Rudder Trailing Edge

29th July 2009

After a lot of work tweaking things i finally got the trailing edges of the rudder skins to nest acceptably into the countersinks on the trailing edge wedge.

I mixed up some pro-seal and glued it in place. The whole assemble was cleco’d to a piece of pre-drilled aluminium angle to keep it straight while the pro-seal set. I also put a blob (technical term) of pro-seal between the left and right stiffeners where they meet at the trailing edge. This should support things and help resist the skin cracking in that area - a fairly common problem.

The pieces of fillament tape are holding the trailing edge closed between some of the clecos where there was some slight bulging.

Well you may have noticed progress has slowed lately…..After nine months of careful construction, Emily Rose Pengelly has emerged from the hangar and is the latest addition to the build crew.

Rudder Assembly part 2

06th July 2009

Attached the rudder skins to the skeleton. There are a few rivets that I can’t get easily. I’ll think about the various options for setting them and come back to them later.

Skins attached except for the double-flush rivets on the trailing edge

The last few rivets of the ribs of the rudder are tricky to set. I should be able to get all but the last one with my thin no-hole yoke. Then I will probably just use a blind (pop) rivet for the last one)

I cant get these four either. The palns say you can use blind rivets here also but i am going to wait and try my longeron yoke which I have ordered.

Rudder Assembly part 1

03rd July 2009

Started to assembly the rudder today.  Attached the nutplates and reinforcement plates to the rudder spar.

And riveted the rudder horn to the spar.

I couldn't get these two rivets with the squeezer so I bucked them.

 The tip rib was attached and the counterbalance skin fitted. I had to remove a small amount of lead to allow the rudder counterbalance weight to clear the rivet shop heads.

Counterbalance weight installed.
