And should you choose to put the tips on before fitting the elevators like I did, this is where to start:

Rigging manual part 1 which covers everything related to the elevator is nearing completion. I am on the road currently, but will be hopefully finishing it up in the hotel. With any luck, I should finish this week.

As Tony mentioned, the horizontal stabilizer is removed, flipped upside down and a long straight edge is placed across both elevators to assure alignment. Then a spacer is clamped between the arms and the hole is drilled into the other arm. We did not drill any temporary holes in the arms.

It is also recommended to leave all the fiberglass tips off until nearing completion. Part of the reason is to save damage, but the main reason is the only way to find the neutral position of any surface is the aligning the tooling holes that is on the end ribs.

Using the fiberglass tips as the neutral point is not a guarantee they will be centered properly.

Tony,
I think I understand now. You drilled the #40 hole in the Joiner control arms just to hold the alignment. You then took the elevators off the horizontal stabilizer, so you could drill the hole between the Joiner control arms (where the push rod will attach).

Tony,
If no permanent fastner is attached to the drilled #40 holes, then why are they drilled?

Glen

Glen,

There's no permanent fastener that goes where the #40 drill goes thru both shafts. The elevators are joined only by the rod end that ties them together at the bottom end of the horns. Photo of left elevator only with rod end and pushrod here: https://picasaweb.google.com/tonyboytoo ... 9693818482 Note that one horn is provided without a hole for rod end. Drilling the second hole in the horn is your only chance to be sure elevators (not horns) are aligned with each other: https://picasaweb.google.com/tonyboytoo ... 3610130386 Best to keep asking questions until you're clear as to what and why.

Tony

Thanks Tony. I'm good up to photo #285, that's where I'd like some clarification. There doesn't appear to be much metal to drill into on the female arm. Does it get riveted on both ends or is there a through bolt (doesn't look like enough room for a bolt)? Is there a target location to drill through (it looks like you drilled top to bottom with the elevators in the neutral location)?

Glen

Glen,

While you're waiting on the real answer, have a look at this:

Scan thru the next 8 photos to see how I did it.

As I'm working on the horizontal stabilizer, I'd like to attach the elevator halves to their joiner control arms. I figure it would be easier to do this now, rather than after mounting the fiberglass tips. The tail section manual tells how to attach the joiner control arms to the ribs, but now how to mount the joiner control arms together.
