I came across an article by Rickey Horwitz describing different kinds of under seat steering and I like the looks of the Crossed Dual Link steering type.

Can anybody sees any obvious issues with trying to implement this on a Warrior.

Looking at the drawing and wondering if there is going to be any interference with your legs spinning the cranks? Dunno but in my mind it looks like it could happen...

I was wondering about that too, but I think the drawing is a little exaggerated. The tabs could be a little shorter.

Absolutely no leg fouling at all.

Thanks Savarin. That's it exactly. It not totally obvious how you attached the handle bars. Do you have any pics with the handle bars attached ?

My LoGo trike is done that way and no problems at all.
I asked how to set up the Ackerman. Usually you can run a string line to the centre of the rear axle to get a line for the tabs.

I was told to basically do just that then swap left for right. Of course you need to think about how the wheel attachments face too.

The centre pivot is a short length of tube that the cups from a wheel bearing sit in.
The bolt is a shortened wheel axle bolt so the cones can be used. It bolts through a tube thats welded through the frame.
I had to hunt for some tube large enough for the handlebars to slip into.
The clamp bolts were welded up first then the tube slit.
A hole was drilled at the end of the slit to prevent it spreading or cracking further.
(Thanks to John Lewis for this system)

If you mean how did I set up the ackerman....... I used Peter Elands spreadsheet and played till it worked out.

Thanks again Savarin. The pics & spreadsheet will be a great help. You did a beautiful job on your trike too. Hope mine turns out that well

one more thing, dont weld the tabs to the steering tube in the same plane else the tie rods will bind on each other where they cross.
I didnt do that and if you notice one rod is on the top of the tab whilst the other is on the bottom of the tab. I still had to make a couple of small spacers to get sufficient clearance when on full lock.

Don't mean to be stupid (just am) but what are the advantages of that kind of steering over others?

I wouldnt have a clue but the green trike steers beautifully.

Cross steering usually simplifies the system. One pushes, one pulls. It doesn't impove handling at all, just for someone who doesn't want independant steering arms. Take something like a truck, say you're building a truck or something with dual steering axles(Road cranes, Neoplan Megaliner) instead of trying to run an over boosted steering system and a setup for each axle, you can run a steering arm from say the right front axle wheel to the left second axle wheel. If anything it better equalizes the system.

YOu could even throw in a set of springs to help the return to center.
