This Bolt is Broken... I Make a New One! Machining Left-Hand Thread
Вставка
- Опубліковано 19 лип 2021
- In this video I'm making a custom bolt with a thread on each end. One of the thread is a regular M16 thread and the other one is a left-hand M16 thread. In the center there's a 24mm hexagon. This part is used to adjust the distance between two parts which are used for a foot pedal on a machine. As both threads are pretty big to cut with dies I decided to turn them on the lathe. I was lucky that I was able to loan both thread gauge rings from a local company. This made the thread turning to the correct size a lot easier. For rust protection I decided to do hot bluing on the bolt. On the two blue parts I only had to recut the threads.
I hope you like my work and the video.

Unfortunate your lathe bearing is near its end but you know it would make an interesting episode to replace…yes?
Indeed, but I think I probably won't. It works fine for normal use, so far ;-)
next restoration video - your lathe
My lathe is broken - I make a new one
@@mymechanicsinsights my method to deal with chatter on form cuts is to take the final pass turning the spindle by hand and feeding in tiny amounts. Works brilliantly. What lathe do you have? I'm not really surprised it chattered on a form cut like that in steel, don't worry about spindle bearings!
If the lathe is old there is probably a good chance that the bearings are adjustable.
If not bearings, it could be the chuck jaws are bell mouthed and need recutting.
YT: “My Mechanics Insights has released their latest video.”
Me: “I watch a new one!”
I hope you like it
Lol
* After wathcing the latest video *
Me: I watch old ones again!
Wonderful to see such a wonderfull long video on a "single part", and see all the details that go into making it!
Thanks Hans, I'm glad you like it.
A real insights video ;-)
As a machinist i know and appreciate the work that goes in to every part that he "makes a new one"
The only man with an M16 left handed thread Guage ring
Actually there aren't left-handed M16 gauge rings for sale in the whole world. He made a new one.
No, he says he borrowed it from a local company :-)
@@ermannopinotti9922 Have one at my work... 😌
Woosh
Thanks for giving us some of that real-time view. And thanks for not making us watch all of it in real-time! :D
Yeah haha. It's a real shame that this lathe doesn't has a spindle brake. It takes ages for one pass with those slow rpm's.
Next video: making a spindle brake for my lathe
@@mymechanicsinsights couldn't you have done it faster on the left hand thread, since you didn't have to worry about running into the hex?
@@anqied when i run backwards i have the same problem
@@PointlessMiracle thought about that already
"Lathe is old and chatty. I am neither. I make a new one!"

Greetings from St. Petersburg!
You said: "I hope you like my work and the video."
You don't have to hope, you MUST KNOW that your work evokes the most positive emotions in normal people. Your videos can help normalize blood pressure and reduce fatigue and aggressiveness. And whoever does not agree with this - let him go to hell.
Fully agree. Greetings from South America.

@@andrepaio7751 Hi, Andre!
Oh, St. Petersburg, I'm laughing here in Wisconsin!
I just know THIS kind of craftsmanship is gonna' get me into Divorce Court! This gentleman's skill has inspired me to buy that lathe I've been fanaticizing about for eons! Thanks a LOT, sir!
by the way, not only your craftsmanship is on another level but also your video-editing skills are awesome
This guy is so skilled it's almost offensive 😄
I was offended. Time to tweet about it

As a person who knows nothing about engineering, that was amazing , thanks 🙏🏻
Next up on MyMechanics:
MyMechanics lathe is getting worn out, watch him make a new one with not one 90 degree corner anywhere in sight and so shiny that it must be kept in a Vandablack room at all times else it blind the entire population of Switzerland and rase global temperatures by 5C. This whole process will take 6 hours and be condensed down to a single 30 minute video astonishing all and making all other UA-camrs gnash their teeth with jealousy.
This is the first time I see a sketch well done, as a teacher this makes me happy
By the way, since you said your lathe is getting old, do you think you could get a sponsorship for a shiny new lathe on your main channel? You've got almost 2.5 million subs now so maybe it is possible, certainly you wouldn't be the first engineering channel on youtube to get given extremely expensive shiny new tools by sponsors.
That would be amazing
Unless you have a lott of Money, new lathes don't compare to the quality of old ones
Or at least maybe something from Scotch Brite :)
@@mymechanicsinsights hopefully this is not a realistic option for you, please do not replace it with a new one. This old machines have a heart and worth to earn the love and maintenance they need to keep on going ❤️
@@rexaitken exactly, the new ones are usually crap, and if they aren't the price tag would give you a heart attack
Whatever you do your fastidiousness and painstaking make your work perfect and interesting.
I like your work so much
I feel like this is the first time I've seen you do something that you would actually do in your regular day-job as a machinist, remaking custom parts for machines that need them (I'm guessing you don't repair a lot of coffee grinders at work...or hey actually maybe you do, I honestly don't know a whole lot about machining)
Is there a video of you explain your "story"? How it all started, what you did for living earlier/did you learn this stuff or did you teach it by yourself? Your skill range is just crazy !
