Homemade Lathe #10 | New Spindle

[@josemanon6295]

Great work my friend! As advise from a welder, always try to weld the parts before the final turning, to avoid deformations. Cheers!

[@garyg5829]

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

[@MegaTank10]

I am glad you changed out the shaft to hollow tube makes it so much better.

Eu gostaria de saber a diferença de usar o tubo oco para o tubo maciço? Pode me explicar?

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.

[@Biokemist-o3k]

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

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

Chapeau! This is by far the most amazing and inspirational video I have seen on KZbin. I have been an auto mechanic for 35 years and machine shop machines and lathes in particular are impressive to me because I have known and seen a talented machinist make some incredible things I asked of him when I was trying to build a bracelet engraving machine 45 years ago. I hope you realize how talented you are and keep at it. Thanks to you, I now have a new respect for the younger generation of today. There is hope after all!

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.

[@Wexdue29]

Roll pins would work great.

[@viktorfreeman3607]

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.

[@rallymax2]

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.

[@roadshowautosports]

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!!!!

[@tuguybear930]

5 speed gearbox from a very small vehicle would be ideal for this purpose. increased torque at low RPM. Plus the advantage of a reverse gear. Nice job overall.

[@goboyz8016]

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.

[@viktorfreeman3607]

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!

[@dexter1448]

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 ;)

[@viktorfreeman3607]

@@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

[@ciddeaguiarrezende5021]

@@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.

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.

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 ?

[@robby-cgn]

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"

Truing the round balances the stock and prevents chatter and wobble which can loosen it from the chuck.

[@johnrutherford1166]

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.

[@TheZzziggy]

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!)

[@dexter1448]

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... "2) Jor Germann Akzent iz rather lovely!) " Thanks :) maybe I'll speak more English in the next videos...

[@PotasioMetalWelding]

How many mm of material does it cut in one pass without vibrating? Have you tried that?

[@wahhworks]

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!

[@absolute___zero]

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

[@b.malnit8983]

Great job but I would add some way of lubricating your headstock bearings.

[@alexmay3533]

How do you seal the bearing? Dust and dirt will damage the bearing

[@ciddeaguiarrezende5021]

Poderia usar gaxetas de vedação.

[@sheqz5270]

Wie hast du gewährleistet dass du keine Fluchtungsfehler hast? Ist deine Schweißkonstruktion so winklig, dass beide Flansche gut zueinander standen?

[@danhammond8406]

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

[@simonwatson5299]

Amazing build. But aren't you supposed to pack roller bearings with grease?? Great video.

[@dexter1448]

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...

[@howardosborne8647]

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.

[@1crazypj]

How are you lubricating the bearings?

[@ciddeaguiarrezende5021]

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.

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.

[@mateuszm809]

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)
