i was a fabracater for years and take it from me...you are a very talented young man.. great work..very impressed..also to all the young people that watch these vids.. see what is possible when you don't eat tide pods... lol great job young man
man I am 59 yrs old been building stuff my whole life...and good stuff too, and I have still learned a ton from you the way you figure out how to do things shows your very intelligent man, koodo's to you, love your videos.
you've built a lot, huh? can you tell me anything about making a high torque transmission for my kart that im tryna build? any designs? can I improvise, since my setup is electric?
your fabricating skills are seriously impressive and effortless. you seem to make go karts and other motorised vehicles so easially. i love your work!!
Might want some bearings on those gear setups for longevity. Without bearings the shaft will get a groove in it eventually and those hubs will be loose and floppy like.
it's a great idea but if I can recommend a few modifications for future build: some sort of soft bushing or bearing on the output gears ( as I can only imagine all the wear they get without) and putting sacrificial brass sleeves over the 1/2" drive pins to prevent them being chewed up after time. Other than this there is not that much more I can give out about as it is such a great simple design. Well done.
Awesome job as burdman has stated. I am a veteran fabricator and you have made some interesting machines. I would personally find the dimensions and go get this stuff cut out bu a waterjet cutter and use a higher grade steel other than mild steel
i like the lens effect your camera has when your welding....very nice. also for milling in your setup look at getting a carbide burr double cut 1/4, 3/8, 1/2, 5/8, etc..
what you need to do next time is drill the middle of each slot with the same bit you drilled your kog holes, on the 22.5 degree radius of each 90 degree section of the circle graph the same distance from center as the rest of the holes its hard to explain but the offset this third hole has in between the kog holes will be equal to the convex of the slot you desire (+/- some thousands) then mill out the tiny triangles. other than that awesome video! 22.5 is half of 45 is half of 90
I wood make the clutch dog have two parts. Have the main part (Dog) fixed to the axle. Then have another section with the pins (clutch) slide on top of the clutch dog as one unit. This piece will lock the sprocket and the clutch dog together as one. I see major issues sliding the whole clutch dog while relying on a single key-way to hold up under the axles rotational force. The potential for the clutch dog to bind on the key, preventing it from sliding, is very problematic. I love the concept.
Question: will the clutch dog actually slide on the key-way that easily when there is torque on the axle? Isn't the clutch dog going to bind on the key, preventing it from sliding from one gear to the other?
Great video bro. I'm in love with this creation. I'm actually thinking on how to create even a 4 speed plus reverse gear using this simplified yet clever idea.
A Pro Cut table top milling and drilling machine, even the larger ones that can easily handle decking motorcycle heads, end milling operations, fly cutting etc... and uses all standard milling fixtures and hold down camps, has an R8 spindle collet, and a variable speed belt and pulley drive can be found used in good shape for $500 to $800 with some tooling and fixtures usually and new in the $1200 to $1500 range. They aren't Bridgeports but from the stuff I've seen you do it should handle your needs and takes up a lot less room than a big floor model milling machine that's beyond overkill for 90% of all home shops. And in a pinch can safely be moved by 2 people without a struggle.
You could use the first 2 speed on the lathe to give it 2 speeds without changing the belts. If you added a set of gears you could give it reverse as well.
Great project... The slots are a good idea... I was wondering, after watching previous videos for this project, if you considered making 'ramps' on the leading edge of the slots to assist with engagement? Thanks for sharing your project.
Nice video, good job. I want to make a transmission like this but I was wondering if you could tell me what diameter your clutch dog pins are and the diameter of your 4 steel plates? Thank you!
watching all of your videos and making sure to like every one of them. Man, you got skills, amazing job, you and your humility inspire me and probably alot of people to do our stuff..... people like you move the world!!
OK, You know how sometimes we do something really stupid ..... we all do it. But for Gods sake take that allen key out of the bolt on your slide table it is heading for your chuck, I am a professional fitter and turner and I have seen many avoidable accidents with serious results. I love your videos and you have given me some serious ideas. Keep it up stay safe.
Here's an afterthought... The milling between the holes doesn't need much precision so you could use a cheap plasma cutter. I'd still spin it on the shaft and fix the plasma cutter with some clamps. I've had older good ones and newer cheap ones and the advancements in high power semiconductors makes today's super cheap plasma cutter work just as good as the older quality unit.
