11:04 that's an engineering book cover right there

I love this channel. The workmanship, the editing, the thorough understanding of the underlying mechanisms... look forward to every upload!

I agree

I almost feel bad that I'm not going to be making any gears, because this is such a good guide series.

Videos like this are the reason I don't watch TV anymore. No commercial network would ever carry a niche series like this. Thank you Chris for making my internet screen time productive and educational!

I do love how you put the blue Dykem on the gear blank being cut. Not sure why but I find it comforting.

Do you mean Loc-Tite 609 used to glue that tiny cutter in place? That stuff come in very handy. (Dykem is great too. I use the blue, but occasionally also the green color for complicated layouts.)

@@samdude1953 No I mean the blue Dykem he puts on the outer edge of the gear blank before he cuts the gears. It’s not like he marks the tooth location and then manually cuts each tooth. It’s as if he puts the Dykem on out of habit.

​@@samdude1953 As l understand it Green Dykem is specifically meant for brass and other copper based alloys. When I was working I had Blue, Red and White. The White is meant for working with cast iron. For general work IMO Red is much better than the Blue. Blue Dykem flakes off far to easily no matter how clean the surface is. But the best layout fluid for ferrous metals is Copper Sulfate. Commonly called Blue Vitriol. Does not dissolve under cutting fluids or flake off. Yet polished off easily. Can be mixed at home using Copper Sulfate Root Killer. Dykem also used to have a Yellow and Purple iirc.

To allow him to see exactly when the cut is completed - as soon as the blue goes away, you know the cut is done. You don't want to go any further - maybe even leaving a tiny strip of blue would be best.

You are an artistic engineering genius! And your content production value is world class! Always informative, always entertaining, and always enjoyable! Thank you SO much for sharing! Cheers!

Your incredible work on such a small scale never ceases to amaze!

9th Hole, Halfway House... had to pause my round and watching Chris educate me on cutting gears 👌🏼

A tool, to make a tool, to make a tool, to make a tool, to make a tool, to make a tool. Great video.

The master teaches so that students eventually surpass the master. This is how the art expands into the future. I hope that others recognize how there are those that pass on their skills for this purpose. Cheers.

На самом деле, это какая-то фантастика. Я хочу собрать все видео автора и запечатать в капсулу времени. Если что-то случится, все эти технологии помогут цивилизации вернуться на уровень как минимум начала 20 века. Осталось продумать механизм воспроизведения.

I didn't know a darn thing about gear cutters until I saw this 😮 . Matthias's gear calculator for _"Wooden Gears"_ was a beginning guide for me to see how hand-cutting plywood gears is possible. But lathe cutting of metal wheels _(by creating your _*_own bespoke_*_ gear cutters)_ seemed very complicated; however your videos helped me to understand that it's really possible. 😊

I suggest this series has done more for encouraging clock/watchmaking than any other series I have seen. The fun side effect is that this kind of machining is not only helpful in keeping costs in-house, but a fantastic introduction to general maching too... not to mention learning attention to detail.

Always amazing. The scale at which you work is mind blowing.

Gear making has become an addiction for me. It's one of the most satisfying experiences I've ever run into in my home machine shop. Thanks for the inspiration and the quality content.

When I was working I cut more gears than I care to imagine. The most satisfying were Helicals. To cut a Helical your math for the index and Feed ratios have to be dead on at least a difference off .00005 or less. That's because we cut gears on machines that generate to tooth form. Gear Hobbing and Gear Shaping machinery. The nice thing there is one cutter will cut the whole range of teeth that would take a whole set of profile cutters.

I'm quite frankly astonished by the quality of the work you manage to produce on such basic equipment.

Another great video, Chris. Your voiceovers even have an ASMR quality for easy listening. Thanks! (BTW, I'm looking forward to the next Antikythera instalment.)

"That's so tiny!" *a few moments later* "that's so huge!"

Wow I'm impressed loctite works well enough to hold it while cutting

Damn. A whole series of videos, and calculators so you can do it at home without too much head scratching. Massive!

This channel and this guy's work is so underrated! The high level of detail and explanations turn this channel content into treasure chest full of craftsmanship delights.

It absolutely blows my mind to see things like this. The idea that if you have one lathe you could use it to build almost all the parts for another lathe is wild to me.

First tool is a tool for making the tool. Love it

Your videos are first rank! Perhaps you might consider producing a video on how you make your videos to include such things as make and model of your camera, editing software used, how you do your fantastic special effects etc.. I appreciate the effort it takes to make your videos. I would like to nominate you for a KZread award if you haven’t received one already. Please tell me how to do? Thank you!

Amazing as always Chris!!! Many thanks for sharing your hard earned knowledge so eloquently... 🙂

Outstanding series on gear cutters, thank you.

I'll never do any of this but your videos match perfectly with the mood I like for a Sunday breakfast ☕

Incredible skill, way over my head 🤯

Hey Chris I’ve really enjoyed this series, making gears has always seemed like a tough task for me, but you have kept it simple and laid a great foundation to get started. Thanks man and keep at it yourself.

Wonderful series. You've done so much work for others to get started.

Incredible skills explanations and incredible photo video.

Pin vice as collet block on grinder, going to pince that idea, brilliant.

Thanks Chris. I know it was 17 plus minutes and you had a lot of Info to convey, but I love watching metal cutting metal. So maybe not so fast on the cutting. Love that last cut on the gear. You and ToT, love you both.

