Cool, I'm in your video! ∙D (Those darn lasers were red, though...)

My 15 year old son watches you all the time. "Quit watching Old Tony" said no parent ever.

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.

"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

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!

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.

Could you please explain the part about gears again

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.

That was fun to watch. Thank you!

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?......

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.

After getting my teeth into this I'm a lot more cognisant. Now if only I was more driven.

why have I only come across this channel now? This is some of the highest quality content on UKposts period

"Everything You Wanted To Know About"

I've been watching AvE waiting for Tony to upload, wasn't disappointed 😍

hahaha the eagle cry at "independent" @6:05

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 UKposts community.

Those are some fine looking shop-made gears my man!

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.

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!

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 was going to give you a "like" but that's outside the scope of this comment 🙃

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!

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.

i met an involute once , he worked in the hardware aisle of home depot.

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!

Great explanation as always! Pretty much the only UKposts videos, that after I watch I don’t feel like I just wasted my life away. Keep ‘em up!

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!

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.

Spindexer was my DJ name back in college.

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.

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.

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.

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.

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!

Thanks for taking the time to convey the detail. Chuck the folks that don't like longer videos. Love your sense of humor.

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

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.

Enjoyed learning from this and the light humour made it more enjoyable. Thanks for posting and I look forward to seeing the others.

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 🔥🔥🔥🔥

AvE, T.O.T. and Chef John vids all in less than 24 hours? I'm convinced more and more that one are many and many, are indeed, one.

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 ^_^

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!

My this is the best channel thank you . Enjoy the banter and the info is very helpful as i learn to use my own lathe . Look forward to your videos thanks Doug

"This video is already too long..." UNPOSSIBLE. Thanks for the great videos ToT, truly a gem of the Internet!

Thanks for doing this video, I learned something. I can use tooling from my Hossfeld Bender to do demonstrations on how things work. :-)

man, your one-liners is what I watch your videos for

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!

Good video man I sell gear, spline and Hobbing cutters for a living and you nailed it fairly well.

This is the weirdest Clickspring video I've seen so far.

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! 😁

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++

best gear cutting vid ever just starting on dividing now feel i got a grasp of what is going on thanks Tony

The reference to Earthlings 101 was much appreciated, really miss that series.

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!!!!!!

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....

"Cosmo Spacely". We are not worthy.

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.

This is such a hilarious video! I love your sense of humor in describing all of this cool stuff. Definitely not boring!

I have never worked with any of this but thanks to youtube's recommendations, I'm here and I'm here to stay. Funny as hell i love it.

I hope this video was worth the loss of street cred from the cycloidal gear folks.

That was absolutely awesome, I've learnt a huge amount about gears and how to go about cutting them and, nearly peed myself laughing, you have a fantastic way of teaching and I'm looking forward to watching more of your video's.... Thanks very much for sharing, take care...

Finally a description of the sector arms that doesn't hive me a headache. Most are way over complicated. Very informative.

I like your style, your meme-y, lighthearted style + engineering / DIY / construction / etc earned you a subscriber Tony

The Racks were nice.

Got to pause a lot. Then smile. Then think. Then learn. Again and again. Great videos. Thank you. Greetings from France.

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.

"Note: If you build something that tears itself apart, you probably aren't there yet." Harley Davidson: (Surprised Pikachu Face)

well done, I recommended your channel to my college machine design professor to help educate students on how tools and machine components are actually made to help with the designing process. Love your work

Before I watched this video I knew 0 about gears now I can say I know 1 about gears

Thank you for your support! I learned more with you than all my 30 years career in Mercedez!

Oh man, this really helped me to understand gear better, dividing head better! Wonderful! Thanks Tony.

This is one of the most hilarious engineering channel on UKposts!!!

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.

I love how you’re serious on the important stuff a very funny where it’s okay to be. I just learned the advantage of a dividing head. Thanks Tony, you’re the best!

I laugh nervously at the “Great one more stinkin’ thing I’ll need channel” ....as I wait for my 400lb lathe to arrive in the post. Before I watched this channel I was happy with a cordless drill and a few screwdriver bits. Now I’m contemplating whether a TIG welder will hook up to my standard 13A power supply.

I'm near the end of the video, both baffled by the info, and amazed by it. AWESOME!

Round, bumpy, knobby thing...describes a girl I once dated. She was torquey, too.

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.

Well thanks for taking the time to show this I did learn a few things , Just got the same dividing head myself.

Of all the Old Tony’s, this one is my favorite.

0:28 Love the rebranding! Now that you've become the "GREAT! one more stinkin' thing I'll need" channel, my TOT shirt is a priceless collectible, right?! :-)))))

Incredibly informative, I do really enjoy the way you devlier complex information in an almost universally intelligibile way. That's some talent!

Brilliant video Tony. Really nice explanation. I've read over complicated explanations of gear cutting in books but didn't really feel any the wiser. Thanks.

Geared down to my understanding. I'm racking my brains for a complement. I'm left in a bind.

I wonder why someone would dislike this? Such Unequivocal Brashness Shown Really Identifies Bad Emotions

This was a very instructable video, will keep a watch for your other videos, thank you!

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/UKposts/etc!!!! Totally amazing!!!!! Thank you for your very detailed explanations!!!!!!!

Don't know why but this was recommended to me by the algorithm and I'm thankful it did. Realy like your style. +1sub.

Top gears 👌🏻👍🏻

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.

Best explanation of gear cutters, I have ever seen.... Bravo!!!

I had no idea you were this entertaining! I've been missing out!

This old tony doing what he does best, GOING OFF IN TANGENTS

Tony, your ability to deliver 5 or more semi complex ideas in plain language in a manner that is contiguous such that even I can follow along. Well, bravo🍻

Your videos are interesting and show great skill at machining and video production. I will never use 99% of what I learn from your videos, but it's nice to have a basic understanding of how all these things work. Thank you.

I'm afraid I must disagree with you, your videos are never too long. Too short maybe but never too long xD

It's a lot of small things in these videos that add up to their greatness. The sound editing is no small part of this!

Wow. I'm not a machinist but I learned more from this video than any I've seen in a year.
