| Hey Conrad,...... Borgeson makes a sweet steering shaft turn knuckle. I would use the ones that attach to a D-Shaft where the shaft has a flat edge for the locking screws to tighten down on....The turn knuckles can be bought through Summit Racing. Another option is to use tractor PTO drive shafts like I did on the Rumbler you can buy from a farm supply shop or Tractor shop.....One last suggestion is to cut out some steering knuckles from existing steering shafts from U-Pull-It....then slide steel rods into them and weld them on........ OH one last suggestion you could buy a steering rack from a supplier in Hot VWs that can mount on your chassis and as you turn the steering wheel it is geared to move arms outward. That could be attached through a heim joint to a rotating shaft down the control arm of the mini Tumbler. It would turn like the real thing.......Hope that makes sense......I'll keep that starter for you if you want it.....Looking good......BWD

Shaggy...how the heck do you know these things? And Thank you 4Reals for the encouraging words - i wish I could do this 24/7. I should've known Dave was going to give me more than one suggestion....the man is full of great ideas...so Dave fix this damn economy already!
I'm going to look around the net as per all of your suggestions. Thanks again guys..I'm giving myself 2-3 weeks to get the parts I need for this.

| Ok Conrad i came up with a simple idea, basing it off of a go-cart/lawnmower steering system. First off here are the pictures, forgive the cruedness i whipped it up in 30 minutes, and the items that i added are painted red. 
You may notice a blank area between the shafts, there are suppose to be "heim" joints there, or ball joints, either or. I didnt draw these but here is a picture of them i found at www.gokartgalaxy.com 
You might be able to pick up these parts at your nearest Home Depot since they do sell lawmowers. Anyway its just a suggestion

 I love how you just "come up" with these things. I'm looking at my front arms in 3D...cool. Good thing i didn't see this at waork today...I would have got nothing done.

| This looks like it can work. It's hard for me to visualize mechanichs it seems because you just gave me what is known as the "Ah Ha" moment. Very simple mechanics while i was thinking more complex. I'm printing this out.

This will probably work on a go-cart. but the rods that run to the wheels need to be parallel to the arms, and the "pivot" point for the cross bars/steering shaft needs to be under the pivot point for the arms. The heim joints will probably take up the slack, but if the rods aren't aligned parallel and the pivot points don't line up, when the suspension goes up and down the difference between the pivot points will try to make the "tie" rods move forward and back. (looking at it as a parallelagram the end of the wheel arm and the end of the link arm at the wheel are at a fixed distance. pivot points need to be the same distance to work together)

| TTC has a good point, the closer you can get the steering pivot inline with the front forks pivot, the better. Another reason i suggested this is because this eleminates the need for a telescoping shaft, and U-joints because the ball joints will take the place of the u-joints, and the position of the two shafts attatching to the main shaft should eleminate the need for a telescoping shaft. But keep in mind i havent tested the mechanics of this, and i dont know how much the design of this steering will be effected by the suspension "it works in theory"

On your cart I like Shaggy's idea of putting the steering on the bottom. If you turned the 3 levers by the body 180deg that would put the pivots closer to the pivot of the control arms. And I would think you could get them pretty close on the actual build.

TTC, Shaggy, Chilebean....It's like all you guys were right there in the garage with me when I was mocking this up and stumbled across that issue...the pivot points. I wondered how the steering rods would react when I went over a bumb and the arms moved. I see now why the universals are used to compensate for the movement. I agree about the ball joints. I was looking at heim joints - even though they are stronger than ball joints, they don't have the same range of motion.
In about a week and a half ( hopefuly) I will be getting all the parts I need for this.
