After all those years he still amazes us all with yet another way to break a tap, incredible.

Man, I remember when this series started back in 4042 bc. This was long before steel was developed, so it was a lot harder to cut threads back then.

I was working in a music store. We were sent a tympani drum that was missing a few tentioning wing nuts. Was a squarish thread but not Acme. Probably the British Standard Whitworth equivalent. The old gentleman I worked with, who was brilliant, took the better part of a day grinding the tool to cut the threads. I was so lucky to have worked with the man. Though repairing brass and woodwinds, he was a welder, machinist and a tool and die maker. He was 72 when I first met him. I learned so much from the man. He was also a lot of fun to work with. At the end of the day Friday, he'd ask if I had a tooth ache. I'd pretend to hit myself in the mouth with my rawhide mallet and say, "I do now." Then he'd take out the tooth ache medicine, Scotch, and pour a large shot into my coffee mug. One more thing about cutting the threads. We had a big old Boxford lathe. What could be better for cutting BSW threads?

Disappointed that you didn't cover my favourite method of making internal threads. I cut an external one and then turn the part inside out.

Hi tony, I’m 12 years old and want to be a machinist. I just bought my first lathe and started making little projects. Keep on making these great videos.

It's been a long 2021 years. Glad we made it to the next one though.

You have no idea how difficult it is waiting 2021 years for these threading tutorials but since they are so comprehensive, I won't complain beyond acceptable norms.

This Old Tony, you're like my favorite shop teacher. Only with less cursing and more fingers.

ToT is probably the only KZfaqr who can have 6 minutes of talking at the start of a video and I don't even notice. When he said we were 6 minutes in I had to check the time. 😂👌

I've watched This Old Tony for over 2 yrs now. I don't do any of the things he shows in his videos or even own the tools he uses, at least not many of them. But I just love the videos he creates. The concepts and creative way he goes about explaining things, I really appreciate. I wonder how many others like myself subscribe to Tony just for his style and to pick up what things they can while they are entertained.

I have literally never touched a machinist's lathe or a mill. And yet, I have watched every ToT video. Even if I never do any machinist work, I think ToT is worth watching as a lesson on how to teach others. His videos are entertaining, engaging, whimsical, and generously educational. Thanks ToT, for another mind blowing video and for using your educational gifts to help set the standard for KZfaq artisanal videos.

Working in aerospace on CNC mills, we used carbide helical thread mills that looked similar to an end mill with threaded flutes and would helical interpolate them inside a large boss to create threads. A massive improvement over the massive taps we originally used that generated enough heat to warm your home in winter.

I really hope this one holds up to the standard you set during the last threading video. The use of colored smoke in your signals really changed things up!

My serotonin spiked when I saw the ToT logo pop up in my notifications.

If you braze the tap into the center of a piece of hex stock for a 3 flute, or square stock for a 2/4 flute, you can use all the flutes as cutting edges over time and still use them as a standard tap.

Anyone else been watching this 4 part series since the beginning? Back then we were trying to cut threads into rocks with other rocks.

I kept waiting for the reveal on whatever special effect was used to generate that comedically large nut and bolt... but it appears Tony actually had that on his bench, in case he needs to mount a 5-inch deck gun to his dirt bike.

My friend is on lockdown at the moment and can’t leave his house. We call him Internal Fred.

@This Old Tony. You're a master machinist and a master presenter. What's more, your hands speak to me! Thank you for your great inspiring videos.

An "old" trick. I learned it back in 1970 when I went to work as a machine operator. Great for cutting fine threads in large diameter bodies. Company I worked for made hydraulic cylinders for aircraft. We used this trick to cut threads into cylinder bodies so gland rings could be screwed in.

This is life changing 🙏🏼⚡️🙏🏼

Just have one thing to say we need more this old tony makes my day when I see there a new upload to watch from the UK please keep them coming nice to see someone that teaches and entertains to well ...

Thanks Tony, with this video I was able to make a part that I couldn't buy. My son salvaged a chinese lathe from the scrap metal bin at his work. It had some problems but since we had it for free I thought I'd have a go. I'm a 60yo novice to machining with my own cheap lathe to work with. Anyway, the biggest hurdle was the spindle pulley nut was missing and I couldn't find a new one. It has a 28 x 1mm inside thread and I don't have the right tools. I do have thread taps though. Long story short, made the part successfully from 12mm steel plate and a home-made tap holder with set screws. From a novice, this is my proudest achievement so far. Thanks again for your advice and encouragement. Love your channel and your style, cheers.

"If you're a masochist, I mean, machinist" that gave me a good chuckle

That's a very useful trick. Setting the tap at a fixed angle to cut tapered threads is genius on top of this. It seems like you might be able to use the same tap on the backside to cut a left-handed thread too?

I always thought you can only internal threads into stuff, but apperantly it is possible to cut external threads into stuff. Now i am no longer stuck to cutting external threads exto stuff! Thanks alot.

