Thank You for Watching :D
Great work my friend! As advise from a welder, always try to weld the parts before the final turning, to avoid deformations. Cheers!
I am glad you changed out the shaft to hollow tube makes it so much better.
What you are doing is impressive. Just a comment for your safety. Ive been a machinist for over 50 years. Put some glasses on and lose the sleeves on your shirt . I had a friend have his shirt ripped right off of him because it caught a burr on the od of a shaft. Another guy lost an eye because of a broken center drill. Just my opinion. But nice work
Awesome upgrade. I'm thinking of doing the same from the beginning of making my lathe 😁 like the tight fits everywhere
WOW!!!!!!!!!!!!!!!!!!! THAT'S AWESOME WORK!!!!! THANKS FOR "SHARING" THIS VIDEO!!!!
That is absolutely awesome my friend!! That looks like it could turn way above its belt...
Very clever, also looks good for a homemade lathe.
I applaud your spirit, but please machine *after* welding !!
I think it's better not. Because in this situation, any rigidity is important. Also, there is a high risk to deform (band) all construction.
While it worked, better to rough it in, weld then do finish passes. I think that’s why the bearing journals didn’t press on easily.

I've only just seen your channel for the first time. I am greatly impressed by your workmanship and ingenuity. I am now subscribed,keep up the great work👌
Thanks :D
@@dexter1448 A couple of people have mentioned you may have problems with bearing lubrication. If it does prove to be a problem then a couple of drip feed oilers with adjustable needle valve control would be a simple solution/fix.
Superb work. I was a self employed welder / turner and then went on to teach. I really enjoyed your video. Always room for improvement and you are clearly moving forward with your work and skills. Fantastic - keep it up.
I am a chemical engineer however my first love is welding and fabrication.I am starting a mobile welding business as well as fabrication and small engine repair. The small engine repair is mostly for construction and landscaping equipment. I specialize in obsolete machines and equipment. I am building a machine shop full of 1800's machines asns a central belt powered from compressed air and steam. I will hide the cnc in another building..lol
Awesome build. You could add locating pins to the spindle mounts to lock the spindle location and maintain trueness during machining. Those 4 bolts on each side will move with pressures of machining.
I just watched the entire lathe series and you are a genius!
Thanks :D
Kid im impressed with your skills. Im a knife maker for 35 years and I think you’re lathe build is awesome 😎
Thanks :)
Great job, congratulations! I would just recommend using high-quality grease on the tapered bearings.
Love your channel. I am a machinist by trade and your videos are inspiring to watch! To see someone create such an impressive machine with rudimentary tools is awesome! Keep up the good work! (And invest in some eyewear, removing chips from your eye is painfully, ask me how I know.) I would also recommend you drill some locating pins to the bearing flanges so they don't shift if there are any excessive loads, or if you have to take them apart.
Roll pins would work great.
I'm really glad to see at least one young man actually doing man things getting his hands dirty and actually making things I applaud your enginuity young man. Also I have a 2.5hp motor that would make that lathe a monster I'm going to put it on my lathe and hopefully make mine a monster lol
Thank you very mutch :)
@@dexter1448 your very welcome you do good work keep it up.
Wow! Those are great results. Thank you for sharing.
Thank you too :)
you are amazing and talented. Your workmanship is beyond impressive. I would suggest you build a much stronger, stiller table for your lathe, full of drawers for all the accessories, to add mass and stiffness. Your current one seems to wobble as you tighten and tap on it. Another fun project ?
Very very impressive what you do with just basic tool to begin with!!!! We all look for that heavy, stable, huge lathe while you’re painting circles around many with a homemade lathe on a shaking frame!!!!!! You’re awesome, dude!!! One thing you did that I gotta comment is the fact that you made the flange to match the Chuck size perfectly but, in reality, every commercial lathe has a little play between the Chuck recess and the flange center with adjusting side screws so you can fine tune those differences you were fighting with the frame screws to be running true. If you leave a couple hundredths of a millimeter you can fine tune the Chuck to almost zero runout. Don’t take me wrong, you did it much better than I could, it’s just a matter of making it easier on you and increasing precision to your final product since you could get it very very close on the large frame bolts then really fine tune it with the flange screws. Watch a couple videos on installing a new Chuck it may be better than my explanation! Awesome! Awesome! Please, keep up your great work and don’t get mad at your dad! Wish mine were picking on me and joking about my endeavors but he never did so, consider yourself blessed that yours want to be part of your life!!!!
