Chris, the attention to detail in your videos is so apparent! I always look forward to you posting, despite having almost no adjacency to the subject matter beyond casual interest. I think that speaks to the accessibility you create for the subject. From one artist to another, thanks for putting in the work to share this stuff!
Hey Chris. I genuinely feel bad for asking because I imagine you get this same question constantly but would you mind giving an update on the progress of the Antikythera mechanism? I know you had submitted a paper for review and I imagine that is still pending but I wonder if maybe you could do a little video about what the finding was or even the process you had to go through to submit the paper. Sorry to be a bother. Love all your videos!
Hello mate - yes the paper was published a while back: th-cam.com/video/MkKgdq57uOo/w-d-xo.html More research and work to come on the Antikythera project in due course - Cheers :)
I don't know what might mean to you as creator, but on my way to work, i stopped aside to watch your video! You are the best! Thanks for spreading the knowledge.
Great series Chris! It's funny how in machining you often have to make a tool to make a tool to make a tool to make a tool lol and for gear cutting you go from a negative profile (radius checker) to positive (button or hss cutter) to negative (gear cutter) to positive (gear). You build up complexity of each subsequent step up to the final piece while maintaining accuracy of all previous features. Very satisfying even though I'm sure it makes it take quite a while to get to the finished piece! 😂
I really desperately want to be in a position where all of the amazing information you provide could be applied... I love your videos, and can't wait to see the last installment on this series!
unfortunately in 3000 years time no one will discover this video to see how to do these processes. it makes you wonder how advanced things were in the past but due to mediums of translations how stuck we become. I hope you write your own book on solid tabs of uranium or something. Great video
The little cone section you cut off of the end of the pinion blank looked pretty awesome. Like something a spy would throw down when people were chasing them.
first time watching one of your vids and immediately subscribed when i saw the handwork on the profile matching the gauge. ffs dude, ya got me! i said out loud, "awwww fack" when you showed it against the gauge. keep up the great work!
I really love your video's. Excellent content, editing, the way you explain. I wished all of my teachers were like you. I would have payed more attention.
Since you have made it, try the brass cutter on POM or Nylon. I would expect it to work. I made single use form tools for turning plastic out of 7075 aluminium and it held up just fine (and was much easier to machine than steel). Especially POM makes great low friction gears for low loads...
My favorite tooth profile is the continuous-contact profile used in some helical gear pumps. It is just so beautiful. At the same time machining these profiles seem impossible without resorting to wire-edm or similar computer driven methods. How would you go about it?
Chris, love this set of videos; great information. An observation. Could one remove the greater part of the "waste" during gear cutting and then use the gear cutter to finish up the profile? I would think that this would put less stress and wear on a valuable tool.
Hi Clickspring, you do a amzing works. can you share information about your 4 axes lathe please i tried to bought one also and how you do the off set of the gears. thank in advanced
Hi Chris another great and informative video. Having spent a lifetime around Involute gears I'm fairly familiar with them, but other than owning watches and clocks , no real experience with cycloidal. so my question is given two othewise identical gear trains, one involute, the other cycloidal is there any appreciable differance in smoothness and efficency in one verses another?
Chris, may I ask what cutting fluid you use please? (The clear fluid used on the lathe) I have been searching for something other than the usually messy (and smelly) mineral oils available. I have tried various and expensive other cutting compounds too, with variable results. Thanks in advance. I love the math and science behind developing those gear geometries.
Here I am, where my (very brief and limited) lecture about pinions, gears and transmissions states, that we only use whole numbered modules (?, *insert plural of Module here). I alsways thought thats a real thing... turns out, we were just too dumb for decimal modules :D
Prices for commercial horological cutters can be found here: ppthornton.com/shop/ typically a mechanism will require at least 3 but often 5 or more cutters to complete - Cheers :)
Excellent video series. One thing I noticed while watching this video is the nut that holds the cutter onto the arbor is "normal" right hand threaded. Do you ever have problems with it unthreading since it would naturally want to due to the direction of cut? I'm guessing the cutting forces are less than the tightening of the nut?
It is rare I come across a video that I simply cannot follow. I'd estimate 50%+ of the technical terms you use are simply beyond my understanding. It is a pleasure to be befuddled to the point of calling your work magic..
While I am just tinkering in the shed and my only trade qualification is as a butcher. Is it possible to apply gear cutting methods to sprocket cutting for use with a chain? I have converted my Harley sportster to a dirt bike. I am having trouble getting the right size commercial sprockets. It is my Australia tourer with a trailer in tow. I would like to cruise at 95kms/h and rev. at 2500rpm.
I know plenty of people who have used sprockets for dirtbikes and off-road buggies that were lasercut from flat steel. The Edge Products is a West Australian company that sells buggy kits and parts and they have a fairly wide range of sprockets for sale for 520 pitch chain, and could probably do you a custom set if you rang Tony (the proprietor) on a good day.
I have a copy of the book The Practical Mechanic from 1879 formerly owned by R.D. Tackeberry, who's handwritten notes (in QUILL PEN) are peppered through its pages. He invented quite a few things over his years and held a few patents as well, and parts of this book reveal his process almost like a diary. His notes on gearing and gear wheel circumference were brief, in pencil, but there, and fascinating nevertheless.