Can’t wait to see the new video on the insights channel. Opening line my lathe is broken, “I make a new one.” Love seeing the whole process in making something that most people wouldn’t think a second thought about. 👍👍👍
LOL'ed at the Patrons name Pong Lenis.... True Gold.
You are the best! My wife and I celebrate your videos.
I’ve been following your main channel since ~10k subscribers, and your content still continues to amaze me. Perfection!
Nice to hear that, thanks a lot
Can't wait till you make a new lathe.
Seriously though, watching you make a bolt is better and more entertaining than most of the videos on UA-cam. 👍
Amazing that a 60 year old lathe is still that accurate. Weiler should be proud. Everything you do is a work of art and this turnbuckle bolt is no exception. It’s beautiful!
Hiii my mechanic. I'm from India, Kerala
I hit 'like' the moment you started sketching. So great to see the whole process! Well done that man.
I never knew watching a bolt being made could be so fun. This was a great episode!
What a great video. I was about to close my laptop and noticed your video. Good reason to relax and enjoy for 13 minutes. Perfect end of the day for me here in Malaysia
Lathe restoration video, please :)
It's 1251am here and I'm watching someone make a bolt. BUT I'M LOVING IT
The Mozartean clarity of this creation belies its stunning beauty. This is pragmatic art of the highest level. No moving parts -- and yet, for me, this special bolt is a minor masterpiece. Bravo!
Until you wrote it, I had been searching for the right adjective to describe MM's work. Mozartean it is! Thank you for putting your finger on the right word--and for writing such an elegant description.
Absolutely.
Awesome video! Would love to see more of these indepth "I make a new one" regarding specific parts!!
My dad was an enginner in the cold war days working on cutting edge defense stuff. He tells a story of the best mechanical engineer he ever worked with going on a boating trip in the Caribbean and his engine failing. He collected some broken parts and headed into town, found a machine shop, and took it over to make his own replacement parts. Problem solved.
I'd love to be able to show him this channel and say "is this they guy?" :-)
I could watch machine work for hours.
12 minutes and 54 seconds of pure satisfaction!
Hi Mr. Mechanics! I really appreciate that you made this video showing your "method", from sketch to final test. In a complete restoration video you make is seems so quick and easy, and I think it's one of the things that amazes me. And a 60yo lathe? Wow! Have you ever showed it and the whole workshop? I've really like to see it. This video proofs how very much talented you are. Kudos from your big fan from Brazil 💜
Applause for the artist!!!👌👌👌👌👌
Your hot bluing is always lovely. It looks better than anyone else's that I watch.
The best part for me of your restoration video's is when you use the lathe and milling machine. You should do more videos of just making parts on them. It would also be interesting to know what metal you're using when you make a part. Example, are you using 4140 steel?
You really do beautiful work, especially on that 60 YO lathe.
My favorite 5 words in the world! "I make a new one"!!!
Gut, dass wir CNC Maschinen haben, aber konventionell Fräsen und Drehen ist einfach das beste! Ich liebe es :)
Would you have thought, only a few times ago, that filming yourself machining a screw on a lathe could achieve 100,000 views in 1 day? I will be curious to know how many people who are not at all from the industrial sector you have been able to attract there thanks to your high quality restorations ... especially nowadays in this world where everything is only computer, digital, virtual, easy, fast...
It is a pleasure to see you mastering the techniques of drawing (respect for the thread symbol), machining, dimensional control (a no-go threaded gauge? no need, thanks ;)
For your lathe, a French proverb says: "it is in old pots that we make the best soups": keep it as much as possible!
If we weren't so far away, I would give you with pleasure some nice pieces to restore that I haven't seen on video yet.
Cordiales salutations my friend and long live to the famous Swiss precision!
🔥🔥🔥
hi mr tysy i love ur videos
la démonstration à la fin est bluffante!
terribles vidéos aussi TysyTube!
Why do you paint rust/dirt in your videos? I can not watch, it makes my face pucker.
It's really heartwarming and oddly satisfying ❣️😊
I think this bolt looks better than the one your friend had in original. And will last for sure longer. Thumbs up. 👏👏👍
I would love a video about your workshop cleaning routine - particularly how you collect all the metal shards!
With a vacuum cleaner :-)
@@mymechanicsinsights 😃
To stop chatter PLACE A BIT of wood above the work piece on the outside dia. But if you have already chatter remove it by stopping the spindle and dig into the chatter manually by rotating the spindle a few turns by hand .
Will the next restoration project be your 60-year old lathe? This would be a nice saga.
