The holes your pins slide into need to be curved slots maybe twice as long as the pins so you have a wide widow of engagement. Then you need to put a chamfer on the edge the direction of engagement. Look up Liberty Gears faceplating operation for some inspiration. I have it done on my five speed and upshifting is butter. Downshifting requires some finesse but whatev.
That vertical tube holding up the steering wheel scares me. First time you hit something hard you will become spayed and neutered. Maybe an upside down 'U' that your legs can fit between might give those jewels some buffer of safety in a head on crash. :)
A simple mod that I think would help a lot on your shift would be a killswitch on the gearlever, the momentary type. It would allow you to cut the ignition for just long enough to make the gearshift much easier. Works a treat on Dirtbikes so why not in this case?
In portuguese Brazilian. Instale uma mola entre a alavanca e a caixa de marchas, assim ao trocar a marcha em movimento a alavanca vai até o final do curso e a marcha caso não se encaixe a mola vai fazer uma pressão continua até que se alinhe e a marcha entre. Congratulations man. God job.
Your gokart project is quite an impressive biuld - thank you for sharing your story! This video would be an excellent addition to any builder's resume.
Have you got a video that shows the details on that two speed gear system? Just like to see it and what spins and such, I've scanned through the build videos but don't care about your welding, just like to see it explained, thanks.
I like the build, and the idea. I used a Geo Metro manual trans on mine, it needed reverse since it was more for climbing. Worked out pretty good, I was even able to use a centrifugal clutch to drive it, then just left off the gas to shift. Then was able to shorten CV axles for suspension, and rear steering.
You could use a bicycle cantilever brake right on one of the gears. Doesn’t need a lot of braking force, just enough to defeat the rolling resistance of the bearings
Put an clutch on the motor to solve your problem. One of those weighted rpm related clutches. That way when the motor is idling there is no power to the jack shaft
Hey congratulations on your sponsorship that's fantastic. Like I told all the haters in the first part of your go-kart build I figured you'd have a way to get the gear shift to work. Congratulations for those of you that didn't see the previous video go-kart build number two before Your sponsorship he was showing the go-kart Natasha Ron and the gears work great anyway keep up the good work I look forward to your next bill
One suggestion for the issue of having trouble getting it into gear.... use larger holes and make it a "dog box" essentially a transmission where you just have to be close to get it into gear... it will shift rough though
Ever heard of "double-clutch(ing)"? That's what people did before synchro's! Up-shift: let off throttle with slight force on lever, pops-out, slightly press into higher gear, pops-in Down-shift: let off throttle with slight force on lever, pops-out, blip throttle, slightly press into lower gear while engine revs go down, pops-in (if you rev'd high enough) Use the clutch when you want to, but usually people do it when pulling out of a gear, and putting into a gear, but not in between. Hence: "Double-clutch" shifting. I tend to not use the clutch, at all, because I have driven several of my manual trans cars without any clutch, for over a month (total). (various failures: mechanical clutch failures, hydraulic actuation system failures, mechanical actuation system failures)
the pins are not going to slide into the holes you will need to chanfer one edge so they slide into position when spinning what you really need is friction plates ther power would be a disk and clutch plates left and right of it pull pack froce goes onto the first gear forwed and plates force onto the 2nd gear releasing the pressure on the 1st gears clutch plates
Yea like a ramp down ahead of the hole so the pins will go down enough to catch the holes. Enlarging the holes to help might cause a ton of chatter, but a ramp down would definitely help.
Make some more discs that float on your pins, and put friction material on them. This way, when you shift, it will slow down your jackshaft and allow the pins to mesh when you shift from neutral to gear. I see you have a belt drive from engine to your transmission, so just get a bigger belt and make a spring loaded tensioner that you disengage to make your clutch. You shouldn't need to disengage it to shift from 1st to 2nd, just lift when you shift. Great work! :)
Nice project man. Love to see the development of a plan to reality. Sure there is a bunch more to figure out yet. That is my favorite part of a project and like how your videos kind of tell your story. Takes allot to put yourself out there and I totally respect that.
