This is a lathe job where I had to machine a piece of cast iron tubing. Face, bore, and turn OD to specs. The material was 17" in length. I'll show you how I tackled it.
Ahhh makes me proud to be a machinist (in my imagination atleast) the last thing i "machined" was the shaft of a running honda trash pump engine, turns out its bigger than the ones made for pullies as well as not having a key way, just borrow a harbor freight die grinder with a cutting wheel from the tweeker down the street, cut the keyway half ass squaw, get papa's old mill bastard out and start millin away, pretty soon you avoided changing the crankshaft with one you have laying around that would work perfectly, why? you ask, well cause sometimes the hard way is more fun and rewarding, so when they ask "you build that motorcycle yourself?" i can say "yea and i machined that shaft so that pully would fit and i did it in my front lawn with a file", hopefully then they say "kid you got a bright future, my buddy works at a machine shop if you ever need parts made", im the kind of 17 year old kid who pulls up to your run down radiator shop on the edge of town on a bicycle that goes 50 miles an hour and asks "anybody got a tig welder?"

I totally agree Courtney H. Your video productions are the best. I do need a little material education on the cast iron being turned. Your getting chips and I was kinda expecting more fine particles and dust. One of the TH-cam machinist was concerned with the dust getting on the ways when turning cast iron. Maybe a quick explanation of the material again. I really do learn from you as you change the tooling and you explain why, Thankyou.
Courtney Harrington Some people like to drape cloths and such on the ways to collect the dust. I don't worry with it. The way wipers do there job. Just clean up everything when your done.
+bjr E. WA Likely Keith Fenner. I don't recall ever seeing visible wipers on the carriage of his Clausing lathe so possibly it doesn't have them. I know he designed/made/installed a set of them on his small lathe along with an automatic oiler system.

:44 - Man, I feel ya on that. When I worked in a precision prototype shop, plenty of times we had no idea what we were fabricating. We didn't need to know. We got a print with material, dimensions and ± tolerances.

@Kevin Ray I second that. Though hopefully I will go to school to become a machinist, right now I just have a little 9 inch south bend lathe I've been doing little projects with. I've learned allot from Adam.
I've been an engineer for 38 years now and sadly for most of them it has been working on cnc machines. I still prefer to work with manual machines though. It's great to see the skills it takes to produce a component. I love watching your videos. Keep up the great work.
A great video. I am 70 years old and have been an Engineer all my life. Glad to see that the old skills are still being used and not forgotten. Well done
When I was a little kid I used to haunt any construction site in town just to watch how things are done. Thanks for making me feel young again, and just like back then, I think I've learned something. Thank you again. J.
I'm working my butt off to afford a lathe and mill. I own a business so time and money are in short supply. I've learned so much academically from you and others on TH-cam like you, Adam. And a fellow Florida boy at that! Can't wait to start applying the theory I'm absorbing into skill building and practice.
If they're going to be for production pieces, then you should lease for a coupla yrs and make the money from the equipment to pay and buy out the lease. You should be able to write off running expenses while leasing and write off wear and tear after purchase. I know a guy who bought a small lathe and small mill (both manual) from an auction and already had a small contract for simple parts in good quantities. He hired a machine operator to make the parts and made enough money in 6 months to start buying decent CNC machines and to hire a CNC machinist. Now, he owns big.
I never tire of watching you at work on these great old machines! I had the great good fortune to have worked at Lawrence Livermore National Labs back in the 1970’s and 1980’s, learning to make chips on all the old machines - most from WWII, but rebuilt by their in house mechanics. Watching these old craftsmen scrape the ways, and make those old lathes, mills, etc. come back to life was a real education for me as a beginning machinist. Today, nearly 40 years later, I miss the smell of the coolant, the smell of those raw materials, the feel of the tools in my hands, the moment of victory when I first learned to single point threads after grinding the thread cutting tool bit. The joy of knowing you can literally make ANYTHING of metals, machinable ceramics, and plastics, and even wood when necessary is just great! So, I appreciate your skills and your fearlessness to take on any job and get it done in fine style.
I'm not a machinist, but I do enjoy watching the process and the way you do things is very calming and enjoyable aside from being accurate and precise. I hope the company you work for understands what an asset they have in you. I know that the TH-cam community certainly does. Keep up the impressive work!
Really enjoyed your video! Reminds me of the times I would bring a dinner to my dad while he worked at a tool and die company. So enjoyed watching my dad work lathes and milling machines! He was a stickler for accuracy as you demonstrated in this video. Please continue to put these videos out there so people can grasp how things are made.
Brings back so many memories from my dad who was a machinist, he bough a small table top lathe after he retired and started teaching me but got sick and passed before he could teach me much. So much talent lost from his death. You are a true craftsman sir. Thanks for the memories.
Bravo ! Great to see a guy using an old machine tool to make a useful product. Wish my father was still around to see this. He would have enjoyed your skill as much as I do.
Very true. I remember in high school metal shop class that we were assigned the task of getting a square base which had a round pipe welded to it centered up in a four-jaw chuck. I think it took me over 20 minutes to get that evil thing set up. Well done. Smooth, professional, and efficient.
A 4 jaw chuck is easy to use, its all about experience, you soon get used to it when using on a daily basis, creating deliberate run out on a 3 jaw chuck is harder.
I am a welder. I never had the opportunity to do any machining. It is fascinating to watch the tools work. I have to build tools and work through different set-ups too, it's great to watch you work through your tool build and set-ups.
i had an idea when you said that. clamp a stop block of some sort to the inside end of your calipers so that your calipers are as parallel as you can make them.
