An occasional fail is just called Real life. Your victories greatly outnumber any occasional minor fails, our respect for your work has been well earned. Your integrity sharing this is just another plus.
I can always respect a man that is willing to not only admit to making a mistake, but goes so far as to point out the error, so that others may learn form it as well.
That sinking feeling when you realise things have turned to poo.
Then there is the “rationalisation” phase of “can I fudge this?
And then finally the “face up to the failure”.
Thanks for sharing yours.
Thanks Keith. In this community we don't rub it in we rub it out. I'm sure that the greater take away here is that a train load of people like myself learned a valuable lesson about reading depth micrometers. We appreciate you and what you do.
"a trainload of people"? I see what you did there! LOL
This is a perfect video Keith! You’ve summed up what we need to do in our own situations: no cursing, no self hatred, no blaming someone else . . . Just an excellent solution! God bless! Your family has a wonderful example to follow!
Re the no cursing, I’ll note that we don’t have a full real-time camera record.
Bozo might come to visit you, but he lives with me. As an instructor, I tell my students that we usually learn more from our mistakes than our successes. And boy do I make mistakes! If I learn from my mistakes, I must be one of the smartest person Bozo knows. Thanks for sharing.
Me too. I am a trainer also. Radio, electronics and computers. Big stuff up potential.
Hey Keith, Dan here, I've had those days where everything is going smooth and as you said , oh no , mr bpzo shows up. I will second the comment of the viewer that said kudos with no foul language.
Your a lucky man to have Bozo only visit you once in a great while. Me, I’ve had to put an additional room on the house so he doesn’t have to travel so far so often. Enjoyed the video, thank you.
I wouldn't class that as a rookie mistake. It's an issue with mechanical micrometers. When I was teaching advanced machining we were strict on that micrometer measurements always should be double checked with calipers or other easy to use method (that it's less accurate doesn't matter, it's the coarse measurement that needs to be verified).
Cudos to you Keith for showing your mistake and thus help many more avoid doing a similar thing.
And also the attitude, you take responsibility and pride in your craft.
A great machinist makes a rare mistake and freely admits it. So be it. Your videos, dedication and example are an inspiration to many. Never forget that your splendid efforts are much appreciated. Very best wishes from York, England.
Good morning Keith great that you are comfortable enough in your own skills to share that not everything goes to plan, and "learning opportunities" can happen to the best of us 🙂
Takes a real man to admit he screwed up. Don't beat yourself up - it happens to the best of us!
Can’t tell you how many times I’ve read fractions on the wrong side of the inch. Thanks for making us feel better about our own mistakes, Keith.
It takes a big person to own up to their mistakes, especially when it’s a big one. Kudos to you for publicly showing this one. It gives the rest of us Bozos the confidence to keep screwing up.
It happens, luckily you have support to save you. Those castings ABSOLUTELY do not hace to be scrapped. The only critical dimension is the thrust face. Pad it with silicone bronze rod and then machine it back. It is a pretty common machine shop task. TIG it, braze it, or buy a small spool of SiBr MIG wire. Don't toss a good casting for something that can be repaired easily.
That would have been tempting if he'd been deep into the work, but recasting seems like the right call when all he has done so far is clean up the two faces.
The lesson here is not the thing he did wrong, it's the thing he did right - check your work after each operation. This is a small fail, waiting until you're fitting the finished part to find the incorrect dimension is much worse.
Brazing or flat knurling would work but if he’s like me every he saw the repair in the future he’d see his painful mistake all over again. Better to make all new parts to print and move on.
This was my first thought. Since new casting would be expensive and time consuming. It's even admittedly not a critical dimension.
@@d3faulted2 Couldn't he just shim it? If it's only 25 thou, seems like that would be a quick and easy fix. But I guess it would annoy him every time he looked at it.
@@jsaurman The crank pins are capped so a shim would need to be split, which won't work as they would drop out...
Takes a humble man to admit his mistakes. I'm not a machinist but I have had my share of ruined parts, mainly for being a gorilla. Sign it and auction it off as a souvenir. Thanks,
Tool & die shops have scraped a lot parts over those mics. I suspected what happened the moment I saw one in your hand. When I was an apprentice toolmaker, I was encouraged to buy a depth mic with the analogue digit display to overcome that deceptive error.
They've scrapped a lot of parts as well.
I'm not gonna lie: this is exactly the kind of mistake I would expect to make. But then, I'd say I'm at the Bozo level of experience with machining. But, I'm pretty expert in some other things, and know I make mistakes there, too.
