Cool, I'm in your video! ∙D
(Those darn lasers were red, though...)
HOLY CRAP! Please come back! We miss you!
Thank god this got pinned. I was unable to remember the name of the channel and google failed me.
Uu from Betelgeuse
i cant believe youre still making videos. what is this? im in a weird youtube rabithole
Cyclops?
My 15 year old son watches you all the time. "Quit watching Old Tony" said no parent ever.
He's not old enough for ave yet
Machinist 4375 he could oxyacetylene weld aluminum at the age of 11
David Parry he can only swear in two lol
As a 15 year old son, i really like this old tony too.
My 15 year old daughter doesn’t watch TOT so I have to watch for her🙄
I’ll have two number 9s, a number 9 large, a number 6 with extra dip, a number 7, two number 45s, one with cheese, and a large soda.
Unfortunately, that is outside the scope of this video.
@Mai Mariarti More like masquerading as a larger than normal amount of visible gas.
Best San Andreas cut scene!
Big Smoke in the house (well… drive through).
All you had to do was follow the damn (gear) train, CJ.
"If you had to rewind to hear that again you should stop this video right now"
Why you gotta personally attack my low attention in introductions bro
Yea. I was reading comments.
I got stuck on The Jetsons reference or at least my attention did which made me want to rewind... but I didn't! LOL
I'm Italian and I do appreciate not only your humour but also the way you make a person like me, a complete stranger to any concept even vaguely related to metal working, intrigued enough by the topic, to the point that now I'm thinking to buy a small lathe and start working with it! You're great! Thank you!
Could you please explain the part about gears again
He he you are funny.
So, how do I go about nominating you for teacher of the year?
I'm serious. After 4 years of college (one of which in a physics/engineering masters curriculum) and three years in grad school, I'm hard pressed to think of one professor who could do as well as you do breaking these concepts down into easily digestible tidbits.
Thanks for all your hard work on these! Most of us really appreciate it!
Except my wife. Keeps reminding me of everything around the house that needs to be fixed while I'm watching your videos.
Second this! Even the part about nominating Tony for Teacher of the Year.
Tony of the year.
Exactly what I just thought of - after 5 years of engineering in a German university :D
Wholeheartedly agree. Please repeat with the gear hobbing approach.
Agreed! Kids would totally learn something from these fun videos - I love Tony's videos!
I doubt you come back here to check out old used comments like this, but I digress... I like to watch this video every few months to get geared up for using a dividing head. I still haven’t professionally used one yet but every few months I get ready! I appreciate you ToT.
45 years as a machinist. have always enjoyed when i got to build a gear, i learned allot in the video. thanks dude. you're never too old to learn.
I can only imagine you at parties...
*door bell rings*
Oh Hi T-dawg! So glade you could co..... why do you have a block of metal and some string?
Also where are you pants?......
Or..."Is that a lump of metal in your pants or are you just happy to see me?"

@@ThisOldTony lol. Just trying to expand my horizons during quarentine. You know how it is.
This explains why youtube has been showing me both your videos today
soon enough we'll be seeing zack cut phones with gear cutters
@@ThisOldTony our math teacher was german,mr zemburgs. ..if,,you did something bad, he would give you 2 #. to multiply together, 100 times. like 7429 over 539. mess around in the machineshop.. go make me a 63 tooth x 7" gear . yup,that would be worserer..
After getting my teeth into this I'm a lot more cognisant. Now if only I was more driven.
Throws pop corn at you lol
No
stop with the gear puns im laughing up blood
Stop being an idler all your life.
Such a high ratio of punny b astards in here. This could probably just go round and round. I think we were all cut from the same stock. I'd be hard pressed to change gears on the topic but I'm ending this transmission now.
"Everything You Wanted To Know About"
Fun fact:
The Modul - System is directly copied from the DIN (Deutsche Industrie Norm => German Industrial Norm)
The Z means "Zähne" => teeth
The DIN was developed to join together the German Production more tightly and make parts and tooling interchangeable. (why have BFS,UNF,UNC,NPT, BSP, JIS,SAE and what not bolts if you simply could use DIN-bolts) But also to make the German machine parts and tools useless to the enemies by making everything a little bit different.
But the Prussians where to damn efficient. ;-) French and other started to copy the norms and the ISO (International Organization for Standardization) was established. Many DI-Norms where directly copied to ISO.
Oh that must have hurt any Frenchman who knew the history. Accepting ANYTHING Prussian ? How could they ?