Thanks for your Comment and your idea! 😊👍 My dad and I get along just fine, we just tease each other for fun 😉
Awesome build Sir, inspiring, thank you for sharing :)
Thanks :)
Te felicito Dexter tú tecnología es excelente un fuerte y afectuoso abrazo.
ich hab bei meiner Drehbank auch auf Kegelrollen lager umgebaut das sind echt Welten unterschied zu bei mir sogar nur messing Buchsen . Und mal wieder Top video :D
Excellent work man!
Thanks man! :)
Hey man awesome job! I’m planning on starting my lathe project sometime next week! I would really like to see that steady rest video in the near future because it would help me a lot. Thanks for the amazing content and keep up the good work!
I agree .. I'm making small setup but I need as much data as I can assinilate... good luck on your project
Excellent!
Nice work! Is it just me or the junkyards in Germany full of good stuff? :D
Cool video shot, thank you for sharing it, keep it up :)
You have a clever dad , after that, you are a high level engineer, nice to meet you sir...🌱🥸
Truing the round balances the stock and prevents chatter and wobble which can loosen it from the chuck.
Excellent work...Suggestion.. you definitely need to in vest in eye protection. Again excellent work. New Subscriber!!!
cool work dude
Great... You are passion mechanis
Shop presses are nice and not expensive 🙏
High pucker factor, turning the outer surface 2nd time around. Good thing CNCs can do it without blinking.
Verdaderamente magnífico!!!
Great results! Next step - make fast tool post. ;-) And by the way! You can get much more precise, if you will put your lathe on STABLE metal table. Do not use wood for it. Your machine it need REALLY syable base. You have band saw, weld machine and STRAIGHT HANDS(In Russia we told that, about peoples which do some job right ans good), so all what you need is go to scrapyard and found some metal parts. I am know it's not a cheap in Germany, but i guess you can to find something! Good luck! With this talents which you have - you will always can earn money! I am glad to see young man, which made things like this!
Thank you for your praise :) I actually have a metal base! (watch part 2) there you can see how I build them... By the way, I have already earned money with the machine, the machine has already paid for itself about 4 times ;)
@@dexter1448 Thank you gor your reply. Now i see, it have wheels, for moving. Well... It's not a perfect solution, because all vibrations came from motor, to part. If you have stable and heavy base for machine, the most of vibrations are going to this base, and you can to increase spindle speed. Also it's give you nice and smooth "mirror like" surface. If it's start to make a money - it should be best is possible. By the way! If you can to add lubrication and cooling of your bearings, it will increase characteristics of your lathe. WBR Viktor
@@viktorfreeman3607 Acho que ideal para fixar a base aos pés, seriam com fixação sobre amortecedores de borracha entre o chão e as rodas, ou até mesmo diretamente ao chão as borrachas amortecem as vibrações das altas rotações e evitariam trepidações na usinagem.
very nice job
awesome to see this ingenuity. just wondering how you lubricated the headstock bearings and aligned so precisely. Peter
Put another grub screw behind the four on your pully to lock them in so they won't shake loose.
Bravissimo, grazie.
Is there a way to grease the new bearings. ? Well done my friend..Greets from Bavaria.
Great video's You are making - thanks for sharing! Did You lubricate those Taper Roller bearings? How do You plan to keep them lubricated? When they have no seals or shields they cannot retain lubricant....
Really inspiring..a master of: do what you can, in the Place you are, with the staff you have. I apreciate so much. Only One thing: SBR rails for lathe also NO!
why not? the load is not very heavy for these bearings which can hold 1500 kg of weight without getting a permanent deformation. SBR is not very different from HIWIN blocks , just different shape and lots of machines use HIWIN blocks for displacement. You better explain your point if you are going to make any comments
Я токарь с 25летнем стажем и твоей самоделки аплодирую стоя . незабуть отрегулировать натяг плшибников и сделать масло подачу на подшипники.
