it was not baby oil it was baby shampoo   i was wondering how the baby oil had escaped from the bedroom 
baby shampoo is widely used in the sign industry for applying frosted film to windows, perfectly legitimate to have that in my workshop

good point with the vitara box  the middle and front axle would always be connected  leading to wind up on hard surfaces
you could just put the vitara box into 2wd and only the rearmost axle would drive

Les just a thought if you google 6x6 Land Rover Perentie you'll find some videos showing how Land Rover gets the drive to both axels. Just a thought.
and this guy
gives a good idea of how you could set up the springs.

i will have a read of those lets see whats what 

i had the idea of 2 sj/jimny  transfer boxes side by side  chain drive from the input of the original one to the input of the secondry one so they always work as a pair in unison, that way you can have the first box in 2wd high and  the secondry box in neutral  that way only the middle axle would drive,  first box in 4wd and the front and middle axle drive, add in the second box and the rearmost axle comes ito play,  the front output could run to power a small capstan winch on the front bumper which would be easy to make out off a diff

does that work ??

Lots of shiny bits. It's so much nicer working on parts that are properly clean.

As far as the transfer box idea is concerned, I can't see why it would not work. However as you are playing around with chains it may be easier to simply double up the output of one transfer case using a couple of sprockets and some chain. You wouldn't be able to independently select each rear axle but I don't really see that being particularly useful.

yes good thinking why carry a second transferbox around when i dont have too,  the bit i dont like about this method  is having to grind off the spring perches/shock mounts etc   so i can flip the rearmost axle upside down awful job that lol,

the drive through diff seems the least work ?,    i have a couple of sj axles kicking around  the place  maybe as a side project i will try and make a drive through axle  just to see if it works

so im not sure if i am going to use this metro engine or not,   i chose it because it was light and it was free,  being free isent really the best criteria for choosing it but hey ho

now what im after is a very low bonnet line to enable me to have the shape buggy that is floating around in my head

ive reduced the bonnet line by a fair amount but i would like more if possible.  on a standard jimny it seems to measure 19" from the top of the shock absorber to the base of the windscreen,

    moving my engine back and down has reduced that to 9"

File Attachment:


10 "  is great  but now im wondering if i should go back to one of my earlier ideas and use a subaru engine, hopefully its much lower being a flat 4
what i need is a scrap engine to offer up and see how it fits,   if the down pipes fit between the chassis then it might be worth it  if not i dont think i will be any better off,  they do sound cool though due to their unequal length headers  and i could probaly exaggerate that by making some more unequal headers lol,  if i were to use a forrester engine it has a hi/low gearbox before i feed it into the transferbox  giving me the low gearing i desire

The sight line with the Metro engine looks pretty good to me. I don't know how much you'd gain with a Subaru engine. The wheel arches are likely to be a limiting factor. You also need to be able to squeeze a radiator in there somewhere. You could put the rad in the back. You need to be pretty careful about air flow if you go that route. It also helps to over size the rad. Both my trials car and the Copelander have rear rads.

I personally find being able to see where the front wheels are is more important than being able to see very close directly in front.
