Retired machinist of 42 years in the family "job shop". Toughest part that I ever machined was .507 dia .303 long copper with 14 holes tapped 2-56 X .098 bottom. I set up a tool holder with bees wax that our resident old timer had me try. Went from zero tapped holes to completing the entire job with zero broken taps. 2600 piece order. Always listen to the old timers, he retired at 89 years old and still came in a few days a week just to answer questions right up until the day he died at 94. I really miss him.

Nice work! Reminds me of an old cartoon where an entire tree was lathed down into a single toothpick.😁

His considerations on stress-induced runout made me realise there are so many things i don't know. Sometimes you watch these gents, think it is easy because they make it look easy and suddenly you understand that there is so much experience you need in order to get the job done it is almost frightening. Still glad i subscribed.

Being a filmmaker before this trade I can really appriciate the time you put into getting the extra B shots and graphics

this makes my day..an hour long edge precision video :)

You taught me more in one hour than what the shop I started at has taught me in 3 weeks, thank you!

Not a machinist just like these videos but you have changed my attitude towards machining by making it straight forward and something I could do. I’ve watched many guys over the last few years but your video is the first one where I could picture myself there because I can understand your description of the work being done. I’m a heavy diesel field mechanic and have subscribed.

What a great video. I just finished watching all of your other videos and really enjoyed how you explain how you go about setting up the different parts of the project, It is also great to watch the machine at work.it is like pottery in motion. Thank you for taking the time to explain the different parts of the projects and how you set them up. Looking forward to seeing more of them

Chip conveyors only work when you don't need them

This is a terrific instructional. You take the time to provide not only a clear description of what you're doing, but to also call attention to the possible pitfalls to look out for. Thank you for taking the time to make these videos!

Precision required and precision delivered. No substitute for your experience, skill, and extreme level of detail. Thanks for sharing!

I am thoughly impressed with the detail you took with the setup alone, I have about 35 plus years of inspection work in metal turning. I have worked with some of the fresh out of school kids that just want to do everything as fast as they can, it was a pleasure to watch a true craftsman.

It's good to see that even with high-end machining you still need that human touch to fine tune the results. Thank you for sharing your day.

Incredible Peter, I like to think I'm pretty cool headed when performing tricky work but I admit I caught myself gritting my teeth a couple times while you were performing the work on this job, well worth watching to pick up subtleties of taking on such a job, thank you for posting.

I had no idea that thing would move that much when the center was removed. That blew my mind.

Your videos are gold! I learned more about stress, center drills and shoveling chips that I would have hoped for. Thanks for sharing your expertise!

'Thanks for watching'??? Oh no, no, no, thank YOU for sharing!!! Always enjoy when you share, period.

What an enjoyable way to spend an hour... Thanks Pete!!!!!

What a fantastic channel! To go to the trouble to show the setting up of the 4 jaw and the steady rest is above and beyond. I remember being shown how to set a 4 jaw while I was an apprentice. Looks so easy until you try to do it yourself. Big lump in the chuck, slacken the low side jaw, tighten the high side, then face not true, try to tap face true, part drops too far tighten jaws a bit, then can't move it at all, get face true but now OD out ... round and round in circles. Gets a lot easier with practice. I imagine the steady rest is even worse. You show everything that can go wrong and how to find out before it's too late. Brilliant training video. Worth every one of the 1.5 million views. Keep up the good work.

I just wanted to thank you for this video, I never had exposure to this machine or methods before but, I always wanted to start working in the field. So, really appreciate your explanations and reasonings, clear and understandable to follow your thoughts well. Thanks again.

You know you're looking at a professional when he makes more chips in one day than you've made in your entire life

2000 pounds!!!! Moving it effortlessly in that shop is the most impressive part of this video

I am an electronics engineer and an volunteer firefighter and own a few Hilti cordless tools because that is what we carry on our heavy rescue truck. I actually used my drill once, though I can’t remember why. So... I have zero clue how I ended up here. But.... I stayed and watched the entire video. AMAZING!!! Thank you sir. 👍🏻

Could save yourself a lot of pain in op2 by using a small bung/faceplate against the end of the part with the tailstock applied, skim a steady band. Apply your steady. Re-face the part and do your end hole so it’s true to the band you’ve just essentially free-turned without any pressure on the centre hole. Now you can engage your centre and turn it all true to the hole you’ve just made. Saves faffing about with chapping true and nipping/un-nipping jaws true with a DTI when, in essence, you’re truing up to something you’re going to remove in the next hour.

I love seeing other machinists thought processes, my old boss who taught me everything about machining who’s been a machinist for over 40 years taught me about stresses induced runout when I was machining a similar part to yours, it was only about 5 thou, and didn’t matter for our parts. But it just goes to show much there is to learn in this trade

I hope the customer sees your video, so that he can appreciate your dedication and passion. Great work as always!

New to the channel and the content is great. Really appreciate your skill, commentary and explanations. I learned a lot. Thanks for all your efforts. Paul

You learn something new every day!! I had no idea you could do that with a centre drill!! I will definitely put that to use.

