SKID, doesnt fireman have a hydro locker from a big company? are the road usable?


nup, he got the last one ever made by the original inventor


and I think tpft is right, when he states that if you want one you do it yourself or pay howie

as for the road part, I'd seriously doubt if you'd get it certified

waltons truck jumps in the air every time he touches the throttle or hits a bump, i know he,s running airbags
but on more then one occasion it seems to be a benfit rather then hinderance.
same with bike trials, rider loading and unloading suspension


Do you know about squat and antisquat?
Basically it's how much vertical load your suspension creates under acceleration and braking. The right amount keeps the vehicle level and helps traction, the wrong amount makes your vehicle hop and loses traction.

um holy sheet, i was thinking of just joining it all together with a bit of pipe, having the cvs run open, they right though, if u got cv,s u may as well run rear steer..............

yeah i know, what i would term it as having is the " wrong amount" .
compared to the truck running inboard springs, whoose suspension performance is prob best i,ve seen.
it seems to benfit it on more the one occasion, as long as momentum is forward losing contact with terra fimra
can be advantageous .....some times

Just my guess but cool__bananas you need to think on two wheels not for . My first thought from the post was to 1300cc v4 bike engines but maybe 2 inline 4 bike engines :)

Have often considered a bent cv diff , it starts to get large when you consider you would have to be able to pull the cv's out and replace them etc . Something I will consider for the future when weight is not a problem .

hayabusa?
u mean one of thease things.........? cannot confirm or deny, but hey start a rumour that some nutter is building a truck
with 2x busa motors, nothing else get people thinking.

or u could take a ex-rail alky breathing 327 and put it in a bike, and take a bike motor and put it in a car :roll:
or better still 2x morris marina 1300 land crab engines :wink:

Image

10k though? hey i want to build my whole truck for like 10k, which reminds me rumours of guys spending 70-100k on new trucks?
how do u spend 100k on a truck with a pipe frame, 2 seats a 2nd hand engine from a wreck.
i mean c,mon no windows, air con, sounds, not even much paint.....................
(no offence um, whoever)

p.s anyone know how this viscous lsd diff works?
http://www.trademe.co.nz/Trade-Me-Motor ... 262585.htm

100k i,d spend 25 on a new shed and the rest to fill it.
maybe someone should start a post on how much their trucks worth?

it can cost that much if you get a kick arse engine, pay someone else to make it, make carbon fibre body panels, use a tricky as suspension set up etc it sll adds up pretty quick if you buy stuff with no budget :D

i was thinking about getting a couple of thoose mountain bike speedo units, the little electronic ones, and mounting a sender unit on each hub and the display above each fiddle, so navi can use fiddles to try and keep both front wheels driving
when he needs too, i.e drag the fiddle on the wheel thats turning fastest........................

he sticks hius head out and keeps a eye on his side wheel at moment but cant really tell if rh side is spinning or not.

yeah i prob think too much, suppose thats been done too?

dont think its been done but i couldnt ever imagine looking at some tiny as digital screen and trying to read number when your going full noise wheel standing up a hill of about to roll, but its worth a try. you could always use good old lockers :D

Get some abs sensors and use those. Bike speedos work on one magnet which swipes each revolution. They get lumpy at low speeds and many don't read below about 5km/h.

speed is unimportant, just would show the differance.
i think if u mounted them on hub, or even drill a hole threw axle tube and mount magnet on axle,
they would turn a lot more often then rim on bicycle..........
within 5kph may be ok

But kiwi bacon, what sort of circuit would it need to light a bulb on whatever axle is not spinning??

and cool-bannas, dude that your promblem, co driver is grabbing fiddles when front end is in the air. 8)
up hills having locked front diff sucks..

I would go with the idea of abs sensors and and some sort of balance circuit with lights on the top of the handles , handle lights up on the spinning side , the more inbalance ( ie one wheel spinning more that the other ) the brighter the light . Then he just has to pull on the handle with the light on . Gee even I could almost manage that :) .

My plan (yes I've thought about this a lot, but done absolutely nothing) was to run some frequency to voltage converters from the abs sensors (or even encoders run off the outside of a brake rotor to get as many pulses per rev as sensible), then the varying voltage can be used to drive some indicator lights (brighter light = wheel spinning faster) or some volt gauges.
My plan was to run a comparator to check the voltage between the two wheels on each axle, have a preset speed difference which would turn on a light or pulse the brake on the faster wheel (would involve electric/hydraulic actuators and a seperate braking system).

what about a neon sign " pull the other lever u idiot" cause most navi,s are not too bright........................

all sounds complicated to me, push bike speedo,s cost bugger all

how dare you

without the trusty navi....................

you drivers would be shite

and you know it


did you expect not to get a bite :shock: :shock:




now on the locking diff thingy, I will get my spy to do some research for you this weekend at the next extreme round. 8) 8) 8) 8) 8)

bent axles, Unimog axles, IFS, there aint nutthin new.........

iN THE SEARCH FOR GROUND CLEARANCE, this wee beastie would fill the bill.
Not too tall, like some around, Good visibility, excellent manouverability, turn on it's centre of mass, easy as.
Deepish water not a problem
go right over biggish rocks too!!
easy to work on, all the drive train is on top!!!

just strip out all the extraneous gear.

top speed, like 2.5 kph??
yeah, thought of something like that too, hard to get drive to a pivoting wheel
but mounting complete front and rear assemblys on some sort of central pivoting point with hydro steering etc may work

with extensive sceintific reserch (watching dvd,s) prob the biggest issue with getting a 0 is staying in the course.
my zuk with locked rear end, is alway failing to make a tight turn and fiddles only help a little.

I was underneath it yesterday, changing all the bent parts after last play, and if u ran a big cv in end of driveshaft. and mounted all suspensin points etc onto a indepndtant sub chassis, then would work..........

i love this sport, far more freedom then anything else i,ve done to go really...........mental

No, when I lived in AKL, in Mt Eden, NEXT to (NOT in) the Jail.... Henderson and Pollard's timber merchants, had a bunch of these straddles, they were good for maybe 20mph, say 30K?....

they ARE already 4wd, so THAT part is sussed, most had flat-head v8 motors, driving through torque converters, changing tht set-up would be easy. Straddles, even these small ones re BIG fukkers, though, you could drive VX Toymoda through the gap!! Ground clearance is not a problem, I feel thaaaat may be a tad top heavy.
