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!

[@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.

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. 😁

[@stabilini]

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

[@ChocFlip201]

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👍👍👍👍

[@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.

[@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

[@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!

[@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

[@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.

[@PAINFOOL13]

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

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.

[@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

[@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.

[@rockytrh]

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

[@iskandertime747]

That sharpening jig is so cool!

[@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.

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.

[@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.

[@ls2005019227]

Excellent video & information. This (longer) format is much preferred- Thanks!

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.

[@TheDistur]

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

[@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.

[@bayudharmakusuma3142]

Smooth as always

[@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.

[@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.

[@10223220]

Once again what a great video I like to watch and learn 👍

[@SauronsEye]

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

[@joesmith4494]

Good afternoon to you good sir. Much thanks

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.

[@peternicholsonu6090]

Simple question from a simple mind...mine. Absolutely love your videos since Antikythera. I can only work crudely with wood so highly value my tools....and you make tools! My question is “how does an oil stone remain true”?

[@PeregrineBF]

This arbor could be helpful in making gear hobs as well. Most home shops don't do gear hobbing, but it is quite a bit faster than single-tooth cutting. DIY hobbing attachments are possible, e.g. Andy's Machines shows how he made one (and makes his own hobs).

[@mpetersen6]

One handy inspection trick for checking any home cut gears. Machinery's Handbook has a method for checking backlash in gear teeth based on the measured distance over a set number of teeth with a vernier, dial or digital caliper. The basic charts give the value for 1DP. 14.5° and 20°. For different pitches devide by the DP. For Module convert Module to DP devide pi by circular tooth thickness in inch dimension. For 1 Module 3.1415 ÷ (3.1415 ÷ 25.4). 3.1415 ÷ .118 = 26.62 DP Section starts on page 972 of my 19th Edition. This distance is measured over 2 to 9 teeth depending on the tooth count of the gear.

[@jeanpierrebonno4703]

Very nice work, and thank you for all datas, particulary for calculator

[@Clickspring]

You're welcome :)

[@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

Hey Chris, exceptional work in every aspect as per usual. Thank you for the inspiration to get better and better at the stuff that I do. As a Sydney-sider I have been meaning to ask you for some time now as to where you get your material supplies like steel and brass etc that you use in your projects when I spotted the label from the Hales company. Are there others that you would recommend for price and quality here in Oz as I am early in my metalworking journey spending most of my life working with beautiful timbers and using metal in very limited quantities for accenting etc but am looking to expand my skills having bought a small lathe and mill a few years ago but mainly unused as my wife developed leukaemia a few weeks after I finished placing and roughly setting up the tools and thus our world of necessity stopped. Now, just over three years since her death, I find myself starting over again in lots of areas including this. So I thought that I’d ask, as well as to simply thank you for being such a fine instructor and such a deeply skilled craftsman in so many areas and for being such a gentle influence and inspiration for a bloke who at 62 and forced to retire early due to health issues and who is very grateful for what you do. Take care Chris, see ya and if you’re ever in Oatley, we’ve got a great little local pub here, best staff and quality and food in Sydney I reckon, well, apart from the RSL here which has great food and staff of equal quality as well, first rounds are on me mate . . . 😎👍

[@Clickspring]

Hello Phil, great to hear from you - I get silver steel (aka 'drill rod') from Blackwoods, Hales for the gage plate, mild steel plate etc and many other 'small order' materials from ejwinter.com.au/ I also pick up the odd interesting bits and pieces from local machine shops, and for casting hit up the scrap places for copper, aluminium etc - Cheers mate :)
