Elevator work continued...

Well, we had another good productive day working on the RV 9 Elevators. Last work session left the Right Elevator ready for riveting to the spar and Ribs. We ended up using a small Tungsten bar and that really did a great job. Tad has a pretty good eye for using those bucking bars now so I continued doing the Rivet gun side. It really wasn't as bad as we were anticipating it to be. Just took our time and within an hour it was done. Even manged to buck the "problem rivet" on the counter-weight skin without too much problem.
So, it is ready for inspection now and we started on the Left Elevator. Match drilled the shaped stiffeners and then deburred most of the pieces. The stiffeners are dimpled as well. We'll probably get the spar and everything else matched drilled and then send them off to Tad's workshop to have them primed.
This Elevator has the Trim-tab on it though so it will involve a little more work to finish.

Continue Right Elevator

We've had 2 good work days only in the last little while but have most of the right elevator ready to be riveted to the spar.
Yesterday we did all the rivets for the spar, skin stiffeners, nut-plates,etc. The out-board rib to spar rivets gave us some grief. They just wouldn't set straight. So we fussed with that for over an hour i think. So basically we have the Skeleton together and is ready for the skin. We decided to stop there and tackle riveting the skin on a fresh day. We've read and heard it can be tricky to do... or maybe just time consuming as it will be tough to get in there to buck the rivets. We'll see.
Of course in Canada we have pre-close inspections so we'll go as far as possible but all trailing edges will be left open. I hope by mid-may we'll be ready for those inspections and then we'll be over one hurdle.
