How to set up pull-pull cables

[Rcmaster199 at aol.com]

Eye Bolts are my preferred method. I stay away from the Dubro threaded  
couplers since the sharp edges of the attaching hole have ripped  through steel on 
one of my models.
 
I still have a quantity of K-Kord, teflon coated braided kevlar for  sale.

The 4-40 brass connector Rick mentions works nicely and looks  slick.
If you don't have the special brass connector,  4-40 eye bolts  from Sullivan
will do nicely.
