- Using a tap to cut threads?! I know, crazy, right? But just you watch!
In a pinch you can use a smaller tap of the right pitch to thread larger bores than the tap was intended for. - Věda a technologie
After all those years he still amazes us all with yet another way to break a tap, incredible.
At least it won't get stuck
@@Lucas12v That's a feature.
@@Lucas12v knowing my luck, it would still get stuck.
Hahahaha.. right?!..

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.
That cursed obsidian used to sharer at every other threading...
@@666aron Look at you Mr I live near a volcano obsidian user, some of us had to make do with knapping pieces of flint
Tell me about it! I never got the hang of tempering hardened bone tools... But it didn't matter, I'd barely mastered the inclined plane back then, I wouldn't have dreamt of wrapping one around a shaft!
Sounds like you made a classic rookie mistake. Always cut the threads before firing the clay.
Potter's wheels were the most common lathe when episode one premiered.
It was actually easier, the threads just weren't nearly as strong... or useful.
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.
Is that the inverted thread made from a tap extruded from unobtainium…..
@@gfenwick1 Heck I didn't think of that, I've been hand weaving mine using carbon nanotubes. Kind of hard on the eyesight.
But you need to remember to cut it as a left hand thread so it's the right way once you turn it inside out.
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?
I am jealous dude I love learning from old timers I am a journeyman tool and die maker because of a man like that
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'm not a machinist, but I grew up around them and caught myself laughing at his hidden jokes. I enjoy his style and sense of humor and great editing. He's a CZcams gem.
Same lol. Never ever even touched a lathe. Only ever did minor woodworking with my dad. I don’t even aspire to be a machinist (sorry). These videos are the best, just so entertaining, funny, informative, and relaxing to watch.
Yip. That sounds like me.
I have never seen a lathe or a milling machine in my life and I love watching Tony.
@spic mix that was exactly the second video I saw of him! First was (funny enough) the first one about threads because I was curious about how to do screws. Four years, almost five later and still here.
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.
Awesome
And you keep up making new inventions! :)
This Young Tony (someone would make it anyway... don't blame me... blame the game)
Awesome. I'm 15 and started machining when I was 14 and I love it. I already have lathe, Tig welder and some tools my dad gave me. I'm also getting milling machine soon. You will be definitely good machinist. 👍
Nice one mate
This Old Tony, you're like my favorite shop teacher. Only with less cursing and more fingers.
is AvE the teacher with more cussing and more fingers?
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.
speak up a bit I started loosing my hearing about a thousand years ago
ToT is probably the only CZcamsr 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. 😂👌
And when he says he's just gonna shut up and get done I'm like .... noooo ... keep on going! I don't want the video to end!
Oh good, I thought I was the only one - - -
@@technik27 you've got to be kidding, he talks way too much rather than doing some work and his lame attempts at stupid jokes are just the most annoying part of his videos and it's the same in every video.
@@jamesadams893 If you don't like ToT's jokes, and you don't like his talking... maybe this isn't the channel for you man. Unless you're really fond of his hands. But hey, you do you.
laughs in nutnfancy 😂
It's been a long 2021 years. Glad we made it to the next one though.
Have you really seen the previous one 😁
Can't wait for 4042 for part 5!
I'm still sanding my tool from the last episode.....
Guys tell me what happened part 2 and 3. Couldn't watch them had to work on the pyramids at part two had a really tight time frame back then. At part 3 there was some guy born and the emporer went nuts back then so no watching tot either
Parts 2 & 3 didn't really live up to my expectations tbh, I'm still using my original bone threading tools, they where the real game changer.
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 CZcams artisanal videos.
I often fall asleep to his ramblings
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.
That's kinda like cheating ya know
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!
If you had the new immersive headset like I do, you'd have known that was also flavored smoke. Although not delicious, it was informative and I will definitely be more choosey about which videos I watch going forward.
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.
Niceeeeee!
I actually used this trick today! I would never have thought of that if I hadn't watched this video. Thanks Tony!
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.
The city leaves those things all over the place under every street light... Just go grab one if ya need it!
I carry a few of those in my pocket for emerg situations.
You laugh about that nut, but the reality is that Tony is just very, very small.
My dad engineered power plants and would occasionally send me photos of flange bolts 4X that size which had been ripped apart as if by the hand of an angry torque god. The one you're talking about is barely larger than what you can get at the hardware store. Certainly Fastenal would have them in stock.
@@csn583 Yeah, the fasteners you see on cranes are insane. That latest crane collapse showed evidence of those massive things sheering right in half.
My friend is on lockdown at the moment and can’t leave his house. We call him Internal Fred.
Boooo
hssssssssss
Nerd!
Haha!
Mucho giggles... 🤣
Anyone else been watching this 4 part series since the beginning? Back then we were trying to cut threads into rocks with other rocks.
Shockingly, I think we had bronze back then.
@@gamemeister27 T-Rex toenails were the carbide of the day!
I watched the first 2, was following along, but then I lost the thread.