Thanks for the honesty here, not just the admitting you made a 'rookie' mistake, but that you let us know that it upset you. We take pride in the things we do well, and screwing up is hard, and aggravating. It also says a lot about you that you were able, after a short time, to get past it and decide how to proceed.
It’s quite common to build up bronze bearings with whitemetal (you’d call it Babbit) so just tin one of the faces and build up with material +0.025”
Yes! I was wondering what "could" be done if a person had to. I was wondering how this casting could be built up. I was thinking Sillfos, or something involving less heat such as soft solder. Your method sounds reasonable.
@@bryanh1944FBH In 1917, and around that period, that would be done unless there were replacement castings readily available, like on hand.
We’re all human Keith and humans make mistakes. What makes a great man is a willingness to admit to them and clearly explain what went wrong. Well done, and thanks for a lesson we can all learn from.
I feel your pain Keith. I’m a woodcarver, and I have been working on a certain job for over a year. I was working on it one day and with a single misplaced chisel stroke I split my carving clean in half!! I was very mad. But such is the life of a craftsman
Some days the elevator, some days the shaft.
@@peterhobson3262 yup
Build it out with Tig. An evening in the shop, a handful of silicone bronze rod and you'll be back on track. And it's great Tig practice.
Man who never makes a mistake has never made anything. Well done for posting the video warts and all Keith.
I work in rail... when something like this happens, we call it a "Unique learning experience".
No one got hurt, nothing bad happened... just... sometimes things don't go right, and you learn from it.
Thank you so much for showing us your unique learning experience; it shows integrity, humility, and you've probably saved several people from making this mistake in the future
I admire your honesty in admitting your mistake.
Reminds me of what someone told me about making mistakes. The one person that claims to have never made a mistake either is a liar or never has worked. And I luckyly was taught to never see a mistake about something to be ashamed of, unless it was amassed "idiocy" or negligence that led to it. The most important thing, if you make a mistake, stand up to it and try to correct it. Also, look at how we learn Maths and stuff at school. We make mistakes, we learn why it was the wrong way, we try again. Mistakes should always be seen as a learning experience.
And while we as humans, working in a professional manner and a professional environment, have become extremely good at either preventing mistakes or catching them at such an early stage that we can recover, even in automated industrial size mass production mistakes happen. there might be an air bubble in a line, screwing up something, some piece of debris made its way into something, just something breakes (although we could argue if that would be a mistake in the first place, but there are usually mistakes that lead to something breaking, like lack of or improper maintenance or too much wear). And then add in a human. There might be that split second where we don't pay attention or get distracted. It is easy for us to mix up measurements or sizes. We might simply not fully understand what we are doing and what we should be paying attention too. There is plenty where things can go wrong. And sure, things at some point will always go wrong. That is also, why we put so many layers of protection and procedures in certain fields, flying an aircraft or just riding a car. We cover them in so many blankets, just to make sure we can allow for a mistake or two, because we can strieve for it, but we will never be able to completely avoid making mistakes.
You, sir have just shown your true colors. Not only are you very skilled, by facing the problem and admitting your error, you have shown yourself as a man of character which only makes me respect you more.
America needs more men like you.
Perhaps you could silver solder a bronze plate onto the casting to make up the difference?
It happens to us all Keith.
Depth mic's especially can scramble the old gray matter. Blame the new guy.😂
This is why I love this channel. Real life happens here, and you show how a real craftsman deals with adversity.
When I retired I took a two year course in machining at a local votec. Reading a depth mic was always a challenge, still is. The brain just doesn't want to process that way. Video's that show mistakes I think are the most valuable. I know I'll remember this one every time I pick up a depth mic. And that's a good thing.
Hi Keith. I am a fairly new hobby machinist (a whole 10 months under my belt) and have learned a truckload from your good self, Blondy, Abom, Joe P etc. I have been frustrated plenty of times because, being a rookie, I am very slow at machining so every time I mess up (which mappers plenty), there is a heap of time invested / lost. What makes it worse is that it seems that you guys are pretty immune to mistakes while I, on the other hand am not. While I guess it’s of little consolation to you, from my point of view, it’s nice to see that experts like yourself can sometimes get caught, so maybe there’s hope for me yet if I just keep going. Thanks for your honesty and uploading this… it’s a valuable lesson for me. All the best from NZ.
I'm 100% sure Keith and all the others made lots of mistakes as an apprentice. But they learned from them. Keep making chips and slowly (sorry it takes time) you get better. Churchill quote "Never give up, never give up, never give up!"