I know you probly have a solution for the actual clutch, what for engaging the whole set up to reduce wear on the transmission itself and to allow for smoother shifts and taking off from stops smoother, (I know the power loss is greater with a belt) but, if your input sprocket was a belt, you could in theory just make a swing arm clutch like that of a lawn mower and still have your gears. Just a thought, but I absolutely love your idea otherwise and I really enjoy watching your videos. You honestly are one of the most talented UA-camrs I've seen. Keep doing what you're doin man!
Cool as always, but wont the hubs from the sprockets that arent connected be slipping on the shaft the whole time since the axle would be spinning it? That would cause a lot of wear, wouldnt it?
Best idea ever . How much do you ask for making one without gears on it so i can put on the right gears myself . And if you would make one for me do you also send to the Netherlands ? Greats and waiting for your reply .
Jay Leno has a race car from the 30s (or even earlier) that has a 4 speed chain/sprocket crash box trans-axle. The chains run from the shaft the engine drives to the axle, no extra shafts or chains. I wish I knew which video it was in, the most I can recall it was one of the "whats going on in the shop" type videos. Maybe one of those with his bud Dennis Gage. Jay did say it was bulletproof. An eyeball on that might give you some clues for improvements to your design. Four speed baby!!!. Maybe try just a belt tightening clutch with that 4 speed, maybe with those extra ratios you wont need the TAV.
Just a thought, couldn't you have this as the rear axle, drive both of the current "output" sprockets directly from the engine? This would eliminate the 3rd "input" sprocket. It might make it more economical to build. I'm sure the cogs are more than capable of handling the extra torque after the gear reduction. AKA Switch the shafts around, this is now the axle and the jackshaft is a solid rod with 2 sprockets welded to them, driven directly off the output of the CVT. Unless you cannot get the right ratios without that extra sprocket...
Love the videos! Do you still use flux core? Because argon/co2 makes it so nice when you can finally upgrade. I believe chamfers on your plates to shaft will provide a MUCH stronger weld! Look into this!
You have a lot of talent young fella! Are you a machine operator, engineer? You should be a metal shop teacher! Good job making things work out with home made fixtures and equipment.
For the kart that you're currently building, about how much would it cost to build one of these 2-speed tranny's? I plan on starting a kart build by the end of the year and I really like the look and size of your current design. I have the welder and all the tools I need for the build except for the lathe. Any advise or suggestions you might have would also be helpful and welcome.
Looking to build one for my drag mini bike but was wondering what keeps the output gear pieces in place so they dont unwantingly move into the clutch dog
This guy never replies to comments. Using collars fixed to the axle on the outside of the sprockets will prevent them from drifting outward when the clutch dog gets shoved into them. The chains on each sprocket might be enough to keep them from drifting into the clutch dog. Ideally, collars on both sides of the gear sprockets should be used. But, hat would require some alterations to the clutch dog to slide over the top of the collars. I'm more concerned with the clutch dog binding on the key when torque is placed on the axle. That is what connects power from the axle to the sprockets. Key-ways on top and bottom of the axle may be needed. Good concept.
I was inspired by you idea but i will be using manual clutches from 3dmotorsports and a subaru rear diff. The out put is going to be coupled to the diff which is already 4:1 with my set up it will be 6:1 in high and 10:1 for low. Going to be using it to pull a boat trailer from the camp to the dock
I'm building a dune buggy about the size of your gs500. I'm using a Suzuki gsxr 750 how did you set up your clutch and shifter I have an idea of how to set it up but I want to know how you did it.
Can anybody tell me? The sprocket that is not engaged, it is spinning loose on the jack shaft at a different rpm than the drive sprocket from what I can tell. Are there any problems with the one that's not engaged wearing away the jack shaft at all?
hallo;Moin aus Germany;ich bin ein großer Bewunderer deiner baukunst,habe das Mini Qad nach gebaut, und es leuft super. ICH MÖCHTE gerne wiesen welche masse die Scheiben deines Getriebe haben,und wie groß die Zahnräder sind ( wieviel Zähne ) mach wieter so ich bin Begeistert. Suuuuper;........
Instead of using cogs to shift gears why don't you use helical crown gears? I think helical crown gears will have an easier bite and smoother transition.
I am in the process of building an electric kart with 2 18v 'fuel' drills. itll need a transmission to handle all that torque. can you give me a parts list for this? or can I buy yours? ? I don't know of any other way to get myself a gearbox...
be realy CAREFULL uding gloves near a drillpress lathe or mill hitting it with bare hands causes pain and prolly some skin loss nut youre able to pull away, hitting it with a glove will pull youre whle hand intoo the machine before youre able to do anything use a vicegrip or a vice to hold the part
sumting simulair actually happened to me too , it kindah opens youre eyes about youre vunerabilliyty , it was 1/10 of a second of lapsed concentration but it was all it took
i was a fabracater for years and take it from me...you are a very talented young man.. great work..very impressed..also to all the young people that watch these vids.. see what is possible when you don't eat tide pods... lol great job young man
LOL Awesome Comment !