Good old times dude, sadly the Pangea separated US... I miss u dude
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....
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.
That's a genius suggestion - if you got some clay and spray painted it metal silver you could pull this on camera I reckon! ToT could do some video trickery like that for sure!
Three grooves for a multistart !! 🤗
Rubber Gloves and metal softener spray helps tremendously.
Ha that’s awesome. I saw someone online who made a replica cannon and had to do that to do that for the rifling of the barrel.
Getting it to twist consistently is a huge challenge with this setup. But manly indeed
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 ...
"If you're a masochist, I mean, machinist" that gave me a good chuckle
I mean, he's not exactly wrong...
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.
Improvise, adapt and overcome.
You made it work Sir, good job.
Play stimulates creativity, and vice versa.
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.
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.
I’m just impressed you’re doing in-camera time stamp callouts. Flawless production.
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.
Is that the company that make the Concord landing gear train?? ;)
@@skf3747 Company was "Conair Inc." in Burbank,CA. We made stuff for a lot of different aircraft manufacturers. Landing gear trunnions for 727,737,747, DC-10, and L-1011 aircraft to name a few. We also made the canard actuators for the B-1A. Company went out of business when the peanut farmer elected in '76 shutdown numerous military contracts and put 30,000 machinists out of work in the Southern California area.
just wanted to ask you whether I need to set up threading gears according to the calculations you shown.
@@80gourav Yes.... You still need to set the gears to the pitch you are cutting. Also, on the parts we made there was a large "O" ring groove cut at the bottom of the threaded area. This served 2 purposes, 1.- A groove for a sealing "O" ring, and 2.- A relief for the threading tool to run into. Remember, the threading tool has multiple cutting surfaces.....it's not like a single point tool where you can just stop feeding the tool. You must make sure all the taps cutting surfaces are into the groove before stopping the feed. We modified bottom taps for this specialized purpose. Most had only 3-5 cutting surfaces depending on pitch.
Auto shop guys: "Don't look at that tap the wrong way"
Grey beard machinists: "Hold my Dykem remover"
"That's the grey beards' business, not ours..."
AHH HAHHAHA! What if your both?!
@@RinksRides Then life is really sweet!
i broke 6 taps too many hahaha
Thats 'cos auto shop guys buy their taps in an Auto Shop ... us machinists go to Engineering supply houses & buy quality non carbon-steel HSS taps... 😏
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 dont think so because the tap doesn't have the proper clearance and relief to cut the other way. But you might be able to get away with it on a verey fine thread. Good thought though.
I think that's the next episode, so we'll have to wait until 4042.
I don't think so because the tap doesn't have the proper Clearance and relief to cut the other way. But you might be able to get away with it on a verry fine thread.
@@coopermccom2316 If the clearance is enough for its original size, it's definitely enough for *larger* diameters.
I am thinking that maybe you are saying bring the tap in and then cut from the back out like how circular polarized light reflects, flipping the polarization? Maybe you are on to something. Except if the flutes have a slight angle (in the opposite direction you want), that might bind up as it cuts into the metal and make a sloppy thread.
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 CZcams Academy Award- if there was such a thing! Thank you for posting....
@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.
I'll add this to my "you can also use a small end mill for a boring bar" bag of tricks.
Thanks for the tip.
Wow - a heart from ToT... I think I pee'd a little.
@@leeroyholloway4277 🤣🤣🤣👍😎
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!
Almost did not make it through the fluff... but I had confidence Old Tony would get to the point
, and he did ....... finally. Thanks, I had not seen this presented before.
My dearest Tony , i am a construction worker, so everything you show is Magic to me . I Love your Videos
Wow, the first new way to break a tap in over 2 millenia!
And how am I supposed to get the tap stuck in there and subsequently break it? Huh?
This is a more elegant solution. With this, you can actually break it without getting it stuck.
I'm not sure, but all of us here have faith in you.
If you are like me you will accidentally find a way. Lol
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!
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...
I really enjoyed the other episodes. The "Turning shale with granite inserts" tip was great.
The one trick that "Big Tap" doesn't want you to know.
Underrated!
@@DSSlocksmiths Thanks!
Shhhhhh
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.
As someone in sales working with machinists, this video really helps me to understand the mindset of those guys. Thank you very much.
9 out of 8 times I learn something from these videos.
lol, aaand it's funny again!
Interesting use of a tap, or as you would say, faucet.
Excellent tip, it still amazes me how something can seem so obvious
I wouldn't worry, it only SEEMS obvious because it's being presented to look that way. A tap is absolutely NOT suitable as a tooling insert, the same way a bicycle tyre isn't rated for Mach 4. Yes it's the same principle, but a WILDLY different scale. Saw the handle off a tap and try actually milling with it. It won't be pretty, but it's as graphic a demonstration as I can think of to illustrate the problem.
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.
MY Favorite Threading episode so far..
Idk, episode 2 back in 2021 BCE was pretty damn good.
Are not all threading videos equally loved? Lol
@@traitorouskin7492 This one was a tap above the rest.
This is life changing 🙏🏼⚡️🙏🏼

