Great video. You taught me something today. I don’t usually cut left hand threads but every now and then a job comes in that requires it. I use to have the threads turned for me but now I’m going to do them myself. Thanks
John, your cinematic skills are becoming impressive. You have developed a good eye for the best camera angles and shots. Your videos are always interesting and well planned. Thanks for all the good work you do teaching us better machining skills!
I bet if you uploaded from 2:55 to 3:11 you'd get over a million views no problem, great clip, I love it when people get excited about what they're doing
Because the blade bolt was left hand thread and the blade grass lifts were for a left side discharge deck this mower must be a pull behind or belly finish mower for a small farm type tractor? Most small engine lawn mowers are generally right hand discharge as small engines with vertical shafts generally rotate clockwise when viewed from the flywheel side. What I reckon I'm getting at is that a good farm equipment mechanic or an experienced small engine guy could have seen those blades and known the spindle bolt was LH thread.
i smashed the like button for ya buddy i like the way you work fast you know your shit no fuckin around n strait to the point great job explaining keep up the good work dude ! hello from the USA
I really appreciate that you show things as they are, i.e. very hard metal that doesn't behave well. I just started to do lathe work and learning to thread something has been a bear. I see I need to be more patient. How much of a cut do you take per pass? Is there a rule of thumb?
no playing issue for me, cept for some reason its not listed in the normal place, only from johns uploaded videos, not on my subs list, perhaps you got in a bit too early?
I wonder how successful your left hand thread turned out, as you did not mention in the set up the need to change the toolholder shim. When cutting a left hand thread it is necessary to change the shim for a negative shim or the helical angle will be incorrect. It causes a lot of confusion in industry that toolholder can be left or right hand approach but needs a different set up to cut a left hand thread.Having retired after 37 years in the tool supply industry, I was spending as much time explaining this at the end as I did at the beginning.Have a look on any of the major carbide manufacturers under threading and they will show a graph of which shim set up you should be using.
Hi John nice job on removing that stud like you say it doesn't often work out like that. Great when it does but don't know about sexual though. good job on the bolt
Hahah, a great video. "That was almost sexual" I'll say earns the best quote of the year award on TH-cam. That's also a very nice looking old lathe, Harrison something?
How did you do it removing the stud in a lathe i think you did not lock tha tail stock that is why its moving as the stud is coming out . is it possible to use an ordinary drill bit
hi, excuse my ignorance in this matter, from framing during processing, I do not perceive the angle of the triangular cutting edge, compared to the piece, or the plane of the carriage, is slightly negative or positive? I wanted to learn, for hobby modeling, thanks
Just watched this, and have to say, if you were working for any of my local engineering companies you would be shown the door for cutting a left hand thread wth a right hand tool bit as you have done here. Right hand tool bits are designed to cut to the left, and left hand tool bits are designed to cut to the right. The tool tips have different lead face relief angles, clearlyt visible if yo look at the tool insert tip through a compariror or good magnifying glass.
Torneiro fraco, alem de tirar a resistência do parafuso não deixando um raio no canto pra não quebrar, fez a rosca a exquerda em baixissima rotação, ai o acabamento é ppessimo
(From California) We speak a wierd form of English but.... Secondly, the economics of your time vs. demand seem out of proporation. Third, the investigation to discover left vs right requires detective skills. Fourth: Link to next video? Great job.

Exactly the job I need to do.
I knew I’d find it here.
Thanks so much, …outstanding!
Loved the way the broken bolt came out so cleanly, quite a rare thing. Best wishes to you, Debs and your Dad.
Great video. You taught me something today. I don’t usually cut left hand threads but every now and then a job comes in that requires it. I use to have the threads turned for me but now I’m going to do them myself. Thanks
The broken bolt removal was *a thing of beauty*
15:51 is an awesome close up of thread cutting!!
John, your cinematic skills are becoming impressive. You have developed a good eye for the best camera angles and shots. Your videos are always interesting and well planned. Thanks for all the good work you do teaching us better machining skills!
Thanks
Hi, I received my prize of a spill proof pot and brushes and the tools for my little lathe were a really kind and genrous gesture. thank you so much.
You are most welcome
Matthewhydraulic motors where to buy
That was excellent John, nice to get unscrewed once in a while during a Lathe project :)
At 3:15 - "...that was so nice!" It's been a long time since I have heard true joy in someone's voice.
Nice work on the left handed thread cutting and the bolt John. I will have start collecting all the old driveshaft bolts from work now! 👍
They are good quality steel
Thanks for that, much clearer now to make a left hand tap.
That bolt looks like an original bolt for that setup. Nice job as always!
Nice to get a break on a stud like that! Here's to getting through February without freezing too badly!
Just makes your day when thing like that happen . Good Job John.
Cheers Fred
I bet if you uploaded from 2:55 to 3:11 you'd get over a million views no problem, great clip, I love it when people get excited about what they're doing
I may just do that lol
Bloody Hell John, Ecstatic thats what that was, Lucky Bugger Keep up the good work.
I couldn't breathe I was laughing so hard, "almost sexual"!! The excitement in your voice was tremendous! Good health to you and your family!

That was great the way it came out. :)
Nice result modifying that bolt. :)
G'day John thanks for showing that much appreciated John
I am never that lucky, nice job M
Great video John, keep'um coming..