Bello torno, solo te falta el automático para el carro principal con marcha atrás y adelante!!!
Impressive!
what precision grade did you use for these bearings?
Excellent
Прекрасная работа, Браво!
Thanks 😊
Everyone seems to suggest you drill some locating pins but no one suggested you do something to lubricate those bearings. They move great now but with use and without lubrication they will wear out fast.
buen trabajo !!
Was there no provision for grease seals to keep foreign materials from getting into the roller bearings? How do you grease the bearings? The bearings will soon run rough and accurate turning will be off the chart.
Excelente vai me ajudar na fabricação do meu Mine torno.
Great job but I would add some way of lubricating your headstock bearings.
Belo Trabalho de torneamento e acerto alinhamento da placa seria possivel informar sobre o modulo programavel de velocidade de avanço ferramenta
How do you lubricate the spindle bearings? Cant run them dry and hope they last.
Vary good job thank you
Thank you too :)
The issue I see is the low rigidity of the set up. When your trying to center drill the disks the misalignment of the drills and the center of the work pulls the tail stock
First time watching your video and I am really impress , Good luck my friend. subscribe 👍🌺
Should get some seels for those bearings.
Show em my friend Brasil 🇧🇷
Brilliant job!👍
Thanks :)
Ești tare
Отличный станок получился! И небольших размеров, и много может! Чистота реза поражает! Удачи мастеру!
Thanks 🙂
@@dexter1448 it has probably already been written that the rail guides used have low rigidity. The next upgrade will be a conversion to a more suitable HIWIN RGR machine. Right? 😉
@@RicoJovanni I have no Problems with my rails
@@RicoJovanni they are better, right. But the price is like 3x higher
@@dexter1448 I know the cost is higher but maybe in the future? 😉
Grandios !!!
Why did they abandon the roller bearings that were installed initially and switched to tapered thrust bearings?
Hat off tou you Sir
Respekt was du dir da gebaut hast. Ein paar Sachen hätte ich aber anzumerken: - Zwischen Mutter/Schraube und Federring kommt keine Unterlegscheibe, sonst macht der Federring ja keinen Sinn, denn der soll ja die Mutter/Schraube nicht nur durch die Vorspannung sondern auch durch die Kanten am Lösen hindern. - Willst du die Kegelrollenlager nicht wenigstens vor dem Einbau fetten, wenn du schon keine Abschmiermöglichkeit verbaut hast? - Den Antrieb für den Vorschub...da muss man auch erst mal drauf kommen. Ich würde den aber irgendwie mit der Spindel mechanisch über Zahnräder oder so antreiben. Der Riemen dürfte bei der Länge bestimmt leicht nachgeben und dann durchrutschen. Oder zumindest den Riemen auf der gegenüberliegenden Seite mit einer weiteren Rolle "abstützen"
this is very nice
Thanks :)
for the future, maybe a gearbox, there's CHEAP cg250 gearsets on the jungle site, 5 speed, can toss the starter gear, though the clutch would be useful. 50-200$, i think the quality is hardly worth the crazy price range but it does save some time over building the whole thing, can focus on change gears for power feed.
CALIDAD DE TRABAJO SALUDOS
bravo à tous 👉🔥
תבניה פראס הידראולי מג'ק של משאית...ככה תוכל ללחוץ את המיסב בקלות...👍👍👍💖💖🌺🌺🇮🇱🇮🇱
and bearings lubrification ?
Bravo pour ce travail, tu m'as inspiré surtout au niveau des vis qui traversent le cône de serrage de la poulie. Si j'ai bien compris le truc, tu agis sur elles pour appuyer contre le roulement conique et ainsi gérer le jeu longitudinal de la broche. Peux tu me dire si j'ai bien compris, merci par avance.
👍 yes you are right
Gostei muito de seu torninho
Thanks :)
Krasser Typ 👍👍👍
Selber 😜
Did you grease the bearings?