That is an interesting fact about center drills

Very precise centering and turning methods. A superb and possibly unique kind of analysis. Thank you.

Very educative, you did all my tricks to get rid of stress in material. I work on 2 axis Mazak machine, so its a pleasure to watch your videos on this wonderful Mazak machine.

Lots of valuable lessons even for the home machinist. Thanks for taking the time to explain and demonstrate.

You would be a great mentor for any youngster starting out in the profession. Great vdeo!

Nothing but true professionalism right there.

Great work, you’re a fine journeyman. I really like how you keep a viewer involved by saying how “we” are going to do this or “we” are now going to do that, it’s excellent engagement.

An artist, a true artist! I was mesmerized for over an hour... one of the best hours in my life. Thank you... your highness.

Non machinist here... Absolutely fascinating. Meticulous, mesmerising and astonishing.

That center drill fact was something I never knew but am *very* glad I know now as it is incredibly useful! Thank you for teaching me something valuable that my college education did not

Thank you Peter for another interesting video, I learn from you every time I watch one of your videos, and this time we were really spoiled by over an hour of video.

Thanks for the video Peter. I very much appreciate these longer videos.

This was in my recommended and I watched every minute of it. Absolutely fascinating. Well done.

"Cutting Edge Engineering Australia" is also interesting!

Quality content right there. Nice work, sir! Really enjoyable video and process of a pretty difficult part. Good job!

Hey, as a machinist from germany its really nice to see stuff life this just the whole process of a part, i really enjoy watching your videos and see how you make this big parts ^^, keep going doing this its so satifying seeing removing so much material

Just found your channel and I'll thank you for what I learned in just this video, I subbed immediately. Now it's you and Kurtis over at Cutting Edge Engineering as my vote for best large scale machining channels on YT.

Just stumbled across your channel, great stuff. Greetings from Germany

Really enjoyed this video, I'm not a machinist but found this very interesting, thank you for showing all the details.

Excellent work. Another good reason to dial in the feeds and speeds, so you don't have to fight a giant swarf monster to clean out the machine.

Oh Man what a work,if you can trepanning some material here where I live material is so expensive it becomes complicated removing so much.warping is something to consider.

.001 of runout over 34 inches!! Much respect

Seeing you work is a pleasure for the eyes .. my compliments for the high professionalism. Amazing.. Good job from Italy..

What a nice long video. Well done. :) Seems pretty evident as how you got the part. Geometry appears rather simple. But I'm sure other shops didn't factor in the runout and stress as much they should be. The amount of double checking you did on this, is nuts. Certainly doesn't look like a load-and-go job. Have to treat each part, like it's the first one.

animated overlay timelapse montage was so cool! Great edit - and great content as always. Thank you

Very nice. I noticed that some of the micrometers had "For Reference Only" labels on them. When I worked for the USAF, I used to see that on things that came back from PMEL (Precision Measurement Equipment Laboratory) that hadn't passed or had expired. They usually worked just fine, but you couldn't use them for inspections or periodic maintenance. We used to have a torque wrench that was used for an annual inspection, but it still had to go in for calibration every six months. Madness.

I love seeing a wee little test indicator attached to such a ginormous machine!

Experience at its finest. Great job fellow machinist

Nice explanations throughout for those of us who are mechanically inclined and curious but have little or no 'hands on' machining experience (although having done software development in a group that did fancy, for the day, CAD/CAM over 40 years ago I have _some_ out-of-date exposure). One thing I find myself thinking when watching this and similar videos is how much time is spent on centering (although, obviously on this job with the amount of material being removed it's a quite small part of this total job). It seems that much of this could be done more quickly by "computer + sensors + hardware" under the guidance of the machinist (including specifying such things as max/min jaw pressures etc. as the machinist has a sense of the "grippiness" of various finishes/jaws as in this case). The spindle/chuck could have timing features (maybe at this class they already do) and a "digital" dial indicator being read by the computer. With that, the computer can do the trig to take an initial guess at which jaws to tighten or loosen and by how much and then actually extend a tool to do that to each jaw. Rinse and repeat until spec is met (or computer throws up its hands and cries out for a human machinist). Each iteration would take into account the change over the last try to temper the amount of torque to apply to each jaw adjustment. For extra credit, add a variable strength pneumatic "bumper/vibrator" to replace the hammer and couple that with three digital dial gauges around the circumference at the tail end - the computer could apply force in increasing/decreasing levels (up to constraints specified by the machinist) to the "bumper/vibrator" and turning the piece while monitoring the effect so relatively little "oops, went too far". I suppose version 12.9 of such a system would actually take into account the mass of the piece being centered (assuming a full CAD/CAM system, not just an assist to "old school" machining) to work more quickly and have a wide array of scenarios it could adjust to - but that's probably a bit beyond what would be needed for an MVP. Since this is so "obvious", I assume this already exists (although I've never seen it) or it's a ridiculous idea that has been tried many times and failed for economic or technical reasons :(

Just found your channel, subscribed. Have missed this kind of large scale machining since Abom gave up his day job.

What a remarkably generous man. Give you faith in humanity.

