Ive just spotted a inavalid car motor/trans the same as yours mark on ebay brand new 800W, im loathed to buy it now as im still 99% sure im going for larger wheels and that will mean i have no chance of changing the gearing if i need to.

BTW did you put your wheels directly onto the shafts.??

Very nice unit all the same.

Hi Jimmy,
No I didn't. I modified trailer hubs to accept a sprocket and Brake disc (from a mountain bike),

and a good friend of mine machined stub axles, which I welded into the ends of the Toylander axle



The original scooter hubs were machined slightly to accept another smaller cycle sprocket to reduce the gearing

which passes through the body tub into the wheel arch.

I have since been advised by other builders, of a website that specialises in hardware for robots. This is www.technobots.co.uk, and they can supply heavier chain and sprockets, more suited to our vehicles.
This will allow you to gear down for any increase in wheel diameter.

If you use a 4 wheel scooter for parts, besides the Lights, Horn, Indicators, Battery meter, Control Box, and Batteries, you will also have all the steering pivots and rose joints for the front axle. And, depending on the width of the tractor, you might be able to use the swinging axle from the scooter without modification.

Just a Thought,
Regards,
Mark.

Ahh i see now thanks, i couldnt see that part in the other photos.

Thanks.

Hi Jimmy,
I just remembered, when I mentioned using a Motobility Scooter for my build, Richard told me a friend of his used the same sort of setup without gearing it down. He said the car wouldn't pull away under its own power without a push, but would do in the region of 20 mph! Not suitable for kiddies!

I notice that Walter has explained gearing in one of the forums, it's just a matter of which gear sprockets are available from technobots.

I know that Engineering any specialist parts is not going to be a problem for you, so any mods should be well within your capabilities.

Keep thinking,
Regards,
Mark

Oh my word...i am never going to live up to the expectations, I've seen a lot of very fine work on here.

Hi Jimmy,
Now's your chance to put us all to shame then!!

Mark.

Hello Jbob.

Another good source of gearing parts, sprockets etc,  is a company called "Bearingboys", you'll find them with a Google.

Regards,

Brian.

Oooh very nice thanks.

Hiya, sorry for the delayed reply.....................

I use the same motor but directly with wheels, its geared quite well to my surprise, the car does 6mph on the flat, slows down on hills, not particularly fast. I must have had a lower geared motor, i estimated mine is geared 20:1, motor is about 2500rpm i belive.

Well ive started . . . . sort of.
Today i made the first cuts, I've cut out the floor and the sides for the motor/seat housing.
The first thing I'm slightly concerned about is that the 12mm wood looks awfully thin for such a big machine.

Ive posted a picture of the first basic panels stood together.(not finished
There is a lot more cutting and screwing to come.

I also need to tidy my work bench..

Hi JimmyB,
Don't worry! Yes, at the moment it will look flimsy, but remember, there are 1" x 1" battens to be Glued and Screwed in place, which add strength. The whole thing will be very strong when it's complete!

Just remember, Richard has had to design these vehicles, and have them pass a minimum 'CE' safety standard, before they are sold to the public as toys.

If you check the front of the build manual, you'll see the 'CE' mark, and the Safety Standard number printed on it.

The wood bits are easy, just wait 'til you have to sort the drive train and electrics!!  Enjoy your sanity while you can!

Keep Busy,
Regards,
Mark.

Don't worry about looking flimsy, the Toylander 2 bodyshell is immensely strong due to the box type construction. If my three grandchildren can ride in it together, it certainly aint flimsy!
And how can you say that workbench is untidy? It's better than mine after I've cleaned up! Seriously tho' I soon found it got too big, and heavy for the bench anyway, and I had to use the bench to work on , but leave the model on the floor. I've seen a few pics where people use two trestles or workmates, but you still need lots of space to get around it.
I'm sure you'll find a way forward.
Best wishes
Walter

Hi Guys,
Yep, space gets tight quick.
I solved this problem by fitting a set of small wheels from an old childs buggy (pram) to the bottom of my old workmate.
 
It doesn't look pretty, but at least I can wheel the thing out of the workshop onto the patio, if I need more elbow room!!

I agree with Walter, my workspace looks like a bomb's gone off, but if I tidy up  can't find anything!

Keep Busy,
Mark.

Ive sorted and indeed ordered all the parts for the drive train, I've junked the diff idea mainly because the postage cost from the USA is more than the item.!!!!
The drive is a bit overkill but i like it, twin motors driving through a two stage gearbox.
I cant wait until my parcel arrives from technobots.