Hi Tony. Great video again! I've used this technique 'the other way around' - with the workpiece stationary and the tap spinning (CNC). It means different sized threaded holes can be machined with the same tap - obv. same pitch thus reducing tool changes! Also if an angle is ground on the 'leading edge' of the tap, similar to a drill bit, the hole can be bored first, then tapped. I believe this is called a 'thriller' (tap and drill-er)

I missed the first two episodes of this series but saw the 3rd episode and I have to say that the quality of your videos has improved significantly since then! Can’t wait for episode 5!

Wow, the first new way to break a tap in over 2 millenia!

Auto shop guys: "Don't look at that tap the wrong way" Grey beard machinists: "Hold my Dykem remover"

Excellent tip, it still amazes me how something can seem so obvious

This is honestly the first time I have learned anything from watching literally thousands of hours of machining videos. Well done sir, well done indeed.

I just wanna say, the humor, the presentation, the information, it's just so perfect! Thank you so much for the hours of joy you have brought to me, This Old Tony!

Disappointed with the lack of demonstration for the manliest method of cutting threads - cutting a single groove along the long axis of the work, and then twisting the work to make a thread.

As someone in sales working with machinists, this video really helps me to understand the mindset of those guys. Thank you very much.

I don't know what's more captivating - the tips & techniques or the dry sense of humour ! Love it. My life have been changed watching this....

I really enjoyed the other episodes. The "Turning shale with granite inserts" tip was great.

Being a teacher for 30 years, I don't know how to assess the quality of your work. My scale has a maximum of A +. You deserve more. Thank you for the intellectual pleasure you give us.

This clip is not quite the info I was looking for, but I was so intrigued with your media and dialogue skills/quips - I was compelled to watch all the way to completion. Your engineering skills too are high level and a match to your filming, which in my view is worthy of a KZfaq Academy Award- if there was such a thing! Thank you for posting....

My dearest Tony , i am a construction worker, so everything you show is Magic to me . I Love your Videos

I’m just impressed you’re doing in-camera time stamp callouts. Flawless production.

I'll add this to my "you can also use a small end mill for a boring bar" bag of tricks.

I'm glad you clarified the person vs hole minimum size issue, I was confused for a few seconds.

Hi Tony, I recently found your channel and have gone back in time and watched every video you have made so far. I hope to watch the ones that you have already made in the future some day! Not all of us can move as freely through time as you can. Really love your sense of humor and amazing skill set. I recently acquired my second lathe and my first knee mill and have been going crazy buying tooling and trying to get it all up and running. I would love to send you some photos of my setup sometime.

I really enjoy these “hands on” videos 😊 And yea n case folks are wondering, a 1” x 24 tpi tap is about $40.

And how am I supposed to get the tap stuck in there and subsequently break it? Huh?

I am retired from 40 years in the manufacturing industry. in all those years I never thought about using this process. AWESOME dude! based on this one video, I think I am going to subscribe for a while and see what this old dog can learn from this young pup. :o) got my own retirement machine shop that I play in constantly. I blood is mostly cutting oil. thanks for the info. now I just have to find a project to use it on. :o) I luv your This Old Tony Picture. I am also a fan of Ron Covell.

Ever since the AcME- no Ac You! video, my life has been waiting in anticipation, for this day. Tony is a treasure.

The one trick that "Big Tap" doesn't want you to know.

9 out of 8 times I learn something from these videos.

Cool video Tony. This is something new for me to try when the time comes. I do a lot of threading on a lathe. One trick I have picked up is to use a combination of single point and a tap or die. Basically I’ll rough out the threads single point to about 90% finished, then chase the remainder with a die. This eliminates all of the tool pressure when cutting with a die and will give you perfectly clean threads to size (assuming the die is reputable and not import junk). It’s also great for internal threading, especially blind holes. Thanks for your videos!

Dude you are a legend. Thanks for your incredible sense of humor. I'm not am engineneer but I do learn a lot from your videos. Keep up the good work

Damn Tony, you're getting so insanely good at this. Love these ones, I mean I love them all. But these comedy ones, with editing. Your skills are on another level.

ToT, the fluff and dad jokes are why we all keep coming back. We love you

My Dad did this in his early life, I never understood what he was talking about? Thank you for making it simple to understand the complexity of a die and tool maker...

Your level of snark is right up my alley. Can't recall how I came across your channel; but am very glad I did!

Interesting use of a tap, or as you would say, faucet.

I have never clicked faster in my life. Love your vids. Keep em coming

Dude, I envy your talent for amking interesting, entertaining videos and your brilliant sense of humor. I really, REALLY enjoy watching your videos, not only for the interesting subjects you deal with, but also for your bone dry humor. Thank you, please keep at it!

If I was to teach metal working in high school or college your video's would be required outside material and quiz questions taken from them! Always educational and entertaining!

What a coincidence... I was just rewatching old TOT videos when this suddenly popped up

Love these tips videos. I'm sure it takes 2021 years to come up with each new tip series. Please don't feel like you have to show us something new though. I just love to watch you play. Would love to just watch a ToT live-stream of you cursing at your machinery.

