- What to do with your lathe in the first few hours of operation!! Understand the essential functionality, Head Stock, Spindle Speeds, Gearbox Settings, Lead Screw, Feed Rod and Half Nuts. Practice Feeding, Basic Threading and what to make for that first project!
This video demos all the features of a Precision Matthews 1440TL Lathe. Gives you some practical examples of what to practice to get comfortable running your lathe and goes through cutting a thread and making one project to practice freehand contouring on a lathe and provides plans for another lathe project.
Lathe Operation - 0 to 14:25
Practice Feeding, making first chips - 14:25 to 28:15
Basic Threading Operation - 28:15 to 37:35
Freehand Contouring - 37:35 to 53:00 (making a chess pawn freehand)
Project Idea - 53:45-54:10 (screw jacks, other plans for similar in this thread)
If you watch my video on Lathe Quick Change Tool Post Speed Nut, that will provide more details for making a part similar to the screw jack plans provided in this video. Link to Speed Nut Video - • Lathe Quick Change Too...
Thanks for watching!

Have you been a teacher/trainer before? This is very well done. Slow, methodical, and clear instructions.
Thank you for the feedback, really appreciate it. I did some training when I was in the military yes, and worked in a training role in corporate for several years, mostly for computer based training and just years of leading meeting etc. Happy to be able to use all that experience in my shop.
Never seen any more comprehensive introduction to a lathe and general basics. Precision Mathews should hire you as educator ! Impressive !
Peter C - Thanks so much for the comment and the feedback. Glad you found this helpful. I think right now PM sells everything faster than they can get it. Maybe they will need marketing support one day and will pick me up. 😁
This is an awesome video. Working on fundimentals at the controls without worrying about hitting tolerances is a great way to start. Thanks for keeping it real for us newbies.
Ed, thanks for the comment. Glad you enjoyed the video. All the best with your learning, it is a lifelong journey I assure you.
Great video. Normally we see the tool making chips. But here the emphasis is on the hands and controlling the lathe. Excellent.
Terrence Redding - Thanks for the comment, glad you found it helpful.
Enjoyed watching this one. I have a new 1440 size lathe coming, and I really wanted to see THIS. The hands on physical operation. No one else really spends a bunch of time showing how the bigger lathes are run. You did a huge service to everyone by using this camera angle. You could have had more views on youtube by showing action shots like everyone else of the piece being turned but you actually forced the focus of the video to be the instruction in physical operation with your hands and the sounds you hear and NOT what you see happening to the part. So thank you for spending an hour focusing on this. It will make the first few runs on my new machine much less intimidating.
advil000 - I appreciate the feedback. Great to know this was helpful for you. Congrats on the new machine, such an amazing journey ahead for you as you learn. I do love views but the goal of my channel is to help people. I hope some of my other project videos help as well. I try to share the whole process, my thought process etc. to really help you get a feel of tackling it yourself. All the best!
Great work. As a fellow TH-cam machinist TH-camr I am impressed. Concise, well spoken, good lighting, clean machine. Takes lots of work to pull these off. Keep going new sub!
@VanoverCustoms - Thanks for the comment and the feedback. I keep trying to make it a little better each time. Looks like some good content in your channel, I will check that at more as well. Thanks for the sub!
Thank you Bud! We appreciate the shout out. Let us know if you have any questions while using the app.
Machinist Calculator - My pleasure, happy to share what works for me in the shop. I love this app, I use it pretty much every time I am in the shop and often when I am not, I use the drill chart all the time for my decimal chart, ordering tap drills etc. Your website cncdirt.com offers great resources - Thank you!
This was a great video. As a guy who worked as an inspector in an aerospace machine shop, I always loved to watch and learn from the operators and tool and die makers. This video is outstanding for a new lathe owner with a basic understanding of turning who, more than anything, wants confirmation that they understand the anatomy of a lathe, what the controls do, and whether they are practicing good/bad habits. I'm looking forward to watching more, and subscribing right... now.
Matthew Peterson - Thank you for the comment and the feedback. And thank you for subscribing. I hope you enjoy the channel.
Fantastic tutorial. Old guy here and am starting out on a LeBlond Regal 13x30 standard shift. Your PM lathes is one good looking machine.