Re-educating myself after 35 years, your techniques are good common sense practice. I appreciate you showing little details like under cutting the soft metal under the carbide before sharpening the carbide bit. I especially liked the part where you explained and showed how to use a 4 jaw chuck and how to get the work piece running true before cutting. This is all stuff I kind of forgot about but you brought a lot back to me.
Thank you for sharing this! When I graduated high school in 1976 this is EXACTY what I wanted to do when I grew up, but as you know, sometimes life's journeys come with detours. My detour was a complete different map but hey, I can appreciate watching a true CRAFTSMAN at work and understand what it takes to do the job! You ROCK!
Between you and Tony I've learned a lot. It had been over 20 years since I ran an engine lathe but thanks to you and Tony I can confidently run one in my shop tool room.
I have zero experience with machining yet I find this absolutely fascinating. I would not have thought that you could support one end of that cylinder without it wobbling as it seems to be spinning true. In my one venture with a piece of mahogany and a friends table saw I managed to create toothpicks and jammed the wood bending his saw blade. Fortunately I did not cut any thing off of me. Anyone who can do this work deserves our highest regard.
You have a gift Adam; appealing to non-machinist, who like what you do and also your personality comes through with your delivery. We feel, you love what you do and love sharing it with us. Paul
Thank you for sharing your expertise. It used to be that skilled people would hide their skills so no one else could do it. I'm glad those days are gone. I just bought a Harbor Freight mini lathe about 2 months ago. I had not done any machining since High School in a general shop class that we did some very basic lathe work. That was 53 years ago. I am very pleased to see that many techniques that I have "figured out" are used here. Including rounding up the set up run out by tapping with a hammer.
On the 27th of August 2018 I start my training to become a novice machinist. I may never do the type of work you do but I sure hope I can be as professional.
hawkdaddy64 Hey. You’ll be fine. I started using a Herbert no 9c-30 (basically the same as this, maybe a tad bit bigger) when I was 16 and I just turned 17 a day ago. I’m a slow learner, but found it easy as I went along. Good luck with it.
Welcome to the trade, hawkdaddy! It was about three years ago, I watched my first machining video with Adam on that very machine working on a big hydraulic cylinder. I'm now completed my training, and having a blast working in a jobbing shop with a whole bunch of skilled guys. I'm not using any machines as big as this beast, but I did recently make a steel bushing with *tenths* tolerances inside and out, on a Lacfer lathe made in Spain, which is about half the size. In the end both diameters were dead-nuts on target, and the senior millwrights were impressed. My advice to you: watch a whole lotta TH-cam, and learn from these masters, and never ever stop learning.
@Travis Bickle Wow, I'm really sorry to hear about your injury, that totally sucks. I am finding my relationships with my co-workers get better all the time, and yes, they are all gold-mines of wisdom!
@Travis Bickle Sheesh - can't you get some accommodations to allow you to work again? Like a really good mobility scooter / exoskeleton etc.? Really sorry to hear you're missing out on the fun :'(
Man that brings me back. These videos are good for the soul. I ran many types of machines, internal and external grinders, centerless, mills, but my favorite was the Herbert 9C30 turret. Turned lots of cast on that baby.
I'm not a machinist but love watching the videos. Blows my mind that the cutters can mill cast iron at all, much less with the level of accuracy that they achieve. Mind blown.
Love watching these big parts turn on the lathe. So much so I went and bought me a bigger lathe and got my first taste of some real chip cutting last night. I just got me a Clausing 1500 and as of last night it is powered up and turning. It was only aluminum but I was cutting .200 (.400 total) off with HSSl and not a hint of struggle or chatter. Something my poor little Logan couldn't even dream of. Posting a video of getting the VFD attached now.
Its over 30 years since I last used one of these big lathes but every time I watch a movie like this I wish I could go and get my hands dirty on one... great stuff !
Very helpful to see your discipline in repeating measures and reversing the cast iron tube and getting precision. I enjoy and I learn your work - thanks.
I'm not gonna go crazy on it! Just dial in 0.150" on that great lump of cast with a 16" hangout. LOL Great job Adam. Thanks for sharing. Regards from the UK
This video is nothing short of fascinating. Your manipulation of the chuck to minimise run-out very educational and wow - what a massive piece of metal it is too!
I really enjoy your videos and maybe it has to do with the fact I worked in the steel fabrication and ornamental iron at the shop level for a couple years after high school. The steel company was a mindless job, but for an 18 year old it paid pretty well and enabled me to buy my first car. 85% of what I did all day was scrape rust off large I beams using a brush with steel bristles. It's a wonder I didn't come down with "rust cancer" later on. Working ornamental iron had more variety, but it wasn't my intent to stay in this trade as I was saving money to go to college, which I did after my stint in the Navy Reserves. Something about your work with iron, the information you pass on and the sounds of metal work are fascinating to me. Thanks for sharing and showing us your excellent skills and many of us know what you do is a lot more complicated than the way you present it. You are truly a craftsman.
I have worked on a manual lathe. This bring back old memories.i have also singled pointed threads. Now that was concentration. Then i worked on cnc machines.
@@attackonpieck2789 CNC machines are better, they have a higher precision and creating one or more pieces is much faster. What you prefer probably depends on if you prefer programming over this manual work. If you do it manually you can easily make errors.
OpenGL4ever I just went from a manual Herbert 9c-30 lathe to using a Mazak Smooth Nexus 250 CNC/Mill .. it is a massive jump. I enjoyed the manual lathe if I'm being honest, I'd put a cut on and be able to sit for a while, but because the cnc is so quick, I haven't got time to think lol.