hmmm...I think Simpson may have a good point. It seems the pins may snap if they engage at all...and if they do you may have a case of whiplash. I've considered a similar (2 or more) speed setup using car Air Conditioner clutches and operated electrically. When the shift is made power, is switched from one to the other, making a smoother transition without doing anything with throttle. The Ford/AMC ones look like they might work.
Jamm it into 2nd gear, u could become a madd truckie... or you can glide it into 2nd gear with right revs and prove you dont need a clutch. Just park it on a slope to engage 1st gear and ur away. Love your design man. 3 speed next ?? keep at it :)
I'm sure you have it figured out by now, but I would recommend putting a tensioner on the belt to act as a clutch when shifting. Put a pedal on the floor and lets pressure off the belt, causing it to stop turning (or at least slow down, shift gears, and release the tensioner clutch. Just my two cents worth. Great job young man.
That counter shaft is going to need bearings where each sprocket hub attaches. Can't have the un driven gear spinning without lube or a bearing. Might want to taper the holes in the plate to make it go into gear better.
Personally, I would have gone with a friction clutch and an over-center spring set-up. That would give you the option of doing some skids an' stuff. ;-)
As someone with a little experience with gearing without cluches, what you need is a gear syncronizer that will keep in pace in between shifting your selector gear also the pins were a good start but something that small is difficult to line up a couple hundred rpm try something with chamfered lugs that slide in and out of place easily and smoothly, wish ya luck though quite a engineered project i must say
Before I watch testing, I`m concerned. Engagement looks scary. That`s why they have synchros. I don`t know if yours will work. Could be a crash, jam engagement. Would`t last long. Maybe facing clutch discs might work better. We`ll see. See you on the other side. Sorry for the drop.
Love joy. That's what you've built. My suggestion is scavenge a cvt primary and secondary drive from an ATV somewhere. Then you will have an automatic transmission with unlimited gear ratios. Just saying.
Are you using a flux coated wire in your mig, if not: why does it produce that amount of "dust" around the welds? I've never seen that before. Oh and also: awesome build dude! :)
You need a torque converter before anything, make the jackshaft stop off throttle then put it in gear and when you hit the gas its has the clutch/ torque converter (idk).
I dont think you will have any issue with top speed bro, I notice you have a torque converter on it all ready, I tinker with this kind of stuff some and with just some quick figuring you will go plenty fast. with the way your steering is and the seat not having much side support it will be kinda hard to control with top speed, I made the mistake once of building one, but my gear ratio was to the point it didnt even have the power to get to full speed with the engine I had, lol. but with your 2 speed trany I think you will have the power, lol I love this stuff, nice build and good luck man!
Just a tip turn up your wire feed a bit.. Looks like the wire is going to slow and your probly going through alot of wire. I use to do the same thing till i got ballsy and cranked it up
This is awesome I wonder if it would be possible to do something like this on a mini bike put a sprocket on each side of the back wheel high and low gear that would be sweet
Not sure welding on a woolen table, with a wooden floor under it, in a wooden building, is something I would continue to do, but again what do I know? Just another random viewer opinion!
use a Plate with springs on 1 side and Course and paper on the other to create a makeshift clutch/ synchro. Or a inner and outer cone to act like a synchro. looks good
The holes your pins slide into need to be curved slots maybe twice as long as the pins so you have a wide widow of engagement. Then you need to put a chamfer on the edge the direction of engagement. Look up Liberty Gears faceplating operation for some inspiration. I have it done on my five speed and upshifting is butter. Downshifting requires some finesse but whatev.
I believe something like that Is called a dog box on full size vehicles
That vertical tube holding up the steering wheel scares me. First time you hit something hard you will become spayed and neutered. Maybe an upside down 'U' that your legs can fit between might give those jewels some buffer of safety in a head on crash. :)
Kind of expected you would paint it while it was disassembled.
A simple mod that I think would help a lot on your shift would be a killswitch on the gearlever, the momentary type. It would allow you to cut the ignition for just long enough to make the gearshift much easier. Works a treat on Dirtbikes so why not in this case?
S.Frimodt wouldn’t be hard to wire either
perfect
Ii8iiiiiiiiiiiiiiike
Exselente los felisito. Grasias por videos istructuvos los admiro muy presiosos Dios los Bendiga

