Before you take the plunge, carefully consider the possible  
consequences of lubricating rudder cables with PTFE powder. I obtained  
some teflon directly from Dupont and at the suggestion of one of their  
chemical engineers, I thoroughly cleaned my cables with MCL. Then made  
a slurry of teflon powder and isopropol alcohol, coated the cables and  
let them dry. When inserted into the nylaflow tubing, they and the  
rudder moved with almost no resistance and I was very proud of my  
ingenuity.
Fast forward, (I'd be embarrassed to say how long) to final rudder  
pedal installation. The cables would only move with substantial force,  
they almost seemed frozen in place. With great difficulty, I managed  
to pull them out of the nylaflow tubing and they looked as though they  
were caked in dried cow dung. To make matters even worse, all four  
nylaflow tubes had this crud over their entire length.
To make a long story short, the cables and tubes are clean and work  
just fine, buyer beware...
