I cannot even imagine a machinist's school that would teach this more properly for tuition than what we have here for the price of watching a couple of ads.

[@bertradmacher2623]

It's a lifetime of tool and dye architecture 😮

[@-_._._-]

​​@@bertradmacher2623 need a tap and dye and some dubya dee forty

[@bablela26]

Machinist school doesn't teach about hobby tool making. It teach you to use these tools because they are common tool. Exemple I saw available on market look like the multiple tooth gear cutter, bit it has more tooth, and also they are stacked on top of an other (looking like corn lmao). Everything is about producing part fast and using the full potential of machines costing in the 6 digits. Now then it is possible to learn the skills and to apply them to hobby machining, but sadly in school many things are forgotten in the progress of technology. I've gone to mechanical engineering and learnt to do technical drawing on paper, something that seem rare nowadays, so you know what I mean when we loose many skills

@@stuartbutler7452 I'm questioning myself right now whether or not that is irony.

[@warrenjones744]

Chris, Your close up cinematography is first rate. I love it when I see the tool marks and they are sharp and infects. Brilliant man!

[@EleanorPeterson]

A thief breaking into a shed or workshop is usually only interested in stealing portable power tools - drills, routers, spare battery packs - little realising that the true value lies in tools like this. Lovely work, Chris.

[@mpetersen6]

I knew one gentleman that had his lathe stolen out of garage.

[@InsideOfMyOwnMind]

​@@mpetersen6I knew someone who built up an entire machine shop from government surplus auctions and had to give it all back for two years because the items were never properly written off before going to auction.

[@derschwartzadder]

The value (for the theif) is in the genetic fencing price. Not something single purpose and recognisable.

[@Chromevulcan]

I love your videos, but I'm always impressed by the sharpness of your cutting tools.

[@Sawta]

It's always so fun watching your videos, Chris! You have a certain kind of positivity and interest that is always pleasant to hear. Your work is really good, and I hope that you continue to enjoy what it is that you do. 😁

[@ChocFlip201]

This is one of the highest quality “how-to” videos ever created. Thank you @clickspring from the bottoms of our hearts.

[@patw999]

I second everyone else, I went to machine shop classes in the 80’s and they didn’t cover this like you did. Thank you Chris. Even if I never cut a gear all knowledge is good.

[@mcorrade]

Chris these are my absolute favorite of all your types of video's. Tools tools glorious tools ya baby

[@stabilini]

This is insane quality... and those graphs over still images are wonderful... thanks!

[@RCake]

This easily was one of the most beautiful and best filmed videos I have seen on YT, ever. Eye-wateringly beautiful in fact. Thank you!!

[@user-xw7jt2ol9t]

In my opinion you are a talented mechanic. Thank you for sharing your videos with me and everyone, it's very useful

[@opticalmechanic]

Stunning craftsmanship. I’ve worked in precision engineering for 30 years and you don’t see this attention to detail often, if at all; and it’s all in a home workshop.

[@106640guy]

Your thumbnail test gives me shivers all through my body

[@heyheyjc]

Makes me rub my nail for hours after, can't bear it

[@lumotroph]

Gorgeous music and cinematography ❤

[@dbayboyds409]

It is astonishing to me what you’re able to create in your workshop. The knowledge and patience to do it in the first place coupled with incredible filming and natural teaching style is a joy to watch. I’m unlikely to ever need to make a gear like that and I’m now 30min late to work and I still consider it time well spent. Thank you for showing what is possible through application and dedication. Absolutely love your channel!

[@jodyvanliew2514]

Great work as always . It is so pleasurable to watch such a great craftsman work .

[@iskandertime747]

That sharpening jig is so cool!

[@PAINFOOL13]

Knowledge, Skill and Patience 👍🏻 Just awesome Chris. Thank you Sir 😊

[@chloehennessey6813]

Dad says he has a man in his machine shop he hired 12 years ago that makes cutters for him; he can look at the metal, look at the order sheet and eyeball the parts into cutters on the machines. It’s actually freaking amazing.

[@Hoaxer51]

Is his name Tony? Lol

[@rockytrh]

Fascinating as always, Chris! You are not only a master of your craft, but also an excellent teacher.

[@rollonsummertime]

I've been a machinist since the early 70's and have seen a done a lot of things, but your skill, knowledge and craftmanship never fails to impress me,,thank you sir👍👍👍👍

[@kepamurray1845]

The fly cutter section was a nice little addendum. 😂

[@thefunbot]

been a fan for many years - love your videos and learning all the processes needed for each machining job. i feel smarter for just watching them.

[@MarkKent2112]

ngl -- Your videos, background tunes, voice, and machining perfection are ASMR to me.

[@mikekelly1771]

That zero backlash on the rack and gear is just beautiful. As always, a master class.

[@untrust2033]

Incredible the amount of work that goes into making something like this!

[@phuzzygreene]

You are the public face of math, meets art, meets science, meets teaching. Thank you for sharing.