Scruffy - Thanks for the comment and glad the information was helpful. I have never run a LeBlond, just looked up the 13x30, and that is a nice looking machine as well. Old iron tends to be good iron. All the best!
Thanks for this introduction. I guess most of us watching are just about to invest in our first (and much smaller) lathe. You de-mystifying the functions of a professional tool helps me figuring out which features I need/budget :)
Mikkel Bom Simonsen - Thanks for the comment. I am glad it was helpful. To your point, the basic functions of manual machining are the same regardless of the lathe size. All the best as you select the one that best fits your needs.
I know nothing about metal machines. I do know enough to know that is a wicked nice lathe. I am a woodworker that LOVES tools. That is a nice tool! Your video was super well done. I really enjoyed watching you work your machine. If I ever need something made you are my go to guy! Well done.
@Timber2Toothpicks - Thank you so much for the feedback and very kind words. Glad you enjoyed the video and I look forward to when you need a project done. 😁
That lathe is beautiful. Crazy number of features and it's so clean I thought you had just gotten it. Thanks for being so thorough for those of us with more interest than experience.
I'd love to come across an old lathe as a starter, but even imported mini lathes are so expensive.
courier11sec - Thanks for the comment, it is an awesome lathe to run. It was fairly new in this video, maybe 5-6 months old. I still try to keep it pretty clean though. My shop is to small to let clutter build up. With supply chain issues prices seem to be going up on everything. Good luck with your search. I hope you find a good deal out there. Great hobby to get plugged into.
Good info. I watched this vid simply to eyeball your lathe. Love Precision Matthews machines. I live 5 min from their wear house and am waiting one one of their mills to come in now. Keep um Coming Bladz. Thanks
Josh White - Congrats on your new mill and thanks for the comment. Yes, PM machines have a strong reputation for a reason, they perform well. Thanks for watching.
Great video Bud. I do not have the same lathe and hence features but I just went out to mine to check a few things you pointed out. Looking forward to other videos on your channel.
Warren Parkes - Thank you for the comment. Glad it was helpful.
Nice job.
@@Wild_Continental Thanks! Appreciate the feedback and the comment.

And already you have fixed VFD . Great 👍 thanks for your previous replies 👍🥂
Gurudan Singh - Yes, this lathe has some nice features and the VFD was a great addition instead of just using a Rotary Phase Converter. Welcome!
Fantastic job, lots of practical and important safety info, and a very organized and beautiful lathe setup. Thanks!
Anthony Allison - Thank you for the comment, glad you enjoyed the video. I really enjoy running this lathe.
What a great video, man. Energetic, vital, put to the point. Added to my playlist! And yes, that advanced “Chinese lathe” is a joy to watch)
fenchelteefee - Thanks for the comment. Glad you enjoyed it.
I found your channel yesterday. Very nice.
The bit on free hand turning was most useful .
I would like to see detail shots of working the dials
Excellent channel.
Tony, appreciate the feedback. I will plan to put more on that in a future video. Thanks for the idea.
I have found this to be an excellent video! I have learned a great deal and I am a new subscriber, thanks!
@russelljohnson6243 - Thanks for the feedback, glad to here this was helpful, and thanks for the sub. The video coming out later today has a lot of manual machining as well. Long video but a lot of different operations in it, facing, turning, drilling, tapping and parting. I hope you enjoy it as well.
Thanx for your time !
The Bot formality known as Dale Sather - My pleasure Dale. Appreciate you watching the channel.
Great video like no one elses...I like the view of your hands working the controls. Quinn is my go-to lady for lathe and milling machines tutorials, and one of the reasons I bought a PM lathe and mill (PM-1228 & PM-30). They're (PM) setting up the DRO's and will ship later this week. Getting excited. I might do a Rook as my first project... I'm getting a BS-0 from them too... Love your channel, and keep up the great work!
Christopher Enoch - Congrats on your new machines and welcome to the channel. You should be getting excited some great days ahead for sure. All the best getting your machines set up and getting started. My recommendation as in this video is make some chips get comfortable running your equipment before trying an actual project. The low stress tends to help focus on just the learning in my opinion. After a few hours just running a machine. Then try something.
