Great idea for a new tool! Thanks for sharing it with us. You said something like, "I'm going to stop yapping now so you can enjoy the video." ...I can only speak for myself, but please don't stop "yapping!" The more verbal description you include, about what you're doing and why you're doing it the way you are, the better chance I'll have of understanding what's happening and why. I'd much rather hear extra commentary that explains stuff I already understand, than to risk missing out on some subtle design feature that I didn't pick up on by just watching parts get made.

Your mechanical engineering is amazing. I have nothing to do with lathe machines and machining parts on CNC or manual lathe machines but I like to watch when a crossive and rusty steel rod turns into a shining steel piece, cutting, making teeth, and other stuff is so fascinating. I liked your video. It is so beautiful and designed to achieve the job. Great! thanks for sharing.
Back in 1998 had to make a device to cut 60 internal slots in a blind stainless hole. 45 mm bore x 75 deep. Put a slitting saw on a chain drive attachment I made for a Bridgeport style mill. Cuts were 6mm deep. Had to get hss cutters coated with Tin compound, used 800psi straight cutting oil. Took about 90 min per component. Made thousands over next few years.
When we made this kind of 90 degree drive we used a very small roller chain for the drive. That way no slippage, up to the strength of the chain you use. We made them to cut internal keys on a CNC machine but this gear cutting idea is a good idea. And with a proper sized cutter a key way could also be done as well.
For my hobby applications it's already overkill :) the groove in the pulley is deep and the belt does not touch the bottom so the more tension the more the belt is quizzed between the walls; the belt does not slip even when doing a 2mm DOC in brass.
There are some changes in relation to our Mexico project. I'm currently working on a video about this part with spiral OD features. When I post that video I think that I will talk about that in the video. These changes have more to do with my shop here in Houston but it all relates to Mexico as well.
Every time I watch your videos, I wish YT would allow me to like it more than once. Awesome project, glad I could contribute to it! The indexer came out very neat! I am waiting for the day you will get your well deserved place in the clickspring league! 😎
I didn't make a set, also the dimensions are specific to my needs and my mill. But you can start with the requirements of the tool (like what is the minimum diameter it has to clear, what sort of cutters do you have, what construction materials are available to you, your mill design, etc.)
Thanks for the reply, I still understood that you hadn't made the drawings, otherwise you would have inserted it, I'll start building it next week, it's very useful and takes away a lot of problems. Until next time
Nice. I have been thinking about making a fishing reel with a planetary gearset and was considering putting together something like what you have done.
External gear cutters can't be used to cut internal gears. The geometry should be inversed so that the internal gear tooth is actually the shape of the gap between external teeth of a gear with the same tooth count and vice versa. Yes, the internal tooth's flank should be concave, not convex. Closest you can get is to always use the rack cutter and don't make gears with a low tooth count.
@@MF175mp exactly, you'd either have to put in additional backlash or you will get periodical tight spots. Worst of all, the backlash/tightness will be depending on angle between gears. A perfect set of gears will have the same amount of backlash/tightness everywhere. But it all depends on the application.
great video and great project! Thank you for this! But please get some good taps! Machine taps are so much better! You can also do it by hand. You can cut in one pass and don't always have to back off to break the chip. The thread is a dream afterwards.
That is very Cool! I've been playing around with how to build that tool and was thinking of using a worm drive, The belt looks to be a much simpler approch. Nicely done!
Very well done project Anyway, with this kind of cutter you won't achieve the right tooth profile for an internal gear. I don't know if there even are cutters for internal gear teeth. Basically the curve would have to be convex instead of concave. It will propably somewhat work, but the gears will never run smoothly like this. You could maybe try to make your own gear profile cutter, I've seen it being done on Clickspring's channel, but figuring out the right geometry is not trivial. That said, I think your design would have the advantage to be able to make helical internal gears as well, which would be extra interesting.
Excellent project, well executed. Thank you for making the video and posting it. I'll likely be plagiarising you soon! I'll likely use a fine pitch cogged tooth drive belt. If I'm not mistaken, one of the cutters in a full set of these cutters are for "infinite" number of teeth, meaning a straight rack. That's probably the best one for this purpose too.

Thank you for sharing. The threading part, minute 15, is that part of the video slow motion or just slow machining? Shouldn't the thread direction of the shaft be the upposit direction of cutting blade?
The internal teeth made by a normal cutter do not give the right tooth model. Design and draw the right tooth curve eg by Autocad. Then grind a cutter. the internal teeth shall have somewhat hollow sides, large dia internal teeth may have flat sides like a rack.
Same as an external gear but the outer diameter becomes the inner diameter, I used the same number cutter minus one. An external gear of the same tooth count and module should fit perfectly in it. I did not have any reference as well; this is all just by my findings, but for the application I need it for a cycloidal cutter will do just fine
Hi Sir, This is an amazing project. May I ask if you have some of the layouts of your project? I would like to make one also for my workshop. Thank you.