Muito bem pensado
Парень очень рукодельный! Молодец!
Your a beast dude. Love watching you build with no paper plans.
Your gokart project is quite an impressive biuld - thank you for sharing your story! This video would be an excellent addition to any builder's resume.
I like especially your videos about the construction of the lathe
I believe the fan at 1:29 is shaking it's head saying "DON'T DO IT! Lol!!!
But what flavor is that frosting?
Wow
It will be interesting to see how it shifts and what, if any, changes you decide it needs. Nice job!!
Have you got a video that shows the details on that two speed gear system? Just like to see it and what spins and such, I've scanned through the build videos but don't care about your welding, just like to see it explained, thanks.
Hola Amigo me gusta el video aprendo de el, Gracias por compartir saludos!!!
Such a nice project by the way the first one here

Worked out pretty good, I was even able to use a centrifugal clutch to drive it, then just left off the gas to shift. Then was able to shorten CV axles for suspension, and rear steering.
Just have a belt with a tensioner as a clutch to spin the shifting plate for smoother engagement maybe?
like a self propelled mower
это машина вапше класс 👍👍👍👌👌👌 мне понравился это видио👌👌👌👏👏👏
You need to do a complete video on the 2-Speed trans and explain how it works!!! Cool looking go kart and keep up the great work!
that fan is in time with the music.amazing
Great video! I really respect your ingenuity! homemade lathe and all. you rock!
You could use a bicycle cantilever brake right on one of the gears. Doesn’t need a lot of braking force, just enough to defeat the rolling resistance of the bearings
I like that steering wheel go get a can of flat black rattle can for $1 and paint it
2 hr later his shop burns down, welding on all wood surfaces kinda risky man, but I love these typ of vids so thanks for uploading! just be careful
AK Custom unless there is flammable stuff or paper or stuff like that, it would take quite a lot of welding to try to get a fire
This guy man if he hifs it with a torch for 5 mins mayb gt some smoke chill osha
Fajny.
Put an clutch on the motor to solve your problem. One of those weighted rpm related clutches. That way when the motor is idling there is no power to the jack shaft
Kevin Desormeaux centrifugal clutch
Kevin Desormeaux the torque converter on that shouldn't move when it's in idle
Genius man. I bet you are a transmission mechanic.? The seat is awesome. 👌🐸
That's a curious design! Well thought!

Really enjoyed this video without the bad language. You're smart . Keep up the good work!
I really like your 2 speed idea. Make a disc brake to stop the shaft when in neutral. could you have used planetary gears out of an old transmission?
Твой канал это то что мне нужно!!
that inverted stand fan tho
you is legent of cart😱😱😱☺😱
One suggestion for the issue of having trouble getting it into gear.... use larger holes and make it a "dog box" essentially a transmission where you just have to be close to get it into gear... it will shift rough though

no cars have a single plate clutch only motorcycles have a multi plate wet clutch
Yea like a ramp down ahead of the hole so the pins will go down enough to catch the holes. Enlarging the holes to help might cause a ton of chatter, but a ramp down would definitely help.
David Simpson my thoughts exactly david, how in the hell does this dufus think those pins are going to magically enter those holes?
there are clutches that bolt to the output on lawnmower engines with a sproket on them. and they aren't crazy exspensive. so could simply add a clutch
centrifugal clutch won't work here.
Make some more discs that float on your pins, and put friction material on them.

this fuckin beat is FIRE!!!
do a drag build 👌👌😈
YOU WACH CARS AND CAMERAS
Kenneth dolberry ;):))

I like the song that goes beep, boop boop beep beep.

