Motorized go-cart (How to) - Duration: 19:54.

Hey folks, great you're watching again!

How do you like my excellent bargain!

a go-cart.. but..

It doesn't has cranks

that doesn't drive well

but we might have an engine which might fit

that's convenient!

a lot of you asked me

Show us how to motorize a go-cart

This has an engine

Good! And we don't need to mow the lawn for a while

Soo.. that disassembles quick

This is an ideal engine to put on a go-cart

an advantage of this engine is that it has a horizontal crankshaft

it's like this

many lawnmower have a vertical crankshaft

it goes down, directly to the blade

those are not that suitable to build on a go-cart

you need a perpendicular transmission then

that's not good

an other advantage of this engine

it has a centrifugal clutch

that means that this part

doesn't turn when the engine idles

it starts turning when you accelerate

so we don't need to build an extra clutch

so you just push the pedal and off you go

ideal!

and do you know what's the best part of this engine?

it runs!

let's see where to put it

it's good like this

not bad

this is nice

it turns that way

so the rotational direction is good

it should go forward

we know where to put the engine

we can't attach that to those wheels directly

the engine doesn't have enough torque

therefore we need a transmission

let's calculate that

I will measure the wheel diameter first

let me see

it's 40cm

here's the engine

It's a Honda GX160

let's calculate that and order some parts

Before we start calculating I search for engine specs

I have them here

It does 3600rpm

we take that for the calculation

I've finished the calculation

We want to know the rpm of the outgoing shaft

we want to go 30km/h

wheel diameter is 40cm

that's 0,4 meters

I want to know the circumference

0,4 x pi

circumference is 1,256 meters

if we want to calculate the rpm

we have 30km/h

is 0,5km per minute

is 500 meter per minute

If we divide that 500 by the 1,256 of the wheel

that wheel should do 398 turns per minute

to go 30km/h

The ingoing shaft makes 3600 rpm

we saw that in the specs

We can calculate the gear ratio now

with this formula

i = n1 / n2

n1 is rpm 1, that's the rpm of the engine

3600

divide by 398

the gear ratio is 1 : 9,04

okay.. but then..

Overhere we have the entire happy oasis all together

here's the engine with exhaust with smoke coming out

here we have 3600 rpm

first chain transmission

intermediate shaft

another chain

and here's the wheel

and the wheel should do 398 rpm

the motor pinion was there already, it has 12 teeth

I thought to take a gear with 40 teeth

because I like that

the gear ratio overthere is

i = z1 / z2

that's the number of teeth

the amount of teeth of the big gearwheel is 40

divide by the teeth of the small gear, which is 12

we get a ratio of 1 : 3,33

Now we have to find out what this ratio should be

therefore we will divide 9,04 by 3,33

That makes 2,71

this gear ratio is 1 : 2,71

I want to use a gear with 14 teeth overthere

we have to calculate this gearwheel

formula is i = z1/z2

the ratio is 2,71

the big unknown is divided by 14 (not the otherway around)

we multiply that 2,71 by 14

we get 37,94

so we need a gearwheel with 37,94 teeth

but that doesn't excist..

so let's take 38 teeth

right.. enough talking

let's order parts, where shall I do that?

I think by INDI

Let me see! Drive technology

chain drives

chain wheels

sheet metal gears

simplex, single chain

1/2" x 5/ 16"

look at that! 8 teeth!

we don't need that

14 teeth, that one

38 teeth

and 40

I've added some chains and bearing

order it and proceed building!

Exciting!

That's nice! Cutting oil for the saw

closing links for the chain

now that's an odd gearwheel

gearwheels!

bearings

Oh no! This will never work anymore

Diesel is getting neurotic too!

Well.. let's build something else then

this one is broken

it's not that bad

we weld it back together, okay?

are you happy now?

Ideal, now we can slide the engine

because of those slotted holes we just made

that way we can tension the chain

That works! A sharp blade

that works better

Ow Dirk, what have you done?

the steering wheel is gone

how do we steer now?

Not, we're going straight only

Oh yeah, that's true

That's better then that flimsy plastic part what used to be there

I think that too

now you can hang on to it

We're looking at this for a moment..

it doesn't fit..

we have an issue.. take a seat

We don't have cranks, but we need to make pedals

and these pedals have to come where our steering mechanism is

see; this one

and this rod in particular

those are in the way for the pedals

that's not handy

I think we have to change that

we have a few options

we can cut the entire cart in half

there

extend it

the pedals could go there

but we don't like that

so we thought the next thing

we cut these

that as well

we can move the complete mechanism below the frame

and then we have enough space for the pedals

excellent I guess

I think so too

welding cutting..

hatseflats, let's make it

it's a shame, it worked so nice

hey, it works

ideal.. and look;

room for the pedals

steering rods mounted below

brake pedal

Let's make a kill switch

for safety

that's for pussy's

he wants to go for a ride

I think it's a good thing you think about safety

there comes the kill switch

can't miss it

we took a small, not too obvious button..

a surface-mounted light switch

and overhere

that the ignition breaker wire

if you connect it with ground it will stall the engine

we'll attach it to that switch

wire to ground

if you activate the switch, it will stall

we have a on off swich overhere as well

it's hard to reach

we wanted to have one close to the steering wheel

what a luxury

and then...

is it finished!

let's test it!

nice! I wanted to have go-cart like this when I was a kid

without cranks

with engine

awesome

it's ready for testing!

it works!

Let's see how fast it goes

37km/h

Not very comfortable

I can say this is a success

not very comfortable, but we didn't build it therefore

take a closer look

engine

transmission

intermediate shaft, to the rear axle

we have a accelerator overhere

cable through a steel pipe, runs to the back

to the engine

and for braking

we've used the original brakes of the go-cart

two blocks which can be pressed agaist the tires

overhere the original handbrake

we reinstalled it

but a foot pedal is also handy

it pulls with a rod

to the lever

which is welded to the rod that rotates the blocks

very simple, but it works well

do you want to have such a go-cart?

you've seen in this video how to build it

all parts come from INDI

I would say; good luck building!

If you have an idea what I should build

so you can see how to do it

I would say; post it in the comments

and who knows; maybe next time!

Hey folks, thanks for watching!

see you next time!