Great Video! Thank you for posting! I've already watched it a couple of times!! It would be great to see a video of the tooling you use and recommend! My PM-1236 arrives on Wednesday! Can't wait!
Thanks Pete, glad that was what you were looking for. And thanks for another great idea for a video. I will be happy to share what tooling I have and would recommend. I will work to have that one next Saturday morning. I have another video and will likely put that out mid week. Customer project, repair job and no mill or lathe used so another lathe video sounds better. Have a great week - how could you not Wednesday will be awesome!!
Pete, I recorded the tooling video yesterday and will get it edited this week and posted Saturday morning as planned. Hope your install goes well on Wednesday!
Pete I hope your new Lathe arrived as planned. I finished the Lathe Tooling from Headstock to Tailstock video and it will be live at 7am. I hope you like it and it helps you get your tooling all set up for your new machine.
Thanks for sharing. That’s a beautiful machine and your explanation of its features was excellent.
Thank you, glad you enjoyed it!
Great video man! The more I see of that lathe, the more I want mine to come in on the boat. Thanks for sharing!
Bob glad you liked it. I know what you mean, I remember waiting for mine. Takes what seems like forever, so with it when it arrives though.
Amazing
@powerhous6706 - Thanks! Glad you enjoyed it. Appreciate the comment.
Very good , thanks for your help.
@SuzanBouchard - Thanks for the comment, glad it was helpful.
This lathe is a real Rolls-Royce, it didn't cost a bridge, it cost the price of a viaduct! I just have my eyes left to cry ...
Ce tour est une vraie Rolls-royce, il n'a pas coûté un pont mais bien le prix d'un viaduc. Il ne me reste plus que mes yeux pour pleurer...
Roland- thanks, it is a beautiful machine to operate.
@@BladesIIB Oh, yes i can believe you, my lathe cost 1790 euros, but it's a little 600 mm between center (full manual basic model)
@@rolandchardon676 that sounds great. Sharp tools and your skill behind the hand wheels and I bet you make some beautiful parts.
Great Video, Thanks
Anonymous User - Appreciate the comment. Glad you enjoyed it.
A cool first project i did on a lathe was a peg in hole sorta thing with the outside diameter being the same on both peices to the point you couldn't see it was 2 peices. i ended up having to drill a hole in the bottom to put the peg in the hole as it was so tight and i couldn't force it in due to how air tight it was. I was pretty proud of it to be honest, took me 5 hours for memory.
Bloke Beershed - Sounds like a great project and worth being proud of. Thanks for the comment.
@@BladesIIB cheers mate🤙
Man i appreciate your videos. Thanks this was really great for a beginner like me.
Dev Everything - Thanks for the feedback. Great to know the video was helpful. All the best as you learn your machines. Truly the learning never ends.
I like these types of machine.
@powerhous6706 - Yes, this has been a great lathe. Hard to come up with anything not to like about it. Thanks for the comment.
Thanks for sharing... Really nice explanation.
Thank you! Really appreciate that feedback.
Good presentation. I see you have a real lathe, not a "toy" one as I call them. I might buy a lathe just to have some fun with but it would be a mistake for me to spend money on one that I was unable to use to it's potential. I would probably buy a "toy" (hobby) one. But no matter. I in my middle eighties now and have no ego to bruise. I can handle it.
@JamesSimmons-gv4ow - Thanks for the comment. Glad the video was helpful. Let me just say that some amazing parts can be made on those "toy" lathes you speak of. Also, how they work is very similar for any size lathe. Some small ones don't have power cross feed etc. but the basic workings is the same for any size. Ge the one that suits what you need and enjoy the heck out of it. Middle eighties sounds like a great time to start something new, I hope I am doing the same when I get there. My grandmother enjoyed 104.5 years, and I just hope I got some of those good jeans. Cheers!
@@BladesIIB I am sure a skilled, experienced person can turn out some good stuff on one of those little lathes.
Looks like a 1440TL series? Very nice bro. I want one PM lathe and a Mill. Maybe a Mikron WF2. Once I can save some $$.
