I has been a while since you put this video up so I'm not sure that you will read this. At 0:42 I see orange sparks, that means you are going too fast for that diameter. You are going to burn up your cutting tool. That is why they make lathes so you can change the speed. I'm not sure if carbide is as susceptible to being burned up as HSS is but I don't imagine it will be good for it. Also, it looks like you could use some cutting oil. Cutting oil is a high sulfur oil that the guys in the old days found out worked the best. It can probably be found in the hardware store as it is used for cutting threads on pipes. Long ago I commented on one of your lathe videos and, along with another guy, told you about the thrust bearings for some of the slop you were getting. It looks like you solved that problem. Congratulations. Shortly after that I was able to buy my own metal lathe, which I had been wanting for most of my life. So awesome! I bought it for $100. It is a 1942 10" lathe made by logan for another company. It needed a lot of work but what can you expect for an old $100 lathe. There are some free old books on how to use engine lathes over on archive.org. The information in them is still relevant. They have some really good ideas that you probably would think of eventually but this way you can get the ideas without having to run into the problems first. They even have old army manuals on running a lathe and all sorts of good stuff over at archive.org. Here is one lathe book; ia800100.us.archive.org/11/items/OperatingAnEngineLathe/OperatingAnEngineLathe_text.pdf
I designed something almost exactly like this. Used the same mechanics for the gear selector, except I had four gears. I also designed an h-pattern shifter for mine. You are going to have issues trying to slam it into gear under load without a clutch of some sort. Without a clutch it will just chew the tapers on the pins. I stuck a TAV on mine and worked pretty well. Good luck!
I thought this was very creative and mesmerizing to watch. Thanks for taking the time to make it. I know little about machining but learned a lot. Hope the transmission worked out awesome!
First . I have to say awesome job . I love the lathe and the two speed tranny . I wanted to offer a couple of suggestions that might help you get a better finish on the parts you are turning . The pillow block bearings have to much play for a turning application and will get consistently worse over time . I you make a set of plates that would hold a set tapered roller bearings on ether end that you could preload a little bit the spindle will stay concentric and you will have less runout = Better parts ...... You could use truck spindle / axle bearings maybe in the three to four inch range . They are not that expensive . You will probably have to make a new spindle also to accommodate the changes . I bet you could make all of your new parts on your lathe yourself . Rough out the spindle and send it out to be ground at your local precision grinder . Show him what your doing and some of your videos . He will probably do it for free . Us old guy's like to see some one make something out of nothing and do a damn good job at it too . One more thing . If you can get a cheap set of center drills . Always center drill first for accuracy . Harbor freight / MSC / Amazon / EBAY They got em . You're awesome kid keep up the good work .
This brought back a memory. In 1957, my mother bought a King Midget automobile (look it up), powered by a 9 hp Wisconsin engine. It had a two speed “automatic” transmission. The engine had a long output shaft with two centrifugal clutches on it. The clutch closer to the engine had tighter springs than the outer one, making it engage at a higher speed. Forward of the engine which was mounted transversely, was an assembly which had two pulleys on a concentric shaft with a ratchet between them. The low speed clutch drove the large pulley and the high speed clutch drove the smaller pulley. When you started up, the low speed clutch would engage, turning the large pulley which turned the smaller pulley through the ratchet, thus low gear. As engine speed increased, the high speed clutch would engage, driving the smaller pulley directly, allowing the large pulley to freewheel, thus high gear. The output of the pulleys turned a F-N-R gear box, which drove the right rear wheel by a chain. As bizarre as this sounds, it actually worked. The little two-seater was a blast to drive, Street-legal (at the time), with a top speed of about 40mph. You could drive all week on one fill-up of the 3 gal. gas tank.
My parents had a King Midget when I was an infant. I don't remember it, but saw a picture of it once. I always wanted to have one, and I researched that transmission pretty intensively when I was thinking about building a copy. It was an interesting and clever design.
Carl Eric von Kleist, III, it was a clever design. The frame was square tube steel, and the body panels had no compound curves, so anyone with basic metalworking skills could build one. Mother’s was a 1957, ordered right from the ad in the back of a Popilar Mechanics magazine. It was shipped by Railway Express, strapped down on a big wooden pallet. When they went to the REA depot to pick it up, they cut the straps, poured in a couple of gallons of gas (the tank only held 3 gal.), and drove it home. 1957 was the first year to offer an electric starter and doors as standard equipment. The doors were simple flat plywood with an outside frame. It was a real “woody.” one of the things I most remember about it was the manual windshield wiper. A piece of steel rod through a brass grommet in the top edge of the windshield frame. It bent Dow on the inside to make a handles and you used whichever hand wasn’t on the steering wheel to wag it back and forth.