It's your life, doesn't matter if you really are the worst machinist, cook, knitter, ect ever. Are you doing what you want to do and overall enjoying it? If yes then rock on, simple as that.
Now if you get into designing and building nuclear reactors, or doing medical procedures that one very tiny slip can leave a person paralyzed rather than fix their condition then yes you need years of training and be selected from a very big pool that you really are among the best of the best of lol.
But mistakes will still happen if even if any of us was some of the best in the world. Look at all the mistakes both sides made in the space race and still do to this day.
Total bummer. I remember my first week in a cabinet shop and it was 3 weeks until Christmas. I was put on a job and followed the boss’ drawings exactly. They were wrong and shit hit the fan. I got reamed out for not knowing to question what I knew was a goofy layout. I was too scared to say anything. Oh well. Lesson learned. It’s not corporate America where you can hide a mistake. You own it and learn from it, and fix it. Those are character building moments. It made me a better craftsman.
Keith, that is the most common mistake a machinist can make being .025 or one revolution off on a micrometer.
And certainly on a depth mic.
Thanks for sharing.
At the end of the day, we're all human.
Have a great day.
Take care, Ed.
Mistakes happen. I have been a heavy duty mechanic for 35 plus years. 2 weeks ago I put seal kits in the foot break valves for a John Deere loader. It all went well till I started the machine. And one of the pistons shot out breaking one foot pedal and spraying hydraulic oil inside the cab. Simple mistake I got 2 hosed reversed and that’s all it took to pressure the wrong way and bingo big mess to clean up. Another week of downtime waiting for the 300 dollar foot pedal to arrive. Yes mistakes happen even with the best of of us. I haven’t had a mistake like that in years. So we just admit our mistake and move forward. It doesn’t do any good to fret over it
the one that doesnt make a mistake never does any thing i laud your honesty
I'll bet you said, "Oh Shoot"! As a carpenter and woodworker all my life one of our favorite clichés was, "its a darn poor carpenter that can't fix his own mistakes." But like you, I beat myself up terribly when it was a time sensitive and/or expensive piece of work. But you are a stand up guy and showed how easily errors can occur and how to take ownership of it.
This video highlights one of the perils of vintage tools and machines: they enable you to reproduce vintage mistakes. I’m glad this wasn’t one of those mistakes where the injury was to more than your pride.
A man who never made a mistake, never made anything. Like all of us, you will be kicking yourself, so there’s zero to be gained by anyone else kicking you while your down.
Look forward, move on and do better next time.
Personally I think it’s good that you show mistakes because everyone can learn from them & hopefully not repeat them.
Still one of the best channels around. 👍👍👍🇦🇺
Thanks for sharing your error Keith, I and others will learn from it. The person that never made a mistake has never done anything.
Everybody makes mistakes, that's how we learn. You could have deleted the video and never shown it but by showing this it probably opened some eye's. Thank you for your honesty and I'm not even a machinist but your instructions apply to more than just machining. Love your videos, keep them coming.
I love your humility, "Bozo comes to town" and "My brain did not engage at that particular moment." No matter the project, we have all done that. The only difference is that you advertise it to 247K people. Keep up the good work.
This man has a solid grasp on reality and we can all learn from his attitude toward a screw up. Unlike some other YT creators, he did not drop a series of F-bombs in an attempt to enhance his manliness. Keith is a true gentleman.
I've been a woodworker since the mid 70's, I've had my fair share of mistakes too. Moving forward is always a good plan. Hang in there !
Being good at woodworking means being good at hiding mistakes.
At least your material grows on trees!
Thanks for your honesty Keith. Bozo comes to town for you rarely. He has a weekend home in my garage and I know him well. This is a great lesson on how to handle mistakes. Thank you very much!
Ain’t nothin’ more demonstrative than an experienced southern gentleman machinist that ruins a valuable forged hunk of bronze!. Thanks for not publishing your reaction shortly after the clown show! Of course, you got a few giggles from your devoted friends and followers. Let’s all have a schnort of our favorite beverage together and good horse laugh at all our similar ****shows! 👀 St Marys, GA 🇺🇸
Life happens Keith. Don't be hard on yourself. Love your channel ❤️
Thank you for sharing. Bozo shows up in everybody's life, we have all been there.👍
That is odd Bozo is usually waiting for me in my garage. He must have learned where Keith lives. He is so helpful.
