How do you secure kevlar on pull-pull?
I'm putting pull-pull on an older Morris knife that had pushrods. I bought 100lb kevlar cable.
I've used the coated metal cord that comes with Morris kits, but have never used kevlar.
What do I do? Tie it in a knot and ca it or do I use brass tubing like you do the coated metal cable?
Thanks for the help.

Re: How do you secure kevlar on pull-pull?
Tailheavy:
The aramid/Kevlar tends to break if it is bent sharply.
If you are using clevises on one end, run the cord through as you would insert a pushrod, then bring it back outside, wrap it around the clevis and tie it. Fill the clevis, where the cord goes through, with slow CA.
For the adjustment, use a hollow threaded end, or "Threaded coupler" like Du-Bro #111 or #695. Using one of those, push the cut end of the cord in (Be sure you measured it carefully) and again, medium CA.
Anything else, just avoid sharp bends as much as you can.
Note: Most aramid cords tend to stretch a little when put in service, so allow adjustment for it. Once it has done this first stretch, it wont stretch any more.
