Tools, Glorious Tools! #10 (Part 1) - Shop Made Gear Cutters - The Sharpening Tool
🕑 Added 2020-04-30 03:39:29 +0000 UTCHi Folks,
What started out as a minor excursion prior to working on Patron Series 3 has evolved into a little mini-series on shop made gear cutters - do please enjoy Part 1! (Sharpener drawings to follow shortly) [EDIT - Drawings now available below, at the bottom of the text]
Cheers,
Chris.
Other updates: Work continues on the new platform - We are hoping to have something ready for the first set of Mentors to beta test inside 10 days and I will keep you posted on how we go. In the meantime, keep accumulating those project shots, CAD files, drawings, videos etc so that you can hit the ground running with it once it goes live.
No news on the paper - we're still in review, so nothing much to report other than that I will let you know as soon as anything changes.
Discord - The Sunday Discord chats have been terrific fun and are now a regular event - If you've not yet dropped in, do try to come along this Sunday at 22:00 GMT. Lots of sharing of weekly pics, knowledge, and project updates from around the globe. (How to connect to the Clickspring Discord: support.patreon.com/hc/en-us/articles/212052266-How-do-I-receive-my-Discord-role- )
Lastly, the survey data has been excellent in guiding the direction of the new platform - if you've not yet filled it out, it will only take a minute or two and can be found here: http://unf.co1.qualtrics.com/jfe/form/SV_9sHv2VtB0I3DMxL

So I have a question/idea about the buttons. Could one perhaps mill a small flat on the back of the button head before cutting the 15 degree face, thus allowing the use of a precision square to take the guesswork out of rotating the buttons to 45 degrees in the tool body?
Clickspring
G'day Rod, its an excel spreadsheet so you will need excel or the free excel viewer - Cheers :)
Rod Cole
In trying to open the Cutter Calculator I get told there is no App available in my country. What am I doing wrong, I'm not real handy with computers~
David Paterson
great reference site, thanks even if most of it is difficult to source is Aus
Clickspring
Thanks Daniel, good info - I have edited my answer above to better reflect the point that I wanted to make: that we're talking about conducting the process in the home shop with common tools and simple heat treating - Cheers :)
Daniel J Bostrom
High speed steel can bee annealed, and then machined similar to tool steel (machinability though is not as good) then heat treated to harden. However, the temperatures and times at heat as well as techniques are different. Good technical data at http://www.crucible.com/eselector/prodbyapp/highspeed/rexm42.html for the M42 HHS. Data for many other steels, both HHS and carbon steels are also available.
Clickspring
Many thanks mate, it looks like a sweet little tool, thank you :)
Jeff Armstrong
I've found the article and have put it up on the Discord channel.
Clickspring
Hello mate - There are quite a few high carbon tool steels to choose from, although O1 tends to be a fairly good all round performer. Not to be confused with HSS though. High carbon tool steels possess the key attribute of being able to be easily formed into delicate, complex shapes in the annealed state using common machine tools, and then hardened with a simple oil quench. However working and heat treating HSS usually falls outside the scope of the home shop. If the requirement is a profile that can be formed straight off the grinding wheel, then HSS is terrific. However if its something more complex (and the shop has the common forming tools like a lathe and mill) then carbon steels are an easy solution - Cheers :) [EDIT - edited to clarify the point that we're aiming for processes that are easy to implement in the home shop]
Ryan Johnson
I am so excited for this new series on making your own gear cutters. You said in the video that you are using O1 tool steel to make the cutters and you also mentioned that the steel choice makes for lower quality and lighter duty cutters. My question is if using a different type of tool steel would result in a higher quality cutter or if you already chose the best steel for the job. Also, I found 6x25mm and 10x40mm hss bars 200mm long on ebay for under 20 US dollars , I don't know if those are large enough to make the cutter out of, but it would be cool if you could cheaply make your own hss gear cutters.
Clickspring
Hello mate - In principle, yes - although the main challenge of forming a profile cutter is getting that profile to be exactly what you need it to be. The beauty of a tool steel based process is that you can work the steel in the annealed state very easily (as you will see in the next video), and then transform it into the martensitic state with a very straight forward heat treating processes - Cheers :)
John Gentzel
Nice design and great video. This might be a silly question (I haven't used a lathe or mill since High School) Could you make gear cutters using carbide inserts or are the forces involved too much for something as brittle as carbides???
Clickspring
Great to be back Chuck, Cheers :)
Clickspring
Thank you mate, you too :)
Chuck Kirchner
Well, there you are. I thought maybe Tony stabbed his voodoo doll in the wrong place and you had perished. Glad to see you back!!
Clickspring
Cheers Gary, you too :)
Clickspring
Thank you mate!