@rsz90182 - Thanks for the comment. Yes it is a PM 1440TL. Has been a great lathe for me. All the best getting your dream shop together.
I love this lathe
Asraf Ali - Thanks, it is a great machine to operate.
By far the best video I could find on how to work a lathe. Quick question, I noticed it looks like your range lever on your headstock was set to low range but you were cutting at 1,200rpm. Was that an accident?
@Edward55221 - Appreciate the feedback. Glad you found it helpful. The Low High lever you are looking at on the headstock is not for RPM (those are the top two levers) but controls the power to the gear box and the speed of your feed rod and lead screw. When you put that lever in High it is for very course threads or very fast feeds and gets those rods moving so fast that you actually can’t run the RPM above 360 safely (assume rods could whip and bend). So for any spindle RPM above 360 you need to have that gear box in Low. I hope that makes sense. Feel free to reach out with other questions.
I see now. Thanks for the clarification@@BladesIIB
Love it thank you
Dan Peterson - Appreciate the comment. Glad it was helpful.
Very nice video with a lot of good information. Just too bad I will not be able to afford such a nice lathe like that 😉
MrTrollgubben - No worries 😁. Most manual lathes have very similar controls so the knowledge will transfer to what you have. I do feel very blessed to have this lathe though. Thanks for the comment.
Thanks
Asraf Ali - Welcome, appreciate the comment.
Thanks for your sharing.
The beautiful machine..
i hope can have it s..🤲🤲
So cool lathe. I wish I had the space...or better, my garage won't support that weight. I have a 250 kg lathe. Regards from Florence
Thanks Roby, glad you have a lathe. A lot can be made with a small one. I figure this weighs less than a car so figured my garage would not complain. I went to Florence once for work, beautiful city.
Nice vid. I've been itching to pull the trigger on my own lathe. I assume yours is in the garage. That's where I'll be keeping mine. Do you keep the work space conditioned ? When does cold temps affect machine set up?
David Bartl - Thanks for the question. Yes my shop is one bay of my garage. It is walled off and heated and cooled for year round use. I am not sure where you might run into issues with a cold machine. I am sure the owners manual would give you a safe operating range. I used to do portable machining outside when it was well below freezing so may come down to what you can operate in. 😁 Cheers and Happy New Year!
I just want to add something...
If you want to use the tailstock as a means to center your tool bit, do this with the assumption that the lathe is properly leveled. If it is not level, then the tailstock is not accurate. You should level your lathe no matter what anyways.
Tyler Fu - Yes, hopefully everyone has put some effort into leveling their lathe. I think it would have to be off a fair bit to change tool height to bad though. The tail stock and carriage will still be down on the ways, so should get most tools close enough to cut well. The issue for me is being able to set tool height when the tail stick is in use holding your part. I built a tool height gauge for that purpose. Thanks for the comment.
Reminds me of that song... the shin bone is connected to the leg bone, ...
Tyler Fu - I remember that song. Thanks for the comment.
@@BladesIIB Yea I only heard that song watching Rain Man.
By the way I got a Victor lathe. Not brand spanking new like this precision matthew thing but it does the job. I'm in Taiwan and in Taiwan Victor lathes use A1-6 spindle nose, not camlock, so it makes chuck changes a bit interesting. I had requested the dealer put a 4 jaw on it because the problem with 3 jaw chuck is they almost NEVER EVER come with the reverse jaws, and getting replacement jaws for those is nearly impossible. But I really like to get a 3 jaw like the one you have on your lathe, just so I don't need to move heaven and earth to find the reverse jaw if necessary. However I wonder if a 4 jaw is enough, it does make grabbing square stocks easy but having to indicate them in every single time I put stock into it is tiring.
The only problem with the victor lathe is that to cut metric threads (which is common in Taiwan) you must change the gears. And of course the lathe didn't come with any gears. However my lathe uses timing belts instead of gears and I was able to get replacements cheaply off of Taobao. A Victor dealer in Taiwan wanted to charge me nearly 500 dollars for the change gears (I mean timing pulley) otherwise.
