Use the Nicopress 64-CGMP tool using the 'M' jaw

There is no adjustment on rudder cables on S-H gliders other than a few
twists allowed in the direction of the twist to effectively shorten it,
never the other way. So you have to make them up to as close to the correct
length as possible.

I removed the old ones on my Discus and laid them out on a long bench
covered in clean paper and measured at least 3 times and cut once! When you
pull out the old cables attach a cord as a pull through - just in case.

And I had a second pair of hands/eyes to make sure I didn't get it wrong!

The stress of doing it is much greater than the material cost but of course
if you get it wrong the only real damage will be to your wallet. Because
it's not expensive don't skimp on the cable and try and get exactly the
right length - it probably won't be!

If you Google 'Nicopress' there's plenty out there on the correct way to do
it.

Have fun
