Making gear cutters in the home workshop using Eureka tool
HTML-код
- Опубликовано: 13 май 2023
- In this video, I make a Eureka form relieving tool based on the design in Ivan Law's book Gears and Gear Cutting. Having made the tool, I use it to make a set of Module 0.6 gear cutters.
The steps in the video are: make the Eureka tool itself; make the button tools that are used to profile the cutters; make the set of gear cutters.
In the video, I make the mandrel and indexing sleeve for the tool. I had already made the other components.
I made number 2 to number 7 cutters. A number 1 cutter is needed to make gears with 135 or more teeth, which is a size I don't expect to need. A number 1 cutter also requires a button tool with very large diameter buttons, which can be impractical without cutting away portions of the buttons to avoid clashes with the Eureka tool.

Folks, this is the first time I've seen a video about making the truly wonderful 'Eureka'. As far as I know it's the only video about it. The tool solves a very, very tricky problem, that of automating the manufacture of the complex tooth shapes required on an an involute gear cutter. It can make cutters for any size of gear with any number of teeth within its size range - either diametrical or modular pitch. It really is a wonderful invention and I strongly recommend anyone interested in gears to have read of the book mentioned in this video. You will learn a lot! Liked and sub'd.
Hey, here is another person that made one of these gear cutters if you're interested.

I have schematics of this mechanism in a gear cutting Machinist book but first time seeing one work.
Попробуй чпу. Там любые кривые можно делать. За 30 минут максимум.
No robertt4522 made a video with eureka tool a while ago: ruclips.net/video/F_w92CEMlT4/видео.html
Exactly what RUclips is for. Sharing invaluable knowledge
Very impressive and to see it made with machines that are realistically affordable for a home workshop similar to my own 👍
I read that Ivan Law book last year, that eureka tool was quite the holy grail for home making gear cutters.
Finally, someone makes this fabulous tool on RUclips!
My favorite book in the series.
You earned my subscription as my way of saying thanks.
Thank you!
Very impressive work , I’d never seen anything like that done in the home shop before.
I first saw this device about 10 years ago and fell in love with it. At the time I had plans to build some things requiring gears but life changed and I never built the tool or the project. This is an excellent addition to Ivan's book and will serve to guide those who will build this tool!! Excellent. Thanks.
Very well done. Great attention to detail and very clear video production. Thank you!!
Thanks!
Amazing , its great to see videos like this , si that old techniques of making things dont get lost in the past.
Fantastic video! I'd never really considered the process that would be needed to provide relief to the sides of the teeth, really ingenious.
I always wondered how the relief was made. Nicely done. I learned something new. 👍
I have no words to express. I'm speechless. Marvelous creativity and marvelous engineering. 👌🏼👌🏼
Mighty impressive, enjoyed it a lot 🙏
Thank you, not quite up to your standard yet though unfortunately!
@@MetalMachineShop I think its very, well made 🙂And the first long comprehensive description of how it works and is used on youtube - thanks a lot for that!
Nice presentation. I made the Eureka tool about 15 years ago and I've since forgotten many of the steps it took to get the parts made. Keep up the excellent videos!
Always amazing to see how many smart tools there are available
my mind has never been more spectacularly blown. Firstly i never knew the Eureka tool existed and now that i do i will never be the same
Haha I enjoyed your comment!
Loved this video. A lot of content in one video. I most definitely liked and subscribed 👍🙂 Thank you taking the all the extra time to film and edit everything. I know it’ adds quite a bit of extra work, but I appreciate it.
Thanks, I’m glad you found it of interest, makes it all worthwhile.
I made this tool two or three years ago. Never got to try it out because the price of tool steel(water cooled) was a ridiculous price in my neck of the woods. Thank You for the time you invested in this video.🙂🙂🙂
Same here - once I realised silver steel plate was involved it was a hard no. That stuff is stupid expensive in Australia. I was fortunate enough to be given some for my loco expansion links because otherwise they'd be mild steel.