@@OpenGL4ever OTOH you can crash a CNC machine, lose 2 days and $10K in repair and lost-production costs, just like that. Check everything, then CHECK EVERYTHING! :-)
@@RogerBarraud You can also crash a manual machine, lose 2 days and $10k in repair and lost-production costs but this is not what i meant with errors. The big difference is, with a CNC machine is, you can virtually test the run before you start the machine and human errors are very common on a manual machine. If you push the wheel 3 mm to far, you have machined to much away and you can't add the missing metal back to the workpiece. You have to restart from a fresh workpiece all over again. You lose time, money, materials that way and this can happen very often because it can easily happen. Crashing a CNC after the virtual test run is rather rare.
I’m a machinist and make complex aircraft & roto wing parts from prints; I m have no where near the skills you have brother and I learn something new ever-time I watch your show. I’m retired now but non the less. I love your show 😎

Adam's lathes really get a workout. I've done some lathe work on racing motorcycles (wheel spacers, axles etc...) but I've seen nothing compared to this man's machines and skills in operating them. It's mind blowing!
Worked for a major airline manufacturing company. I had college 5 years and had a hard time getting in. They had a machinist that I worked with for a short time. He said never went to high school and got in because you know. This Mans skills were beyond most people could hope for. He retired shortly after but He was revered by the company.
It's obvious you've been doing this for a decade or more. I hope your company was patient with you while you got to be this well versed in work habits. This was fun to watch as I did this for almost 2 years but never could get my company to let me develop. Too often companies want only the 20 year veterans for the lowest price and never let a new generation develop. I would have loved to have had you tutor me while I was learning. You just don't get this good in under five years. Keep up the great work. Thank You.
better to bend the handle than crack the spider gear or jaw screw.. The handle is a safety "fuse" against over zeallousness. I have a cheap cast iron chuck for my wood lathe that is basically scrap because the spider gear cracked through the key.
1st I want to thank you for showing how these things are done. I'm not in the industry, I'm a computer programmer in Boston. But I have a great appreciation for someone like you that skillfully makes something real and tangible in your daily work. Also liked the reference to Odessa. I lived in good old West Texas for a long time. Went to Nimitz and then Permian. Keep the well crafted videos coming.
"Lets put a little more radius on that Key!" - Love it. Thanks for sharing this stuff Abom, as a fitter/boilermaker who only gets to occasionally machine stuff, these vids are fascinating and invaluable.
I think i would be a little nervous with that big piece of iron hanging out there could you use a bull nose center on the tail stock just for insurance when turning the OD ?
Scott Lundy I'll be nervous if it was in a 3 jaw chuck, but his taking .150" a pass. It will handle that no problem, but for safety why not. If it was steel also a different story.
Scott Lundy I'm sure your not the only one. I've done many jobs like this so I'm not scared of it. I know will work and won't. As for the other comment about 3 material diameter stick out.... this one would have been well under that rule of thumb.
I’ve never watched such work. Very interesting. Damn impressed with the skill and talent required. It’s largely unknown and unappreciated by most Americans. My hat is off to you and others. Thanks.
I used to work in a small mom and pop machine shop when I was in High school. Doing grunt work and prep for about 6 years found it fascinating I just never pursued being a machinist as a career. Great video thanks
Cracks me up Adam, I just emailed you this week about the huge(2"dia. X 24" long) boring bar I acquired. I was thinking what brute is using that size boring bar. A few days later you are using the exact same size bar. You never cease to amaze me with the size of work you do. Much appreciated.
Going from 8.125" to 7.125" is not so bad, you can mill off another inch with time and effort. Now if the customer said, "I meant 8.25," WELL that's another matter entirely. Not so easy to put it back on!
Usually, the machinist has a blueprint to refer to so any mistakes in dimensions wouldn't be the lathe operators fault. Fun job Abom79. I used to run turret lathes back in the '70s and 80's. Eventually migrated to CNC lathes. Always was fun. Good memories watching you. Thanks bud!
@@tojo2774 from my experience, it's just annoying spending an hour making the dimensions perfect then the engineer comes back and says "oops the drawing was wrong, needs to be x dimension instead of y"
When I'm working on the lathe, 1/4 mile is plenty close enough lol. That stock has enough scale and beating on the surface that he was probably dead on.
Nice work Adam! I assume that was probably a class 35 or 40 gray iron based on the surface finish you achieved. However, the Foundry that cast that cylinder should be ashamed as the cored Inside diameter of that piece was Nasty!!! They should have ground that out and then blasted it prior to shipping it. As your probably aware, burn in and burn on sand will wipe out any type of insert.
i like the sound of the diamond going through my hears while i try to listen to your knowledge which i couldn't. i have a headache now and i know i should cover my hears while working one of those. that is knowledge right there. Thanks!

I don't know squat about machining, but like a kid who sits there watching heavy equipment move dirt, I find it fascinating to get a front row seat like this to watch Adam apply his amazing skills to create things. And not only does he keep his video camera aimed and focused to let me watch everything up close, but his communication skills are remarkably good, too. Even a dummy like me can understand what he's doing. I can't imagine how much money is sunk into that shop (his employer's), but it's gotta be a ton. Just look at the length of that lathe @ 20:50. It's longer than my car! Like many other novices here, you have me hooked, Adam!
got some tension with your coworkers? can't hear what he said but you felt a little annoyed.. great job, i'm actually trying to become machinist myself and it's mostly because of you (and AvE) thanks for the vid and the great work ;)
It's really not cool to be jabbering on when someone is trying to setup a work piece. The work does frequently get monotonous and people want some break but you can't be interfering with your co-workers. You have to show some discipline and save it for the lunch break or the bar after work.