You do amazing work such a talent 👏👏

Brilliant series Chris. The intricasy of the making and using the cutters to produce the gears from scratch was facinating. Cheers

OMG. This series is great, just what i was after. Thank you

Great video! I look forward to the next installment of tools, glorious tools!

Just wanted to say thank you for your time and instructions.

Technically superb, spoken and practical!

Now you have many gear cutters could the next project be a mini Michelson's Harmonic Analyzer? Great machine, Lots of gears. :D :D :D

Absolutely loved this series, It has taken some of the mystery out of it for me. Thank you. Looking forward to future episodes👍

I missed your videos. Great to see a precision expert at it again! Absolutely amazing engineering.

Can't wait for part 6: power skiving in the home shop

Wow! Really Nice!

Arguably the best channel on KZread.

The best produced content on YT. Hands down, you put together such high-quality entertaining educational content, I would think you were backed by a large production budget and company. It's a travesty that your channel doesn't get 30 million views a video. I hope you continue to be motivated to make these because I sure enjoy them. Thanks for sharing your passion with us. P.S. I have never been a machinist or work with metal in any way. (Amateur woodworker) So if you can entertain someone like me with something I have no current intention of pursuing, you are definitely doing something right with your channel. You Rock.

Another really helpful and interesting video, thanks Chris. I’ve learned so much from this series.

Great video again Speaking of edge cases, what is the smallest number of teeth for the "involute" cutters before the profile deviation to an actual involute is too high?

Amazing work,Chris.Thank you.

I love your channel, always interesting and it shows how with very little you can achieve a lot... Thank you for all your efforts in making these videos. You must enjoy making videos as much as you enjoy the hobby. Videos are exceptional quality.

Excellent series

i love this channel as a model builder, very well explained and you learn a lot

Thank you for your excellent tutorial series. I am inspired to attempt a small gear for a repair job soon.

Chris this was an absolutely marvellous revelation to me. Thank you so much! I have a number of broken toothed gear train wheels for my 22 year old Chinese 12x19" imperial lathe that has a milling head fitted to it. I have absolutely no idea as to the proper geometry to the gear teeth used. And no idea as to how to go about finding out the correct profile( module or whatever) for these gear wheels. Can you or any of your viewers/subscribers point me in the right direction please? I'd love to be able to produce at least a fly cutter type gear cutter to replace my broken change wheels. And before someone suggests it. I contacted the British seller ( Warco) and replacements are no longer avaliable and they were unable to tell me the details of the gear teeth profile.

Yeehaa for upcoming projects!

excellent work as always thanks

Sweet!! Thanks.

if i'm not mistaken you could make cutters with more cutting edges if you make more holes for indexing in the fixture, and 4 was juat the simplest pattern to make with 2 axial measurment but i am impressed how the fixture works as resharpening tool since cuting edge profile is relived inwards the profile stays the same after sharpening even multiple times while cutter itself might get smaller but for heavy weared cutter i would also implement some kind of a stop so you resharpen all surfaces to the same depth, it would avoid the situation that one cutting edge becomes longer after sharpening and the cutter hunts with just one edge while rest remain fresh and hidden because they have nothing to do, with multitooth cutters that might be intentional to stagger the cut over multiple teeth like a broach, but with only 4 edges it would be probably best if they all cut the same

And subtitle of this episode should be: "When a scratch from polishing is comparable in size to your cutting tool" 🥰

Fantastic work :D

This is viewing perfection. I appreciate the effort involved, thank you. Is there any chance of a blooper reel just to show you're mortal?

Thank you for this series, it has been awesome! Have you come across any resources that discuss how to make cutters for internally toothed ring gears on a shaper?

Alright, so check it out: You use tools, to make a tool, to make a tool, to make a tool, to make a gear. I'm just trying to be funny, but it is truly good craftsmanship because now you can make many gears all exactly the same.

Toppingly. As always.

Very interesting.

Thanks. I will do this when I get a late.

I'm going to offer up an idea for getting lathe toolng made to make your own form cutters. Not necessarily cheap but it could produce very accurately shaped lathe tooling with the side cutting relief built in. Wire EDM.

Another great video as always. Can you please tell me where you get your tool steel from in Australia? Cheers.

Hi, do you sell drawings of your tool systems or have you written a book about all the clock making tools in your videos. many thanks Jim (UK)

Am I the only one imagining an Antikythera pocket watch?

I struggle with the speed the newly made cutters are run at. Surely material cutting surface speed applies.

Can you show the escapement cutter creation and use? It sounds like a beautiful short video (or short)

yay

Alloy toothed pulleys for belt drives?

Does relief angle matter? Like im sure theres a minimum for chip clearance and then a maximum to keep structural integrity; but is there a prescribed angle for types of cuts?

1.5 Module. Approximately 17 Diametral Pitch. Total toothedepth about .125". Not really that large. It is not just lnvolute or Cycodial gear cutters that can be made withthis method. Angle cutters, spline cutter (involute and parallel types), cutters for toothed belt sprokets etc.

A bit of a random comment, here: I've noticed that power and lighting switches in the States are 'up' for 'on'; here in the UK it's always been the opposite - down is on, up is off. What's the norm in Australia, Chris? (Making allowances for being upside-down, of course...🙃)

Cutting a worm gear would be done in the same way you would do single-point thread cutting. The cutter profile would be the same as for cutting a rack, except maybe with extra clearance.