I have worked on and rebuilt many older manual lathes,some from the 1940s, as far as the chatter goes (start with simple cheap solutions,work up to expensive ones), the first thing I would check is the cross slide gib,it may seem tight but even if there's a little play in it,when you start your cut it can drop the cutting edge of your tool below center causing chatter.
I would also check the same on the carriage,it's always good to check the play on all the moving parts with gibs in them at least on a yearly basis.
Great advise!! I'll check that, thanks
@@mymechanicsinsights Hopefully it's not your spindle bearings, bearings are fairly cheap but replacing them can be a pain in the rear sometimes.
I have watched many (if not all) of your videos and know chatter has not been an issue before that I have seen so it kinda gives you a clue that something is worn or has just moved out of tolerance.
Although a spindle brake comes in handy, with older machines it's just not worth the cost in my opinion.
If it is a spindle bearing issue I would first check your endplay and runout,maybe it's something as simple as the lock-nut being a little loose.
I know I seem to be going on over something as simple as chatter but with a machine that's almost 60 years old it could be something that needs attention now before it gets worse.
First i watched this video on Facebook now watching again on UA-cam. Your work is so satisfying dude😍
Always wondered how you cut threads on a lathe, can you do a video explaining the system please?
Thanks 👍
Dammit, I thought you just eyeballed everything. 😄
lol
If only I had the skill set like you,, I admire your work!!
You sir are an absolute Master of your craft. I have nothing but the utmost respect for you and your skills. Thank you so very much for sharing your expertise with all of us on UA-cam. It always makes me happy to watch you work your "magic". Fred
A new video. Today is going to be a good day.
Lathe doesn't work. I make a new one.
Yeah too bad. I've had a similar issue before when parting off tough steel. It doesn't really like those big radial cutting forces.
A nice and unexpected balm for a Tuesday morning. Thank you!
Time to make a video of you replacing the lathe spindle bearings... Great work.
I like your clean hands. People who do such amazing things usually have black dirty hands.
Nothing wrong with dirty working hands.
Lmao...
Yeah, cause most of us are focused on getting work done and not keeping our hands clean for a UA-cam video...
Good grief.
lol, absolutely true. mine are dirty off camera too
@@mymechanicsinsights someone appreciates the lengths you go through to have clean hands during a video haha
Me, watching you checking the M16 right-hand thread with a standard gauge ring: Ah, indeed, but how will you check the left-hand thread? It's not like you'd have a left-hand one just lying around.
Me, watching you checking the M16 left-hand thread: Oh. Well, that was silly of me to think that!
(Me later: I suppose I should have read the full description!)
;-)
This simple bolt once again shows that really great engineering is indistinguishable from art.
I love the way you restore tools .
Time to work on yours.
You take care of tools - that'll take care of you .

Should you be quenching in a glass container? Wouldn't the temperatures break the glass?
I worried about that. Maybe it's borosilicate glass? Very resistant to thermal stress.
Well, you saw that it didn't break ;-)
It's just normal glass
The amount of oil is enough that the temperature of the part will dissipate all its heat energy long before the glass can get any significant amount of heat applied to it. No risk of it breaking with what he is doing.
He's only heating it to like 600F to turn it black. Which doesn't require quenching at all. To harden steel you have to get up to 1400F and then quench it fast. And when you quench hardened steel, you need a LOT more oil than he is using. This is only for show. All he did was make the part oily. Beautiful machining, but this part is just nonsense.
@@AcmeRestorations You need oil to make the bluing stick. Otherwise it will peel off.
The compressed air clearing away all the shavings has become my new favorite thing in these videos🤩
Outstanding work, as always. It's a pleasure to watch you work.
I think your chatter issue is purely down to the fact that the HSS cutter is trying to cut on three faces at the same time, and is binding, as you move further into the work. If you had some relief, either on the work piece or the tool, or used a smaller round nose cutter to created the valley in multiple passes, it would eliminate the binding/chatter.
It has relief on all sides, it was just too big and the lathe too much wear.
I'm surprised that you already had an M16 left hand thread guage in your equipment drawer. Lovely job.
What steel did you use for this part?
What was the broken system for? It looks agricultural.
I borrowed the gauges from a local company. I used ETG100. It was some kind of a press or metal shear.
@@mymechanicsinsights i wish I had access to a small set, so useful.
a set of thread gage wires would be just as good to get perfect size threads. it isn't rocket science
Very nice remake. Curious... Did you make the thread gauge rings or were those shop bought? They look like they'd make a nice practice project for turning threads and knurling.
The gauge rings are borrowed from a local machining company. They are super accurate, hardened and its thread is surface grinded.
@@mymechanicsinsights AKA super expensive.
You cant really make a thread gauge with just a lathe....
@@mymechanicsinsights I can't figure out how you would surface grind an internal thread like that... Any insight?
