To you negative people, Video was made over 25 years ago. So the resolution is the norm for those days. And about everything else this gentleman is doing this on his own for free. Be grateful. He is helping a lot of people who are beginners. Most students go straight to CNC and never learn to use a manual lathe.
Err, the whole "an MIT production" at the beginning rules out "his own time."
no one's complaining - great series and well done - good quality for a VHS transfer
@@thegardenofeatin5965 not exactly, he chose to wake up that morning and go to the filming, he could have just stayed home
Yup. That's a long time ago. Be grateful our standards have changed. My phone.. no make that my last 3 phones record better video and cnc has turned this obsolete.
You honestly do not need great resolution to see what he is teaching.
My grandfather was a machinist at the atlanta steel mill, then for ajc until he retired. He has a full machine shop but sadly i was an uninterested child when he was alive. Many years have gone by since his passing and at this point in my life and career i have a burning passion to learn as much as i can on the tools he has. i find myself longing to ask for his advise and knowledge. It is a very frustrating situation knowing he is right there in the barn with me in spirit, but i can't physically seek his advise.
Dang... its okay bro your grandfather is probably happy knowing you love machines now.
He's that voice that comes to you in difficult situations, he's that feeling you get when you figure out an easier way to do your task. And he is that inspiration and desire you now have to learn more.
@@xrpkidotec520No those are familiar spirits aka demons. Once you die you either go to be with the Lord or without Him in hell.
The Lord Jesus Christ died for your sins, was buried and rose from the dead on the 3rd day according to the scriptures (The Gospel 1 Corinthians 15:1-4). If you believe in your heart that God rose Jesus Christ from the dead and confess with your mouth Jesus Christ is The Lord you will be saved (Romans 10) Go to a quiet place and ask the Lord to save you and forgive you from your sins - Believe on Jesus Christ and call out to Him before it's too late
I hope he was a man of faith in Christ - if so he's in absolute rest and peace - if not then we must learn from his mistake and be careful not to make them ourselves
An excellent lesson to those who still have talented, insightful, skillful, and/or knowledgeable parents and grandparents.
They are not burdens. They are blessings. Act accordingly.

thank!
Your so helpful, thank you.
thank you
This is a great video for someone who knows almost nothing about lathes and wants to get an idea of the basic operations. Thank you for posting it!
This video was the perfect introduction to using a metalwork lathe for a complete novice. Thank you for such a clear and well paced explanation. Any negative comments must be from people who were not the target audience. Love this video, it has given me the confidence to start with metalworking.
The best lathe tutorial which I have seen so far. Excellent instructions, very clearly spoken and in the right pace for beginners. Thank you very much for working ambitiously on creating such a fabulous video. Super great job!
I live in thailand . I study many skills from yours. Thankyou verymuch for your kindness to make these education.
akuan on - UC Berkeley also has online courses in shop safety and operations. Enough different to warrant watching.
I can't believe these idiots are botching because of the quality GESH. Thank you for uploading such high quality video
I have learned so much from these MIT videos. Clear, concise, and perfect for a beginner.
This series is by far the best lathe basics tutorial I've yet to find on the RUclipss. Great jerb!
What I really appreciate in this video is how the host emphasizes safety points like trurning the chuck with a hand before starting the motor. There are many more other good points as well that I haven't seen in other sililar tutorials. Of course the contents is general but it's a good starter method.
Excellent instruction video especially for a beginners who I am sure will greatly benefit from watching this video. I myself am very new to metal lathes or engineering lathes so have found this video very helpful. The narrator or person giving the instruction in this video is just great, he describes each section of the lathe in such a manner that you feel confident that you know the basics, thank you so much for taking the time and energy to produce this video !
I love how he puts it, "just to make sure nothing exciting happens"..lol
We had an old saying in the shops I worked in, which had a particularly important message: DON'T get "wrapped up" in your work.