Gonna make one of these.. for my bridgeport mill. It needs 2 speeds. Has a DC 3hp motor. No longer has the original BP head, it did not come with it, it is just a cobbled together affair made with scrounged up parts. The DC motor easily allows speed adjustment but if I gear it for mid range, at the low end it just does not have enough oomph for tapping. It works but not as good as it should. Needs super low and mid range then with the adjustable speed DC motor, it will have the range needed and will be perfect. The low range will just be duplicating the original BP back gear but I'm not putting an entire new expensive BP head setup on it just to get that low speed. I'll find an old 3 or 4 spd trans and use the gears from that, could even use gears from a old motorcycle trans, those are even smaller. I'm sure I can make it much more compact then this version shown in this video. Yes, if I had it to do over again I would use a 3 ph motor and a VFD for those of you who are thinking that would be the way to go but I got the DC motor free off a professional model treadmill and the KB Electronics controller was cheap at 100.00
first vid of your s I've watched and this is super fucking cool! I love watching you use your homemade lathe and making cool projects with no fancy machinery. a sub from me
Already loved it when i saw the thumbnail. Idea for homemade Clutch: Take a differential gear, power one of the 3 shafts with your engine, connect another to your transmission, and build a brake for the 3rd, maybe a disc brake. Could this work? Would be cool and kinda be same style.
Wow! Genius design, bet it could take 100 hp. Our Heathkit dirt bike (yeah I said HEATHKIT) had a very similar 2 speed transmission activated with a simple choke cable. Like your lathe.
On one hand I'm impressed with the ingenuity, on the other I'm cringing at the lack of any kind of machining sense you could easily get from a few minutes watching some RUclips. With that said you do you and rock on.
That little nib means your off just a bit. You can tell by the nib if your high or lower. Looks like your a little high. I guess if your drilling out the middle it doesn’t matter. Great homemade lathe. I wish I had the talent.
Man i could watch metal being machined all day cool build always wished my kart had another gear as a kid now as an adult i just build em with car drivelines
Those welds will snap after a few gear changes, love the idea though. You should have added a chamfer to the inner piece and you would have been fine with a deep grunty weld. But laying a cold bead over the top to hold it together just wont last man.
When ya deburr with a file on the lathe hold the file over the back side of the work or down so it's vertical. The way you do it in the video is how ya end up with a file stuck in your gut. I myself prefer to kick the lathe into reverse and turn the file around. Comfortable angle to hold and it'll get thrown into the back wall instead of into me.
Interesting design for the shift mechanism. Obviously you have a fine analytical mind. Hope you don't mind constructive suggestions. The most problematic aspect of the design is the meshing of the shift pins, or carrier pins, being rather sporadic and needing some force and estimation of speed. Eventually, with such an exposed "hard materials" drive system, there will come wear and possible breakage. Two things would help minimize this right off. One is having more pins, like 12 instead of six, so the meshing has more chance to succeed with less force, and the other is to replace the chains with two belt drive pulley systems, in order to give some slack and give to the "gearbox" itself. The belts will take up more of the "mesh-wear" then. Also, if the gearbox could be enclosed, you could carry it in grease or oil, which would help greatly. Since you show such a proclivity for experimentation, maybe you could develop a planetary gear arrangement that would give you two speeds, or even three, with only a braking/stopping mechanism on one or two of the three planetary gear rotation planes needed to create the "shifting". Another idea, if you wish to keep a chain drive, is a super heavy-duty derailleur that could shift using one input drive sprocket and two, three or more output sprockets. It works well on bicycles that can go just as fast. Grease and oil are your best friends for all these transmissions, but not on a belt of course.
Please, never EVER wear a glove, when working on a lahte or similar tools. A glove is the difference between a nicked finger and a ripped of hand or arm. I know those chips burn like hell on your hand, but it is better than loosing it :(
Everything looked real good, till I watched you use a vise grips on a nut!!!...How do you plan on shifting, or changing ratios?? If you had another collar on the drive plates with a groove, that could be used with some kind of a fork.....Good Job!!!
