RE: 40% 330l pull pull
Chris,
What you want to do is feed your pull wire through you ferrel then through you linkage ( we use a 4-40 ball link with an sullivan 4-40 eylet attached to the control horn) back through the ferrel.
Ok you want to make sure you have some extra wire because now you want to loop back over the ferrel and push the wire through the ferrel again from the linkage side all before you crimp. What that will do is lock the pull wire in so it can not slip.
To crimp it I would go to lowes or a fishing supply house and get an inexpensive crimping tool. Then you will be set forever!!
good Luck
Al
