Hi all,
I need some planetary gears for my model ...
I had an old battery-powered drill with this type of reduction, but unfortunately too high (1: 6) and non-standard metric module (0.7), so I decided to turn my lathe to a broaching machine ... I used the gears of my lathe that give me the chance to do almost all possible divisions. Now I can produce my own planetary gears with a 1:4 ratio!
If you have patience, you will find more videos on my channel of this work ...
I leave the link anyway:

The method is so simple, but it's the imagination thats the clever part. This is the work of a clever person and a proper engineer...
At my shop, we have an antique machine (made like a tank ahah) from the WW2 era that can make pretty much any gear , so it would be a total waste of time for US to use that method... but it's still fascinating to see how people come up with crazy idea to get the job done ahah XD.
Excellent work performed. Great project.
Excellent, you've made my job of obtaining change gears for my antique lathe much easier!!!
Love the sound of straight cut gears...!
Normally, I find it easier with some steel wool, #1 knitting needles, bottle of sherry, rocking chair on the verandy and knit 'em up, before bedtime.
Oh, but your method seems nice, too.
I too wondered about the indexing. I have used this "broaching" approach for cutting keyways quite often. Nice example of patience - been there and done that! Grinding the cutting tool musty have been more than critical. Most interesting, thanks.
Amazing model and really clever technique for making the gears you needed. Could you please make a video of the setup and how you ground your cutter to the correct shape.
You sir, have infinite patience. I have no idea what these gears are meant for but I enjoyed watching this video. Well done.
Normally here in the US that process would be called shaping rather than broaching. You did a great job of grinding the cutter, considerably harder as the size gets smaller. For what you are using the gear for I don't think it matters that it is not a pure involute form.
That is so awesome dude!!!! Thumbs up on this video dude!! Man I have thrown away so many gadgets because I couldn't replace a gear on them,but after watching this video I'm going out and try to buy me a cheap little lathe and practice on it until I get pretty good at it and then maybe move up to a more expensive one and really get into.Thanks dude.
James Parmenter May your dreams come true!
I knew a man who was sharpening details on the lathe and did not include the engine. It was in the forest. You are the second craftsman!
hard on the crossfeed, but im impressed, always happy to learn something new for my trade.
I have used a similar method for broaching key seats in blind bores, it's slow but gets the job done. Thanks for the video!!
Hi Jeff, you can find all links reading this video info ;-)
Nice work! Quality craftsmanship.
Великолепен клип!
Окончателно ме убедихте,че независимо в коя област от живота,любовта към нея е в състояние да извърши истински чудеса.
Щастлив съм,че имах честта да се запозная с професионализма Ви!
You have the patients of a saint
Patience.

thats is a lot of work... wow, thanx for filming and showing us this. Wish I had taken shop in school, but I don't think they offered in the little town of Palestine. Never heard of the term "broaching". Thanks again.
Thanks for the insight. I had only considered milling the profiles. This has been very informative.
Cool gear! Patience and elbow grease...there MUST be a tool for that! Thanks for recording it, looks like a great project.
thank you!
I have learned a lot watching your informative videos. Wish I had a fraction of your metal working knowledge. THanks
That is so very cool that you made a gear without super special tooling or a milling machine!
Noce work! Very inspiring, now i have to go out in my shop and make a dividing-head attachment for my lathe :)

