Nice link that one Paul

Be interesting what it goes for , anyone here going to have a punt at it ?? if not I'll give it a go ( not sure what I'd use it for mind you ) I wont go for it if others are going to have a go, no point in us bidding against each other is there

oohhh bless thank's for thinking of me Paul it is just the job it's a bit far south for me and im not too sure were my pass port is at the mo

I may use this as my plan B, as i have spoken to the head cases at z cars and I'm going to see them tomorrow, it's about an hour or so from me plus can visit family and go paddling on the beach.

I'm taking my wait so i mean business

sorry meant wallet.

Ayleybury is not that far from me and just the transmission wouldn't be too bad to post. You can get a pallet delivered almost anywhere in the country for £45. I had 3/4 Ton of diesel gen-set arrive that way.

Forget the overpriced Z-cars approach (except for inspiration). Do it the old fashioned way. Take your existing mini diff and change the bearings for sealed (2RSR suffix) ones. Clamp these in a couple of mounting blocks. Wind a strip of steel around the spider gear casing to act as a weather shield and coat the gears with 'open gear' lubricant. Bolt a toothed pulley or chain sprocket in place of the crown gear.

This is the way they were doing bike pwered hillclimb cars 20-30 years ago, long before the latest craze for fitting Hyabusa engines into everything.

The microcar transmission will get you a mechanical reverse, which is much cheaper than if you have to buy a reversing contactor set.

I'm back i know you all really missed me well i went to the coast and met the very nice but insane people at zcar's looked at some of there stuff and had a nice chat with them THERE BUILDING A BAT MOBILE the one with the jet in't middle so cool.

any way didn't buy any thing from them thanks for the advice Paul you probably wont believe me but i did consider something like you are suggesting but bottled out.

but..... i have found this http://www.westgarage.co.uk/forsale/kits/kit1.html

i didn't pay full whack as there are some marks on the oil can.

I HAVE BOUGHT IT NOW SO YOU CAN TALK ME OUT OF IT. I'm hoping to receive it late this early next week

contact is Douglas Anderson very nice chap

I should hope you didn't pay full price!

I guess I'm spoilt by having my own machining facilities, but I'd not pay anything like that.

What motor were you thinking of using?

[Teslas fag packet]

Well i have a lathe and vert mill, still it's bought me some time, it's a 72V series wound 10" job GE i dont know much about it and it was always intended as a start, get the car running and go from there.

P.S. have some 72V DPDT contractors from a fork lift

[EVguru]

10" long or 10"dia?

Do you have any performance data?

[Teslas fag packet]

Sorry no data at all I'm relatively convinced that i will end up getting a new one at some point. 10"dia 14" long

That's a Monster!

The motor is probably a series wound type, which has a non-linear relationship between currrent and torque and hence a non linear relationship between voltage and rpm. In fact off load the motor will try and rev to infinity. If the voltage is low enough then friction and windage will hold the rpm down, but hit it with the full 72 volt and you could burst the armature.

You should be able to make it work, but it's going to take some experimentation to work out the gearing.