I have a collague who loves to 'chew the fat' and always chooses a moment when I am hard at work and trying to concentrate. He never takes a hint - I have to be quite rude sometimes just to get him to move down the corridor to the next poor sod.
@@johnferguson7235 You are 100% correct on that point! Shut your mouth and let your co-worker finish his setup before jabbering on! I sent a bit right thru the mill table on a CNC mill, doing a job that required multiple bit changes during the program... Some moron was jabbering on at me, got me confused, and I put the wrong bit in for the step I was up to! Almost got ME fired until I explained why it happened! Machining is a DANGEROUS PROFESSION! It requires concentration and professionalism! So thanks for noting this, and I am happy to provide an example as to why it is true!
Usually squaring up the end of the bar to to Chuck so no need. He only uses a indicator at the Chuck because it's a 4 jaw and he has to close them individually. So you tighten down the jaws and make sure it's all even then square the end
Willie CTS - Cast iron is self lubricating - it has a high carbon content - think graphite in a pencil - I remember from 50 years ago - when you machine it on a fast speed the cuttings are a bit hot !!
Excellent job. Nowadays I manufactured similar bearing for water pump. Journal is from stainless steel, the surface is hardness to 55 HRC and the shell is form perlitic cast iron. Bearing is lubricated and cooled by water.
Adam, served my time as a Centre Lathe Turner (old school) at ICI Billingham on Teesside, England. Brilliant skills learnt, that using all these digital vernier gauges, much prefer to use calipers and a micro meter. Fantastic video of old school skills 👍
The old tool maker I learned the most from was Paul Pushee. The only tollroom lathe we had was a South Bend 13" that had been running 40 years and the time was in the early 80's. Paul said you have to know when to lead on the cross slide to make a true cylinder. It helped when I became Manufacturing Manager at Douglas Corporation. The machines were rebuilt junkers picked up at auction. The big lathes were monsters with up to 10 foot swkng and up to 30 foot beds. The guys running them were experts at holding their mouth right. 😆😎
+Abom79 When working on a stock as big as this, how do you account for heat expansion when measuring? In my manufacturing class, we have to cool off our workpieces before making a finishing cut so that it stays within tolerance. I'm usually working with aluminum round stock no bigger than 3" in diameter, so it's a different ballpark, but machining a 7" diameter piece of Cast iron must create a lot of heat.
If I had to guess, that much metal would work as a giant heat sink. So there wouldn't be that much heat or expansion anywhere other than where the bit is or just was. Plus by the time you get done making the first cut, the end where you started would have already cooled anyway! On top of that, that machine probably had some sort of dust collection going so there would have been a constant stream of fresh air getting to the piece. But I could be wrong, so I'll just point out that he stopped the video at a few points during which time he could have allowed it to cool. And he left the piece larger than he wanted by 1 one-thousandth before he polished it at the end so he might have been taking that expansion into account with his tolerances.
The heat is supposed to come off in the chips. Ideally, You would make this in an enclosed CNC lathe with high pressure coolant. The tolerances are dependent on the temp, but that is generally not an issue with high pressure coolant.
Very cool indeed. I get a kick out of watching machining in action from the rough metal to what goes into making the finished product. Well done and excellent details of the process.

When I was a little kid I used to haunt any construction site in town just to watch how things are done. Thanks for making me feel young again, and just like back then, I think I've learned something. Thank you again. J.
I'm working my butt off to afford a lathe and mill. I own a business so time and money are in short supply. I've learned so much academically from you and others on TH-cam like you, Adam. And a fellow Florida boy at that! Can't wait to start applying the theory I'm absorbing into skill building and practice.
If they're going to be for production pieces, then you should lease for a coupla yrs and make the money from the equipment to pay and buy out the lease. You should be able to write off running expenses while leasing and write off wear and tear after purchase.
I know a guy who bought a small lathe and small mill (both manual) from an auction and already had a small contract for simple parts in good quantities. He hired a machine operator to make the parts and made enough money in 6 months to start buying decent CNC machines and to hire a CNC machinist. Now, he owns big.
Close to midnight here in Germany, time for watching Adam cutting some metal.
Ich hätte es anders gemacht.

I never tire of watching you at work on these great old machines!
I had the great good fortune to have worked at Lawrence Livermore National Labs back in the 1970’s and 1980’s, learning to make chips on all the old machines - most from WWII, but rebuilt by their in house mechanics.
Watching these old craftsmen scrape the ways, and make those old lathes, mills, etc. come back to life was a real education for me as a beginning machinist.
Today, nearly 40 years later, I miss the smell of the coolant, the smell of those raw materials, the feel of the tools in my hands, the moment of victory when I first learned to single point threads after grinding the thread cutting tool bit.
The joy of knowing you can literally make ANYTHING of metals, machinable ceramics, and plastics, and even wood when necessary is just great!
So, I appreciate your skills and your fearlessness to take on any job and get it done in fine style.
As a hobby machinist, I really enjoy watching an experienced pro. No wasted motions, no wasted time, no wasted material. Well done, sir, well done.
I'm not a machinist, but I do enjoy watching the process and the way you do things is very calming and enjoyable aside from being accurate and precise. I hope the company you work for understands what an asset they have in you. I know that the TH-cam community certainly does. Keep up the impressive work!
