<div> if money is an important variable, bungee cords, heavy duty springs, next step up door cylinders use two, they bottom out pretty easy, I believe the VW dampers would be next<br>

<pre style="font-size: 9pt;"><tt>Hi Roy<br>
How about a cam and follower, you can adjust the cam profile to <br>
provide increasing resistance to rotating the yoke. If you have <br>
access to SolidWorks Motion you can design and model the forces and <br>
make changes before the chips fly.<br>
<br>
Also you could use a servo motor, and a motion controller. There is <br>
some software that allows to design an "Electronic spring".<br>
<br>
Then there are the bungee cords and VW steering damper methods you mentioned.<br>