Your delivery certainly makes me laugh what with your double entendres and play on words etc. I do enjoy watching your presentations plus i actually learn something. top marks!

I actually used this trick today! I would never have thought of that if I hadn't watched this video. Thanks Tony!

7:10 1"-24 tap: $20 on amazon. So... yeah, TOT, that sounds about right for your luck.

MY Favorite Threading episode so far..

I love how the style, editing and crazy script always make these videos on mundane things seem really interesting. 👍

As usual, I like first so I dont go all crazy binge watching TOT episodes I have seen 10 times. I do want a bumper sticker saying, "TOT taught me to weld". Love your stuff, very informative and entertaining. Got myself some machines, therefore now have more reason to watch all your videos over. Appreciate you Sharing your knowledge.

Great tip and I have a an entire new set of taps I was planning on breaking anyway.

WOOHOO! The best part of my week is finally here!!!!!

Dude I love your content. It's educational, entertaining, and humorous. I do plan on sticking around for another 2021 years for the next episode.

Brings back a memories of when I had to cut an internal left handed tapered hole for pipe threads with a taper attachment on the lathe. I probably could have used some of your tricks. Interestingly enough in the old Machinery Handbook the topic on threads occupies the most pages. Threads are a science in and of themselves that have always fascinated me. Whitworth, Acme, metric, microscope, etc. Then there is class of fit and shape. It goes on and on but basically the "thread" is one of the simplest basic machines "the inclined plane" shaped in a spiral. The geometry and math involved in threads is really interesting if one gets into it but basically there are 13 types of threads each with specific properties suited to particular machine applications.

It’s not even funny how fast I clicked on this video

Oh good, now I can continue using “I’d tap that” as my catch phrase and have a way out when someone calls my bluff. Ty TOT!

Damn it, I wish I'd seen your awesome tip a few months ago. I paid about A$90 for a 7/16 - 32 tap. Now I realise I could have used a basic 16 tpi UNC tap to cut the 32 tpi thread. I probably have a spare one sitting in my drawer. Thanks very much for this tip, won't forget it in a hurry.

Thanks for this. I have been doing it for years, but now feel, for the first time, that I can come out and admit to it.

And if you need it for a pitch you don't have a tap for, pick one that's close and grind all the teeth off on that side of the tap except one fully formed tooth

Cool! Some bicycles have 24TPI threads on the rear hub. Now I know one more way to cut that thread. Thank you, bless you and stay healthy!

Very useful for fine treads...and as usual, the way you teach is a lesson for any teacher...

For years, we had some jobs come in the shop that required a large bore (3-1/2”) with very fine (16 tpi) threads. Sometimes, those threads would get damaged in handling. I would take a bottom tap of the same thread pitch (3/8-16) and mount it in a file handle. I could then reach into the bore and carefully scrape any irregularities out of the internal threads. It worked out very well.

Leave it to TOT to make thread turning into a thrilling edge-of-seat video!!

Omg 15 seconds!! This is the fastest I’ve ever made it to a ToT video!! Sounds like a fun topic too. Believe it or not I am a big fan of your threading videos, dude!

Due to your humor, I'm giving you a digital hug and kiss. You're so cute. 😘

That's pretty cool I don't know that I would've thought of that. I can appreciate all the effort it takes for you to make the videos as well as you do. With the pandemic going on. I've had to make videos for my students and found that's a lot harder than one would think.

Last time I was this early, ToT still had fingernails.

I physically can't wait for the next thread video

Thank you - Your 6 minutes of fluff were exactly what I needed today.

I love that I know almost nothing about machining, never have had or plan to have an insane interest in it. But still I love Tony’s videos.

My prayers have been answered and on a Sunday what service!

"Under a certain size" Me a 2 meter tall dutchman: bamboozled Thanks you clarified after tho

So I found myself in one of those pinches everybody always warns you about, and I used this trick to make the threads in the collet side of a 5C draw bar for my little Atlas. This is a very useful capability to have in your repertoire.

Thanks a million Tony, another ingenious tip for manual guys to keep up our sleeves! Of course, I'll need to run it by Stefan first. :)

You unlock this door with the key of imagination. Beyond it is another dimension: a dimension of nerds, a dimension of craftsmen, a dimension of ToT followers. You’re moving into a land of both a voice and this voices hands doing.. um.. stuff, of things and ideas. You’ve just crossed over into… the This old Tony Zone. Doo de do do doo de do do

That is a comically large bolt and nut, and I love it.

Another example of "Why didn't I think of that?!" This will save me some money and a lot of time on an upcoming project. Thanks TOT!

Man been waiting a long time for episode 4. Video quality has definitely improved in the past 2021 years! So looking forward to episode 5!

I think I can hear abom breathing heavy when he heard tony say large taps.

I would of never though of using a tap that way. Thanks Tony!

As a fun sized guy, I appreciate the distinction. I was about to throw all my taps out! Glad I kept watching...

I've used end mills as boring bars many times. Never thought to use a tap as a stationary hob. Thanks much for the tip and the humor. Thumbs up to crush a troll.
