop

Thank you for the narration it really helps us laymans (noobs). I always enjoy your vids no matter what your working on.

[@Azmaedra]

As an English speaker who also speaks German, your grammar and phrasing is especially charming because I often know exactly what German phrase you're translating directly into English: "Now I mill down the second side, that the edges of both surfaces hit each other." -> "Nun fräse ich die 2. Seite, sodass die Kanten einander treffen" or something like that (my German is not as good as your English.) Keep up the great work!!