Great job. It takes patients to do that kind of work. I am guilty of it too. When you get to the last couple of teethe and start taking too much each pass to get it over with, and that's when you make mistakes. I am just now recovering from amputating my thumb on a lathe at work. Lost my concentration (a coworker came up and was asking questions) and ZAP! Off came my thumb. Thank God they were able to reattach it and I will get full use eventually. BEWARE!
great work, thanks for taking the time to teach
seriously.... who watches a video like this on TH-cam then "thumbs down" it? really? Very cool.
Good work Dude!
And I love that asmr
Good process of gear cutting / broaching on lathe
+Sanyasirao Senapathi Thank you very much!
awesome.. i would have never thought of that.. thanks
Nicely done, however i would never have the patience myself to broach gears this way unless I was making only one perhaps.. I would go the gear cutter route, and some kind of accurate indexing system. You show that they can be broached and very nicely done.
Looks very good.. I like to see your dividing setup
Great work 👍👍
Thank you for the video. Would have been interesting to see how you sharpened your chisel. Gives me an idea on how to make one when I get around to making my own lathe.
sorry man not mean to be negative,and nothing special but long time i want to say that quote .
respect for the great work u did,
from a guy that love machining
I also learned from other video ... I am pleased that my videos are helpful to others.
Thank you!
Was the initial trouble after first assembly because there is not having enough backlash? It would be nice to know the pitch of the gear and the material being used.
I have the impression that English is not your first language. Thank you for including the captions so that we can follow along. It is a very interesting process that you have developed. Your video captures a lot of interesting detail. The lighting and the framing is quite good. I will check out the other video, I hope that there is information about how you create the cutter.
thank you, I tried not to stress too much light passes by the lathe and using a lot of oil. the lathe fortunately did not damage.
I do not think of having to do a similar job again ...
Nice! I wish I was that good at turning out parts on my lathe.. I got a mini lathe for Xmas and all I've figured out how to make is screws
Hi Steffan, a thousand thanks for the comment you left!
I'm glad that my video will teach you something!
مرحبا لدي سؤال كيف تقسم عدد اسنان الترس
great job man perfect work 👍
I am very happy to give you some more ideas! My knowledge is only the fruit of passion!
Great video and great skill.
Lovely work!
Complimenti Claudio! Sembra il pignone degli automodelli TAMIYA..!
your effort is appriciable,good work and gear teeth also not bad,before grinding its OK.regards.
great work man good watch
very nice i cant wait till i start using my cnc machine i got like 2yrs ago and im yet to start on all my designs
wonder how you got the gear shape into the cutting or broaching tool, very good video . thanks for posting.
Great idea if you're in a pinch and don't have a shaper! 👍🏼
Muy, muy bueno su clip, Claudio.
Agradezco por compartir, su conocimiento.
Pregunto: cómo preparara el buril??
De nuevo gracias, y no deje de publicar.
Atte.
Alberto, saludo fraterno desde Argentina.
Very cool. Just a hint for when youre counter sinking or counter boring on a lathe: slow your rpms down and itll squeal and chatter less. Another tip: use only the tip of the centre drill to spot a hole, the shoulder doesnt do your drill any favours (drills are ground at 118deg incl angle and that looks like a 60deg centre drill (120 deg incl angle), that little difference causes the drill to start funny and its slightly off centre as a result. Great work!
Thanks for the tip! I'll try to put it into practice
Descartando a tecnologia robótica : excelente atuação de torno !!!!!!!!!! gostei muito
Very nice job!
Amilton Almeida Jr
Like Butter! Great job yo!
Very educational, thanks for posting!
Excellent job
this is awesome! i wonder how you make your broaching tool? any videos?
I will make a video as soon as possible
i'd like to shake your hand man.. such a work!!
thanks man!