Really enjoyed your video! Reminds me of the times I would bring a dinner to my dad while he worked at a tool and die company. So enjoyed watching my dad work lathes and milling machines! He was a stickler for accuracy as you demonstrated in this video.
Please continue to put these videos out there so people can grasp how things are made.
Brings back so many memories from my dad who was a machinist, he bough a small table top lathe after he retired and started teaching me but got sick and passed before he could teach me much. So much talent lost from his death. You are a true craftsman sir. Thanks for the memories.
...that's sad.
Bravo ! Great to see a guy using an old machine tool to make a useful product. Wish my father was still around to see this. He would have enjoyed your skill as much as I do.
A working man with skills... Very cool and humbling to watch.
Adam, you make using that four jaw chuck look way too easy!
Very true. I remember in high school metal shop class that we were assigned the task of getting a square base which had a round pipe welded to it centered up in a four-jaw chuck. I think it took me over 20 minutes to get that evil thing set up. Well done. Smooth, professional, and efficient.
it is easy.
A 4 jaw chuck is easy to use, its all about experience, you soon get used to it when using on a daily basis, creating deliberate run out on a 3 jaw chuck is harder.
Prefer 4 jaw over 3 any day you can dial it in easier
I am a home shop machinist so I'm amazed to see a large lathe machining a large part. There is always something to learn. Thanks for your videos.
I am a welder. I never had the opportunity to do any machining. It is fascinating to watch the tools work. I have to build tools and work through different set-ups too, it's great to watch you work through your tool build and set-ups.
I watched the whole thing, it's great to see something made and as an artist I can't say how much I admire your skills.
"So, how you gona measure the end length? Good question, I don't know either." That one gave me a good laugh. Thanks Adam
I really appreciated that too, Adam. I chuckled out loud.
Daniel Kruger I was hoping to get some ideas, but I couldn't wait around.
i had an idea when you said that. clamp a stop block of some sort to the inside end of your calipers so that your calipers are as parallel as you can make them.
Re-educating myself after 35 years, your techniques are good common sense practice. I appreciate you showing little details like under cutting the soft metal under the carbide before sharpening the carbide bit. I especially liked the part where you explained and showed how to use a 4 jaw chuck and how to get the work piece running true before cutting. This is all stuff I kind of forgot about but you brought a lot back to me.
Thank you for sharing this! When I graduated high school in 1976 this is EXACTY what I wanted to do when I grew up, but as you know, sometimes life's journeys come with detours. My detour was a complete different map but hey, I can appreciate watching a true CRAFTSMAN at work and understand what it takes to do the job! You ROCK!
Don’t know what it is but I could watch you do these all day long, good job, and your damn good at it sir 👍
A great big bearing. A shaft will go through the hole in the middle
Another Saturday Evening and another Sns video to watch while tinkering. Really a wonderful ritual!
Between you and Tony I've learned a lot. It had been over 20 years since I ran an engine lathe but thanks to you and Tony I can confidently run one in my shop tool room.
I have zero experience with machining yet I find this absolutely fascinating. I would not have thought that you could support one end of that cylinder without it wobbling as it seems to be spinning true. In my one venture with a piece of mahogany and a friends table saw I managed to create toothpicks and jammed the wood bending his saw blade. Fortunately I did not cut any thing off of me. Anyone who can do this work deserves our highest regard.
Adam i wish you were my mentor, i would love to learn everything from you, great video once again, Thanks.
Adam : you do a hell of a good job my friend . A Job well done , thanks for share it with us .
You have a gift Adam; appealing to non-machinist, who like what you do and also your personality comes through with your delivery. We feel, you love what you do and love sharing it with us. Paul
Clever, safe, and precise. That is what I observe in every one of your videos. Thanks!
I call the caliper "very near"
Just love your passion and gift of giving to everyone your knowledge.
"I think I might need a little bit bigger hammer." Famous words from ANYBODY that works with their hands!!
Same phrase that I used in the Plumbers and Pipefitters union in the 70's and 80's, after the Army. BFH Big Freaking Hammer!
Thank you for sharing your expertise. It used to be that skilled people would hide their skills so no one else could do it. I'm glad those days are gone.
I just bought a Harbor Freight mini lathe about 2 months ago. I had not done any machining since High School in a general shop class that we did some very basic lathe work. That was 53 years ago. I am very pleased to see that many techniques that I have "figured out" are used here. Including rounding up the set up run out by tapping with a hammer.
I never tire of watching you indicate a piece. It is remarkable to me.
On the 27th of August 2018 I start my training to become a novice machinist. I may never do the type of work you do but I sure hope I can be as professional.
Awesome! 👍🏻
hawkdaddy64 Hey. You’ll be fine. I started using a Herbert no 9c-30 (basically the same as this, maybe a tad bit bigger) when I was 16 and I just turned 17 a day ago. I’m a slow learner, but found it easy as I went along. Good luck with it.
Welcome to the trade, hawkdaddy! It was about three years ago, I watched my first machining video with Adam on that very machine working on a big hydraulic cylinder. I'm now completed my training, and having a blast working in a jobbing shop with a whole bunch of skilled guys. I'm not using any machines as big as this beast, but I did recently make a steel bushing with *tenths* tolerances inside and out, on a Lacfer lathe made in Spain, which is about half the size. In the end both diameters were dead-nuts on target, and the senior millwrights were impressed. My advice to you: watch a whole lotta TH-cam, and learn from these masters, and never ever stop learning.
