Setting up ik leg, problems...

Hey all, im not well versed in XSI yet but loving it, just having this one problem be in my way.

Im currently making a robot project (yeah we all start somewere) and im stuck on the rigging of the legs, so far ive tried using 3 bones to do the job but it just doesnt work right. heres some pictures..




I hope this explains my idea clear enough?

My main problem is I want to lock off bone 3 to just rotate on z-axis and have the other two bones (1,2) translate x,y to reach my foot null. At the minute no matter what I try (including upvectors) all 3 bones will bank/roll to reach the foot null.

Effectively im trying to copy the rear end of a JCB tractor exactly motion wise.

Any Ideas?
