Gwyn,
Back a few years ago I built some yokes and an interconnected yoke column system for my then B737 project and after trying both cable and bike chain, I gave up because I had too much flex in my columns and I couldnt keep the yokes synch'ed up with each other. In retrospec, I see that there are much better ways to build these than with the method I did.
I will soon modify my CH yoke and buy another one to mount on some new columns that will be a steel interior skeleton/cross over and have the pvc only for looks. On your site you mention the following:
"THE SMALL PULLEYS ON THE BACK OF THE YOKES ARE EACH FIXED TO THE WIRE ROPE." at http://aerosimsolutions.googlepages.com/22-Rollpitch--yaw-linked.jpg/22-Rollpitch--yaw-linked-full.jpg
What do you mean exactly by being 'fixed' to the wire rope? Do you mean that the cable/wire rope is somehow looped thru a 'yoke' of sorts mounted on the shaft of the control yoke, or that it simply rides over the top of the pulley and is a continuous loop of wire?
Also, is it possible to take a picture of how the wire comes across the top of the pulley where the yoke shaft meets the top of the column?
The system I built sound exactly like yours in the way the cable is ran (I think) but I used PVC alone for both the column, crossover bar, and had no bearings in the entire system, causing waay too much friction. Ive learned that lesson.
Thanks for your help and response!