@@Tombsar you don’t. We make them at work all the time. Rough turned in annealed material, then hard turned after heat treat to spec. There’s no reason to grind a thread gauge for average tolerance threads. There’s some super special grinding equipment for doing very tight tolerance gauges but it’s definitely not a surface grinder…. They are mostly CNC tool and gauge grinders made for that specific purpose. But yes. You can absolutely make standard gauges on a lathe, even a clapped out manual lathe if you know what you’re doing.
I absolutely love your channel. You are so so skilled at what you do. I love to watch you work
Hello my mechanics very pleasant to watch the video beautiful job well done my friend
I would have just welded the heads of a lh and rh pair of bolts together.
"I bodge a new one" lmao, i'd have probably done the same in the intrest of time
But it wouldn't be as interesting to watch :D
You just destroyed the video man!😂😂😂
It sucks to have to work on everything you own before you can use it, because it was "fixed" the "save time and money way". Like my dad does. It neither saves time or money.
It must be a good friend with all this work. What's her name?
🤣 lol
I really appreciate the extra commentary on why and how you are doing each step, very informative Thanks
Always a pleasure to watch your videos, congratulations on the work. Greetings from Brazil
Are we going to get to watch you restore the 60 year old Lathe?
Yes please!
If someone like Abomb or This Old Tony was making that they'd probably use a 4 jaw chuck, it always seemed like a massive pain to me but apparently the reason being that 3 jaws don't always centre properly, so when you flip the piece over the two ends might not perfectly align. This obviously seemed to come out fine, but would you use a 4 jaw if tolerances were really tight?
3 jaws are running true in around 0.3mm max. But you can always center it perfectly with a few light hits with the nylon hammer and dial indicator. I think the 4 jaw is an american thing. I have never seen anyone in real life clamping a normal round part in a four jaw, only on youtube.
@@mymechanicsinsights Interesting, thanks!
My dad made me learn on a 4 jaw chuck. What a pain in the azz. Yes i am in america. If dad was still alive i know he would love this channel.
If you want to eliminate/reduce chatter, use a chain or spring wrapped around the work piece. We do this in automotive when we resurface brake rotors, my shop has a 50+ year old brake lathe that has the same principles as a regular lathe.
Very good. I found it interesting that the lathe only chattered while doing that particular part.
There's something so endearing about seeing someone whose work I admire dealing with the same issues I do in my home shop. You're wonderful at what you do and I'm personally offended (haha) that your lathe wants to stand in your way.
Gorgeous, quality work as per usual! I am pleased that so many people appreciate your philosophy and attitudes. Simple machinery can be beautiful
Thank you very much!
Really loved this super "insight" project, showing how much time and dedition cost every single piece. Great job mymechanics!!
I would love to see this with even more details. I'm fascinated by how accurate you can be with your tools.
a friend hands you a broken bolt you give him a work of art back! gorgeously done!
good job
Make threads is one the coolers things to do, i have a lot of fun
That's 'just a bolt'. Yet it took a skilled mechanic probably two hours to make. This is why I treat my tools, fasteners and machines with care and respect. And I like to think they respond in kind, and last longer and give me a chance before they break.
Those are beautiful thread gauge rings 😃
Great video. Love the paper diagram showing all that's needed to get to the point of "I make a new one." love to see more of that. Really behind the scene/what's in your head when designing.
You gotta love how tools appear without the hand holding them on screen making the tools look alive and working, measuring etc by themselves
Fantastic video, much of what is demonstrated here is used almost daily in the hydraulic repair shop that I work in.
This might be a little presumptuous of me, but in my opinion you are the most skilled person at this of anyone I have seen. I can't get enough of your videos. You have such care for your art.
Stunningly beautiful bolt! Lucky friend!
It is still amazing and satisfying to watch a piece of metal turned on a lathe and made into something useful. I worked in a machine shop in high school sweeping the floors, I’ve seen first hand the time and the knowledge that goes into this kind of work. Thank you for sharing your skill with us.
Very nice work with and old lathe. As an engineer I enjoyed watching a great job!
Thank you for sharing your gift with us. I've only recently become fascinated with machine tools and the machinist's art, and your videos only heighten my appreciation. Thanks again from an admirer in the US
First off congrats on 300k subscribers and secondly, its always nice to see your videos.
I can watch all day making new ones!
Using a form tool with a big radius is always prone to chatter. Reduce the stick out length as much as possible and use the lowest spindle speed available and lubricate well using e.g. Motorex cutting oil. If this doesn't do the trick remove the final chips by rotating the chuck by hand using the chuck key as a drive dog. This is how I do it and end up with good results most of the time. The condition of your spindle bearings (and quality/rigidity of the lathe to begin with) is of course really important. Maintenance could be complicated depending on the construction of your lathe and the availability (and price) of replacement bearings. But if the machine is worth it, and you proceed, you will regret you didn't do it earlier. It will put a smile on your face! Thank you for sharing! Best, Job
