Trial fitting rudder spar caps and hinge brackets


Trial fitting the rudder control horn



Fitting the rudder spar to the vertical stabilizer to check hardware and clearance, send ing question to Vans re the gap seen below, the plans allow for only one washer between the brackets. I don't think their should be a gap otherwise it will pinch when tightened, may be by design but it does not look right to me. (Note the spar holes and the brackets were pre-drilled and are self aligning)

Priming for assembly

Riveting in the K1000-3 Nutplates that will hold the Rudder brackets and bearings. I made the first of many mistakes and in my excitement and anxiety of setting my first flush rivets I squeezed the first rivet without the nut plate, chalk it up to needing practice drilling out rivets.




Flutes and deburred all the Rudder frame ribs, they are ready for priming metal to metal contact areas.