Hi Alisa, I use Loctite 603 retaining compound - specs here: https://tdsna.henkel.com/americas/na/adhesives/hnauttds.nsf/web/4A89537CE4638581882571870000D851/$File/603-EN.pdf - Cheers :)
Clickspring
Ha ha! Awesome mate :)
Clickspring
Cheers mate :)
Brad Thayer
Yay, a new video with new content from Chris! Glad to see you haven’t gotten rusty. And it’s too bad the review process is anonymous. I suspect there are a few thousand angry Clickspring viewers that would happily storm their residences to get this thing published! Stay safe, though your PM seems to be doing a bang up job and making the right calls.
Gary Knight
Great Video Chris. Always learn something. Keep safe.
Mark Hobster
Great vid thanks a lot for making this and I look forward to seeing future video's in the series, Nice gratuitous bling aswel 😁
Alisa Amiella
What threadlok do you use?
Jeff Armstrong
It's in a hard copy that I need to scan anyway so it could take a while to find. I'll put it up over on Discord when I find it - don't hold your breath though!
Duncan Luddite
Wow! Will be watching this again soon; was mesmerized by the visuals, and not paying as much attention to what you were saying first time through :D I'm also very tired, so that's my other excuse. Gear/Wheel making is one of my top of the list 'want to' skills (as it *is* the foundation of watchmaking and automatons) , along with making a set of very fine needle files........never knew I wanted to make those before your video on case hardening and file making :)
John S Dilsaver
This is so spectacular and such a pleasure to watch! Your videos and the Sunday chats are always so encouraging to the rest of us, at whatever level of skill we happen to have. Thanks again!
Clickspring
And may a thousand gear projects bloom :)
Clickspring
Ha ha! Cheers mate :)
Clickspring
Me too :)
Paul Busby
As always a great video. Really looking forward to the rest of this series. Anything that makes gear cutting more accessible is fantastic. The excuses to not do this are getting shorter and shorter

THE GLORIOUS RETURN OF CLICKSPRING!
Peter Kransz
I still just see pikachu
Clickspring
Ah very good! Have added them to the gear links above :)
Andy Pugh
Also: Not i the spirit of your working methods, and blatant self-publicising, but my own YouTube video on gear hobbing (ie with a spiral gear hob) with a mini-mill has proved surprisingly popular https://youtu.be/ZhICrb0Tbn4 Though since that I have improved both my video production and my machinery: https://youtu.be/xdE46yvckbM
Clickspring
Ha ha! Very good :)
Iain Deas
Well the tables have turned, my dad is always over asking me to make / fix bits and bobs for him. Now I get to yell when he doesn’t put things away 😆
Clickspring
Hello mate - No kids, but I would have loved that too!
Clickspring
That would be good to see - please do Jeff :)
Iain Deas
No sooner had I started rewatching the clock build and then this little gem 😊 I remember in an old video you mentioned being away with the family, do your kids have any interest in your machine shop? I’d have loved this as a kid!
Jeff Armstrong
So now we know what the strangely shaped piece of aluminium is for. A problem I have is sharpening the smaller drills (less than 1mm) but there is a good jig for that. I'll see if I can look out the drawing I have for one that holds small drills (down to about No 50) at the correct angles to sharpen these.