@@taiwanluthiers Sounds like a nice lathe for sure. Many lathes I looked at required the change gears as well so very familiar with what you are talking about. That is one of the things I liked about this model was having that built in. Regarding the chuck, if you will only have 1 the 4 jaw would be my choice. Yes dialing takes that extra couple minutes but you have a lot more versatility. I do a lot of small work and really like the collet chuck for that. I hope you are able to find a good 3 jaw with the jaws you want. Tooling is something that tends to continue to build up over time. Good luck.
@@BladesIIB My only trouble is, all the collect chucks out there are only for camlock spindles. I have not seen one made for A1-6 or other spindles (like those L threaded spindles). I looked all over Taobao/Aliexpress and can't find one. It looks like I am going to have to try and make my own.
Oh and by the way, the 4 jaw chuck that came with my lathe has a broken thrust bearing. I had to machine another one out of a scrap piece of medium carbon steel I have lying around. Just torch hardened it by surrounding it with fire bricks and blasting it with a torch.
I cannot find pre hardened 4140 in Taiwan though, they only have annealed ones. Annealed 4140 machines like shit, will not give a good finish no matter what (it machines like mild steel basically). Once you harden it, it machines beautifully. I had to use the torch in a firebrick trick to heat treat it.
@@taiwanluthiers Sounds like some interesting projects for sure. I agree that annealed 4140 is not near as nice to machine and heat treated. Try searching for heat treated 4340 another nice steel. I have seen some home made collet chucks and they are really nice, I think that could be a great project.
Would've helped if we could've seen the workpiece, while it was being turned, in the portion prior to the threading.
BedsitBob - Thanks for the comment and the feedback. I have done some other videos with two cameras to provide that view, I will try to do that more often to give that added perspective.
Ever since I saw Joe Pi cut threads from the chuck out, I do the same thing when there is a pucker factor.
I know you are a heck of a machinist, just wondering if you prefer not to use the method??
Love to see you on HM!
Jeff, great question and thanks for the compliment. I just took a look at Joe’s method. Nothing against it for sure, guess it comes down to what you are comfortable with. In the case of my small diameter, (if not this video another) my stop window before crashing into my live center is about the same or narrower than stopping in my undercut so not sure I would have had an advantage? Like so many things in the shop lots of different ways to do it. Knowing more ways is good because sometimes one way really does help in a situation. Also, thanks for not giving Joe’s recommended thumbs down for long sleeves. I have always worn coveralls and in my mind flinching from a hot chip can be as dangerous. Bottom line, be safe no matter what you wear in the shop. Totally agree jewelry has no place and I do try to remove mine always. 😁
@@BladesIIB
Ha Ha,
Joe Pi is a very intense professional for sure. Watching what he is doing with that small lathe model is amazing on a full size mill and lathe.
He is a magician for sure.
The old school machinists in pics have shop coats=long sleeves. Awareness rules the day. You know what you're doing!!
@@jeffanderson1653 thanks. I have seen a few of his videos pop in my feed. I have not seen the mini lathe ones, will have to check those out.
I haven't had the time yet, you and I spoke about directly to talk together on our phones. Tell me more about your particular Lathe. Who is manufacturer, your throw diameter and bed length. I assume the screws are not metric? Those are my questions. Also it came with the VFD or you installed one??
Kieth - the Lathe is a Precision Matthews PM 1440TL. Throw 14, length 40. They also make a 16x40 and a 16x60 in the same lathe. I purchased the VFD from Precision Matthews but I had to do all the wiring and installation. If you check my channel I have a full video just on the VFD install and wiring. Feel free to send your contact info through Contact Us on www.BladesIIB.com. Thanks.
Lathe speaks: "Nice beard you have there. It would be unfortunate if something happens to your neck."
@kimmoj2570 - Thanks for the comment. It is much more trimmed back now. 😅
I'm new to machining . I'm confused about the high position do not exceed 380 rpm , That's written over your forward and reverse levels ? I've never seen any warning on my lathe like that .
Kevin Edwards - Fair question, I looked in the manual and could not find anything on it so I am sure PM could give a more accurate technical answer if you asked them. I never asked because my thought was in those high feed rates at higher RPM the carriage would move fast enough to increase the odds of a crash and/or the feed screw and lead screw would be turning fast enough they could whip and bend? Not sure if that is the correct answer but seems logical enough. Sorry I don't have a better answer for you on this one.