I applaud your honesty we watch your journey warts and all = thanks Keith
Hey we all fumble everyday. Still a great job Keith, Thanks for sharing.
Bad luck, but if you can’t make mistakes, you can’t learn. Great video, thanks Kieth.
Know the humbling feeling of mistakes, encouraging the way you stood up and educate proper way to handle bad situation.
You rock Keith. I appreciate your wisdom and humility
Bugger!!
Been there, done that, happens to us all at some point. Appreciate the honesty as it's something we can learn from.
Keith, you are such a fine, upstanding man. I admire anyone who can admit when they were wrong... but you didn't even have to post the video; we would have been none the wiser, yet you did it anyway. That shows a huge amount of integrity. Much respect, sir!
I think we have all been here before Keith . As someone once told me the man who doesn’t make any mistakes doesn’t make anything else either. Thank for all the videos you have taught me a lot
My Dad taught me that the person who never makes a mistake - Had NEVER done anything!
Hopefully Clarke will the new ones back to you ASAP.
I'm a long time member of the do-it-twice club. Glad to see you joined Keith.
Shit happens, it happens to the best and it's nothing special.
It is more rare for people to show their faults as honestly and openly as you do.
Chapeau Keith!
You don't want me to tell you why I check every micrometer-measured ID with a caliper 😏.
The only people who don't make mistakes are people who don't do anything. Most of us learn more from mistakes than good advice. Good for you for taking this on for the museum community.
Oh no! I made exactly the same mistake with an internal micrometer yesterday. Luckily, it was stock that came out of the scrap bin. If I can, I rough check with a digital caliper as well. Trying to do this type of work on camera means dividing your attention between two tasks. The perfect opportunity for Bozo to take charge.
I’m 71, me and my buddies have been laughing about just this same thing happing to us all, seems to be in the air, doesn’t help to be upset at self, but does help to double check and keep practicing to pay attention,, don’t ever let it put a damper on being creative, its all part of learning curve no matter how many years you’ve been at it……
I have great admiration for your honesty and sharing the experience. I am hurting along with you. Thank you for this.
At least he castings can be melted down and recovered. You are a class guy Keith.
I admire your honesty Kieth it just proves your human and don't hide your mistakes!
Thanks for sharing this in full. To me, it shows the integrity of yourself and others who share their stuff ups in public. We learn by our mistakes, as I have on many many occasions! Your integrity and professionalism are on full display. Thank you.
Keith your show is not a waste,this is a good learning experience for young machinist, l am also a member of the .025 thousands club . Retired machinist Rick M.😊
Put those up for auction, I would say. Or inscribe them as awards to the biggest supporters of the museum. There’s meaning in those castings that goes well beyond their mechanical specs. The pride and humility of craftsmanship might be the biggest part of it.
Nobody is perfect 100% of the time. My father always told me watch out for the guy who says he's never screwed anything up because chances are, he's never done much in the first place. What makes a good person, employee, machinist, mechanic, etc. is the ability to own up to your mistakes, and how good you are at fixing them.
AMEN!
The only people who don't make mistakes are people who do nothing, and liars. At least you didn't scrap something irreplaceable, these were already replacements.
At 16:43 : "That should know had better tud to do" Could not have said it better. Thanks for sharing the defeats along with the victories.
Further to my plea for not scrapping parts unnecessarily.
I would not have scrapped the originals to begin with. Rather, bore them round, turn an under cut on each side.
From a thick bronze tube, or casting if necessary, turn a bearing with shoulders which fits in the undercut. Split it and fasten with countersink screws to the original parts, screws will carry very little later load and will be invisible. If any problem with the applied bearings, these can be replaced more easily and economically.
Back in the day castings were cheap and machining expensive. Take advantage of that. Why spend 1,000 when can do with 300, people will enjoy the very same train ride.
Keith....I always admire a man who admits where the fault lays......best wishes from Orlando.....Paul
No problem Keith. This happens to everyone. Had the same thing happen to a part I was modifying for a friend. Misread the micrometer and over machined the bore of a sleeve. Made a new one from scratch and lost track of how much I had taken off on the ID and made one cut too many. Overboard again. Third time was a charm. Wrote down every step to machine out and marked them off as I went. Live and learn.
I feel your pain. Thanks Keith, for being a real gentleman.
Such is life. I usually double check myself with a digital caliper as a sanity check whenever there is room. Thanks for the video!
everything is a gift or a lesson, and if we learn anything from the lesson, that’s a gift too! takes a big man to admit a mistake. Keep on keepin on, Brother
The first part of correcting a mistake is admitting there is one, and, unfortunately, taking credit where credit is due. I really appreciate the fact that you do that, and don't just edit it out.
