Having read about how hard this is to do, I wasn't looking forward to this. As my old cables were long gone, and I had not pulled any string through I ended up fishing some tie wire through both holes. After carefully taping the new cable sheaths to the wires my wife I and managed to get them through the stab. That wasn't all that bad but we didn't know what was to come. The elevator required pulling both through at the same time as they are so stiff - one up and one down. This proved to be extremely difficult as one would be out and then back in as we got the other one out.
We finally ended up pulling them back into the stab and extended to the back as far as possible. This allowed more room to manouver the sheaths into the elevator. We finally succeeded and clamped them to the tie down strips. Then had to push them back into the stab while lining up the elevator hinges. By far the most difficult part of the build to date.
Now that one elevator was on, the other one was easy as there were no cables.
Then brought stab over to the plane and attempted to get it into position. Bolted up the bell-crank and attached the elevator cables. It actually dropped right in and then we found out that the listed bolts required were 1 size too short. Now have to order 2 AN4-40A bolts and that will hold up mounting the vertical stab and rudder. Time for the scars to heal.
