flex cable question
Hi guys, I was just wondering if anyone has some advice regarding a flex cable setup I am building a 1200mm mono and am running a weed eater motor with square drive. I have purchased a stinger drive complete with a prop shaft, which also has a square drive. The cable I have has one square end and will need to be shortened. Does anyone have any ideas of how to create a square end on the cut side? I have also noticed that the when cut the 1/4 flex is too big to fit in the female square drive so I will have to squeeze it some how, Now here is the problem, I dint know if anyone has done this successfully but i trued to bash an extra piece with a hammer and its not easily done. Just wondering if anyone has any ideas. Is there some kind of collet that has a male square end?
All theories welcome as I am currently in the dark.
Thanx Damo...