Well done, nice work. I probably would not have thought of that strap trick for finished part removal. Sweet.

Thank you for taking the time to make your videos while you're working!

The stock is not perfectly round. Peter: Hold my indicator... What a way to start the weekend

Great video and a good example of how much manual labour, thought process and experience goes into making quality parts. Most people including bosses always think CNC is just putting raw material in the machine and press the start button and while the machine is running you can handle three other machines as well. OH NO.

Good video thanks for sharing! It's never fun when the part becomes magnetized!

Thing just got real when you have to shovel the chip into multipal 55 gallon drums.

I always appreciate someone who is excellent at what they do. Compare that to the people we come into contact on a daily basis. My favorite quote from a computer tech support person is “That SHOULD work”. I always tell them is “WILL it work or NOT?”

That machine is amazing. 1/4” depth passes, jeeze. Your shots are great

Wow that is one hunk of round stock now enjoy machining it up. That is one nice lathe machine set-up also.

You tube algorithm said...you need some precision metal machine work in your life...me..."ok". Very interesting.

2000 LBS start, 140 lbs end. Perfect job to hot forge. But, if you only make two, not worth it, unless you already have all the hot forging equipment. That part is just asking for it though! Great job, very well done.

Great tip on the center drills! Thanks for videos!

Wow, that machine. I'm drooling watching this thing run.

Watching this channel and watching the Abom79 channel illustrates vividly that the modern metal lathe was invented in 1751 by Jacques de Vaucanson as documented in the Encyclopédie. Thus these two channels demonstrate 270 years of accumulated technical knowledge, which has amazing depth.

I'm amazed that a machinist like this is still working with inches.

Awesome video Peter. Love watching your process

really enjoyed this, thanks so much for making and posting, Paul

Don't know how I got here...but I loved it

have you filmed you shoveling all those chips? I love hard work, can watch all day!

The amount I learn from your videos is insane

Thanks Peter. A very enjoyable hour.

Its amazing how an engine block sized chunk of steel weighs as much as my entire old car.

It's a shame the chip conveyor broke, hope you can get it fixed soon.

I’ve had to get similar work on long parts trued up in a lathe an old timer taught me to use brass shim’s about 1/8 thick on each jaw that allows them to be tight enough to keep the part from falling out but allowing movement when you adjust the runout at the far end to true the part at each end. This way you can cut two steady rest spots that are 100 percent true and allows for easy adjustment. You can switch back to your 4jaw chuck solid jaws without skipping a beat.

I have a stop I put in the chuck. It has a landing that spigots in the chuck bore. It has notches cut in it so the jaws can still close past the bore of the chuck. I have a thread 3/4" unf tapped into it. The bolt has a large ball piece welded to its head and I have adapted a G clamp foot to it. I can them pressure hold a workpiece between centers just like how you pushed your workpiece in at the beginning of the video. By holding the workpiece away from the back face of the jaws, you are not fighting the squareness of the stock. When you get close to size and want to release jaws to minimize stresses and let it relax or normalize it doesn't change longitual position. I didn't know that about centre drills. Helpful tip!

"That's not a lathe, now This, This is a lathe!"

I’m am a sophomore student at a trade high school studying precision machining (manufacturing) and I was wonder if you have any tips or advice

You sir made Data from star trek jaw dropped, with your meticulous skill...well done sir...edge precision engage.

Nice to see the way you work. Quality work!

In our next video, we will make coasters from this 6" slab.

It feels like someone should start to forge round stock with flanges: easier to cut off 3x excess length, than to turn down 3x excess diameter... They may even become a standard if there isn't one already.

Great video Peter you are very good machinist and I really like your videos!!!

Engineers create the component designs through calculation, CAD/CAM and in depth analysis. But it's craftman like this man who bring it to life. Technology may have got more advanced but you will never find a replacement for skill, experience and attention to detail.

Видео о том как перегнать почти тонну металла в стружку

Wow, they absolutely needed a solid piece huh? Couldn't it have been made from two smaller pieces, welded, then turned? Geez, 90% of the stock turned to chips. Also, using a shovel to collect the chips: LOL, I use a little paintbrush.

It’s wonderful to watch you Chris I’m retired now couple years rent a HAAS TL-3 it had taper compensation I enjoyed your expertise to make your steady rest run part true. It comforted me to see you take prefinished cuts as I had difficulty holding size and taper otherwise

Back in 1971 I cut a 8 inch dia x 8ft long Acme thread. Had to take a truing pass after each depth of cut to straighten the shaft. On another job on a Lucas Boring Mill, I removed over 5000 lbs of material out of an insert pocket (14" deep) in a Die Cast Mold base. Fun stuff!

I never realized that about centre drills, thanks for the tip.

As always you came out with at great result :) I wish myself an Integrex, its an excellent machine.

Damn that’s a lot of chips! And that’s one hell of a chunk of steel! I’m just a home gamer so I just enjoy watching stuff like this even though I know nothing about machining, I just find it interesting as all hell. 😎

That is by far the largest lathe I have ever seen. I'm suitable impressed 😁
