Chris, I read an article a couple days ago about some recent discoveries about the Antikythera mechanism that mentioned you and your channel by name as inspiring the researchers.
Thanks Chris. However one thing I have never understood about knurling is the ability for the die to intersect each rotation with the exact same point in the items circumference, no matter what the circumference is. I just cannot get my head around how they interact together and pattern is seamless in the final product.
Well, that’s just the trick. Usually knurling requires you to have a set of specific diameters that correspond to the diameter of the knurling tool. Because the circumference is made exact, you can guarantee that the cutting piece will meet at the exact same point each time. A rope knurl seems to work the same way, its just a little more complex in terms of the diameters. I expect the contours and diameters of the stock need to be matched to the knurling tool. Pretty cool.
In theory, the object being knurled should have a circumference that's divided evenly by the distance between the knurls. But when knurling a soft metal like brass, it hardly matters. Imagine trying to knurl play-doh. As long as the pattern isn't unusually wide, the knob easily conforms to the tool and lines up perfectly after a few passes. (Non-vertical patterns also "self-register" better, which is one reason everyone uses diamonds and diagonal waves and the like.) All that being said, I bet Chris carefully mills his knobs to an evenly divisible circumference anyway.
Such elegance in a simple object is a mark of craftsmanship. You have made me a better fabricator and my interest in horology is thanks to you as well. CHEERS!
I imagine your lathe's bearings take a deep breath and brace themselves whenever they see knurling tools approaching. 😁 (I know that knurling brass is easier than steel, but it's only a wee lathe, after all...)
Chris-can you point me to your best video describing your sanding/mirror-polishing technique? What grits, water or not, and movement pattern (figure-eight, right?) do you recommend?
How to keep the shiny of the polished brass for long time? They will oxide if exposed to elements, right? Do you consider metal plating them after all this beautiful work?
I don't really have a "use case" I could argue to convince myself to buy a lathe, but just watching these sort of projects makes me want to buy one, even if I just end up hanging washing off it :)
Since you already take everything to a mirror polished finish, have you ever considered going through a couple of plating steps to help keep things from tarnishing?
Remember to brush your knurl tool twice a day!

I was so chuffed to see your name linked to a scientific paper in the news this week! Thanks for being a diligent hand filer!
oh interesting! what paper?

It was my understanding that this isn't the case and your knurl circumference needs to match what you're knurling.

There is a good Joe Pi video about knurling and diameters
@@stevenhintz5508 Thanks Steve, I'll have a look at that later

Such a beautiful knob/knurl! 🤩
I saw you mentioned on Ars regarding the antikythera mechanism.
More comments about your work than about the article! 😂
always a good day when a Clickspring video arrives. thank you
Each piece a work of art.
Your creations are more like jewels than mere projects. cheers!
Just amazing! I don’t know if I could afford the knobs for my home but gosh they are beautiful 🤩
This takes machining to the level of art!!! Excellent work!!!
Now I need to make a toothbrush holder to go beside the knurling tool mount.
I recognize those YG-1 drills. They are my favorite as well.

More impressive machining and beautiful part. Looking forward to the next video.
Beautiful ! very tasty 3 minutes. Thank you

Utterly amazing.

Does the rope knurl work for any diameter part, and line up or does the cutter need to be matched to the diameter of the part.

Everything looks so clean and perfect that it looks CGI. 3:20

I’d really like to watch Chris doing some plating like that, I’m sure it would be interesting.
👍👌👏 again and as always (video and work). Best regards, luck and health in particular.
Pretty cool.
I haven't seen this type of knurler before. It doesn't seem to be for sale as commonly as regular knurlers. Did you make it?
Hi Chris, What is that hand-held turning called you do on the top? what do I search on youtube to lean it. I keep getting woodworking videos
pretty!
bravoo
😎✌️
just beyond yaw dropping
Why doesn't it cost much to hire birds?
Because they're really cheep.
Ooo, first 😂