I'm 99.99% sure I will never make one of these cutters to make gears, but I sure am mesmerized watching Chris do it.

“Due course” = 37 years. Don’t worry though. Old Tony’s got a Time Machine so he’ll probably bring back footage for Chris soon.
I don't know what might mean to you as creator, but on my way to work, i stopped aside to watch your video! You are the best! Thanks for spreading the knowledge.
Thanks for taking the time to watch mate :)
Tony and Chris on the same day. Can't be happier.
I´m totally lost Chris... But I do know if ever will get lost, this is the place to be!
And…. I am now looking at small lathes online again. Love the videos
god i love work.... i could sit and watch it all day...

I love the vibrant green flame from the boric acid slush
From the bottom of my engineer's heart : thank you for your videos!
I love your gear cutter videos!
The brass cutter at the end would make for a killer necklace! Great job as always.
I really desperately want to be in a position where all of the amazing information you provide could be applied... I love your videos, and can't wait to see the last installment on this series!
A lot of work went into making this video. The video was thoroughly enjoyable. Thanks
Your skill is impressive when your offcuts look that good.
unfortunately in 3000 years time no one will discover this video to see how to do these processes. it makes you wonder how advanced things were in the past but due to mediums of translations how stuck we become. I hope you write your own book on solid tabs of uranium or something. Great video
Perfect timing I just watched the whole series from start to now
The king of tiny gears returns
Your macro videos are outstanding.
I like those spiky little cones.
The little cone section you cut off of the end of the pinion blank looked pretty awesome. Like something a spy would throw down when people were chasing them.
I’ve been watching you since day one, and it’s always the most peaceful and satisfying content my friend
Tools! Glorious Tools indeed. I look forward to every installation of this series.
“The fiddly things”
Love it ❤
Excellent craftsmanship as always .
Thank you for posting this excellent video!
Very detailed information on gear cutter making. Thanks Chris for sharing.
you are an artist and you love your work
Amazing quality parts, video and voice overs. Even the offcut point of the pinion gear is a work of art.
Always an absolute pleasure
Your videos are cure for my OCD.
Hi Chris I like the way you say quite presentable wheels and pinions. It sounds like something on a school report. 😂
Great video as usual buddy.
You may well be the single most satisfying (and relaxing) channel on TH-cam. Thank you, Chris!
This video is entertaining in life. It is highly entertaining in term of technology
Thank you so much!
Chris, thank you. I enjoy your attention to every last detail.
Great series. We shared this video (and part 3) on our homemade tools forum this week 😎
Brilliant. DIY engineering at its best. Thanks for sharing.
you make it lock so easy ... great video
Thank you for sharing your passion
All that work are perfect 👍👍
I'm really enjoying this in-depth stuff, Chris. Very satisfying. 🙂
Love you Chris! Keep up the great work
Caspita che lavoro!!! Grazie per le informazioni.
Also, this is a masterpiece of a video! Bravo 🎉
Excellent work,again,Chris.Thank you.
Привет, спасибо за еще одну серию. Отличное окончание дня и полезно расслабиться перед сном 🙂. Ждём продолжения.
Chris this is facinating.
that said when done large scale we use horizontal mills.
im suprised horology never miniaturized the concept.
Super professional job ⚙️
first time watching one of your vids and immediately subscribed when i saw the handwork on the profile matching the gauge. ffs dude, ya got me! i said out loud, "awwww fack" when you showed it against the gauge. keep up the great work!
Thank you for all the effort you put into these videos. Absolutely fascinating as always.
Making a tool to make a tool to be used in another tool, tooly genius.
Hi Chris. Another amazing detail video
8:26 you could shine those up and just sell them like that as pendants. I’d totally buy one.
thank god for pp thornton
I really love your video's. Excellent content, editing, the way you explain. I wished all of my teachers were like you. I would have payed more attention.
I love Clickspring.
KEEP UP THE GOOD WORK