Very impressive Lathework machining gears......I'm wondering if you could've used a Rear Sprocket from a 3 Speed 20" Bicycle and the Shifter handle that us affixed to the top tube (on boy's bike) ? Just a thought!
The *only* time you wear gloves around machine tools is when the spindle is OFF and you're cleaning up chips. Guy at my last employer got a very harsh lesson after drilling holes with gloves on. Nearly lost his left hand, and I'm not sure he has ever gotten full function back. He was lucky that there were other people around to get him untangled and carted off to the ER.
When using a file, turn the file around and run the lathe in the direction that will pull the file out of your hand and away from you if the part grabs it. This way you a lot less likely to get speared by the file. Interesting video!
Home made lathe, cool! Safety glasses in use, can't tell but doubtful... 100% agree, never, ever wear gloves! Hey, at least he used a welding helmet, har! PS, love the exposed cooling fan on the spindle motor or is that a chip slinger for the safety glasses:)
Hey! I am trying to build my own gokart, and I'm wondering how you shift gears? I understand how it physically shifts by catching the pins into the holes, but how do you move the two discs that the pins are attached to? Do you use some kind of shifting forks? And do the spindles with the gears on them get stuck on the pins sometimes? That could be dangerous, cuz if one doesn't let go and grips on the pins while you engage the other, you have two gear ratios at the same time on the same axle, which will prolly break the chain. Did you put on some kind of retention to prevent that from happening, cuz rn they move freely left and right on the shaft?
I really appreciate this vid, but why not just have a CVT? it works the same and without as much wear and tear on the actual devices. I would love to adopt a two great system into my mini buggy, but I lack a lathe and other components. I do love this break down however because the details and effort you went through to create it. Thanks again and keep the vids coming.
Frazer Nash cars had the same type of sliding dog chain drive trans . pretty effective in their day and lot easier to change gear than the trans of the day .
Did you know that 3dmotorsport sells a manual clutch kit that you might be able to use in this project? You should go and check it out, its pretty cool
I've never seen the paper idea for placing your holes. I've always just laid them out on my work piece. Its a technique i'm definitely using in the future.
very nice machine work,though it would be nice if the gear ratios were really varied like the left side is small nice,but the other one should be significantly bigger since two gears need extreme varying gear ratios for maximum efficiency in different modes but I guess it can also be done on the wheel axle gears
you could have encased your 2nd 2 speed transmission so you can have the transmission parts bathe in oil, put some rollers on those pieces that engage with a gear, and you could polish up some surfaces of the transmission
Nice, but are you going to add bearings to the sections that hold the gears? The shaft is spinning inside them without bearings, that can't last long... just my opinion, others may vary.
You might have an issue with the centre part sliding on a round shaft with only a woodruff key to stop it rotating. A square or hexagon or a spline would be better I think. Nice job though/
Often use very sharp tools ( 2 - 3 hours of constant work ) - it makes machining speed and acuracy highest. Moreover the machine material consumption is lower.
I'm confused. Two outputs, are you running two chains to the drive axle? There has to be a better way....... I know there is a better way! The concept is good, it needs refining, I really like the home made lathe! Anyone who can make one with a fair amount of accuracy is cool! I like the very dangerous unshielded fan as well! Please put a shield on it, my knuckles hurt just watching it run!
Dude, get that glove off when working at the lathe! It WILL be caught in the chuck jaws eventually, ripping your hand clean off !! Please, please don't do it!
No gloves when using lathes, mills, grinders, drill presses, or any other stationary power tools. I've seen pictures of a man get pulled into a lathe and his head crushed. It's not pretty.
Goodco limgpu Fuck off. Wearing gloves on a lathe is like running a chainsaw with shorts and sandals on. There is no reason good enough, to justify the risk.
@rather B welding ,can you please give me a list of the equipment used ? I'm making a gokart using your method ,and the list will be highly valued ! Thanks in advance ,awaiting your response
Dude, I really enjoy your builds. I need to say tho, your machine shop safely is lacking big time. Never ever gloves around the chuck!! And if your shooting theses videos alone.... love the content just be safe.
its too bad you cant get a set of brake pads on springs to act like a synchronizer (or even the clutch rings from a motorcycle clutch). also, a center drilled hole, with a ball bearing and spring makes for a great detent to hold it in place. might also use a centered spring to force it one way or another to help override the springs in the sync/ hold it in gear.
