John, one of those left-hand nuts would be a great giveaway as they are world-famous. Label them Twastard Nuts and sign your signature with a tool marker.
Who else remembers when John did this a few years ago...and cut a (beautiful) L/H thread? Yours is one of my favourite channels, John. I'm having a laugh at your expense, but I'm certainly not laughing at you. Happy New Year to you!
Excellent! Finally done! From my own experience: if I make a mistake and attempt to "quickly!" fix it, I get in a rush and nervous, it is almost certain that I mess up completely. I made a pretty expensive mistake a few months ago when I built a spindle. In the course of the assembly I forgot to install a bushing. I had to press out the bearings and ruined the entire job including the expensive spindle bearings as the parts were galling in the housing. I am certain that this happens to all of us. Admirable that you got it in the end - plus the blooper bonus(es) for your viewers :-) All the best and a happy new year.
When I watched the last video and saw that you hadn't reversed the spindle direction, I felt so bad for you. Then when I saw the out take where you engaged the half nut at the wrong point I really felt bad for you. Where I live we have an expression we use for jobs that keep going wrong. We say that the job is "snake bit" because every time you move, you get bitten again. Here is to the hope that 2021 finally dies and that there is no carryover of bad things to next year.
John, if you watch the close up of the threading tool. you will see how much spring you are getting which really demonstrates how many times one has to "spring cut" to get to dimension. Nice work, I did some threaded caps similar to this, they only had 3 threads so it was a necessity . Cheers and a happy new year to you and your family!
Anyone who says they havn't been there one way or another is someone who never tried in the first place. Never give up. A happy and safe new year to you and yours John.
John, your a diamond in the rough. After being back home this past week or so I can honestly say I have missed your voice. I've missed being back home in the north and to hear your voice really makes me smile. Watching you work is a pleasure for my eyes and ears. I hope you had a great xmas, I know I did, loads of food, mam's roast beef.... lush. I wish you and all your family the very best, big hugs all round and high hopes for the coming year.
John's a clumsy twasterd but when it comes to dropping drills, you certainly outclass John ! Brian - I don't think I'm ever going to get over that incident having seen the video. I don't think I've heard a more solid impact - and one that could have been a whole lot worse. Thankfully you can tell the tale. In recent years, I've had 2 vehicle crashes outside the house but vehicles are very soft and make crunching noises. Hope you've had a good holiday and all the best for the New Year - and finally something you may not have heard that's amusing. This is from a fairly famous British comedian, Spike Milligan and demonstrates the army attitude (he probably was in the British army) towards getting stuff done. He said: "If you hang a man, and it kills him, you keep on hanging him until he gets used to it."
When ever i cock things up i always call it R&D ( Research & Development ), I do a lot of R&D these days. Your camera work is very professional these days.
Splendid. What a guide to encourage the rest of us to the dark side of the lathe. Mine is presently set up as a welding jig for a sheared motor shaft, but there is not much room for the Tig electrode. It's a stainless part with sintered permanent magnets that I can't cook. And after that it is going to make mounts for drive couplers to stop the same thing happening for a fourth time! Piss poor design anyone ?
Let’s face it John you did a great job of the first one the milling the turning the threading if we haven’t made a mistake in our work or hobbies then we are all lying 🤥 baskets have a good one to you and yours 🍺🍺🍺🥳👍👨🏻🏭and to all the viewers 👍
Hi John Happy new year !!! many of us mess up but when I was working, the part time kids would come into the after noon shift, I had set up a secondary job in the milling machine with a fly cutter, but they always turn the Power switch in the wrong direction, breaking the carbide cutters to break. I made a bracket on the switch that they could not turn it the wrong way, when working on the lathe or repetitious work our hand always turn the switch the most command way. Hope you find it useful. Tom from Canada.
I think you've cracked it there this time, err, Reginald Molehusband - LOL - John, that name should bring back memories :) So, perhaps the tip is to set up the lathe for cutting right-hand external threads and then simply start the lathe in reverse after setting the tool up for the internal thread.
Some projects just are like that, aren't they. I was doing a simple one a few weeks back (probably more like 3 months, actually), and cut it too small. Ok, let's do another - a couple of cuts, measure, "Do I not learn?", got it half a mill under again! Third time I got it spot on. If I was making a nut like that, I'd just cut off a slightly long piece, and drill it straight through, then you can thread-cut the conventional way, no big deal. But that's of course less of a challenge [and wastes a bit of material]
John, You Should have taken MANY more spring passes, you could see the tool deflecting as it exited the part. 0.25 mm depth of cut is a lot for a full contact insert.
That was a lesson that I had to teach myself many years ago. Sometimes the solution becomes obvious when you return, other times the break helps to lessen the frustration.
Why did you not make the bar a bit larger as the deflection during the end of the cut was very evident. First rule of thumb is use the largest posiible tool shank. Cutting oil from the start would have probably helped as well as "build up edge" on the point of the tip would have been a problem as well. Ian New Zealand
Making up for being a muppet before, almost... You can use left hand inserts plus holder, to get the right clearance etc with off the shelf inserts. The best advice I've had for thread cutting is always cut a test piece first. Most of us cut threads so rarely that you're going to make a fecking mess first time. Better to mess up a test piece than something that matters.
The challenge that John faced was that he didn't have anything to check the threads with since it was for a motorcycle's front forks. It wasn't until this attempt that he realized that the ER32 block had the correct threads and therefore had a way to test the new nut.

Three lefts make a right... Thanks for another year of great videos John.

Well done, John, the home made tool really worked well. Glad you got it sussed out. Love the blooper at the end too. All the best. Mart in Solihull.

Nice shop made tool John, just in time for the new year😇.
Great spot on the ER 32 collet thread dimensions by a subscriber.
At the end... LOL! I know the feeling, some times you wish that you had never set eyes on the bastad thing...😂😂😂
Getting lots of practice on this job. That is how it goes sometimes. 🙂

Only tried thread cutting once but never internal or reverse. Reversing switch needed on the old lathe I think 👍👍👍
I knew u would get it John I think u have had enough of those nuts 🤣

Great video. Nice work John. Thank you for sharing.
Olá Jhon gosto muito do seu canal, um feliz ano para você e sua família, obrigado pelas dicas.
We knew you would get there. Some jobs just go like that!
Well done.

Third times a charm great job
Excellent job John, great video, keep'um coming..
HAHAHA laughed me head off ya old fossel haaa
ya bastard missed it love it John
Happy New Year

Lol definitely a bastard I’d lost those rejects for bid auction on eBay with those bottle openers

It's a out side bit for the lathe to cut oudside
Hoorah!

Third time lucky, eh John? 😁
Lots of movement in that tool as it exited the hole but all came out ok in the end, well apart from the outtake :D
One of those things
Third times a charm.
John, You Should have taken MANY more spring passes, you could see the tool deflecting as it exited the part. 0.25 mm depth of cut is a lot for a full contact insert.
YAY!!!!!!!!!!!
There are some times that I simply have to walk away from a project........
That was a lesson that I had to teach myself many years ago. Sometimes the solution becomes obvious when you return, other times the break helps to lessen the frustration.

Cutting oil from the start would have probably helped as well as "build up edge" on the point of the tip would have been a problem as well. Ian New Zealand
I have some smaller diameter oiler caps to make , The bar will also do those . Thanks for watching
Shit happens to all of use John it's nothing new without accidents half of use wouldn't be here
👏👏👏👏🎉

Couldn't rest until it was right. I can understand that. Happy New Year! Enjoyed watching.