DIN = Deutsches Institut für Normung
@@nivram6092
You are right an wrong. First DIN was the shorthand for "Deutsche Industrie Norm" as seen in "DI-Norm 1" and the organization was called "Normenausschuss der deutschen Industrie". It was renamed multiple times. In the end it was decided to use the abbreviation DIN (Deutsches Institut für Normung) as Name. (and all Norms now are called DIN-Norm) But at the time the ISO was established DIN was standing for "Deutsche Industrie Norm"
Great video as usual.
why have I only come across this channel now? This is some of the highest quality content on TH-cam period

Tony, as all your videos are, this one was excellently produced and remarkably informative. With as much humility as is possible in a comment about how much I know, I would say I have a fairly deep knowledge base and understanding of machining for someone who like yourself is not a professional machinist. However the relationships of diametral pitch, cutter sets, and the other various technicalities of gear machining were one of those topics that I generally understood, but wouldn’t have said I was clear enough on to be comfortable trying to explain it. Like you do with every subject, you made this incredibly complex subject very easy to get one’s head around and allowed it to finally “click” for me. I even wished you had gone ahead into the topic of pressure angles because I’m sure you would have made that subject much more comprehensible as well. I don’t know what trade your day job is, but you are an EXCELLENT teacher! I sincerely thank you for all of the time and effort you put into producing your videos and publishing them so graciously for all of us. Not only are they valuable as a learning resource, your razor sharp wit and perfectly precise timing with humor make your videos probably my favorite content to watch of any media! Great job! And by the way, this video was not too long at all in my opinion. I would happily watch any video you put out of twice this length and still not feel it was too much!
A bit late of a comment but i would assume this(youtube) is his day job..He should make enough on it anyway.. What he did before that though.. Probably(hopefully) involved some teaching. :P
@wvmotorider
Bravo, well said!
Back in the late '80s, if I had Old Tony, Clickspring, and Matthias Wandel when I did Design and Realization (aka Shop, in both wood, and metal; you were given a brief, and not only had you had to draw a design around it using a drawing board with a parallel motion, etc, but then you had to build the said thing off of your own drawings ...), I would have learnt, and retained, way more; but watching all three, plus Abom '79, Stefan, and many others, have jogged memories of almost 30 years ago ...
I wish I could get into being a machinist, but due to space and budget (but mostly space ...), the closest I can get to is a Sherline lathe and mill. I am eyeing upgrades for both, but, if I want to go all in, I am guessing on around $8k+ for both, inclusive of enabled manual and CNC operations ...
@@nigelft hey! Are you an engineering??? I am a young kid aspiring to be an engineer! Please tell me if engineering is what you have to do to be in the path of a machinist??
@@abdulkarimhalai6708 I'm sure there are sources of better answers to your question here, but .... a machinist applies engineering to produce a product. Mostly they learn through apprenticeship. The choice of if and when to learn engineering principles is up to the individual. I hope this helps you.
hahaha the eagle cry at "independent" @6:05
Can you explain please?
@@manuel56354 The sound was for America.
It's a sad commentary on the world that TOT doesn't have several million subscribers. Knowledge, solid camera work and editing, and continual string of subtle humor all combine to keep me LOCKED onto these videos and coming away smarter a half-hour later. TOT is what public school should have been. Thank you Tony!
I hope this video was worth the loss of street cred from the cycloidal gear folks.
Those darned horologists and their terrible teeth.
Heretic! I bet Nicola Tesla made them work !!1!
This old tony! I learnt something! All jokes aside Sir. I'm not even into any of this, but just watching this was very inspiring.
Tony, thank you so very much for the videos you make. Though I am laughing continuously throughout the videos I am also learning so much. You truly are a gift to the TH-cam community.
Mechanical engineer here from Germany. I suffered through prehistoric textbooks from my prof to learn this. I wish i knew this video existed for so long already. This video is gold!
i met an involute once , he worked in the hardware aisle of home depot.
Those are some fine looking shop-made gears my man!
I've designed gears and drive systems in my day and this explanation is the most scienterrific way anyone could explain this topic.
😄
Great videos Old Tony!👍
I got the Mini-Lathe video recommended on my YT home page, and I'm thoroughly enjoying watching this channel. Man has a great sense of humor and is very informative.
"Cosmo Spacely".
We are not worthy.
Caught that going by and about fell out of my chair.
Old Tony,
Thank you for the gear tooth tutorial. I spent a career repairing and maintaining machine shop machinery. We were primarily a milling, turning, Blanchard grinding and cylindrical grinding shop, but we did our own gear machining. We just machined spur gears, but we machined straight and helical gears. When I started, we hobbed on Barber Coleman's and shaped on a Fellows. We moved on to CNC hobbing and then to grinding our precision gears. Our hobbing machine was a Pfauter and our grinder was a Gleason. Gleason is far better known automotive gear machining, but they wanted into the spur gear market in the 1990's. They acquired Pfauter and had Okomoto make their grinding machines. This relationship had me make multiple trips to the Gleason plant in NY.