Why doesn't everyone know about this Jimmy?
If Diresta is saying so is because it is indeed!
I'm glad you clarified the person vs hole minimum size issue, I was confused for a few seconds.
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.
I really enjoy these “hands on” videos 😊
And yea n case folks are wondering, a 1” x 24 tpi tap is about $40.
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)
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!
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 have never clicked faster in my life. Love your vids. Keep em coming
What a coincidence... I was just rewatching old TOT videos when this suddenly popped up
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.
The brilliance of this channel cannot be overstated. 👍
It’s not even funny how fast I clicked on this video

I laughed. Was funny.
7:10 1"-24 tap: $20 on amazon. So... yeah, TOT, that sounds about right for your luck.
Yeah, but you'd have to wait two, sometimes three days for it.
@@UncleKennysPlace And odds are you'll break it off the first time you use it anyway.
$63.35 from Travers. That $20 tap may not be up to the job for harder materials. But brass rings? Bring it on.
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.
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.
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!
That sounds like a really practical and reliable method.
Nice Idea. No measuring for the final pass and since it's a multi point cutter a smoother finish.
I did this this week as I needed 1/2-13 on 4130 for almost a foot I thought about a bearing rest to keep the deflection out but got lazy and after both "firm ends" were in tolerance I ran a die over the length and it worked well not as nice as I wanted but single point over a foot is a lot of flex
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.
Ever since the AcME- no Ac You! video, my life has been waiting in anticipation, for this day. Tony is a treasure.
Leave it to TOT to make thread turning into a thrilling edge-of-seat video!!
ToT, the fluff and dad jokes are why we all keep coming back. We love you
I love how the style, editing and crazy script always make these videos on mundane things seem really interesting. 👍
Your level of snark is right up my alley. Can't recall how I came across your channel; but am very glad I did!
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!

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!
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!
WOOHOO! The best part of my week is finally here!!!!!
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
Interesting.
Pick one that's a little coarser so the lone tooth is long enough. I once used a 1/4-20 tap this way to make 17/64-26 BSC nuts. It was very spindly as I had to relieve it a lot to fit, so it wasn't an ideal choice but what I had handy.
Out. Freaking. Standing.
Excellent demonstration!
My shop teacher showed me this WAY back in '85....
Of course, Mr. Sandusky also demonstrated the effects of a shorted Chevy HEI ignition on the ear lobes of people who don't pay attention.....
I've never forgotten forgotten forgotten either....forgotten, uh.... forgotten...
I like pudding.....
Don’t know how I missed this two years ago. Glad I found it now, I think I might be unavailable for the next episode.
Great tip and I have a an entire new set of taps I was planning on breaking anyway.
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.
Very useful for fine treads...and as usual, the way you teach is a lesson for any teacher...
Due to your humor, I'm giving you a digital hug and kiss. You're so cute. 😘
Last time I was this early, ToT still had fingernails.

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.
That last tap trick made it all worth while listening to your babble :-) Fantastic idea.
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
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!
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.
Hi I'm a machinist of 35yrs exp, personally I grind from old endmills,