I absolutely love this video series.
I would like to try making worm gears. However, I'm not sure about the practicality for the size I require.
Do you ever abrasive lap the teeth to match? It quickly removes all irregularities and produces matching gears with polished surfaces.
another great video with excellent content. Brilliant 👍
Satisfying!
My favorite tooth profile is the continuous-contact profile used in some helical gear pumps. It is just so beautiful. At the same time machining these profiles seem impossible without resorting to wire-edm or similar computer driven methods. How would you go about it?
Have you looked at what UnchartedX is doing pertaining ancient precision technology?
Yes I have been enjoying Ben (& co's) investigations very much, they're doing great work - Cheers :)
@@Clickspring Hope it's something you can contribute to ;)
Chris, love this set of videos; great information. An observation. Could one remove the greater part of the "waste" during gear cutting and then use the gear cutter to finish up the profile? I would think that this would put less stress and wear on a valuable tool.
Yes, a great way to extend cutter life - Cheers :)
Hi Clickspring, you do a amzing works. can you share information about your 4 axes lathe please i tried to bought one also and how you do the off set of the gears. thank in advanced
What music are you using? I like it.
1) Remove what you don’t need. 2) Heat treat what remains.
Hi Chris another great and informative video.
Having spent a lifetime around Involute gears I'm fairly familiar with them, but other than owning watches and clocks , no real experience with cycloidal.
so my question is given two othewise identical gear trains, one involute, the other cycloidal is there any appreciable differance in smoothness and efficency
in one verses another?
“The lick” @ 7:55 :)

Where and what did you study? Love your videos! Thank you for posting!

As always... Astonishing! You referenced the cost couple of times. What is the cost for those comercial gear cutters?
Prices for commercial horological cutters can be found here: ppthornton.com/shop/ typically a mechanism will require at least 3 but often 5 or more cutters to complete - Cheers :)
Epic
what about the form for internal gears?
Excellent video series. One thing I noticed while watching this video is the nut that holds the cutter onto the arbor is "normal" right hand threaded. Do you ever have problems with it unthreading since it would naturally want to due to the direction of cut? I'm guessing the cutting forces are less than the tightening of the nut?
Yes the cutting forces are quite low, I've never had a problem with it. Normal nut closing force is quite adequate for the job - Cheers :)
There's something distinctly Gorillaz like to the background music and for some strange reason it works really well.
It is rare I come across a video that I simply cannot follow. I'd estimate 50%+ of the technical terms you use are simply beyond my understanding. It is a pleasure to be befuddled to the point of calling your work magic..
We came for the Antikythera mechanism reproduction and stayed for the tools for making tools for making tools 🙃
Hi Chris. What camera/equipment/ editing software do you use. your work is amazing.
Hi. Is it oil motor ? Regards.

@ 15:15 is the saw blade a normal jewellers hacksaw type or something special?
Thanks Simon.
Just a normal jeweller's saw and blade (Super Pike) - Cheers :)

Love the videos, but at this point, I've lost track of using a negative tool to make a positive tool to make a negative tool... to make a part.
👍
Porfovor si pudieras sustitularlo en español grasias
⭐🙂👍
FUCKING LEGEND!
Why do you need to cut teeth so deep when they don't come anywhere close to touching?
So let me get this straight... If I am caught "soliciting" it's a crime, but "horology" is perfectly fine... >_
You are a machining god - but I just realised this 9:01 is porno music! 😂
With your level of knowledge you could be a Professor of Machinists.
Great video, but...
Come on Chris, you're an Aussie; it's pronounced "dar-ta" not "day-ta" 😂
