Since these engines only run clutches or torque converters, they don't accept side loading the crank very well. They don't have much more than a simple washers or shims to locate the crank. The way that clutch applies there will be a constant side load on the crank and will probably wear the side of the case out very quickly.

Although NOT a centrifugal clutch I definitely like your first idea, very well thought out and well presented, even though I had my sound turned of while watching the video, it was so well done I could build one just by following your video. By the way, you can also modify a small motorcycle's or even a moped's front (or) rear drum brake as long as it has dual leading shoes since they are very light and might cost anywhere from five to twenty dollars depending upon where you buy it, yard sale or motorcycle swap meet; I did this about twenty-four years ago for my son's mini bike when I couldn't locate a centrifugal clutch anywhere in my area, and I don't like to order on-line since more often than not I've not received what I ordered. Take a close look as they are physically built the same and doesnt take a lot to convert it - mine was made from a '65 Honda CB72 250cc - which took the better part of two or three hours of fitting and finagling before it locked-up properly, but when it did was very impressive considering how much larger it was than a standard go cart clutch. Pretty sure you could do this easily in a couple of hours with the tools you have available.

Love your ingenuity! From one junkyard engineer to another, very well done. Thank you for sharing and the ideas. My grandchildren will also appreciate your work. Thanks again.

I agree with Willie about the loading of the crankshaft bearings. Option 1' s problem is that the load pushing axially along the crank will cause issues, but I would be more concerned about the cork destroying itself very quickly. You could make the clutch disc float on the motor shaft such that it slides with the key transmitting the torque, add a bearing and linkage to squeeze the plate together but the cork is the weak link. Maybe leather instead or leave one side bare metal and weld 2 disc brake pads to one plate as the friction material. Option 2' s problem, besides the side loading on the crank is that I would think the motor shaft might just burn up the tire where it touches due to friction if the tire fails to move. This design has potential though if you add a 3rrd tire and wheel fastened directly to the motor shaft. Then allow the other tire to pivot like your second tire so that both pivoting tired squeeze against the middle tire and balance any sideways force on the tire fastened to the motor. This would also increase the surface areas of the clutch contact points ( now rubber tire to rubber tire) which dissipates heat better and provides more wear life. Let us know how long your original designs last and if fail quickly, try some minor modifications.

Save all this trouble and time and use a 50cc motor bike engine, has a built in clutch and chain sprocket 🤔

Not a centrifugal, but very well done! It shows in a simple way how a clunch works. Congratulations!

This is not a centrifugal clutch, but one of the best automatic clutches I have seen

Meus Parabéns Ficou Ótimo.Eu estou Tentando Fazer um Carrinho e estava sem Nenhuma ideia como Fazer Muito Obrigado pela sua Dica.tchau Deus te Abençoe 🙏

Great video.... it’s great to see home made go-carts....!!!!! 👍👍👍👍👍

Strictly speaking, clever as they are, these are not centrifugal clutches, they're cable operated in conjunction with the throttle - ingenious though! Well done.

Thanks for watching this video 👉Subers yt

Good job

Ese trabajo parece fácil por la edición del video, pero no es así, se requiere de mucha cautela y precisión para su ensamblaje. Es un gran trabajo, muy buena creatividad y profesionalismo.

I definitely think that both ideas are amazing but I think the setup with the 2 rubber wheels is probably more reliable. Very smart fellow!🙂👍🙏

Cool video 👍 0:00

Wow Wow

THANKS 4 FOR SHARING U TALENT

Awesome Video and BRILLIANT MIND

Interesting ideas.. Thanks for sharing Watching here Ofw taiwan Doi Jones jhj channel 🔔🔔🔔

Very good at modifying the car.

Bravo my friend great food for thought i will have to remember this peice of engineering simple and very effective just alittle work thanks.

Bagus 👍👍👍 tp terlalu rumit ... Kurang simpel jd susah utk di lakukan /memahami

Good job fabricating these rube Goldberg drives. I don't know where in the world you are but in the US I can by a 3/4 drive centrifugal clutch cheaper than I could buy all the pillow block bearings, sprockets, metal plates, nuts, bolts and chain you used.

Amigo tenho uma idéia mais fácil e de melhor manutenção... Coloca um diferencial na ligado com correntes a saída do motor, liga uma das saídas do diferencial (que vai nas rodas) no sistema de transmissão.... E na outra saída acople um freio a disco de bicicleta. Pronto... Quando ligado e tração vai pra roda livre, no caso, o disco de freio... Quando vc freira a tração passa para a transmissão... 👍👍👍

This is amazing just what I was looking for. Cheers from Canada.

Mantap bang... saya juga lagi bikin go kart .😊🙏

Good

eres el mejor chapusero que existe hermanito

Nice

Fabricación casera pero trabajan con un torno...como si en todas las casas hubiera un torno!

I have a few Max Torque SS 3/4 shaft, 10 tooth clutches sitting around that would save you a whole lot of time and money! Made in USA still too.

Muy buen proyecto y los frenos

Its good job

Very good build & video. I think I would reverse the clutch operation linkage to releasing the pedal to engage drive rather than press pedal operation.!!

Of course, walking does it somehow. But a motorcycle engine + transmission is much better!

Muy bien hecho, simple y muy practico, el primero no es centrifuguo, el centrifuguo usa otros principios , es un clutch de presion , funciona por presion-friccion,el otro es de contacto, algo cansativo y menos efectivo tambien, ambos buenos proyectos ,felicitaciones.

muy buena idea yo fabrico cosas esta idea me dio muchas m as ideas grscias

Cool

Excellent work done 👍

Excelente vídeo mi apreciado amigo, saludos desde Colombia.

