Eliminating The Rubbing

Wasted a lot of time today getting the elevators tweaked. I had rubbing issues on both which isn't uncommon. I tried hand massaging the leading edge profile with only limited success. Van's promptly answered my query about backing the rods ends out. It as an acceptable and common solution to elevator rubbing. I just need to ensure I have at least 1 thread protruding out the back of the nut plates they screw into. Fortunately with my recently purchased borescope I can, with some patience, view and photograph the back side of the nut plates to make sure that issue is good. I required two full 360 degree turns of the rod ends to fully eliminate the rubbing. This moved the rods ends out approximately 2 mm (.079"). Rubbing was more of an issues at the up and down limits of the elevators vs the neutral position. From the borescope views I've still got 1 thread protruding on the back side. I'm finally moving through this problem and can focus on drilling the control horns next. To that end I fabricated a wood block per plans to stabilize the control horns while drilling. This is another one of those "measure 50 times, drill once" type things.
