(...) Using feedback, it should be fairly easy. I once tried this with the current switches, and it sorta worked, but the "dead spot" is way too big, and those switches need so much force to move! It was harder to turn the steering to operate the (...) (23 years ago, 7-Jan-02, to lugnet.technic)

I do like that 'swivel hips' idea with the turntable, it would save me alot of unneccesary bother! I couldn't find a scan of the 8459 central steering design, so if someone could describe it in a little more detail I'd be very grateful Cheers Robin (...) (23 years ago, 7-Jan-02, to lugnet.technic)

(...) Admittedly I'm not too experienced with penumatics. But I think it would be hard to achieve the precision needed for fine control with plastic/rubber switches. And the quality control needed to fine tune every switch so that they behave (...) (23 years ago, 7-Jan-02, to lugnet.technic)

(...) Yeah, the main problem is the switches - if TLC would make a nice sliding pnuematic switch (similar to steam engine valve), pnuematic steering (and lots of other neat stuff) would become much easier. ROSCO (23 years ago, 7-Jan-02, to lugnet.technic)

(...) BTW, I think that it is probably fun to build a vehicle with pneumatically operated steering, and it looks cool. But for the precise control required by a steering system, I don't think the pneumatic cylinders are adequat. They are great for (...) (23 years ago, 7-Jan-02, to lugnet.technic)