@Travis Bickle Wow, I'm really sorry to hear about your injury, that totally sucks. I am finding my relationships with my co-workers get better all the time, and yes, they are all gold-mines of wisdom!
@Travis Bickle Sheesh - can't you get some accommodations to allow you to work again? Like a really good mobility scooter / exoskeleton etc.?
Really sorry to hear you're missing out on the fun :'(
"You guys can take a breath now." [mounts steadyrest]. Ha! You really know what your audience is thinking Adam!
davecc0000 can’t see it from my house either
Man that brings me back. These videos are good for the soul. I ran many types of machines, internal and external grinders, centerless, mills, but my favorite was the Herbert 9C30 turret. Turned lots of cast on that baby.
I'm not a machinist but love watching the videos. Blows my mind that the cutters can mill cast iron at all, much less with the level of accuracy that they achieve. Mind blown.
26:51 Damn, that indicator didn't even move. I'm impressed.
Love watching these big parts turn on the lathe. So much so I went and bought me a bigger lathe and got my first taste of some real chip cutting last night. I just got me a Clausing 1500 and as of last night it is powered up and turning. It was only aluminum but I was cutting .200 (.400 total) off with HSSl and not a hint of struggle or chatter. Something my poor little Logan couldn't even dream of. Posting a video of getting the VFD attached now.
Its over 30 years since I last used one of these big lathes but every time I watch a movie like this I wish I could go and get my hands dirty on one... great stuff !
Very helpful to see your discipline in repeating measures and reversing the cast iron tube and getting precision. I enjoy and I learn your work - thanks.
I'm not gonna go crazy on it! Just dial in 0.150" on that great lump of cast with a 16" hangout. LOL Great job Adam. Thanks for sharing. Regards from the UK
Heck yea trust me your don't want to stand there in front of the machine all day. Sometimes u get impatient
A cup of coffee and these videoes are saving me from going insane doing Covid-19.
This video is nothing short of fascinating. Your manipulation of the chuck to minimise run-out very educational and wow - what a massive piece of metal it is too!
I really enjoy your videos and maybe it has to do with the fact I worked in the steel fabrication and ornamental iron at the shop level for a couple years after high school. The steel company was a mindless job, but for an 18 year old it paid pretty well and enabled me to buy my first car. 85% of what I did all day was scrape rust off large I beams using a brush with steel bristles. It's a wonder I didn't come down with "rust cancer" later on. Working ornamental iron had more variety, but it wasn't my intent to stay in this trade as I was saving money to go to college, which I did after my stint in the Navy Reserves.
Something about your work with iron, the information you pass on and the sounds of metal work are fascinating to me. Thanks for sharing and showing us your excellent skills and many of us know what you do is a lot more complicated than the way you present it. You are truly a craftsman.
I have worked on a manual lathe. This bring back old memories.i have also singled pointed threads. Now that was concentration. Then i worked on cnc machines.
Robert Chavez Do you prefer using CNC machines to manual lathes?
@@attackonpieck2789
CNC machines are better, they have a higher precision and creating one or more pieces is much faster. What you prefer probably depends on if you prefer programming over this manual work. If you do it manually you can easily make errors.
OpenGL4ever I just went from a manual Herbert 9c-30 lathe to using a Mazak Smooth Nexus 250 CNC/Mill .. it is a massive jump. I enjoyed the manual lathe if I'm being honest, I'd put a cut on and be able to sit for a while, but because the cnc is so quick, I haven't got time to think lol.
@@OpenGL4ever OTOH you can crash a CNC machine, lose 2 days and $10K in repair and lost-production costs, just like that.
Check everything, then CHECK EVERYTHING!
:-)
@@RogerBarraud
You can also crash a manual machine, lose 2 days and $10k in repair and lost-production costs but this is not what i meant with errors.
The big difference is, with a CNC machine is, you can virtually test the run before you start the machine and human errors are very common on a manual machine. If you push the wheel 3 mm to far, you have machined to much away and you can't add the missing metal back to the workpiece. You have to restart from a fresh workpiece all over again. You lose time, money, materials that way and this can happen very often because it can easily happen. Crashing a CNC after the virtual test run is rather rare.
I was all set for an Abom-sized parting tool, then seeing Adam catch that little bushing with his index finger.
You sir do an exquisite job of explaining everything as well as showing all the tips & tricks! Very well done!
The short, simple comments you make took years. Love this channel. Got it from a friend today. Heaven on earth. Thank you. raphael santore
Nice job again Adam.
You had a lot of cleaning and oiling to do afterwards.
I like that indicator friction pad!!
I’m a machinist and make complex aircraft & roto wing parts from prints; I m have no where near the skills you have brother and I learn something new ever-time I watch your show. I’m retired now but non the less. I love your show 😎
Been a machinist for about 5 years now, both manual and cnc, rather do manual though, and you do incredible work, good job man
"That's within a quarter mile...." a little machinist humor there.
"Thats within a quarter mile" I like that lmao

Adam's lathes really get a workout. I've done some lathe work on racing motorcycles (wheel spacers, axles etc...) but I've seen nothing compared to this man's machines and skills in operating them. It's mind blowing!
Worked for a major airline manufacturing company. I had college 5 years and had a hard time getting in. They had a machinist that I worked with for a short time. He said never went to high school and got in because you know. This Mans skills were beyond most people could hope for. He retired shortly after but He was revered by the company.
Fascinating
working with the inaccuracy's of the machine to get an accurate part. Love it ( 9:30)
you've no idea how helpful your videos are to people who watch them the way through and can apply what your saying.