A tip for centering your cutting to to the center of the part:
Instead of "eyeballing" the cutting edge to the center of the end of the part, use a 6" metal scale, and suspend it at about the 3" mark between the cutting tool and a part OD diameter. Move the cross slide just enough to "pinch" the scale between the cutting edge and the work piece OD.
Adjust the tool height until the scale is "vertical", and you will have your tool on center.
If the scale is tilted, at the upper end, away from the machinist, the tool is too high.
Visa versa if the upper end of the scale is tilting toward the machinist.
You will have to make a video. This method can be very helpful and will especially be very simple to use on a quick change tool post.
been studying you videos, finally got the promotion at the shop. a million thanks to you.
Excellent tutorial. I haven't used a lathe in a long time and this is a good refresher. Also very interesting. Thank you.
Great video, packed full of info, well filmed. If only all instructional videos could be this good.
I was looking for a simple yet detailed video tutorial, thanks man...
Went to a vocational high school for Machine Tool. Hated every minute of it. Now, looking back over thirty years, I'm amazed how much I remember. I can smell this video. Especially when the cut starts.
Thanks a lot for these videos. They are much appreciated on many levels.
Perfect for the beginner! Clear and concise explanations, emphasis on lathe safety, and really helpful advise on alternative ways of doing various procedures.
I,m looking for job.
for this job i have 20years experieance in middle east,
I learned how to cut long ways with my dad's lathe for the first time last night made my very first piece feel pretty excited about it
Had an old machinists tell also when you're breaking the edge, make sure you hold the file so if the part grabs the file, it pulls it away from you. He said he a lot of machinists hold it were it throws it into to you
The question for the day is why didn’t I start here first. Amazing simple and concise instruction for we beginners. ty for posting this.
This is a good video for those who have just bought their first lathe....thank you.
Thanks for a very well produced tutorial.
I worked in a machine shop for 40 years,made all sorts of things in the lathe,bridgeport,grinders,I loved it,and miss it.
Thanks for the free lesson I appreciate it.
Please watch also basic machining thank you ruclips.net/video/VTwtFjwyZQE/видео.html
I know this is an old video, but i just picked up a 1924 south bend 9" for very little, single owner machine that ended up being excellent. Im just "show and tell"ing, but an all original machine at nearly 100yrs old getting back to work makes me happy
great info and thanks for taking the time to do the video. I will watch parts 2 n 3 next.
this is a REALLY well done series! kudos
Thanks for posting. It is a nice companion film to South Bend's "How To Run A Lathe" (also on RUclips).
Been looking for a video like this. My work has an old lathe that hasnt seen use in a while. Cleaning it up on my breaks and hopefully will get it turning soon. Then we can stop outsourcing external thread cutting. Thanks!
Well done for making this video, very educational, thanks!
I am newbie to lath operation and have watched many videos, this one is the best in terms of safety advise, clear speaking language, basic late operation tips. Seems like from MIT ?. Thanks for good educational videos for the public.
Very well done! Thank you.
Very informative. I start my first lathe job tomorrow. This will come in handy
I know its an older video, but damn I would really love to see the details to learn. It would help immensely. Because this is one of the best instructional videos I've seen so far.
awesome introduction on lathe
THANK YOU SO MUCH
Thank you so much for such a helpful and comprehensive tutorial...as a welder and fabricator this video is a revelation! GREAT JOB!
A word to the wise... NEVER remove metal chip strings by hand! You can make a chip hook with a threaded wooden file handle and a piece of hot rolled or cold rod about a foot or so long. Bend a small hook on the end and thread the straight end into the file handle. You can also use needle nose pliers to pull on stubborn chips. And I repeat... NEVER try to remove metal chips by hand!
...Right...Never....!
i tried when i'am still a beginner. its quite hot and sharp. its really dangerous
This is an excellent video. Thank you for sharing. I'm going to be trying to use a lathe. The knowledge shared here is professional. If you have any similar videos, please share them if you could. Thanks again for sharing.
That's a really nice lathe!
Thanks a lot for posting. I was looking a video like this.