Is good 👍
good
Amazing build. But aren't you supposed to pack roller bearings with grease?? Great video.
Thanks :D I oiled them and then sealed them with rubber so that no chips came in the bearings are not particularly heavily and often loaded, so I think this should work...
On many commercial lathes such as Colchester and Harrison the tapered roller bearings are simply splash/drip fed with gearbox oil that gets lashed around by the gears. I don't think he will have any problems here so long as they get a bit of oil periodically. A drip feed system might be a good addition.
1) How're you going to oil or lube those shpidle bearings? Bearings go kaputt if run without lubrication. 2) Jor Germann Akzent iz rather lovely!)

How do you seal the bearing? Dust and dirt will damage the bearing
Poderia usar gaxetas de vedação.
You using a wrong turning insert the first insert is for aluminum! The Black one the yello one are inserts for steel!
Very impressive. Are you going to study Mechatronik or Enginering ? You will be top notch.
Thanks :) just finished my apprenticeship as an electronics engineer. Let's see what else I can do...
Habis berapa itu semua anda membuat mesin??
Well done ?
check your feed or sharpness of your tips, because so long maccaroni are no good, they should breake especially with carbide inserts. turning again after welding could check if there is no thermal deformation, because such thick metal always heat and cools in different rate - welds are pulling edges. especially if You would weld all around for stiffnes or for some rotating elements where rotating mass would be important. i dont get idea that many washers are better than two nuts, but one nut is always better with some locktite, or self-lokcing nut (theese with rubber gasket that grips on thread - vibration reduction as bonus)
good job but u forgot to grease the bearing
Good work. I liked the video. But I hate that green paint.
Thanks😊 but why do you hate the color? 🤔😄
Super Video, ich bin schon auf deine nächsten Videos gespannt. Bitte lass mich nicht so lange warten. Aus welcher Ecke von Deutschland kommst du eigentlich?
Moin, ich hab einiges an Videomaterial, aber mir fehlt oft die Zeit zum Schneiden... Das unterschätzt man total... Für das Video hab ich bestimmt 20-30h für den Schnitt gebraucht ;) Ich komme übrigens aus der Nähe von Göttingen
How are you lubricating the bearings?
Esses rolamentos poderiam ser lubrificado através de caixas em ambos lados, com graxa com retentor, gaxetas ou mesmo através de metal patente- tipo bronze sem encostar no eixo, mais gaxeta para vedar, banhado a óleo lubrificante.
Klasse Video, auch die Nahaufnahmen, haben immer so etwas Entspanntes an sich. Und woher hast du denn deine Kegelrollenlager und das Keilriemenantriebsrad ? Also kannst du da eventuell Links schicken?
Moin, das Freut mich :) die Lager sind Markenlager von SKF bekommst du z.B. Hier: www.kugellager-express.de/Start oder ganz einfach auf Ebay
Die Keilriemen / Scheiben gibts hier: www.zahnriemen24.de/startseite oder auch auf Ebay
Danke 👍🏻
К внутренним подшипникам нужно было добавить конусные, а не убирать. А где сальники, смазка будет на станке снова...
12:24 how do you can cuting an hypotenuse way, your lathe is only X and Y axes ? Sorry for my English I am French ^^ Great video ! 🎉
By turning both handwheels at the same time! Greetings from Germany
Já pensou em construir uma fresadora caseira??
Ive got a very good one for cheap...
@@dexter1448 Onde ver o detalhamento destas máquinas, suas medidas em desenhos para corte CNC ou os gcode para impressão? Já pensou em transformar este torno em um 3 em 1, multifuncional, torno e fresadora em único equipamento, principalmente se a fresadora deslocasse no longitudinal deste, na lateral esquerda ou por cima da árvore-¨fixada¨, assim abrangeria amplamente a fresar sobre toda superfície do torno em sua superfície de deslocamento do eixo transversal.
👍👍👍
Have you ever thought about using car transmission gear?
Good Idea, but to Heavy... 😉
Im in iran and the lath machine is so expensive i want to create one of them