Story of my life 😂
It's obvious you've been doing this for a decade or more. I hope your company was patient with you while you got to be this well versed in work habits. This was fun to watch as I did this for almost 2 years but never could get my company to let me develop. Too often companies want only the 20 year veterans for the lowest price and never let a new generation develop. I would have loved to have had you tutor me while I was learning. You just don't get this good in under five years. Keep up the great work. Thank You.
Beautiful bro. I've not worked in a machine shop in over 30 years. That was fun to watch and brings back some fond memories. Thanks!
Thank you for that live center, at last. I was starting to sweat.
Just put a lil more radius on the chuck key. Lol.
Now there is a good project an Abom Proof Chuck Key, just don't let Tom Lipton make it.
better to bend the handle than crack the spider gear or jaw screw.. The handle is a safety "fuse" against over zeallousness. I have a cheap cast iron chuck for my wood lathe that is basically scrap because the spider gear cracked through the key.
justin2221 That handle is a soft piece of Bar stock, not hardened or heat treated. Your going to hurt that Cushman chuck.
i found it amusing hehe
John Bare+ I was just about to link to the video before I realised who Tom Lipton is, lol.
1st I want to thank you for showing how these things are done. I'm not in the industry, I'm a computer programmer in Boston. But I have a great appreciation for someone like you that skillfully makes something real and tangible in your daily work. Also liked the reference to Odessa. I lived in good old West Texas for a long time. Went to Nimitz and then Permian. Keep the well crafted videos coming.
"Lets put a little more radius on that Key!" - Love it.
Thanks for sharing this stuff Abom, as a fitter/boilermaker who only gets to occasionally machine stuff, these vids
are fascinating and invaluable.
I think i would be a little nervous with that big piece of iron hanging out there could you use a bull nose center on the tail stock just for insurance when turning the OD ?
Scott Lundy I'll be nervous if it was in a 3 jaw chuck, but his taking .150" a pass. It will handle that no problem, but for safety why not. If it was steel also a different story.
My tech school instructors were absolute about no more than 3 material diameters sticking out of the chuck. More than that, had to be supported.
Scott Lundy I'm sure your not the only one. I've done many jobs like this so I'm not scared of it. I know will work and won't.
As for the other comment about 3 material diameter stick out.... this one would have been well under that rule of thumb.
19" Part length / 3 = 6. 333". Final diameter was over 8". Plenty of space.
I've done stuff bigger with no tail support as long as its chucked tight enough and indicated fairly close it's not that big of a deal.
I love it. "We're not taking big cuts, just some moderate ones. Maybe 100 thou." Lol my mini lathe begs me to stop at 15 thou
I’ve never watched such work. Very interesting. Damn impressed with the skill and talent required. It’s largely unknown and unappreciated by most Americans. My hat is off to you and others. Thanks.
I used to work in a small mom and pop machine shop when I was in High school. Doing grunt work and prep for about 6 years found it fascinating I just never pursued being a machinist as a career. Great video thanks
Cracks me up Adam, I just emailed you this week about the huge(2"dia. X 24" long) boring bar I acquired. I was thinking what brute is using that size boring bar. A few days later you are using the exact same size bar. You never cease to amaze me with the size of work you do. Much appreciated.
grntitan1 Yep, I love that 2" Aloris bar!
@@Abom79 you are the shop teacher I wish I had
Customer comes back.... "oh, did I say 8.125"? I meant 7.125", my bad"
iforce2d Fancy seeing you here!
Going from 8.125" to 7.125" is not so bad, you can mill off another inch with time and effort. Now if the customer said, "I meant 8.25," WELL that's another matter entirely. Not so easy to put it back on!
Usually, the machinist has a blueprint to refer to so any mistakes in dimensions wouldn't be the lathe operators fault. Fun job Abom79. I used to run turret lathes back in the '70s and 80's. Eventually migrated to CNC lathes. Always was fun. Good memories watching you. Thanks bud!
@Mujaki No problems. Just run the lathe backwards.
@@tojo2774 from my experience, it's just annoying spending an hour making the dimensions perfect then the engineer comes back and says "oops the drawing was wrong, needs to be x dimension instead of y"
Adam is a great tutor for all the apprentices out there. Keep up the great work mate.
I like to watch your videos because you're a true professional machinist. Your techniques are the real deal.
lol i love it. thats within a quarter mile, there anit nothing wrong with that... lol
.
Never seen a dial indicator that measures in quarter miles, lol
Mile, or mil?
When I'm working on the lathe, 1/4 mile is plenty close enough lol. That stock has enough scale and beating on the surface that he was probably dead on.
what is that bearing for?.....a tank?.....earth mover?..... production machinery of some sort?..... it probably cost more than a decent used car.
Where I work they make bearings as big as a small dog house. The bear metal costs as much as a luxury vehicle.
@@thothheartmaat2833 I'm pretty sure bear metal is on the endangered alloys list, only available on the black market.
@@silasdogwood8395 you can get it from Russia on the cheap..
Nice work Adam! I assume that was probably a class 35 or 40 gray iron based on the surface finish you achieved. However, the Foundry that cast that cylinder should be ashamed as the cored Inside diameter of that piece was Nasty!!! They should have ground that out and then blasted it prior to shipping it. As your probably aware, burn in and burn on sand will wipe out any type of insert.
i like the sound of the diamond going through my hears while i try to listen to your knowledge which i couldn't. i have a headache now and i know i should cover my hears while working one of those.
that is knowledge right there. Thanks!