Excelente, muchas gracias x esa idea, hare uno también

claro que o prazer se fazer é algo que nao tem preço, mas uma embreagem custa menos que o gasto de fazer

Nice low tech ideas

How well will the cork facing hold up? How was exact axial alignment between the two clutch faces achieved? I don't think centrifugal clutch is the correct name for either of these designs. A centrifugal clutch engages when sufficient rpm is achieved requiring no direct operator control other than throttle.

First version was not very good, the second version is a lot better. Keep learning and experimenting and you will be making awesome things very soon!

El seguro de la cadena debe encajar del lado contrario al sentido de giro para que no se salga.

Tuyệt vời quá bạn 🔔🔔🔔

Muito legal seus projetos.

Good 👍😁

Someone buy this man a clutch.

Bien echo felicitaciones

I feel like I would like it better to run the cable like a car always connected and press in to open. Maby hook a locking thing to keep the clutch in when starting or just at idle. Great ideas I always wondered how to make a diffrent type of clutch. Thanks sir

Buenas tardes, muy buen trabajo amigo, solo que me queda la duda del material que usas entre las placas de metal me podrías decir que tipo de material es??

Un clutch casero para una bici moto? Puedes hacer esta idea aplicada a una bici moto? Gracias

Работают натруженые руки, а катается молодой, задумано интересно, но все жиденько, ненадолго.

top

Solo una observación todo va soldado o la mayoría de piezas y si se tiene que cambiar algo por alguna falla ? Creo que sería bueno combinar soldadura con tornillería y los frenos o como lo detienes cuando te toca el rojo del semáforo

Nice one

Amei o vídeo , parabéns.

Very Nice!!!

Very good

The ground/earth path for the welder should never go through bearings. It appears it did on the engine once and on the drill press once.

Beautiful work excellent job

Nice build

Chou👍

if you use gears instead of chains it will be better. You make it very beautiful. Thanks for sharing. 👍👍

Crees que haciendo una caja reductora de 20 a 1 me pueda con 350kg ese motor?

bom..dia.aí.pra.você. parabéns.pelo.trabalho maravilhoso.

This is definitely not a centrifugal clutch. And I think you should reverse the cable setup, so you push the pedal to disengage the clutch. Who wants to hold the pedal down all the time? Still cool though. I’d like to see more manually actuated clutch options. The 3d motorsports manual clutch is more like an on/off switch and hard to slip. Maybe fine on a kart with some practice but sketchy on a mini bike with a 6.5hp engine. Every launch you either stall it or wheelie it.

number 2 the easyest clucth

Nice Clutches But Neither are centrifugal. A centrifugal Clutch won't need cable or pedal. Centrifugal clutch engages by engine speed up. Thumbs up, good designs on both though :)

Two ways of making a MANUAL clutch, no centrifugal clutch in this video.

@16:59 my favorite part HAHA

First of all that is not a centrifugal clutch .I is a manually engaged clutch and that being the case you could have saved yourself a ton of work and money and most importantly adde weitght by purchasing a centrifugal clutch , which by the way ENGAGE AUTOMATICALLY when the engine has reached the correct engine torque and hp output band. Moreover centrifugal clutches manufactured today permit quick change chain sproket selection so that you can tailor the kart for top speed or off line speed ..nice work

Mantap boss que

La idea esta excelente, pero no debe ser la fricción corcho contra corcho, porque se desgranara en poco tiempo, Los cloches de moto es colcho contra disco liso de acero, me gusta la idea, espero que los que saben, se den cuenta de mi opinion.

I like it

Just a heads up but I noticed that you put your master links in backwards

😉😉😉😊😊😊👍👍👍👍👍

If you price the four pillow blocks, tubing, and all the time involved the price of a clutch is fair. Nice build all the same.

very nice

Quedaría mejor al rever Que el resorte una las ruedas y al usar el embrague que las separe Al soltar el embrague que se unas para no ir asiendo fuerza después

Very clever

Two good ideas for clutches but neither are centrifugal.

Bravo philipo 🇩🇿🇩🇿🇩🇿

Parabéns cada dia com mais ideias lindas.

I am not being funny, but you need to weld things properly, put a decent seam, those little spots won't hold. Some of those spots won't even be welded as you don't leave it long enough to heat up.

So, do I have this right? One foot operates the throttle. The other foot, instead of a brake, operates a clutch that serves no purpose? How do you stop? You went through all that, for this? You can at least make it useful. Clutch for that motor is cheaper than buying four pillow bearings. Why not make use of that clutch and add a second gear?

ti voglio bene fratello

Nice video...really like it from philippines

Why use the drill press to file down a shaft when you have a lathe that is designed for doing such tasks? You used the lathe to bore out the sprocket. Otherwise good work.

Not sure why the first setup used 2 sets of gearing. The small gear on the clutch pad shaft could have gone right to the axle gear.

Khi ép bố là nhông sên bị lệch. Nên chế chốt răng khớp

Nice, very nice indeed.

Excellent

You call it a centrifugal clutch, it's a normal clutch, the centrifugal clutch is an automatic clutch it uses centrifugal force of spinning, and here you just use the force of your arm to engage it

This looks a lot more expensive and complicated than purchasing a centrifugal clutch off of the internet.

This very interligent

nice video, hands on fabrication of a toy cart.