Broken studs dont often come out like that… like clock work :) keep up the good vids john!
Parabéns pela criatividade de aproveitar o corpo de um velho parafuso, pra fazer a rosca esquerda que estava precisando, ótima idéia!
Never heard a bloke so excited to see a bolt come out.
LMFAO -"That's all I've got so That's what I'm going to use"
Great fix John .. Thumbs up !!
thanks for sharing your time experiences and videos with us.
i smashed the like button for ya buddy i like the way you work fast you know your shit no fuckin around n strait to the point great job explaining keep up the good work dude ! hello from the USA
Nice video angles , much appreciated. regards from South Africa.
Very nice extraction there!
When that stub wound out, "That was almost sexual that!"
This needs to be on doubleboost merch!
Nice work and thank you
Nice vid hard to understand what your saying but I learned a lot thanks 👍😊
I love reusing head bolts they are tough as nails bro !!!

Dear sir, Thank you very much for sharing your knowledge. Stay with God!
You have the same brand welder i have and also used the IKEA metal drawer cabinets as well. I built a welding cart around one of those
Good welding equipment
Learn a lot from your video. Thanks !
The quote of the year for the TH-cam machinists! "That was almost sexual!" When that stub wound out, I couldn't have said it better!
All good clean fun
video kept stopping and starting john still a great video
no playing issue for me, cept for some reason its not listed in the normal place, only from johns uploaded videos, not on my subs list, perhaps you got in a bit too early?
i just buggered up my lathes saddle nut for the lead screw. was tempted to fabricate 1 but it seems a big job.
And a fine left handed thread it was. Nice fix.
Very nice repair!
Thanks for the video John, you should patent that withdrawal method, I shared a moment there with you and 33.714 others of course. lol

I will look further in to this
Thanks for commenting
Yet another interesting video to watch 👍
"That was almost sexual" an AVE worthy quip!
Oh dear me that was nice
I think he would agree with you
That was so damn sexy I had to play that back 3 times! Needed a smoke afterwards.
Dobra robota. Aż miło popatrzeć i się uczyć. Pozdrawiam
Im still enjoying this video :))
Fun to watch👍👍👍👍👍👍👏🏻
Bloody hell John, you do make me laugh mate...............long may it continue!!
Thank you sir. Thank you very much.
02:55 - The Moment you were waiting for.
We have a saying john... "The sun has to shine on a dog's ass sometimes!" Nice job!
Hi John nice job on removing that stud like you say it doesn't often work out like that. Great when it does but don't know about sexual though. good job on the bolt
CRIED LAUGHING "ALMOST SEXUAL" HAHAHA. Cheers Grinsh.
Thanks for watching
I love that accent. North of England?
Enjoyed the videocant believe you didnt say champion once
Hahah, a great video. "That was almost sexual" I'll say earns the best quote of the year award on TH-cam. That's also a very nice looking old lathe, Harrison something?
wow this is so amazing
did you do the lottery this week john. With that kind of luck , you should have .
Hi John. Great video as always. Was that a knerling tool you used to centre that bolt ?
Just the back of a tool holder
nice job!
How did you do it removing the stud in a lathe i think you did not lock tha tail stock that is why its moving as the stud is coming out . is it possible to use an ordinary drill bit
First 👍🏻timing is everything
Good craftsman
hi, excuse my ignorance in this matter, from framing during processing, I do not perceive the angle of the triangular cutting edge, compared to the piece, or the plane of the carriage, is slightly negative or positive?
I wanted to learn, for hobby modeling, thanks
I guees there shoould be key on the shaft to stop it rotatingrom the shaft, thats why the bolt was broken.
John I think the Video uploaded badly because some people are unable to watch it would it be possible to upload again
Just watched this, and have to say, if you were working for any of my local engineering companies you would be shown the door for cutting a left hand thread wth a right hand tool bit as you have done here. Right hand tool bits are designed to cut to the left, and left hand tool bits are designed to cut to the right. The tool tips have different lead face relief angles, clearlyt visible if yo look at the tool insert tip through a compariror or good magnifying glass.
EXCELENTE !!!!
HSS parting off tool, got any tips on how you would grind this shape onto the blank? Mine has broken right off.
You are wrong, to cut left-hand threads You need to set the compound at 29° and to the left, you have it set to the right which is wrong
Torneiro fraco, alem de tirar a resistência do parafuso não deixando um raio no canto pra não quebrar, fez a rosca a exquerda em baixissima rotação, ai o acabamento é ppessimo
Dam bro that did feel good dident it !!!
Great
So that was almost "ORGASMIC" huh? - Could that problem with the taper have been the problem with the collet chuck? - Nice finished bolt.
What's the next bit of machinery are you after for the garage?
a tardis would be handy, he has no space!
jusb1066 that's true!
almost sexual, i pissed my self laughing john.
(From California) We speak a wierd form of English but.... Secondly, the economics of your time vs. demand seem out of proporation. Third, the investigation to discover left vs right requires detective skills. Fourth: Link to next video? Great job.
can't watch something wrong!!! please reupload
Made my day as well. Laugh.
up half a minute, six viewers already...
Ideal that.. Bolt out of a bolt, eh?
Can I get your advice on DPF's? What is the best cleaner to use. Wynns??
In my opinion nothing works once they are blocked
magnífic
Well now you know why it's broke. Most likely because it was left hand and they cranked on it the wrong direction. Lol
Muito bom
it will not play
John you need a bigger garage! your running out of room lol
Yes tell the wife
doubleboost I'll pop over some time and let her know 👍
something wrong with the video
is ok now
Fucking nice work!
Do you have any video showing inside thread making?
Yes there is plenty to see
What language is that?
...'Almost sexual'... LOL
15 .100
Which language is this :-D
It tool is a Gorila
that was totally sexual dam i couldent believe she came right out like that haha
god