Very informative, wish I could see an updated video of this in High Def
You know the feeling when you find a favorite new channel or series or show... Yeah, this is my new favorite
Excellent video, very helpful to those of us who are beginners
Great video, thanks ! And, that's a great lathe too, a Monarch EE I believe.
Thank you for your lessons. I like machining Mechanics
"This cutting tool is angled so that the chips come off really nicely"
*proceeds to make one gigantic, continuous chip on a roughing pass*
Continuous chips can be very dangerous. I speak from experience, having worked in several machine shops for over twenty years before retiring. Most new cutting tools have indexable throwaway inserts that have multiple cutting edges and built in chip breakers. The old carbide tools that have brazed on carbide cutting edges were top and side ground, either with positive, negative or neutral rake angles and a particular radius on the cutting corner. Typical radii on standard lathe cutting inserts are 1/64" (.015625"), 1/32" (.03125"), 3/64" (.046875"), 1/16" (.0625") and 1/8" (.125"). Of course, radii can be made to order for any given application. The previously mentioned radii are generally referred to in machine shops as .015", .030", .045", .060" and .125". With new N/C lathes, it is very common for a particular radius to be machined with a cutting tool with a smaller radius, making it particularly advantageous during machining, since multiple and various size radii can be machined with one cutting tool using a particular radius insert. A good rule to remember is for a given federate and surface speed, the larger the tool nose radius, the better the workpiece surface finish.
Yeah either tool wasn't sharp or feed rate not right.
thanks! Just got my 1st lathe, a 9 south bend. im 41 and a boat mechanic and always been a little fascinated by the ordinariness of (lathes for example).. I needed to buy the lantern style, for the most part ill be doing 1-2" round cuts.. starter motor shafts and commutators for example. What cutters / angles should I use as a general rule? is there a chart somewhere? its a little confusing to me. I did 2 electric motors on a 40's black and decker valve grinder i refurbished - came out within 2/10000 - despite me clamping a badly made HSS tool on the compound with a c-clamp!
To be fair, I don't remember people talking much about chip breakers back in the day. The interwebs have greatly increased the speed at which ideas spread!
Great video series -- thanks for posting it!
I was always envious that students at MIT could use the machine tools themselves. I got my engineering degree at the University of Illinois. We weren't allowed to use the tools -- had to make blueprints and give those to the union machinists in the basement shop for "safety reasons". The end result is a bunch of graduates who are awesome with calculus, but don't know the first thing about actually building anything. Fortunately I had good experiences in high school and have acquired lots of equipment in the years since.
IlliniRob1
IlliniRob1 I am surprise MIT allowed machine tool use. I worked with more than a few Mechanical Engineers, Electrical Engineers, Civil Engineers, etc. who were excellent to adequate with the numbers, but they could barely change a light bulb when it came to hands on. The best engineers I worked will were usually out of the UK, or Europe. I have seen a lot of FUBAR drawings from Mechanical Engineers, who never used a machine tool on their life, and you would have to spend extra time trying to reference a measurement from some god awful blind hole or other equally inaccessible place. Had they spent some time machining hands-on they would know not to do that goofy stuff.
+Seth B
There are a lot of engineers like that. Engineering gets two kinds of people. Those who design, and don't know how to build anything. Then there are those who's whole life is building things. I didn't go to MIT, I went to OU. But most of my engineering class were those people who built things. We could weld, we could machine, we could build actual things out of either metal or wood (and some could cast metals... I didn't understand that part). The reason we went to school in engineering is that we wanted to understand how to design what we want to build, and how things work so that we can design things that work correctly, and hold up correctly. For most of my life, I have been building things... and most engineers are that way. And frankly, most of actual real world stuff is learned on the job. If the folks are referencing inaccessible places for measurements, your company should be educating them on what is an actual good place to reference from... like a center pin, or an alignment pin (probably a pair) or some such.
15:00 Had a fellow student 30 years ago almost lose a finger by those metal chips.
He pinched them with his fingers as the machine worked. it wrapped around the part he was working and around his finger. Cut almost down to the bone before the chips split apart.