Proper oldschool fabrication man. Love it. The way you get things done with limited machinery. Creativity and fabricaton skill. Real talent.
your fabricating skills are seriously impressive and effortless. you seem to make go karts and other motorised vehicles so easially. i love your work!!
rather be welding you should make some of these 2 speed transmissions and sell the to people who would like one of their own
Might want some bearings on those gear setups for longevity. Without bearings the shaft will get a groove in it eventually and those hubs will be loose and floppy like.
if you drilled between the holes it would give you less to mill out
David Simpson I would've done that then got out my files
it's a great idea but if I can recommend a few modifications for future build: some sort of soft bushing or bearing on the output gears ( as I can only imagine all the wear they get without) and putting sacrificial brass sleeves over the 1/2" drive pins to prevent them being chewed up after time.

Young gun, it's great watching your work. Keep it up, you do an awesome job, brother!
making this go-kart transmission really cool I can imitate it, thanks for the tutorial
If only I owned a lathe lol. Still cool as hell!
I think that he built that lathe tbh...
Buy a South bend 9c $500- 1200$....save and buy it, they last for ever, some even been around since the 1920s.
Awesome job as burdman has stated. I am a veteran fabricator and you have made some interesting machines. I would personally find the dimensions and go get this stuff cut out bu a waterjet cutter and use a higher grade steel other than mild steel

and i guess i didn't see you used 30 degree angles, so: "on the 15 degree and 75 degree radius of every 90 degree section."
15 is half (or centered) of 30 is 1/3 of 90
beacause (07:33)

You have so much talent.
Can't wait to see it in action!
Have you thought about doing a simple syncro arrangement with some kind of friction disk to help match input shaft speed to ground speed?
Question: will the clutch dog actually slide on the key-way that easily when there is torque on the axle? Isn't the clutch dog going to bind on the key, preventing it from sliding from one gear to the other?
Have you ever did or thought about putting a 2 speed gear in a large frame mini bike? And would it work and fit properly without clearance issues?
That allan key was a bit close to the laith at 2:28.cool job.
That Allen wrench sticking out of the lathe was slowly killing me the entire time it was there. I'm glad we survived.
Great video bro. I'm in love with this creation. I'm actually thinking on how to create even a 4 speed plus reverse gear using this simplified yet clever idea.
You got skills dude :)
Experimental Fun hanomag
If you make an attachment for your cross slide and tool post, you can use your lathe as a mill.
A Pro Cut table top milling and drilling machine, even the larger ones that can easily handle decking motorcycle heads, end milling operations, fly cutting etc... and uses all standard milling fixtures and hold down camps, has an R8 spindle collet, and a variable speed belt and pulley drive can be found used in good shape for $500 to $800 with some tooling and fixtures usually and new in the $1200 to $1500 range.

And in a pinch can safely be moved by 2 people without a struggle.
Is that a file mounted in a scroll saw at 9:07? I've never seen anything like that.
yep it works great
Very cool!
I have never seen a file used like that either... Looks like a great idea.
You could use the first 2 speed on the lathe to give it 2 speeds without changing the belts. If you added a set of gears you could give it reverse as well.
Great project... The slots are a good idea... I was wondering, after watching previous videos for this project, if you considered making 'ramps' on the leading edge of the slots to assist with engagement? Thanks for sharing your project.
this guy is hella smart! good thinking
Could you add a centrifugal clutch instead of a fixed gear to the jack shaft to act as a clutch for shifting between gears?
for slots i drill out as much as i can then use a flat file. another option is the cnc plasma shop in town will whip one out for $5
Nice job on the mill work..
Nice video, good job. I want to make a transmission like this but I was wondering if you could tell me what diameter your clutch dog pins are and the diameter of your 4 steel plates? Thank you!
Nice job, a lot of work, I am looking forward to see the next parts.
Awesome ,hands down the best channel of this kind of channels
You should build a 4 speed monstrosity with 2 of those someday. Imagine all the chain rattle good god
Alex King probably wouldnt be worth all the rotating drag unless he was using something like a 670 predator
watching all of your videos and making sure to like every one of them. Man, you got skills, amazing job, you and your humility inspire me and probably alot of people to do our stuff..... people like you move the world!!

