I just finished making a backing plate for my 12 in Atlas. I had to make a bushing for the plate as it had a 2in hole and the Atlas is 1.5 in. The only material I had was a piece of 3in square hot rolled so I turned it to the needed OD on my Myford clone. I bored it to the required ID for internal threading and that's where the fun began. After internal threading I took the piece out of the chuck and tried to thread it on the Atlas spindle. It was too tight! I had to remount the plate in the Myford clone and chase the thread. After much sweating and swearing I finally completed the job. If I had not watched your videos on internal threading the job would have been scrap. Thank you John for all your help by posting your videos. Rest assured you are not the only one to make mistakes. We all learn from each other.
I'm familiar with that OOOPS feeling. Thank you for sharing in your error, along with your successes. I like the changing camera angles. Always entertaining. Thank you.
What is so good john is that you making this mistake on purpose just to show us newbies what to do when we make this mistake, thanks for trying to be convincing! As if you would actually do such a thing, now I will know what to do when i screw up a project of similar lines ;)
A mistake is just a part of the cost of doing business. Everything can be fixed and I bet you'll do a fine job correcting the mistake! Thanks for showing the good and the bad, an honest man! ....13
What a bummer! Sorry to see it happen, especially to a guy as nice as you are. At least you are the right man for the repair as you seem to always pull a rabbit out of a hat when the chips are down to use a couple of fitting cliches. Heading over to watch you save the day in part two...I've got my fingers crossed even though whatever has happened has already happened, I'm a fan of happy endings. Aloha...Chuck
It is reassuring that even a "master" like John makes an occasional mistake. However, John being the great machinist he is, the "fix" will be beautiful, and possibly better than the original! ;-) Just look at the big boring head for an example... The micrometer dial that he made to replace the broken one looks like a work of art! I wish I could recover from flubs like that! Well, I guess that's why I watch religiously; I have a lot to learn. John: Glad to hear that Debs is doing well. We're always thinking about her. She's a tough one! All the best to you both, Bruce.
I reckon you should take it easy for a week John. A video tour of your storage options such as your holders behind the lathe etc should be a nice welcome distraction.
When I was an apprentice we machined quite a lot of cast iron, the chips were always in demand from guys with citrus, all kinds, they used to sprinkle it around the trees, it was supposed to sweeten the fruit, not a problem for you I doubt in the UK. Clive Brown
Ho Man That's a Shitter, but thankfully recoverable. Glad to hear Debs is doing well, loved the Christmas one with you both. Did you contact Macmillan? They were brilliant for my Sue and I, totally independent of the NHS but work alongside them and are independent of the Doctors, which means they will tell you EVERYTHING you need to know. Hope Lady luck stays with you both.
I feel your pain, or at least almost. I recently overshot a few measurements on video. At least it was just on cheap bar stock and I could start over easily on the biggest one. I applaud you though for showing the oopsie and then continuing on to repair it.
I hate it when that happens, in fact it started happening far to often, kept misreading the dials with my aging eyes, prompted me to get a dro and now I'm pleased to say the feck-ups are back down to acceptable levels!
Just out of interest Mr Boost. im local to you, from the N.E. coast, Seaham Harbour. Introductions out'a the way, im wondering why you used cast iron? whats the reason or reasons for using this and not a hunk of cold or hot rolled steel?
I think a sleeve would be a good idea, no matter what. From the look of the boring chip, I would guess it's cast steel. It looks harder than iron and puts out chips rather than "powder". I had lathe operators who would sneak up on cast iron and immediate take the edge off an HHS cutter or drill. I pounded on then to bring it down like they meant it! Carbide tools and inserts saved many a cast iron rookie. It comes so naturally, we tend to forget we learned the hard way... :-))
Bit of a bugger but we've all done it...I set a tool wrong at work last night...got a figure in my head for a different diameter to what I was setting the too, off...only 35thou but still, took an undercut below a minimum size and then started again!
Sorry to see you have to do some repair. Tom Lipton has made a number of videos fixing his bozo mistakes. It helps the rest of us learn how to hide our errors! Glad to hear your wife is doing well.
Owch, sometimes even just the tool pressure on a spring cut is hard to judge and results in an oops. I'm sure you'll come up with a decent fix!! Colin ;-)
That's a bit of bad luck John. I've always believed that we learn more from our mistakes than our successes. The fix should make for an interesting video as well.
John, Sorry about your part. It will be an easy fix with a steel bush. I know you have a lot of things on your mind with Debs, so take it easy. It's better to mess up a part than your hand! Dave
"Gentlemen, i have done again all the calculations, our project is impracticable. We have now only one thing to do...achieve it!" Nothing is impossible, if you have the ideas and the will to do so. :)
Obviously a Geordie best machinist in the world a served my time @ parsons 25 year ago in the heavy shop been an applications engineer for WFL FOR THE LAST 20 year but I learned everything I know @ parsons where did you serve your time ?
Of course, I've never bored something too big or put a thread in the wrong place and had to plug it (on say a DSG lathe :( ) oh no no not me .... oh, that that sleeve is hardened for strength and that hole there is a spare ... it's big to allow for adjustment...
Bit of a bummer John. But the man who never mad a mistake never learned bugger all. Pleased you didn't hide the fact - too many 'perfect' people in the world already.
We all get sloppy at the lathe sometimes , seems like usually early on in a project. We know damn well not too towards its end. ..We have to be in the moment 100 %, Keith Fenner is good at that when it counts lol
that happened to me so many times for so many reasons, sometimes I just don't look at the dial sometimes I don't measure but all the time i noticed I keep the calipers tilted a bit, a friend saw that , told me "measure again fool you are dead on the money with that , measure again you are measuring with your calipers tilted ,dumbass!!" indeed I was... mr. Bozo is everywhere.
Always a pleasure to watch your videos mr Mills. Your close ups are the best I've seen on youtube.
Thank you.
Thanks for that

Not to worry. The man who never made a mistake never made anything. Good video for everyones benefit.