Very helpful with a clear explination. Would have loved to get more info on setting feeds and speeds.
Very helpful. Vocab has always been my downfall, so thanks for explaining everything! Points for keeping me safe as well.
Great basic instructions, thank you.
Excellent Video and excellent precise instructor.
As always, thanks’ for taking the time to make this video! And I support this site. ~M~
Aw yes. Takes me back to shop class in High School. I still have a Stanley Cup I've made on an engine Lathe.
Very informative you explain everything in detail .. Thank you
Excellent Video ! Thank You !
Thank-you for the video, very educational
U make best educational videos! I wish you success!
Lots of great tips, very helpful. It's a shame the video and lighting are not so good, but it's still a great intro. I may as well learn the best techniques at the start. Many Thanks.
I gotten alot out of this. Thank you
very informative thanks for posting
Never say you have boring tools. I find them all interesting.
Very informative. Good work. Thanx :)
You are excellent instructo to clear teching about mAchine shop.
Resolution = Poor, Content quality= Amazing! thank you.
Excellent video for me, as ism looking to purchase an older lathe an learn what I can do with it
Very informative
The best video for metal turning LEVEL 1 UK. This will make you pass if you follow this. (without the file for breaking the edge) Excellent video
Thank's for the info., especially the details about which angle(s) are required (at the compound) to do which types of work/cutting, facing etc. Only wished the film was a bit more focused/ clearer and that I could have seen some more close-ups of the really important areas, kind of reminded me of sitting through one of those 16mm films in high school.
Agreed. It's a shame the video was too low resolution to really see the details like surface finish and spindle markings. This content is excellent and a clearer image would make it absolutely invaluable.
Thanks a lot the video helped my children to understand my explanation fast.
Beautiful lathe
What would be the swing on that bed you are using ?
Thanks I'm enjoying your vids !!
excellent knowledge and video thanks
Dude! Thanks for the video. I'm a septuagenarian just beginning and appreciate your professionalism.
Great video, I was just given a 9" south bend lathe and can't wait to get started to learn the capabilities of the lathe. I have no idea as to what all the parts are for.
Lucky you.
Wow, Dexter really made a career change at some point in his life.
Thank you, just wish I seen this video before I bought a lathe.
Hey sir. Nice video...salute. 对床机学生们您的视频很值得一切谢谢
Looks ! Quite ! Ready ! To be Given ! To ! Charity ! Now !
Very informative video. I am just curious to know what made and model lathe is used here?
Great stuff
Cleanest lathe I've ever seen
Very good beginner tutorial.
Any chance of reshooting it at 1080p with a little better lighting on the close-ups?
This is Awesome!
very well done!
Thank you
Thank you for video.
Is somebody who's getting into using a metal lathe this is a very good informative video. The only downside I could say is I wish the lighting was better especially when he was doing the close-ups of the different types of cutting tools. But still a lot of really good information.
Felt the same, yet once start seeing the cutting can understand how the angle and the bits go.
superb...very useful bit...thanks a lot sir...
Very nice video. Thanks
Really excellent Lathes 101. Are your "lectures" available as a DVD set? I for one would buy them.
When I am parting off I lock the saddle to the ways when everything is ready to start cutting. I found it helps get much better results.
Available on Betamax.
here's a tip that I found very handy and I just discovered it by accident when I'm drilling something or mailing or anything like that shaving I have a huge big magnet and lay it under the work pace it accumulates a lot of the shavings not aluminum shavings but the metal ones and helps with clean up tremendously. they're the ones I use for welding to line things up on a 45 degree angle I got them at Tractor Supply they weren't very expensive 3 to a kit
Very good. I like it
thank you so much
I’m a well driller, not a machinist. However, we have a lathe in our shop and I’d like to use is safely and properly. I noticed there are different speeds on ours. How do I decide what speed to use on the part or is it just a rule of whatever I feel comfortable with?
nice and great sharing of knowledge , please make more educational videos sir.