Your 2 speeds are getting better design each one you make you'll have them down pat i see you pretty much already do lol good job on this video buddy.
Realy nice transmision
U should try to make the clutch dog with sealed bearings so that it doesn't wear down the axle.
You could use the lathe to cut the slots. Good vid
Wow its been awhile i remember finding you back when you were small, sponsored! 80k+ subs! Congrats man i loved your channel
Hey man
Why dont you make an attachment for your lathe for milling the lathe can handle big stuff
I know you probly have a solution for the actual clutch, what for engaging the whole set up to reduce wear on the transmission itself and to allow for smoother shifts and taking off from stops smoother, (I know the power loss is greater with a belt) but, if your input sprocket was a belt, you could in theory just make a swing arm clutch like that of a lawn mower and still have your gears.

Well Thought out design and Great Work!! Why couldn't you gang drill the disks? wouldn't the holes line up then? Liked!!
Are you going to add a differential to this thing someday?
So triggered by the hex wrench left in the tool post of the lathe, just a little closer to the chuck and bam! Instant flying steel rod of death
Just a thought, couldn't you have this as the rear axle, drive both of the current "output" sprockets directly from the engine? This would eliminate the 3rd "input" sprocket.

Needs a clutch brake but very nice work I hope to make one soon :)
How do the gears line up to engage?
you should make a belt sander
Love the videos! Do you still use flux core? Because argon/co2 makes it so nice when you can finally upgrade. I believe chamfers on your plates to shaft will provide a MUCH stronger weld! Look into this!
what sizes are the metal plates with holes
Dude you need a rotary vice and the good lock studs then you could pull off the slots with out the chatter
Here in Brazil you would be called "professor pardal"... kkk
Great job, very interesting 👍
very interesting, love the file in the scroll saw!! have you ever considered making a real mill?
Congratulations great idea great project
Any thoughts on a reverse gear
would it be possible to use this setup, but instead of two forward gears have it be forward and reverse?
should definitely sell the transmissions online, could probably sell through gopowersports
i just had a thought why couldn't you use cables like the reverse adaptor for go karts
You have a lot of talent young fella! Are you a machine operator, engineer? You should be a metal shop teacher! Good job making things work out with home made fixtures and equipment.
Let me know if you ever want a job here in Rochester NY. You would get hired and paid well....
Such great work keep it up can't to see going
I have a quick question about the laith.. how often do you have to replace the cutter thing??
For the kart that you're currently building, about how much would it cost to build one of these 2-speed tranny's? I plan on starting a kart build by the end of the year and I really like the look and size of your current design. I have the welder and all the tools I need for the build except for the lathe. Any advise or suggestions you might have would also be helpful and welcome.
you could use the lathe as a milling machine
getting good on the lathe man...
have you noticed any problems with the 2 speed at high rpms i need to run one at 4000 rpms in somthing with tracks
Had to give you a comment like what your doing 20 yr small engine mechanic here but hey how about a 3 or 4 speed ?
I was just curious have you ever tried a centrifical clutch instead of a TAV? I was jist wondering if that would make the shifting easier or not.
Put third speed gonna be fun
Have you every thought of making a 3 or more speed transmission?
For your second gear try switching the gears
thank you for video sir. good job. please you give thr diameter of your transmision, please reply
I couldn't take my eyes off the allen wrench on the lathe

kerry what subaru rear diff are you talking about?
Id wager rear diff r160 also used as an early Nissan/Datsun diff
This kid needs a tool sponsor!!!!! Like yesterday
What, no reverse?! I'm kidding, great job dude!
I'm building a dune buggy about the size of your gs500. I'm using a Suzuki gsxr 750 how did you set up your clutch and shifter I have an idea of how to set it up but I want to know how you did it.
Show it to us working I see the concept but how do you get to stay in the gear once you're going on at work its way out of gear
Can anybody tell me? The sprocket that is not engaged, it is spinning loose on the jack shaft at a different rpm than the drive sprocket from what I can tell. Are there any problems with the one that's not engaged wearing away the jack shaft at all?
do you think your 2 speed will hold up to a 22hp in a tracked vehicle
Video getting better and better :)

Could you not drill 2 more holes for material in between to cut down on the time milling slots ?
Could've been done with the lathe as well I think.
Use your lathe as a mill. It can be done pretty easily.

Great work!
BTW Your two speed is a much improved design over the one you copied.
be realy CAREFULL uding gloves near a drillpress lathe or mill

Hello!
What kind the welding machine? gas type? no gas type?
A better idea would be to just take out the studs in the hub and have ur gear box like that
