Cables may not look bad at first sight. If you remove the cable and bend it where it went around the pulley, some threads may break from bending it the opposite way. Rubbing a piece of tissue on the cable will find broken threads. It rips off on the sharp ends. Watch your fingers the threads are sharp.

Is this true? I got stainless cable to replace mine. Maybe I should have gotten the Galvanized cable?

Ed / All,
In retrospect my statement about stainless cable being inadequate for
our Kolb aircraft applications appears to be an exaggerated
overstatement.
I have not been able to find the specific data to confirm my comment
and even if I had it would probably have been outdated by now anyway.
If your stainless cable is rated “aircraft cable” it is most likely
is more than adequate for our use. However that said, it is true
that “aircraft cable” is made in several different types designed to
meet various specific criteria.
I apologize to you / all, for making what appears to me now to be an
exaggerated stereotypical statement about stainless steel cable for
our Kolb planes.

Gene, As it happens, I was buying cable last night from that great aviation supplier, McMaster Carr (www.mcmaster.com ). The have an excellent set of drawings of cable types and a spec table for each type. Look under wire rope.
As for this worry about control cables beaking, consider this. Hang gliders use this same cable as primary structure. My 1981 Sensor 510 has stainless steel, 3/32" rigging. I inspect it every time I set it up and I end every flight with a wing over just because. Now that I live in Kansas, I'll have to give up the wing over unless it's a REALLY GOOD day.