[@stephenbridges2791]

That is some seriously fine machine work.

[@SauronsEye]

What would be cool to see would be the use of a strobe light to stop, slow down to cutter head.

[@VolodiaLukianov]

Привет, Крис. Ваши видео имеют практически терапевтический характер. Это невероятно. Благодарю вас.

[@_D_P_]

30:40 This is the payoff shot was was waiting for the whole video. Seeing 2 finished gears spin together, especially with the mixed color metals was so satisfying.

[@Noise-Bomb]

This is an invaluable resource and will definitely come damn usefull at some Point. Thank you for this series.

[@cockedhat1]

Hello Chris, morning from mere mortal land. A great video, you must stay awake half the night thinking up operation sequences! Looking forward to the next one.

[@karlohorcicka7388]

That thumbnail test... I could never

[@frfrpr]

This is some seriously good filming and subject manner. I have yet to hear a voice over that's better. Combine that with the different tracks of music and shop sound. Impressive.

[@WolfTronix]

So glad you showed the gears meshing.

[@DasIllu]

As someone experiencing summer in the northern hemisphere we need more instructions on "Flycutters" 😀I am as always in awe of your skills. Seeing you work somewhat demystifies how we got our achievements done. I am a mere electrician, not much space for creativity there... for a damn good reason i might ad 😀 I however had the opportunity to work with some lathes, mills and grinders. We were trained to aim for the 1/500mm.

[@afnDavid]

Yay! Cool !! You do need that maths (triangles) you were taught when you were 12 yrs old. I hope you learned it.

[@bayudharmakusuma3142]

Smooth as always

[@texasman1836]

I think it's awesome how you can make one tool have multiple functions, like the arbor in this video and your sharpening tool in a previous one...which (spoiler alert) seems to be designed to sharpen this involute cutter as well.

[@anothernate3302]

For oxidation protection during heat treatment, my father used stainless foil packets with a bit of paper inside to consume oxygen

[@crabmansteve6844]

That's what I'm used to doing too. But it doesn't always work as good as Id like in my experience, I'll have to try this next time.

[@milesdavis1620]

Foil pack with a drop of oil inside is my experience.

[@mcgam2000]

All I can say is "WOW"!!! Now all those ancient magazine articles I have downloaded discussing making gear cutters make sense. And now I see that for cutting very small gears with fine teeth, this method is necessary... Thanks again

[@fabi922]

Even though i´m basicly a toolmaker, i´ve lerned a lot in your videos how to create divices and tools. Thanks for your nice videos :)

[@Danger_mouse]

Chris, as always another display of the the complete package here in this video. The mastery of your various crafts, toolmaking, videography and your ability to communicate it all clearly for others to follow and enjoy! Second to none mate 👍

[@wobblysauce]

Elegant… that is a nice way to do it and the calculator, used to be only in a few books many inches thick.

you're channel has that 'How It's Made' vibe to it.

[@magicbytes3835]

1st Class work Chris, truly amazing skills you have, thanks for sharing, I really enjoyed watching and learning, cheers from me. 😷👍👍👍

[@paradiselost9946]

a form tool is shaped for cutting a form. such as an involute. threads. etc. a formed tool is back relieved in a way so when sharpened, no special consideration is required to keep the form correct. when form tools are relieved to a straight clearance angle, the shape changes as you grind back for sharpening and setting up is tricky... like putting back rake on a threading tool, you change the profile of the thread.

[@mixiekins]

Same as the others, but what I'd like to add is that I really enjoy the music selection in this one. It's easy on the ears and unobtrusive, and I kinda actually want to find the(se) artist(s) and binge more of their tracks.

[@TheTarrMan]

Fascinating! Thank you for doing this for us.

[@CameronMcCreary]

Years ago when I machined barrels for John Martz the Luger carbine maker from Lincoln, CA , they had to have a relief tool made similar to the gear cutters here. I took a keyseat cutter of the correct width and placed it in a collet in my endmill grinding machine and used a thin silicon carbide green grinding wheel and/or Aluminum Oxide and radiused the correct form and ground one side then the other. Because I used a keyseat cutter to begin with the correct cutting geometry was already there I just cut the form and I did one cutter in M2 tool steel and Carbide. All that was left was to set my barrel in a jig that presented the top rear of the chamber to the cutter and I found center and began cutting. Working on parts for John Martz and his Luger carbines I made alot of form tools from Woodruff keyseat cutters mainly because they had cutting teeth from six (6) teeth to twenty four (24) teeth and the finish they gave to the formed design of the part for the Luger carbine was very clean, smooth and without chatter. Everything wound up in a compartment in a cabinet with a description on the box with the jig, special cutter and picture of the part made by the tools. It was complicated somewhat but not nearly as much as the method used by Clickspring. I also didn't have any hardening of the cutter to do.

[@Gpcas9]

17:28 This is a happy cutter. Shown by the smiley face near the center hole ;-)