Bravo kolega, ( 5+ )
when you ran it with the Drill, you could have added some emery paste between the gears, that would have smoothed out the contacting surfaces...
Nice Idea by The way... :D
the problem was due more to the machining burrs that the contact surface, the aluminum pieces that I have produced previously having no burrs worked straight away. I preferred to use only oil to avoid creating excessive play. thank you to comment it!
Emery paste not good for gear boxes!
I meant that using Emery Paste only for the Initial Running In.. to remove any burr, and smoothen the contacting surfaces..
This was the most common method used while matching the Valve contact faces in an Engine Head.. the Emery paste would grind the contacing faces to a near mirror finish, and give a leak free joint..
In case of the gears, the smoother the contacting faces, the lesser the friction, after applying a little bit of oil while normal running..
putative3 It is when you are trying to open up gear lash and you remove it all when you are done. Lapping tight gears is normal when you aren't making parts for the Space Shuttle. I had a custom gear set I made that I was off a thou and a half overall cause of the tail stock and was too tight. After lapping it was smooth as glass. I flushed the gears really good, and it gets an oil change every year. That was almost 15 years ago and it is still in operation to this day. It has had more than one seal put in it and a shaft or two, but the gears still mesh great and the magnets inside the case stay clean.
I'll try to upload a video soon ...
Meanwhile I can tell you that with the help of autocad I designed several 3D models of the teeth, then interpolating them I found the right profile. due to the small size I could easily approximate the curve in an arc of circle and then with the help of grinder mounted on milling machine I modeled the HSS tool that you see in the videos
Cheers! Thanks a lot for the info and knowledge.
Hi all. Many viewers ask me why I have used this method and not a mill and dividing head ... the topic was treated repeatedly over time. This method has been invented to produce internal gear and later adapted to external gears. I could not use the mill because these pieces are too small to be machined precisely in that way.
I invite you to watch the video th-cam.com/video/4QLftRlHxj4/w-d-xo.html
Thank you very much!
hi there claudio
i just have one question
how did you manage to get an accurate distance between each tooth
how did you divide it accurately on the lath?
hope i managed to get you to the point
+mohamed farid I invite you to watch the video th-cam.com/video/lqreWsmXG4k/w-d-xo.html
+CLAUDIO GRASSI woooow
that's awesome 😲
How you could sharpen cutter for involute profile?
CLAUDIO GRASSI
Is this for swing on a model dragline? Also with the size of the gears you are making and the fact that lathes are made to power feed into the part, the little stress you are creating is not any worse than taking a roughing cut. Good job
Wow very nice work. Gear cutting is a fine art. You pulled off poor mans gear and it functions not many can say they done that!
Thank You Rich, that job was just to solve my problem to find particular gears for my model. I hope not to do it again! hahaha
however, it was a nice adventure and a great satisfaction to have succeeded!
is fine, the steps were very light (0.05 mm at a time)
my lathe works great as always.
yes, you can find all in my channel!
Great job. Thank you for sharing
Wow love this. I love my lathe best tool ever.
How is made the tool profile? Oops I forgot to say , Great job ! excellent !
+Arthur Silva Thank yuo, I simply designed shape and then I grinded by a piece of HSS using the grinding wheel mounted on the milling machine
I am answering that how to make accurate tool profile. The easiest way is to do the wire cut EDM on your tool. The CNC machines has the software to get accurate gear profile of your need. Good idea to broach a gear on lathe machine but today one has a lots of other fast and accurate methods to make gears.
very nice work great video thanks for your time
I read the comments on your page, I have nothing else to add!
Super cool man! I love cutting gears and gearing. What are these reductions going to?
Do u rotate the chuck with ur hand ,if so hats off to u!!! Great job
Grande profissional ,dou valor !
Impressive!
Hi Drew,
It's not milk, it is a mixture of a special soluble oil and water used for cooling and lubricating the workpiece and cutting tool. In the industry I worked in we used to call it 'slurry'. - Never be afraid to ask.
They say the Lathe is the only machine on Earth that has the ability to reproduce itself. I love my lathe, it's my baby. Don't mess with my baby!
Very helpful video. Thanks
Thank you for sharing this!!!!
nice work, thanks for sharring it :-)
Nice work Claudio!! I have one question: how do you measure the angle for next tooth on the lathe?
I have done gear cutting in hobbing gear shaping gear milling .But this is marvelous.good.
thank you!
Not bad? This is great!
you are my hero!
You could possibly leave 0,01-0,03 and then run the gears with fine lapping compound to get perfectly set and fine ground gears... Nice
God that looks mind numbingly tedious. But very useful to know how to do. Thanks for sharing.
Hello, very good video !!! Excellent. I consult you, how do you manage to turn the lathe plate with the specific degrees ?. And on the other hand, how do you manage to lock the lathe plate at the time of machining the gear?
Thanks and greetings from Argentina !!!
I Raul, see this video... th-cam.com/video/lqreWsmXG4k/w-d-xo.html. I used the gears of my own lathe.
Wow, you got really excited there at 4:20 . XD

Have a look at my channel: th-cam.com/users/BUSTYCLAvideos for more videos! thank you a lot!
Thats a great idea and all, really a good idea and simple. But don't you think it is a little hard on the took carrier?
I would say great job! Now I feel kind of apprehensive to do that to my 1941 Lathe machine! but sweet job!
Here it is so a turner, Supreme Class
It is beautiful, you're a genius. How did you get the idea?
Muito bom parabens pelo trabalho
Nice work. Do you grind your own broach tools?
Hey good work! Very interesting how gears can be produced even on a lathe. Never saw this before. But to me it looks as if you do not work with a lathe very often, or at least never had a professionell instruction. Different cutting speed for other turning diameter, feed rate, so on. Or you just don't care thinking "well it has to work in the end". Sorry. I'm german... i like to do things perfect!
Although great Job, keep going!
standard steel, I improved measures, on paper reflects the expectations, hopefully good!
Your idea is good👍💯❤👍👍👍👍👍👍👏