What brand lathe are you using?
Dr. Paul Alpha Grant - The Lathe is a Precision Matthews 1440TL. Thanks for the question.
Beautiful lathe. Is it a Precision Matthews 1440 ?
Impressive presentation .
Yes, thank you. The Lathe is the Precision Matthews PM-1440TL. Glad you liked the video.
I believe the T means Taiwan = better quality
Nice lathe ! Sweet asian copy of our Colchester student 1800, almost identical. What make model please ?
This is a Precision Matthews 1440TL or PM 1440TL. I know the label on the machine is TL-1440 but there website refers to it the other way around. Has been a great machine so far.
Sun Master Taiwan lathes
Not to be rude but the surface finish is not very good. Is that the lathe's fault? Too much runout? Is it not steady? Or is the tooling worn? Or you weren't making a finishing pass?
Ryan R - Thanks for the questions. The lathe is fine, to long ago for me to recall exactly the issue but I would think just worn tooling. When just working on practice parts I usually will not put a fresh insert in.
Сool, then I'll also try to sharpen a pawn out of chess on my own, I'll also let the first shavings go.
wow what a nice lathe, what kind is it?
james johnson - Thanks for the question, my lathe is a Precision Matthews PM 1440TL. One of their Taiwanese models and the level up from the 1440GT. I love it and would definitely recommend it.
We can’t see the cutting action.
Barry Weissburg - Appreciate the feedback. This video was meant to focus on the fundamentals of the controls vs a focus on the part. Some people found that helpful, sorry to hear it did not hit the mark for you. I have several other videos with this lathe and more focus on the part and the cutting action. I hope you will enjoy those.
Do you EVER use this 'hospital' clean lathe!?!
@russelljohnson6243 - Ha, yes it does get used. Windex, is great for keeping the painted surfaces clean and it was very new in this video. One coming out later today and you can see how it is looking a couple of years in. Thanks for the comment.
I would really like to see you repeat that pawn 15 more times with that method and see if any of them come out the same.
I appreciate the request. I can already assure you they would not. That is why after finishing it I referred to that as free hand contour practice. If I had to make 15 the same I would grind some custom tooling to make the radii more uniform. I may even consider a ball turning jig to mount on the lathe. Or set up a model on the tail stock and use a dial to trace it to keep me on path. Artistically you could get them looking like a cool truly custom chess set. If going for Precision jigs and tooling would be required.

@@grantensrud9185 Ha, it does take a little practice working both wheels. In a mill it can be easier since you can draw a sharpie line to follow. On the lathe you just have to see the shape being made and keeping a taper smooth would be tough for sure. 😁

I have had a few others and I make some of my knife parts on the lathe and sell my knives. Eventually it will pay itself off, which is more than most hobbies so well worth it to me.
@@BladesIIB amazing. It's certainly far more lathe than I need, but it makes me wish there were smaller lathes in a Taiwanese flavour, which I'd happy pay a couple of grand premium on.
@@eddtube If I am being honest it is more more than I need on a daily basis as well. I waited 20 years to get one so went all out. Check out the Precision Matthews website.

@@BladesIIB I'd love to buy from PM, but I'm unfortunately in Australia, so smaller sized lathes are limited to basically Hafco (similar to Grizzly) and Sieg. I'm likely going with a Sieg SC10 soon. Anyway, at least you'll never regret going too small or having to worry about messing around with change gears!

well it's a lathe th-cam.com/users/postUgkxN9zrzkkhnjUF5PQbuA_B1gYdsfCu9k6z but it wasn't what i would have anticipated. Headstock, tailstock, carriage apron are manufactured from aluminum now not cast iron. The spindle diameter for the bearings is too small allowing for a few play in the spindle so I am using some blue Loctite to take out the play.
@andyjame1892 - Yes, this has been a great machine. Thanks for the comment.
I recommend short sleeves. If you catch fire because you are too hairy, shave your left arm.
