The Haimer tip in the pumpkin is absolute machinist comedy GOLD.

I think what really makes this hit home for me as a machinist is the audio. The number of times I've said or thought "yeah that cut is looking perfect" an instant before I blow up an end mill is... A lot. Hearing other machinists do the same exact thing makes me feel a lot better about it!

As another self taught (And definitely still learning!) machinist, this makes me feel way better about some of the silly things I have done. The best part about making mistakes are the learning experiences that go along with them. Thanks for sharing!

I work with CNC and when you're an employee this isn't funny 🙈

2:25 we totally need that sign at work XD

Looked like most of the crashes was due to insufficient work holding.

This is fantastic. Just this morning a friend of mine was asking me if I'm cursed or if everyone breaks tools and ruins parts. I'm sending him this immediately.

Your 'bloopers' look like my normal mode of operation!

2:45-3:07 was pure gold.... no I take that back. the whole thing was pure gold John. Thanks for all the wisdom over the years. looking forward to learning with you for many more.

been a machinist since 98. i still laugh at these things which seem to happen all the time still.

Reminds me of the stupid stuff we used to get up to in our engineering lessons at school... unsupervised 15-year-olds in a workshop is a seriously bad idea! Two groups of us used to wind each other up, and we sabotaged the other group's open evening CNC demonstration. The CNC machine spent 15 minutes painstakingly cutting a hold-up-to-the-light relief picture of Anna Kournikova into translucent plastic. After a few sneaky changes, the head of department had all the parents huddled round watching it finish, only for the machine to pick out a massive tool, destroy the plastic, and machine a phallic symbol into the vice holding the work! So immature, but it was hilarious at the time! The moment we were left alone we were making swords, knuckle dusters, daggers, shurikens, throwing knives, you name it, we made it! We soldered hundreds of 12v piezo beepers together (each with a slightly different tone..) and hid it in the roof with a few batteries attached, making a horrible but tricky to locate whine.. we made canons out of the Co2 fire extinguisher, drew dicks onto every hidden surface imaginable, sandpapered the lenses in the laptop CD drives, and arranged every single one of the 25 laptops pointing towards the door, each one with "Meatspin" playing (along with sound, and the classroom projector running too). Unfortunately our head of year walked in before our useless teacher, and he hit the roof, bigtime! A friend's younger brother reliably informs me that our handiwork is still being found to this day, and we're still remembered as the worst class ever. I seem to remember we also took 15 soldering irons, arranged the tips into a ring and melted £50 worth of solder into a giant puck... idiots!

CNC- a faster way to get into trouble...

2:51 "I might only have 1 M8 tap, but you know what, let's try it!" The professional version of "Hold my beer!" haha

My favorite was the injection mold one were you said you did not want to plunge and it went straight down oh my gosh gave me a huge laugh

You can see that chip stream coming off. Isn't that awesome?! Screeeeeeeeeeechhhh!!!!! That made me laugh. Another great video John!

This video is just what I needed... My Tormach has seen it's share of broken bits, 'pushed" out of the way parts, vises that got milled over the years... Great to see that am not the only one that experiences this. I have a nice, albeit small, collection of bits in a box I made with my CNC specifically to collect these "errors".

Thanks John, it is your honesty and humility that make your videos so great. I am still getting over the struggle of wanting to make perfect videos and just put out ok videos as I get better at shooting video and machining. I recently watched a few old (2013 era) videos of John Grimsmo in his garage with his DIY X2 CNC conversion....made me feel less bad about where I am at right now!

These certainly make machining follies seem more routine rather than the "I never make mistakes" master machinist everyone knows makes it out to be. Every self taught is always learning, thanks for the video!

1:03 geiger counter flashbacks

Thank you John! We are human. That's how we learn.

That lower, nooooooooo :). Good stuff, thanks!

Plunging at full speed just makes you feel ALIVE doesn't it

I can't tell you how much better this video made me feel about the many mistakes I have made. Thank you!

Just came in from the shop after trying to rapid a #21 drill through an aluminum fixture plate because I forgot to set my Z. Sigh, time to pack up for the night. The drill did not survive.

That was awesome, thanks for sharing REAL experiences! People see videos of perfect machining and don't realize how expensive an "OOPS!" can be (or how often they happen!).