Thanks for the kind words

I will have to fix it

Thanks Bruce
Glad it looks like you know how to make the repair. Looking forward. Thanks for sharing your knowledge.
Thanks for keeping it real and honest John! Refreashing nowadays. We've all been there. Tell Deb she is in our prayers!
Thank You
Mistakes are how you learn new things, glad I am not the only one that has them .
I saw your wife fixing your jelly roll thing. Nice to see she is looking very healthy.
I reckon you should take it easy for a week John. A video tour of your storage options such as your holders behind the lathe etc should be a nice welcome distraction.
I was planning a sort of shop tour
Perhaps you could combine your shop tour with Micks shop tour as well?
When I was an apprentice we machined quite a lot of cast iron, the chips were always in demand from guys with citrus, all kinds, they used to sprinkle it around the trees, it was supposed to sweeten the fruit, not a problem for you I doubt in the UK.
Clive Brown
fantastic close ups john
Thanks Andy
No such thing as problems...only solutions!
Minor set backs (my old boss used to say)
Ho Man That's a Shitter, but thankfully recoverable. Glad to hear Debs is doing well, loved the Christmas one with you both. Did you contact Macmillan?

What you see is what you get with Me lol
Been there, done that. I am sure you will recover the casting. Thanks for sharing.
I will fix it
unlucky John i feel your pain im always doing it glad Debs is doing ok cant wait to see the fix most of my mistakes go in the scrap bin lol
I do have a scrap bin lol
I hate it when that happens, in fact it started happening far to often, kept misreading the dials with my aging eyes, prompted me to get a dro and now I'm pleased to say the feck-ups are back down to acceptable levels!
I was just not concentrating fully
Easy done, too easy!
Fix it I will! That's the attitude!
I have to
The casting was pricey lol
Just out of interest Mr Boost. im local to you, from the N.E. coast, Seaham Harbour.
Introductions out'a the way, im wondering why you used cast iron? whats the reason or reasons for using this and not a hunk of cold or hot rolled steel?

I pounded on then to bring it down like they meant it! Carbide tools and inserts saved many a cast iron rookie. It comes so naturally, we tend to forget we learned the hard way... :-))
It is good grade cast iron
doubleboost
From the chips when drilling it seems to be ductile cast iron.
Shit John that sucked that the bore was off, but I bet the fix will make a good video too
Bit of a bugger but we've all done it...I set a tool wrong at work last night...got a figure in my head for a different diameter to what I was setting the too, off...only 35thou but still, took an undercut below a minimum size and then started again!
Easy to do

Easy mistake to make
John,
Sorry about your part. It will be an easy fix with a steel bush. I know you have a lot of things on your mind with Debs, so take it easy. It's better to mess up a part than your hand!
Dave
Dont worry about it. Its not a total scrap job and you arent the first guy to screw up a part and Im sure u wont be the last.
Easy fix
"Gentlemen, i have done again all the calculations, our project is impracticable. We have now only one thing to do...achieve it!" Nothing is impossible, if you have the ideas and the will to do so. :)
Obviously a Geordie best machinist in the world a served my time @ parsons 25 year ago in the heavy shop been an applications engineer for WFL FOR THE LAST 20 year but I learned everything I know @ parsons where did you serve your time ?
Of course, I've never bored something too big or put a thread in the wrong place and had to plug it (on say a DSG lathe :( ) oh no no not me .... oh, that that sleeve is hardened for strength and that hole there is a spare ... it's big to allow for adjustment...
I cut it 3 times and it's still too short! Happens to everyone...
Bit of a bummer John. But the man who never mad a mistake never learned bugger all. Pleased you didn't hide the fact - too many 'perfect' people in the world already.
That wont be the last time lol
don't worry about it john if you don't fuck up you never learn anything, the important part is you can fix it.... chin up mate.
BOLLOX!!!
It's a shame but i'm 1000% sure you'll bush it out to perfection ;-)
We all get sloppy at the lathe sometimes , seems like usually early on in a project. We know damn well not too towards its end. ..We have to be in the moment 100 %, Keith Fenner is good at that when it counts lol
Keith is just good lol
Bugger!
I hate when Mr. Bozo shows up. At least there's a fix.
No fun but at least you can salvage it.
It is fun once it is fixed
that happened to me so many times for so many reasons, sometimes I just don't look at the dial sometimes I don't measure but all the time i noticed I keep the calipers tilted a bit, a friend saw that , told me "measure again fool you are dead on the money with that , measure again you are measuring with your calipers tilted ,dumbass!!" indeed I was... mr. Bozo is everywhere.
Should have used your snap gauges
I will next time lol
I think a
is called for
There was quite a flurry of them
Bugger.
It was lol
bummer, not nice when you do that. no doubt you will fi it.
I will
Thanks for watching