Isn't that the Pitts Keith..... I too know that feeling when you know you screwed up doing something you've done for years! It happens... commiserations and admiration for your honesty, which is why your channel is so appealing! 👌
The man who doesnt make mistakes, doesnt do anything.
Whenever I use a depth mic, I remind myself that I'm reading what I can't see hidden by
the thimble. Brown & Sharpe made various mics with slanted graduated hash marks
that made reading depth mics a bit easier. Also, I do a sanity check with my dumbest
measuring tool such as a scale or caliper rod and compare that to my depth mic.
Sad to see such a simple and expensive mistake Keith but I'm sure you'll get over it.
It was mighty big of you to share your humility with all of your followers on UA-cam...
I learned to chase a thread on a lathe when I was 13 years old, I am 80 now and after all these years as a machinist/toolmaker/hobbyist I still have to stop and think when I pick up a depth mike and usually check the dimension with another method of measuring. We just don't use them enough. So as I tell everyone i introduce to the trade or hobby the scrap box is your friend don't be afraid to use it and then show them my collection of Bozo stunts.
Hi Bozo,
This is what I was saying the last time I left you a message.
Check, double-check, then check again before making the cut, especially when its work belonging to someone else!
We don't want bozo in the shop again, do we? However, I'm so glad you released this video Keith. None of us are perfect, are we?
I’m so thankful that I never kept a list of all the perfectly good parts that I have ruined, although I’m sure my list would be MUCH longer than yours. Some of my greatest learning moments have come as a result of messing up!
Been there done that! I really had to stop and think every time I used a depth mic....even after many years! I know that feeling of "Oh CRAP....what have I done!!! "
"My brain didn´t engage properly"... Poetry in motion. We all screw up sometimes, how we deal with it makes the difference. I´d trust You with machining any day of the week. Kind regards
It’s crazy how we never remember our successes but always remember our failures. I’m sure you didn’t need any reminders but you sure taught a valuable lesson by posting the video anyway. Cheers to a better day in the shop!
Keith this is exactly why i watch you and emulate your ways! You own your mistakes! It’s very encouraging for newbies like myself, to help us take chances and push the boundaries of our know how!
It happens Keith. ! And look forward to the next step to get us all back on track!! It just pops up in the wrong time period. Thanks for allowing your human side to show sometimes.
Keith , one thing that i like about your excellent site is if you make even the smallest error you admit it upfront, it is noticable in the editing of some other creators they are not so "honest" Best Wishes from South Wales.
Bozo has caught us all at times.. I remember a Boss once told me.... the guy that never makes a mistake never makes anything!
When you've been doing something for a long time you don't make big stupid mistakes. You get so comfortable so you stumble on little things when you work like an autopilot. Perfectly normal, annoying though. That's also why accidents happen to veterans who have doing things for ages
Back in the early 60s I finished machine shop schooling and then completed my apprenticeship and I made some of these same mistakes. I look back and cringe but at least we can recover, yes this type costs and does not result in my understanding as some others might. The set ups I did wrong will always be a reminder for me to check more than once but even then once a cut is made the reality shows up that I had something upside down. Good on you for posting.
keith always honest to include mistakes,we all make mistakes just part of life i applaud you for explaining the error! hope it helps others.
If you keep working in a machine shop you will do it again! We all screwup and screwup again sometimes it hurts more but it happens. I ounce worked with an old machinist who would say "ant nothing but a thing and we can fix things" how true it is. Keith you do a good job of teaching and relating real shop experiences, keep it up!
Sometimes these kind of things happen on our projects and we’re working on them and it’s just a thing that happens to the best of us. Well KEYS it’s time to start at the drawing board again hit a new part out and start all over. Still be rooting here for you on the sidelines.
Keith, your are still a great teacher and humans make mistakes. Mr. Murphy has stopped by your place to see how he could help…😂! Great video content! Thank you
We all make mistakes. While a delay and a major pain no one was hurt and no damage as a result of the error except to an inanimate part. Hold your head hjgh my friend you're facing the issue honestly and openly. You're a good man with great skills. Keep after it sir!
Way to go to be so honest. It could easily have been easily hidden. My respect for you has just jumped up huge time. Kudos to you.
Cheer up Keith. There are exactly ZERO people watching that haven't botched something one time or another. I'm only disappointed because it made for a short video. 🙂
