Tools, Glorious Tools! #10 (Part 3) - Shop Made Gear Cutters - Making "Involute" Gear Cutters

[@InsideOfMyOwnMind]

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.

[@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

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!

[@mcorrade]

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

[@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.

​@@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.

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.

[@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!!

[@renu1793]

Infinitas gracias por poder ver tu trabajo son fantásticosssssss cada día aprendo un poco más repito mil gracias por compartir

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

[@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👍👍👍👍

[@jodyvanliew2514]

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

[@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!

[@_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.

[@logant8619]

I've been watching your content for years. Outstanding work!

[@Clickspring]

Thank you mate, terrific to have watching :)

[@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.

[@untrust2033]

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

[@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.

[@PAINFOOL13]

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

[@rockytrh]

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

[@MarkKent2112]

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

[@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

[@stephenbridges2791]

That is some seriously fine machine work.

[@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.

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.

[@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.

[@angelramos-2005]

Great video,Chis.Thank you.

[@CatNolara]

Really love this video series. Now I'd be interested in how well the teeth mesh with eachother. Or having a pair of these gears shown running together under power would be the ultimate proof of functionality. Hope we get that in the next video.

[@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.

[@FoxMacLeod2501]

I love this series, Chris! An additional tip for my fellow viewers: it's important to make sure your sharpening stones stay flat as they wear. Get yourself a flattening stone when you buy your first (or next) sharpening stone, & use it before every sharpening session. This can help steer clear of some pernicious angle and finish problems.

[@VolodiaLukianov]

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

[@TheDistur]

This is such a beautiful process. I was just watching a guy make a Eureka mechanism for making gear cutters also.

[@jeanpierrebonno4703]

[@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.

[@FieryWACO]

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.

[@kisoia]

[@MASI_forging]

Incredible work. 👍👍

[@piconano]

Love love love your videos.

[@stihl888]

Love your work mate, one thing I've learnt when sharpening using stones is to routinely resurface the stone face using a diamond plate as the stone tends to hollow out quickly from routine sharpening meaning the edge is not true. A few swipes with a grey led pencil then honed on the diamond plate will show when the stone becomes true.

[@samuelwildbore349]

Chris you have an incredible mind and hands of the same calibre. These videos have been really great for me to learn how certain geometries can be made using machining, Im loving the series, got a question for you regarding making the fly cutter, does the distance of the cutter from the centre point (effective cutting diameter)have any effect on the cut? The only thing i can think of is a change in relief angle? Thanks again

[@snork_games]

I see the little engraved smiley face you snuck in there @17:28 :)

[@craigwink]

Thanks, Chris, for another hypnotizing video. I'm hoping these tools are going to be used to create the Antikythera Mechanism gear train that locates rifts in spacetime and allows you to visit its maker, Archimedes.

[@cest7343]

Don't be fooled gent's! he's not the casual machinist, he's a damn clocksmith! 🍻 And then some! (Chris, this is beyond finest craftsmanship)

[@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.

[@dougmorgan6616]

The mirror like finish on the gear teeth is impressive.

[@donmittlestaedt1117]

As always, EXCELLENT!

[@kepamurray1845]

The fly cutter section was a nice little addendum. 😂

[@SauronsEye]

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

[@aticuss]

OMG this is absolutely great

[@seanb250]

I don't think you make errors, I think your possibly not human!!! incredible workmanship and exceptionally articulate in the way you work through the process. If a multitooth cutter created the way you have done and used appropriately as you described, how many cuts (of lets say 5mm in length) in steel would you expect roughly before the edges would need resharpening? How much material can you take off the cutter for resharpening before the cutter needs to be replaced? Cheers