Couldnt you just put two of them in series for a 4 speed transmission or more formally a 2 speed with low and high? Or maybe even more than 2... I'm very curious now
I has been a while since you put this video up so I'm not sure that you will read this. At 0:42 I see orange sparks, that means you are going too fast for that diameter. You are going to burn up your cutting tool. That is why they make lathes so you can change the speed.

Hey! Your videos of the homemade lathe inspiring me, now I'm making my own and making videos in Spanish of it, thank you for sharing you work!
Very good design, nicely done. I love making things and making them work. Good job.

Very nice!. Simple, effective, and robust. And completely home made. I love that kind of stuff.
Nice job!

The most gorgeous lathe I have ever seen. And I've seen 1 or 3.
You are so resourceful!! I would like to see what you can do in a well equiped machine shop. Congratulation!!
first vid of your s I've watched and this is super fucking cool! I love watching you use your homemade lathe and making cool projects with no fancy machinery. a sub from me
you have skills coming from a machinist the glove thing dont do it
Plz make 2 speed with reverse gear box for go kart
Already loved it when i saw the thumbnail.

Interesting vid. I like the lathe. It obviously works. I would like to see a few detail shots of it.
It would be nicer with a angle travel tool holder.
Holy moly my friend that's amazing!!
That little nib means your off just a bit. You can tell by the nib if your high or lower. Looks like your a little high. I guess if your drilling out the middle it doesn’t matter. Great homemade lathe. I wish I had the talent.
Chain driven boat transmission? Smart thinking. Usually used to add reverse, but never thought about using one for two forward speeds!
Man i could watch metal being machined all day cool build always wished my kart had another gear as a kid now as an adult i just build em with car drivelines
Those welds will snap after a few gear changes, love the idea though. You should have added a chamfer to the inner piece and you would have been fine with a deep grunty weld. But laying a cold bead over the top to hold it together just wont last man.
Krasava Chris! Keep turning the subject,thank you.
Very good job without expensive lathe very creative
I like it :o) It’s a bit big and clunky, but it will just work :D And that’s the important bit !

Похоже и токарный станок самолепный. Это даже хорошо. Вот, например, пельмени самолепные вкуснее магазинных 😂

Roman Senn rubber gloves,you re welcome ;)
Also the long sleeves... was quite worrying to watch.
Creativity with simple things is wonderful
Very nicely done! Did you make your own lathe? That looks pretty cool too!!
I love the cooling fan on the lathe motor!
I love homemade! It shows creativity. Good Show on that transmission. Thanks for editing this video too
Everything looked real good, till I watched you use a vise grips on a nut!!!...How do you plan on shifting, or changing ratios??
If you had another collar on the drive plates with a groove, that could be used with some kind of a fork.....Good Job!!!
Very impressive Lathework machining gears......I'm wondering if you could've used a Rear Sprocket from a 3 Speed 20" Bicycle and the Shifter handle that us affixed to the top tube (on boy's bike) ? Just a thought!

I really appreciate this vid, but why not just have a CVT? it works the same and without as much wear and tear on the actual devices. I would love to adopt a two great system into my mini buggy, but I lack a lathe and other components. I do love this break down however because the details and effort you went through to create it. Thanks again and keep the vids coming.
That's it is crazy and technical. great video
Frazer Nash cars had the same type of sliding dog chain drive trans . pretty effective in their day and lot easier to change gear than the trans of the day .
Nice work! Is that a DIY lathe? Looks pretty good, though I wonder if you get chips in that exposed lead screw.
Молодец! На ходу, конечно, не переключить, но лучше так, чем никак ))
your to kool man!, i love your inovations,love that lathe you made too.
Pretty cool homemade lathe.
Did you know that 3dmotorsport sells a manual clutch kit that you might be able to use in this project? You should go and check it out, its pretty cool
4:42, You naughty boy !! That was sacrilege!
Also....sharpen your tools, your surface finish is rough as hell...
great vid but I'd put a centre in the end of that bolt if you're using it as an arbor to turn larger objects.
thats why your tool squeals so much when you turn the face of the shoulders
(just) A two-speed works for me :) It's really like a home brew 2 SPD Dog Box. Very COoL. Thank you.
This is pretty cool but I was hoping you would bust out a tig for your welds.
I've never seen the paper idea for placing your holes. I've always just laid them out on my work piece. Its a technique i'm definitely using in the future.