So I repaired and maintained gear making machinery, but I was never trained as a machinist. I am an electrician/mechanic. Your gear tutorial was just the ticket for a retired repairman who is now trying to be a hobby machinist. I recently purchased my first super spacer, but haven't used it yet... But it did give me a legitimate excuse to purchase a set of 5C collets.
man, your one-liners is what I watch your videos for
I have started saying "it is outside the scope of this video" whenever my boss asks me something that I do not know the answer to.
This is the weirdest Clickspring video I've seen so far.
*best
I have a weird set of antennae which seem sensitive to slightly different things than most people (ah, life on the Spectrum!)I have met, when I watch or rather"watched"(past tense) Clickspring I felt overwhelmed by what my indicators were warning me was queasiness-inducing self-indulgence ( polite verb ) it was, initially the way he splashed that Steel Blue all over the place but the longer I watched the more queasy I felt until all I could think of was "click unsubscribe" which I did.
@@GregorKropotkin-qu2hp have you gotten help for that yet
Before I watched this video I knew 0 about gears now I can say I know 1 about gears
In a binary world, you are The Gear-All-Knowing-Mighty-God!
... while in this world you are as a gear with Z = 1
Great explanation as always! Pretty much the only TH-cam videos, that after I watch I don’t feel like I just wasted my life away. Keep ‘em up!
This video is what the internet was made for! Love the content. Love the humor. And love the way things are explained. Don't ever worry about "insulting [our] intelligence". Not everyone is in the same place intellectually and experience-wise.
Keep-'em coming!
Spindexer was my DJ name back in college.
I learned about gear machining in trade school and thought, "I'll never need this crap". Two years later... ran a hob and shaper everyday for the next 5 years. THIS is some surprisingly valuable info. Thanks, Tony.
We never even got to a use a square collet block at my trade school. Suffice it to say, any dividing head, spindexing stuff is on the job learning for me.
Omg why have I not found you before, I've never laughed so hard, as an engineer, I now love your channel, thank you so much.
Love the video! I cam across the mini-lathe one before and I definitely appreciated it. This one is a hoot. Great sense of humor and you explain things very well. Information is layered up and provided in terms most people are able to understand.
As an aspiring beginner machinist, I have now subscribed.
Cheers!
Fun fact, there are a couple 3D programs that have cogwheel shapes with adjustable settings for teeth, addendum, pitch, module, etc.
You just explained how to use those settings better than the user manual. And it WAS written by a dude with a degree in physical therapy. Probably.
@@chris0tube Autodesk Autocad and Inventor have it, pretty sure SolidWorks has it too.
I use Mattius Wandles program and import it into whatever.
Oh I see.Mattius didn't have a degree in physical therapy. That's how he ended up with tendonitis.
We asked Tony if he had a degree in theoretical physics, he answered that he had a theoretical degree in physics. Then he said he had a physical degree in therapy. After some stammering and mumbling about imperial decrees on therapy we hired him...
He has the only candidate. It was a very confusing day.
Many of Autodesk's CAD programs have this feature available. I'm not overly familiar with CAD programs, though.
I was actually referring to Cinema 4D.
"This video is already too long..."
UNPOSSIBLE. Thanks for the great videos ToT, truly a gem of the Internet!
Thanks for taking the time to convey the detail. Chuck the folks that don't like longer videos. Love your sense of humor.
I searched far and wide for atmost 5 days I did not get that now I was able to , this is the best explanation on internet about indexing mechanism 🔥🔥🔥🔥
You make a fantastic teacher. The way you share your knowledge using humor and props is better than any teacher I've seen. I absolutely love your videos
Dear This Old Tony,
I've been an avid watcher of your chanel for some time now and I always love it when you create every-day components like the pasta machine for example. I'm personally really interested in knife sharpening and stumbled across guided sharpeners some weeks ago and although I still prefer good old hand-sharpening, it would be incredible to see a heavy-duty, overengineered version made by you!
Greetings from Germany and thank you so much for your commitment and great quality videos that never fail to entertain!
Lucas Kramer this would be awesome
I agree that pasta machine video is what got me hooked on ToT.
I love your videos! They're amazing. I've discovered a passion for machining and engineering. I enjoy the editing style and the video format. Thanks for providing this to the public.
Absolutely fantastic.... usually more interested in the welding content and yet here I was eating this up and loving every bit of it. Thanks for breaking this down, and keeping it entertaining while teaching!
I want so much that you keep working on improving that mini-lathe! It's so entertaining and interesting to see you "updating" it and making it better ^_^
same, how many improvements does it need to be decent?