I don't know squat about machining, but like a kid who sits there watching heavy equipment move dirt, I find it fascinating to get a front row seat like this to watch Adam apply his amazing skills to create things. And not only does he keep his video camera aimed and focused to let me watch everything up close, but his communication skills are remarkably good, too. Even a dummy like me can understand what he's doing. I can't imagine how much money is sunk into that shop (his employer's), but it's gotta be a ton. Just look at the length of that lathe @ 20:50. It's longer than my car! Like many other novices here, you have me hooked, Adam!
got some tension with your coworkers? can't hear what he said but you felt a little annoyed..
great job, i'm actually trying to become machinist myself and it's mostly because of you (and AvE)
thanks for the vid and the great work ;)
It's really not cool to be jabbering on when someone is trying to setup a work piece. The work does frequently get monotonous and people want some break but you can't be interfering with your co-workers. You have to show some discipline and save it for the lunch break or the bar after work.
zer0toto I think that is just his concentration. it can be difficult to maintain focus while someone is chattering next to you.
well as not talkin to someone actually doin somethin was part of his work etiquette rules, i assumed it culd be, but you're probably right :)
I have a collague who loves to 'chew the fat' and always chooses a moment when I am hard at work and trying to concentrate. He never takes a hint - I have to be quite rude sometimes just to get him to move down the corridor to the next poor sod.
@@johnferguson7235 You are 100% correct on that point! Shut your mouth and let your co-worker finish his setup before jabbering on! I sent a bit right thru the mill table on a CNC mill, doing a job that required multiple bit changes during the program... Some moron was jabbering on at me, got me confused, and I put the wrong bit in for the step I was up to! Almost got ME fired until I explained why it happened! Machining is a DANGEROUS PROFESSION! It requires concentration and professionalism! So thanks for noting this, and I am happy to provide an example as to why it is true!
Why you don't use two indicators at the beginning and at the end of material ?
now thats a good question... maybe they only have one for that particular set up?
ROI == ???
Probably quicker than the Boss thinks :-)
Usually squaring up the end of the bar to to Chuck so no need. He only uses a indicator at the Chuck because it's a 4 jaw and he has to close them individually. So you tighten down the jaws and make sure it's all even then square the end
Amazing skill. I tip my hat to you. Machining like that is like an art form
I have nothing to do with machining metal but it is a genuine pleasure to watch a craftsman at work.
Why isn't it liquid cooled or lubricated? Would make your bits last longer.
I was wondering that right away! Especially with cast, while relatively soft, is nasty stuff! I wouldn't want to be inhaling the dust!
Willie CTS - Cast iron is self lubricating - it has a high carbon content - think graphite in a pencil - I remember from 50 years ago - when you machine it on a fast speed the cuttings are a bit hot !!
I think Abom needs a bigger chuck wrench, get rid of those bent bars. It obviously not upto Abom torque. LOL
Excellent job. Nowadays I manufactured similar bearing for water pump. Journal is from stainless steel, the surface is hardness to 55 HRC and the shell is form perlitic cast iron. Bearing is lubricated and cooled by water.
Adam, served my time as a Centre Lathe Turner (old school) at ICI Billingham on Teesside, England. Brilliant skills learnt, that using all these digital vernier gauges, much prefer to use calipers and a micro meter. Fantastic video of old school skills 👍
Thats with in a 1/4 mile! That was funny Abom, im going to use that one.
thank you for your video
The old tool maker I learned the most from was Paul Pushee. The only tollroom lathe we had was a South Bend 13" that had been running 40 years and the time was in the early 80's.
Paul said you have to know when to lead on the cross slide to make a true cylinder.
It helped when I became Manufacturing Manager at Douglas Corporation. The machines were rebuilt junkers picked up at auction. The big lathes were monsters with up to 10 foot swkng and up to 30 foot beds. The guys running them were experts at holding their mouth right. 😆😎
+Abom79 When working on a stock as big as this, how do you account for heat expansion when measuring? In my manufacturing class, we have to cool off our workpieces before making a finishing cut so that it stays within tolerance. I'm usually working with aluminum round stock no bigger than 3" in diameter, so it's a different ballpark, but machining a 7" diameter piece of Cast iron must create a lot of heat.
Ya let it cool right down bud
If I had to guess, that much metal would work as a giant heat sink. So there wouldn't be that much heat or expansion anywhere other than where the bit is or just was. Plus by the time you get done making the first cut, the end where you started would have already cooled anyway! On top of that, that machine probably had some sort of dust collection going so there would have been a constant stream of fresh air getting to the piece.
But I could be wrong, so I'll just point out that he stopped the video at a few points during which time he could have allowed it to cool. And he left the piece larger than he wanted by 1 one-thousandth before he polished it at the end so he might have been taking that expansion into account with his tolerances.
The heat is supposed to come off in the chips. Ideally, You would make this in an enclosed CNC lathe with high pressure coolant. The tolerances are dependent on the temp, but that is generally not an issue with high pressure coolant.
sssbob The temp variant is the reason for the tolerances. In a perfect world, all
Machining would be done in a 20degC environment with 35% humidity.
@@Hypercube9 I'd agree with that, the surface area to mass ratio on something this big probably means it doesn't get that hot anyway
Seriously entertaining Abom.....Thanx
I used to machine stuff like this for a living 20 years ago, sometimes I kind of miss it...so thank you for for uploading
Very cool indeed. I get a kick out of watching machining in action from the rough metal to what goes into making the finished product. Well done and excellent details of the process.
Love your new intro music!