As an apprentice lathe operator stuff like this always scares the shit out of me. (luckily it hasn't happened too much to me!)

dude I can't say thank you enough for sharing all the vids and knowledge, once I get some money together ill see you all at the cnc training!

the air pipe hitting the camera and coming off the job, then it burning up HAHA.. so much precision and prep from these machines but it still can't account for a silly human error XD

Nothing that can't be buffed out 😆

For those of us who aren't machinists, little captions explaining what went wrong would be helpful. Some I understand, like not having the coolant/lube spray on, but others I had no idea what I was watching.

I really like your enthusiasm and honesty about being a machinist. Being a mechanical engineer myself I kind of understand the issues you guys have to deal with, but I would like to get away from the office and just spend much more time making parts. I envy you!

Love it! Man, I cringed when I saw the AR lowers! Lol. Keep up the great work John!

If you've ever ran a CNC this video will make your stomach twist.

Do you keep your broken endmills in a jar of shame? I have kept them in a GS tool holder case and am looking for a larger container to hold them all!! I wanted to do an inventory at the end of the year to know just how much money went to my education/training. haha

0:55 to 1:05 feel like I just tested my safety glasses without blinking.

the moment when everybody thinks you are such a professional cnc machinist but you know that stuff like this happens over and over again.

I will never forget the first time I had to tell my boss I broke a tool. He said "well it looks like your a real operator now"

Haha I was wondering when this one was going to come out!

Rule 1: Clamp the work Rule 2: Clamp the tool Rule 3: Calculate Speed - No Guessing Rule 4: Calculate feed/tooth - No Guessing Rule 5: Prove the progam properly!! - No assumptions BASIC STUFF by the way, loved 2.09 'Isn't that awesome!!!' as he ploughs through the vice LOL

My cheeks clenched a dozen times watching this.

Good stuff John!! 😆😆😆

John, that you so much for the videos. You have certainly helped and encouraged me and thousands of others.

This is soooo good. Admit it - we've all lost our Haimer in a pumpkin once or twice!

That sinking feeling in the pit of your stomach when you break a tool.... Had that for most of the video lol

"I might only have one M8 tap but you know what lets try it" Now those are some famous last words! Thanks for making this video was fun to watch.

When I do voice overs for a 6min video, i cannot do it in one go! I do up to 200 recordings of various sentences and sometimes even single words that came out wrong.

Glad to see some good hardy humor mixed in with all of this knowledge. Never a dry episode!

It's great to see that even these guys make machining mistakes often enough :) haha

That e-stop button really takes a beating when you're teaching yourself, doesn't it? 😂

Thanks! This video is right on time for me. Just getting started on a hobby mill G0759 and got pretty frustrated today. I have a looooong way to go and your video will keep me pushing on and learning.

Breaking a 3D dial tip on a pumpkin has to be the saddest feeling. Love the videos!

Love it! This makes me feel so much better about all the times I've crashed or flung parts, thanks for sharing!

The Ol' KZfaq motto; record takes in the 20's, publish and compile once. This was great man. There's a lot to be learned from mishaps, especially when shared. Pitfalls are so easy to step into when the one ahead doesn't call 'em. Thanks for putting out the slippery when wet signs for all us newbs. Not too bad on the crashes actually, I was waiting for one that just tore a half an inch of bit through a vice, but it didn't happen. You got the balance between babysitting and letting your mill take it's steps on lockdown :)

Yes. So good to see it happens to others as well as me. It's all so very much a learning curve.

Enjoyed...yet painful to watch...ouch!

Watching that AR lower receiver shift was hard to see. I hope you were able to save it. We built a reverse steering bike here too. In fact it's back in the shop right now because the UHMW gears I made for it didn't last. The client wants aluminum gears now. Should have it done and the video up by the end of next month.

4:43 Real professionals in action

I think it is great you guys are not afraid to admit you are human. anybody that tells you that they never crash are lying. I did CNC turning for 15 years mostly on Mazaks. Never got into milling too much.

I remember that backwards bike from Smarter Every Day.

Great video. All those times the Tormach stalled when you overloaded a tool? Your new Haas won't stop. A whole new level of scary. Trust me on that one. :-)

i was laughing really hard at the part with the sign that said "0 days since I broke a haimer tip" or whatever it said hahahah

i just love seeing errors made by the machines. tool bits breaking, flying chips, maaan, those are just awesome, although its dangerous. nice video

I can’t imagine setting up a machine. Then setting up a camera. Then publishing the mistakes. Well done! ;-)

thank you! I'm a self taught machinist as well and it is good to see that I'm not the only one making mistakes!

