I'm splicing up a set of cables for NC22211, a '39 BL-65, and was wondering if there are factory specs for cable lengths. We have some original cables to go by, and some replacements (nicropressed), and one always wonders how accurate the replacements are. I've found a couple of threads, like http://vb.taylorcraft.org/showthread...dder+cables%22 , but decided to start a new thread to ask again.
The cable lengths I have, measured from existing cables (measurements are from thimble bearing point to thimble bearing point, or for the cables with bushings, from the bushing c/l):
Rudder
Original cable, not labelled L or R: 200.0" (there's a second replacement cable labelled R, but cut, so this one could be either)
Replacement cable, labelled L 198.75"
(The thread above says 196" for the L and 199" for the R)
Shouldn't the rudder cables be the same length? And I found a thread that said that the rudder cables should have steel extension tabs like the elevator cables, is that correct?
Elevator
The elevator cables look to be good originals
Up elevator 188.0"
Down elevator 185.25"
Aileron
L front, original 139.875"
R F&R, replacement 143.375"
Since the aileron cables go to the center of the A/C, should they all be the same length?
The other three aileron system cables, chain connector and chain to aft cabin, look like good originals, lengths are:
Chain interconnect 32"
Chain to aft cabin 96"
Also, the modern turnbuckles are 1/2" longer than the factory originals, so new cables will need to be 1/2" shorter.
Comments or suggestions?