Bud hello, I wanted to know you do not know what pressure on the lathe bed guides is optimal for working on it for a long time, how many kg per cm square, or pounds per inch square, if you know, tell me, I know roughly how the words are translated into Bud hello, I wanted to know you do not know what pressure on the guides of the lathe bed is optimal for working on it for a long time, how many kg per cm square, or pounds per inch square, if you know, tell me, I know roughly how the words are translated into English (a little colloquial) and translates in simple terms, you probably don't have such words.
I am familiar with Pounds per square inch (PSI) but not as it would relate to lathe bed pressure. I have never seen this used for a lathe specification and even if given for a lathe, I would not know how to accurately calculate that? Lathe beds wear over time but I think mostly from the movement and grit build up. If they are a good casting and hardened I am not sure pressure is the biggest issue. I think you will break a lot of tools and took holders, and have power and chatter issues before bed issues. Just my opinion though. Maybe someone else can chime in with a better answer for you.
@@BladesIIB аs I understand it, this means abrasive, the most important thing is not to sharpen cast iron, they told me its dust as an abrasive, and not to put the machine next to the lathe, I didn’t come up with this system, I just assumed that engineers lay it like this, in my machine passport written 0.2 mm revolution at 2 mm depth, the speed of 100 meters per minute is a rough roughness, but in the advertisement I saw 0.3 mm / revolution, the depth is 2.5 mm, the cutting speed is 50 meters per minute, while I do not know this in the advertisement the exact parameters or not, I have a Walter calculator, installed on my smartphone, I don’t know how exactly it measures, well, in general, it’s not very good, but there’s nothing better, because according to its first settings, a cutting force of 80 kg of force is obtained. So I want to conduct an experiment. I want to calculate the area of the surface adjacent to the guides and calculate the quadrature and divide these 80 kg of force into the number of squares and see what load the square of the surface of the guides takes on in order to estimate whether it is possible to increase the modes or not.
@@BladesIIB your machine is better, but it is not suitable for the imperial system and does not fit the metric, I saw there 2.55 inches, -through in the spindle, if it were not imperial, then I would not continue to search, and think, in the future I would buy , but ... I wanted to know where you can see the technical characteristics of your machine, at least a link, I could not really find anything, and the size of the screw for the thread, the one for the mother nut, I think this information even with all the links is not find, on mine 0.7874 inches, I want to compare with my own, how much my toy compared to yours.
@@user-ul9qe9sl9c good luck with your experiment, sounds complicated? I use SFPM for speeds and inches per revolution for feeds and go by feel and finish to adjust as needed. I am not sure I see the value in calculating the pressure on the bed? Maybe I am missing something.
@@user-ul9qe9sl9c here is a link to the full details on the lathe. They make a full metric version as well mine is the imperial model. It has graduations for imperial or metric and the DRO has imperial or metric so fully capable of machining in either. The main difference is mine has a true imperial pitch lead screw for cutting imperial threads using the half nuts and thread dial. For metric threading I have to leave the half nuts engaged and not use the thread dial. On the metric machine that would be opposite thread dial available for metric threading and would have to leave half nuts engaged for standard threads. The diameter of my lead screw is 1.125”. www.precisionmatthews.com/shop/pm-tlseries-ultra-precision-lathes/
You only need that chuck key to bounce between your legs once to realise you MUST NEVER do that again.
@DodgyBrothersEngineering - sounds like maybe some personal learning there. If you survive the mistake the fist time, I agree, it is a pretty good lesson to never do again.
@@BladesIIB happened to me in the mid 80's, while I was at college. Was a decent sized machine too. To this day the thought of a T handle being left in a chuck sends shivers down my spine.
@@DodgyBrothersEngineering No doubt. Close call for sure.
I'm guessing this is your first lathe.
This is the first one I have owned yes. I have operated several others.
!!!!!!!!!!!!👏👏👏👏👏🤔🤔🤔!!!!!
@user-ne3du5np2h - Thanks, I think. 😁
Do you realize we can't see a thing?
@johnseal6103 - I appreciate the feedback. This video was not meant to show the part, just how to operate the controls on the machine. Many have found this perspective helpful. I do have many other videos on my channel of the lathe in operation making parts with the focus on the material being cut if that is more what you are looking for.