When the video started I was clenched as I knew crashes were coming. But I ended up laughing - I know I shouldn't but couldn't help it. 4:02 in particular had me drying my eyes! Your accidental deadpan delivery sealed it. I also see you have got really advanced now - at 4:21 you have an automatic part ejection system! I thought it was just me so thanks for sharing John . . . .

Great, wonderful, funny... having a blast! Thank you for sharing... and so nice to hear that you still can laugh about yourself... very important! All the best... stay save!

"Self-taught machinist" no kidding....

Thank you for sharing these It brings the reality back into this.

not as meany broken end mills as i thought. keep up the good work

the pumpkin one got me laughing so much

I sure feel like a nerd watching "cnc bloopers"

Now i feel much better, ive snapped bits for various reasons and figured a real machinist wouldn't do that. Thanks.

Always wondered why my father taught me extreme measures mounting a part to be machined.. Shit can get hairy quick. Cool video glad to see everyone still in one piece.

as someone who is in teaching to become a toolmaker... i feel those. i forgot to tighten the work in the wise a few times, and it's not fun. luckily i only work on a regular mill and not on a CNC, and the parts im making so far in my internship are not critical or expensive, and they can usually be repaired

I'll confess... wrong tool offset/wrong tool number got me more than once. Nothing causes your butt to eat your underwear more than watching a rapid Z turn your brand new, expensive 1" solid carbide endmill turning into matching bookends.

Look scary as fuck. Feeling more intense watching this than watching a horror movie in a movie theater.

ahahahahaha!!!! " how did you break your prob?" " on a pumpkin"

So awesome!! Thanks!!

we need more of these crashes :D

A guy running before me just snapped off a 7/8ths 2 flute end mill inside a .5 inch deep pocket in AL. There is two pockets and instead of going up in Z to get out of the pocket to go to the next one, he decided to go over in X and Y first lol. You talk about a loud SNAP! Scared the shit outa me!

I'm a self taught machinist, myself. I have to give my uncle Bob credit for teaching me conventional lathe work, my uncle Ernie gets credit for teaching me how to thread with die-heads, and spit tobacco juice into the coolant trough, and my Dad, for teaching me how to set-up box tools, or, roller turners. I'm retired now, and not being such a smart guy, my ability as a machinist is based on my tool collection, and, my collection of set-ups, and methods, learned from others. My Grandpa Lagerquist showed me that an old man, can outwork a young guy. I know you won't want to hear this, but if you can make a simple set-up, and even if you find yourself chasing clamps, it will pay off, man. Yes, you have all the equipment you need, for complex machining. In addition, you have business management skills, and programming skills, far beyond my simple hand programs. What I'd like to covey, is keep it simple, on low volume stuff.Mark Nelson

The Billy Joel song..."you're only human"....came to mind. Thanks for the video.

This is part of our job. Shit happens ;)

Getting on a bike in real life: No worries. Getting on a bike in a KZfaq video: Oh shit! How bad is he going to hurt himself?

Good selection! It was interesting to watch! Thank you!

This video is priceless! Laughing almost the whole time! Machinist humor for sure! Great video 😂😂

I engaged my safety squints for this one xD ;P

Part of learning to machine on manual machines is that you get a 'feel' for what you can get away with on part holding. The feedback from a handle is nice to teach you how much tool pressure you will have in a certain situation. Most of my part holding is with vacuum, so it is very important to understand it as once you lose vac, you lost the part. Starting out on a cnc makes it a little harder I think, you don't have that feedback from your hands, just sight and sound which are fine once experience has informed you what they mean. Thanks for the videos...

Watching these makes me super nervous 😂

It's amazing these contraptions work at all

I didn't see any carbides come off the tool and go through the window. Creating a magnesium fire because your cutting speed is too fast is a great way to make a memorable day.

I was FREAKING OUT!! Lucky you and your GoPros have all your appendages!

Does that company make any money? Looks like an expensive operation.

So nice to see that even the best make mistakes. Thank you for making some of these mistakes for me so that I didn't have to learn them. I DID find out however, that a #51 drill will plunge in at 20+ IPM at 10K rpm because I set T26 but not H26 lol.

tis the year of the great pumpkin Haimer crash nice video John, I was finale able to buy a lathe just a 9 / 20 inch but the price was right .wile you mostly mill you have still taught me a lot and I truly appreciate it. Thank you

This is my new favorite thing to watch.. CNC fails.

Damn some of those where gnarly man! lol

Came for the machines. Stayed for the burps.

amazing video John, remind me of when I first started with cnc, thanks daniel

Good one John...........I just crashed my new 770 for the first time today! ...... scary, i think i peed a little!