Outstanding work 👏👏👏
Thx for finally showing us!
Have You Seen " Make It Extreme" s video of tilting reverse trike? Just Wondering. IM SURE YOU WOULD LIKE IT. 👍🏼
very nice machine work,though it would be nice if the gear ratios were really varied like the left side is small nice,but the other one should be significantly bigger since two gears need extreme varying gear ratios for maximum efficiency in different modes but I guess it can also be done on the wheel axle gears
You must agree he has skills.
if you KEY the gear selector inline with both of the gears engagement holes, the selector will spin but you will NEVER grind when changing gears.
Nicely did it!
Absolutely beautiful.
you could have encased your 2nd 2 speed transmission so you can have the transmission parts bathe in oil, put some rollers on those pieces that engage with a gear, and you could polish up some surfaces of the transmission
Nice, but are you going to add bearings to the sections that hold the gears? The shaft is spinning inside them without bearings, that can't last long... just my opinion, others may vary.
Is that a homemade lathe? oh my God that's freaking amazing!
You might have an issue with the centre part sliding on a round shaft with only a woodruff key to stop it rotating. A square or hexagon or a spline would be better I think. Nice job though/
Super ,très bon travail !
That's the fastest, bloodless, old timey machining I've seen.
Tighten all three jaws.
Nice Work!
you made the lathe too , amazing !
Nice bit of engineering, 10 out of 10, but how do you fix it between the engine and back axle, seems an I'll suited design, sorry !
01:56 Today, I learned how steel wool is made!
You could use the lathe to scribe a circle when you're marking out the female clutch plate
Often use very sharp tools ( 2 - 3 hours of constant work ) - it makes machining speed and acuracy highest. Moreover the machine material consumption is lower.
Please don't get electrocuted with that motor and the metal chips inside : ) great video!
what is with that fan on the lathe? is that to help clear chips from the area, push them into the motor?
Nice idea! Will you be sharing the selector system build too please?
$5000 worth of tools, for a $20 transmission. =D Great job man!
Amazing skills very well done
I'm confused. Two outputs, are you running two chains to the drive axle? There has to be a better way....... I know there is a better way! The concept is good, it needs refining,
I really like the home made lathe!
Anyone who can make one with a fair amount of accuracy is cool! I like the very dangerous unshielded fan as well! Please put a shield on it, my knuckles hurt just watching it run!
Nice job, but please be careful.
Unreal it must have taken you ages to do it well done 10/10 you no your stuff bud
Dude, get that glove off when working at the lathe! It WILL be caught in the chuck jaws eventually, ripping your hand clean off !! Please, please don't do it!
then you are to stupid to work a lathe
Morten Kristoffersen don't be like jessejames and loose a pinkie haha
Morten Kristoffersen it has so much torque it will rip his arm off.
No gloves when using lathes, mills, grinders, drill presses, or any other stationary power tools.
I've seen pictures of a man get pulled into a lathe and his head crushed.
It's not pretty.
Goodco limgpu
Fuck off.
Wearing gloves on a lathe is like running a chainsaw with shorts and sandals on.
There is no reason good enough, to justify the risk.
That little metal lathe fan is deadly looking
That was dope!
You don't mess around , do you? Great work.
That lathe looks so dangerous. I want one.
@rather B welding ,can you please give me a list of the equipment used ?
I'm making a gokart using your method ,and the list will be highly valued !
Thanks in advance ,awaiting your response
Dude, I really enjoy your builds. I need to say tho, your machine shop safely is lacking big time. Never ever gloves around the chuck!! And if your shooting theses videos alone.... love the content just be safe.
You are smart i didn't thought that if its works you are the top
Can you tell me please what is the music in the last part of your video??
Italy - Brescia province - a week ago a nineteen-year-old boy DIED because of the long sleeve of his sweater was hooked by the lathe's spindle.
its too bad you cant get a set of brake pads on springs to act like a synchronizer (or even the clutch rings from a motorcycle clutch). also, a center drilled hole, with a ball bearing and spring makes for a great detent to hold it in place. might also use a centered spring to force it one way or another to help override the springs in the sync/ hold it in gear.
Maybe a live center used in the arbor would stop the runout
Couldnt you just put two of them in series for a 4 speed transmission or more formally a 2 speed with low and high? Or maybe even more than 2... I'm very curious now
How about long sleeved shirts?Lol,what until he loses a freakin arm turnin stuff on the Lathe?!!