@@botavictor5832 was going to mention cycloidal. is all good :) fine for clockwork. only reason id go fly cutter is can do keyways, splines etc. yes, the form cutter is far faster and smoother though.
Don't try don't waste time and money and hard work,,,internal gear this way will not have required profile we in ludhiana India, tried this 40 years ago,,,ultimately had to go for gear shaper machine..
This works very well with cycloidal cutters for clockwork, also a fly cutter with the correct profile can be made. What you see here works perfectly for my application.
60 years ago, for Christmas, I asked for a Spirograph, you have made the same thing here. Thanks for bringing back a fond memory. Regards, Bernie W.

The whole trick is to use both sides of you brain. necessity is the mother of invention.

Great project, thanks for taking the time to film and take us along with you!
Like the use of bearings for filing buttons 😀 tightening rod thing might be a tommy bar? Nice job look forward to seeing what you do with it 😀
Nobody has mentioned that the best part of this design is that for milling machine lacking workshops, it would work on our pillar drills too.
Well you still need an axis to advance the cutter
And you need a milling machine to make it!
Truly a brilliant idea, I hope that you publish the drawings as soon as possible so I can replicate them, my warmest compliments

Прав,чертяка!
Idea - if you have trouble with fused belts breaking, make the cuts at an angle. The surface area will be increased.

Very informative, and very well thought out! Thanks -- and you have a new subscriber!
That a great design , like your setup you do a great job
Very well done, the part and the video equally.
What a great project! Very nice work 👍
Very nice! You gained a new subscriber today. I hope to see more great projects like this in the future.
I approve of arc-second precision when making chamfers.
Awesome! Nice and relaxing video : no bla bla, no shitty music. Interesting subject and very good view angle and rythme. Congrat, New sub🖖👍👌
Great idea for keycutting.
Very cool, I always wondered if there was a decent way to do an internal without a shaper

Yep, no. 8 cutter is what I used (135 teeth to infinity)
Very nice Spirograph much better than the junky plastic ones :)
Btw, I like your style and content. Subscribed!
Great job !
Nice one, only one thing can cause problem - gear cutter can losen the nut, but looks like it work out fine :)
I can always use it inverted and cut in reverse :)
Or just flip it - nut on the bottom will tighten it self@@botavictor5832
Nice work, 👍

no slow motion, the spindle is hand driven

Sorry to disappoint
@@botavictor5832 Really great project. Do You will make video about divider?
@@ttnd3d_387 No, there are a lot of videos covering that (and I didn't film anything while making it)
Woow amazing, I have a question does the geometry for a external cutter it's the same for a internal cutter?
No, it's not the same.
@@MF175mpthanks, I think there are no Comercial horizontal cutters with the internal geometry
The internal teeth made by a normal cutter do not give the right tooth model. Design and draw the right tooth curve eg by Autocad.
Then grind a cutter. the internal teeth shall have somewhat hollow sides, large dia internal teeth may have flat sides like a rack.
Nice project 👍😀
But. How do you calculate a inside gear ?….
And the cutters ?…
Is there a link to information on this?…
Same as an external gear but the outer diameter becomes the inner diameter, I used the same number cutter minus one.
An external gear of the same tooth count and module should fit perfectly in it.
I did not have any reference as well;
this is all just by my findings, but for the application I need it for a cycloidal cutter will do just fine
A great book called Gears for Small Mechanisms has details on internal tooth forms. Check Abebooks for used copies.

❤❤❤❤❤❤👍👍👍👍👍👍👍
Would an EDM setup be another option for making that internal gear?
Yes, it would even better for certain parts where there is space for the wire to exit
but comparing the cost... :))
🤯🤯🤯 IMPRESIONANTE
Yessss👍👍👍🥰
What is that DIY belt made from? What do I search to buy some? Thanks

Where did you find the small diameter gear cutter?
e-bay, from some Ukrainian seller, set of 8
kick ass
unfortunately no cutter will produce the ciorrect profile... involutes dont work inside the PCD, and the tooth shape is "inverted"... even the rack is still not close. and they often use a different pressure angle.
oh sure, it works, but its not the profile required if you were to zoom in/go up a few modules.
seems its a better approach to make this as a fly cutter rather than a form cutter. can always use any old bit in it then ;)
i like it though. always meant to make something similar.
This is mainly for clockwork stuff where the plan was to use a cycloidal cutter (also disc cutters are much faster and less noisy than fly cutters)
@@botavictor5832 was going to mention cycloidal. is all good :)
fine for clockwork.
only reason id go fly cutter is can do keyways, splines etc. yes, the form cutter is far faster and smoother though.

Yes it does, and for my application a cycloidal cutter would have done the job as well

Why not just buy a spiral graph from the toy store.
That spirograph was made just for testing purposes,it was not the goal of the build

cutter can be placed the other way and spun in reverse -> gets tighter
You can insert a musical accompaniment. So that it doesn't look so boring