çok güzel araçlar yapıyorlar ama motoru bozulsa hiç iyi olmaz
Little "durability test" of your welds too, looks like they held. :D
Have all the videos of you seen and will continue to look, you can learn a lot from you. Thank you

that is fricking good
Show de bola meu amigo ... vou fazer um ok thank you
that is too cool
I agree. You might want to put lead in grooves on each hole. Otherwise really cool piece.

Sychromess...just kidding I really enjoy your machining and inventiveness.
Need slotted holes for the drive and Ackerman angle in the steering.
Love joy. That's what you've built. My suggestion is scavenge a cvt primary and secondary drive from an ATV somewhere. Then you will have an automatic transmission with unlimited gear ratios. Just saying.

muito bom ! qual tipo de tubo e usado na fabricaçao do kart?
the device that slides between the gears is called a synchronizer. it works like a regular manual gear box except it has pins instead of teeth
That was cool.... just a new lathe and my wheels are turning...
You need a torque converter before anything, make the jackshaft stop off throttle then put it in gear and when you hit the gas its has the clutch/ torque converter (idk).
I dont think you will have any issue with top speed bro, I notice you have a torque converter on it all ready, I tinker with this kind of stuff some and with just some quick figuring you will go plenty fast. with the way your steering is and the seat not having much side support it will be kinda hard to control with top speed, I made the mistake once of building one, but my gear ratio was to the point it didnt even have the power to get to full speed with the engine I had, lol. but with your 2 speed trany I think you will have the power, lol I love this stuff, nice build and good luck man!
genius !
Just use a sheer to engage the gears early so they spin at the same rate. Only problem is you'll get a nasty jerky forward
good jov
Nice yr Electric Fan Broo...
:D
i want to know more about the engine , can i repurpose a lawn mower eingine to run a go kart and will it have forward and reverse
Brilliant shed building with a little budget 👍
Great job looking good
vari good
awesome!
Dude, put something under the cart and get up off the floor! Otherwise, great vid.
just welding rods to bolts isnt a great idea. Weld a tab onto the rod then put a hole through it and bolt it down
I liked the bolts to rod construction. Its simple and effective. No need for accurate measurements.
Very good brother
You need to synchronize the sprockets to the drive wheel. You could build two simple synchromesh cones on a lathe.
Just a tip turn up your wire feed a bit.. Looks like the wire is going to slow and your probly going through alot of wire. I use to do the same thing till i got ballsy and cranked it up
That drop hurt me so bad..
This is awesome I wonder if it would be possible to do something like this on a mini bike put a sprocket on each side of the back wheel high and low gear that would be sweet
You do great work. Can you consider building a tadpole trike?
Very cool designs
Wow
The shifting becomes easier the more space you got. Best ofption had been to use bigger holes in the loose wheels or even cut slot holes into this 👍
Incrível, show de bola camarada
Not sure welding on a woolen table, with a wooden floor under it, in a wooden building, is something I would continue to do, but again what do I know? Just another random viewer opinion!
Only thing worse than having your work fall off the table is leaving your bottle of gas open all night and not realizing it until the morning
I'm starting to think that fan is in denial of your videos but great videos otherwise
its trying to tell him to stop welding in a building that's 100% wood lol
Patrick

Ok maybe but.... he has more than 1 millions view.....!!
SASHA
I'd appreciate if you could make that thing with a mud guard. I'd buy that myself personally..... 👍
bonjour;ça me plait votre travail,est ce que cette boite a vitesses marchera avec un motoculteur?merci
Taip supratau padarei dvi pavaras. Bet riedant ratams neperjunksi. Ačiu patiko 👍
Nice
Muito obrigado por me responder, e o portugues está muito bom!!!
use a Plate with springs on 1 side and Course and paper on the other to create a makeshift clutch/ synchro. Or a inner and outer cone to act like a synchro. looks good
what happened to your lathe? Are you using it? Did you improve it? Are you intending to improve it?
thanks for the answer. I am more interested in the lathe project than the karts and I don't want to watch all videos to find the bits about the lathe.
rol eic the lathe is doing great I just haven't got around to doing a new video about it yet.
great. I am looking forward to it.
You should build 2 speed transmission kits for purchase for those of use who have access to welders but not lathes