@@ToreDL87 It does not matter. If TOT can put up these vids it can show us little people that are short on space and electric service(110 only) how we can make things on a metal lathe. That we can do for a reasonable entry price with half way decent accuracy.
@@dieselfueler Depends, for decent accuracy just put a chuck on a DC motor bolted to a piece of railway track and mill it within .5mm then lick the rest of with sandpaper, (field solutions the old timers used, but have personally done that a lot on rackety mills).
I'm talking about Tesla-style facebook and selfie while driving in corners don't think about it accuracy, what mods are needed for this mill to get good enough accuracy that you can just mill it and be done, for possibly maybe lover-like equal treatment.

Absolutely astounding. Never learned so much from one video. Thank you so much. I'm not a machinist, but I'm researching mini lathes to add one to my shop. Also watching your CNC videos as I want to build a small one too.
This old Tony does a video or two on mini lathes, search them out, then don't buy a mini lathe.
It’s been 25 years since I graduated from comprehensive School and this video brought back all the math in such a practical way I think parts of my skull blew out!
This is an extremely useful video. Even if the gears didn’t fit. Mine finally did! 😁

If ever a video needed a montage segment with a spinning clock, coffee pots being drained, calendar pages falling away, and "My dearest Emily..." voiceovers, it's the cutting-100-gear-teeth video.
It's not too long- there a tremendous amount of understanding and knowledge - and starting out, every single bit is invaluable - and I have gotten what I couldn't get elsewhere from here , so don't be negative about the length because it was all important for my developing understanding of gear development and using a mini lathe, which for a first video that I've found that's what I'm going to be needing a mini lathe for, the information here was invaluable my friend, and thank you for your patience making this. Much appreciated!!!!!!
Geared down to my understanding. I'm racking my brains for a complement. I'm left in a bind.

You remind me of my high school shop teacher, he was very articulate when it came to explaining the basic processes of making stuff. Weather it was wood, metal or electrical devices he did it all, and with a sense of humor to boot. Though he never joked about racks.
Racks are no joke ;)
I don't have the means to get into machining at all, and have no knowledge in that department, so I absolutely appreciate you "insulting my intelligence", and your strategic wit which made understanding gears go down much smoother. I have no concrete idea of how to use my newfound knowledge, but I suppose that's what late night Youtubing is for.
This is such a hilarious video! I love your sense of humor in describing all of this cool stuff. Definitely not boring!
I literally bust out laughing at your humor in parts of your videos, incredibly educational and with a touch of funny. You sir are a great teacher.
best gear cutting vid ever just starting on dividing now feel i got a grasp of what is going on thanks Tony
Enjoyed learning from this and the light humour made it more enjoyable. Thanks for posting and I look forward to seeing the others.
I was always slightly interested in machining because of my mild steel fabrication background and always thought I was out of my depth trying to learn. I honestly found this inspiring to pursue it in further education and found this very digestible and easy to watch and glad I just found your channel. Look forward to binging your content tonight.
Of all the Old Tony’s, this one is my favorite.
Is there a That or Other?
This is one of the most hilarious engineering channel on TH-cam!!!
What a great teacher you are! You use puns, jokes and "bear with me":s with perfect frequency. And, you started from the very beginning in order to explain the evolution of the technology. A++
TOTALLY AWESOME! just cleared my all the questions and doubts between rotary hear,, spin indexer and dividing head...... Thank you very much for this great explanation....
I'm near the end of the video, both baffled by the info, and amazed by it. AWESOME!
Got to pause a lot. Then smile. Then think. Then learn. Again and again.
Great videos. Thank you. Greetings from France.
I watch from beginning to end with the occasional fast forward or speed increase. Like watching golf.I like learning and your a good teacher.
Keep an' coming!
How the hell did they make clock gears in the 1700s??
I imagine they used a compass, a file and some damn good patience
Very finely honed skills.
Or "horned skills"!
Many engineering institutes go these procedures in a rush!
They made gears long before that! You might be interested in clicksprings channel
They got a peasant to turn a handle very fast to make the lathe go
I'm afraid I must disagree with you, your videos are never too long. Too short maybe but never too long xD
Not only too short, but metric.

I’m always impressed on how a machinist, who’s not required to have an engineering degree to perform your function, can be creative nowadays but, even more impressed I am with the machinists way back in time when there were no examples nor it had been done before professionals to show the way but, beyond our imagination, THEY MADE IT!!! Imagine watching those hits, without cnc, no electricity for smaller machines muscle operated, no special tools/holders what they had to make it instead, and no Amazon/eBay/TH-cam/etc!!!!
Totally amazing!!!!!
Thank you for your very detailed explanations!!!!!!!