I have the drawings for one of these in my books, nice to see one made and in operation, well done.
Fabrication is an art form, Well done Sir 👍
Great video technique and content. This is the only video I've found showing this unusual tool. Fascinating to watch, makes the text in the No17 handbook come alive.
That was an excellent video you have my subscription
Thanks!
That was a very complex process. Worthwhile knowing about and interesting to watch. And it it convinced me to keep buying cutters. Great video. Gilles
I agree, buying cutters saves time!
absolutely stunning what you have done,, i don't think i would have got past the first step!
That's fabulous. Well done!
You've earned yourself a sub, that was very interesting! A lot of work goes into making those gear cutters, and I now know why they are so expensive! 😬
As hobby machinist I am amazed with your knowledge and craftsmanship, well done Mister
Thanks!
Wonderful! A wonderful homemade! Thank you for sharing!
wonderful solution, this will make gear cutting economically possible
No need for CNC and people don't realize it.
Fantastic demonstration.
Super-interesting book and beautiful work. The author notes that the mystery will unfold when the reader views the finished product, and he was correct. Now I understand. Not likely I'll ever build one, but you're reminding me that I need to get back to work on my Harold Hall Advanced Grinding Rest.
I made a HH grinding rest too! Very useful tool.
I just stumbled across your channel, and hot damn that's some fantastic work. And I thought I was already subscribed to all the good machining channels on RUclips.
Thanks!
A lot of work but very interesting and well worth giving it a go. Thanks for posting this.
Great work! Ever since I needed a 22/29 DP with a 20 degree PA gear for my Hardinge HLV-H, gears have really interested me. Cutters for Fellows Stub are very difficult to find. You have given me hope to eventually cut my own gears for my lathe. Cheers from Florida’s Space Coast!
Good luck, you can make simpler cutters using the button tools but without needing the Eureka tool. The Clickspring channel has some good vids on the subject.
Это поразительно! Сколько труда человек вложил! А у нас немеряно таких фрез ушло в металлолом, как же это больно... Да и не только фрез...
I’ve rescued some good stuff from machine shop scrap bins before!
That is seriously magnificent work and that eureka tool really is quite something.
Colour me impressed
Thanks, glad you liked it!
Very fine work. Respect!
Thanks!
Гарна робота !!!!Респект!!!!!!
Brilliant presentation.
Very clear and informative.
The home made cutter grinder, very simple.
Thanks!
Brilliant video, very enjoyable ! thank you.
I have that book somewhere, I will have to did it out, many thanks👍
Great job on this tool. We shared this video on our homemade tools forum this week 😎
At 1:33 he sets the cylinder down on the glass and it continues to rotate. Really satisfying.
That was very cool to see, thanks for taking the time to document your build and sharing.
I'd love to make one myself one day, along with a banjo for a mill table so I can make helical gears.
Nice work. I'm just getting into gear cutting. This would be a great project. Thanks for sharing,.
Really awesome. Thanks for sharing.
Years ago, I built a hydraulic relieving attachment. It had a large cam with 8 lobes that drove a piston placed beneath it like a steady rest clamp. The cam was mounted on the same mandrel as tool blank, between centers.
The piston was plumbed to a slave cylinder with a reciprocating piston in the toolpost. This slave piston had the tool bit sticking out.
This worked. The problem is vibration and chatter marks on the work as the tool enters. So i did the relieving before I cut the gashes, this way I could pick the best position to make the gash.
I did all this because I couldn't find a special stub tooth gear cutter. Otherwise it's difficult to justify the time spent doing this.
Sounds like an interesting challenge at least! Could probably use the same set up as a follower for profile turning.
Brilliant work. You're a true artist with great knowledge.
I’m happy you liked it!
Amazing to see how it's done
Thanks for the video for learning purposes. Your very talented.
Thanks!
Amazing job wich dimands knowlege and smartness , skils, and ,,straight ,, hands . And at the same time he has finger of a piano player... A big respect and regardes from Armenia..... He is talent!
You wouldn’t want to hear my piano playing!
