Thread: Making my own Land Rover from scratch

While this is an interesting project have you checked UK rules/law around this type of vehicle and insurance requirements?

Not an expert but you need to be very careful where and when this is used once up and running

I have gathered together a Kohlar 12hp motor and two three speed gearboxes plus the axles from a mobility scooter. Also got some 2x2 4 mm angle for the chassis.
The wheels are going to be 8 inch trailer rims pinched from a model trailer that I've scrapped

Wheels I'm using are going to denote the size of the 107 so starting from there, need to weld them to the little scooter rims so they fit the drive axle. I recon the Landy will be about seven foot six long

First problem I have is the drive train, I'm stuck with the 42 tooth sprocket on the diff because of the availability of larger ones to fit, might be able to bolt one to the one that is on there.

Engine is vertical shaft with pulley underneath, first gearbox I have is pulley underneath with 3 forward gears and reverse, out put is via a 9 tooth sprocket which is too small to weld or bolt a bigger one to it, also can't find a bigger splined one to fit
With a centrifugal clutch under the engine and the gearbox driving a 42 tooth diff on the eight inch rims (17 inch tall with tyres) I recon I'll get 10mph 0r less flat out on top which is no use,

I cant find any pulleys the right fitment to reduce the size of the plastic gearbox input pulley and can't change the small output sprocket on there so other things I can try are bolt bigger pulley under engine or try and sort a 60 tooth for rear diff

Another thing I can do is fit the second 3 speed gearbox in line to up the gearing, this will mean a two stick gear change, low, med and high plus three and reverse

So... small pulley on engine bigger (X2) on gear box input
Tiny sprocket on gearbox out put driving 42 tooth sprocket on diff
Not going to work is it

Only have a small budget so working with scrap, got an old classic Mini steering rack which I'll use long ways along the chassis operating the steering rods on the front axle, all I need now are brakes, looking like that'll be a disc brake and calliper on the back axle so not difficult.

Wish me luck, I'll be needing some body measurements though, only got length and width from landy drawings etc, they don't give such things as door size wing width, grill width and height etc etc

Budget is 1000 Aus dollars

Answer your question, Dave?