😂😂 I guess.. i told it in good sense. Because in territory of past soviet union a man who works industrial specialties suppose to have hans of godzilla. Dirty ,hardened skin with cracks barbs that can injure a human..
@@krokodilchik haha I should get my hands dirtier!
Very Nicely done! Eureka!
Awesome video, answered questions I didn't even know I had!
Brilliantly done sir
это уникальное видео. такое полезное не каждый день встретишь
Thank you!
Very Nice!, Good detail an explanation. Obviously you know a lot about machining.
Well done, very impressive.
Eres un artista. Mis respetos!
Saludos y larga vida!
That was excellent. Well done.👍⭐
Thanks 😊
Very informative,- thanks, must be tried. 👍
Great work! I enjoyed that.
Fantastic!! Great video!!
Nice job. I had read about the Eureka tool in old back issues of the Model Engineer magazine but I'd never been able to see it in operation. It almost seems to be too good to be true.
I met Ivan a few times, nice chap.
Great stuff I have never done anything like that!
Absolutely brilliant, thoroughly enjoyed this, subbed 😀
I made many of the parts for one of those but sold what I needed it to make gears for and never finished it. It was a fascinating device.
Thank you for the fine work on the video and the part! I've purchased a few cutters but this seems like an intriguing problem and perhaps a cost savings too.
Cost saving at the expense of a lot of time though!
Bro that is so amazing.
Look fabulous as always 🙂🙂
Muito bom aprendi bastante com seu video, Att. Vicente
excellent work! thanks for sharing.. subscribed
Beautiful work! I have always wondered how I might make the occasional gear with out spending a large pile of money. I will have to find the book. tyvm
You can make simpler fly cutters using the button tools without having to gi to the triuble of making the Eureka tool. It's all in the book.
Most excellent.
So we'll explained! Thanks very much.
A new subscriber here 😁
Thank you!
That motivated me. Thanks
What an excellent video thank you. I've heard of a Eureka tool but never seen one in detail and in action. All out of my ability so purchased a set of M0.6 cutters, I know its cheating but aliexpress is very tempting these days and to be honest I'm very happy if I can just cut a gear let alone make the cutters. I have subscribed :)
I must admit, I did regret not just buying the cutters!
That’s very cool.
Neat … I made my eureka tool a couple years ago and posted a video here to which had some views… but have yet to make blanks and button tool… some day… it’s a good project/tool to make and have in your arsenal…
Well done 👍👍
Very interesting video 🙏
Very impressive.
Thanks!
wow... this is awesome tip thx
Amazing !
Just found your channel. Subscribed!
Excellent, thank you!
very cool, not sure I can do all that with just the lathe though...atleast not at this point, maybe with more experiece and some wierd tool builds under my belt.... those books look fascinating too
thanks for sharing
Very interesting, read articles about the Eureka tool, with mixed results of building and using it.
Nice video shot, keep it up,thanks :)
Thanks, more to follow soon!
Remarkable!
This is insane!!!!
High precision and fast speed
Really interesting solution to producing the relief on each tooth. Though, I'm a bit confused as to how the round buttons produce the volute geometry. The tooth profile is far more complex than just two radii.
The round tool profile is not an exact involute, but it is close enough for practical purpose and for small gears you will not notice a difference.
Just wow 😮
After reading the book some years back I have been threatening to get to grip.
Thanks so much for a ton of help.

Best video ever 🎉🎉🎉
Except for yours!
Very informative, nothing extra.
Awesome
Very interesting video. For the equipment you have, you do pretty high-class work! Do you sharpen the cutters again after heat treatment? I grind cutters for a living, and I would think a dressing up after the "pickle" to remove scale would yield a better cutting edge. Be interesting to see what you make with those. I'll be watching for more content.
Hi, yes I gave them a final sharpen with a diamond file after hardening.
I just saw the thumbnail and the first 5 seconds of the video and already went trough "no way", "jooo wtf" and "this is brilliant".
#1 also good for rack and pinion...
