Make sure the plastic is off the skin. I used a water soluble cutting
lubricant and it helped things slide into position. once things are dimpled
it goes back together pretty easy.

Paul,
I just recently clecoed my leading edge ribs. After a long while of
struggling and cussing, I finally figured out a "system" that helped me get
the ribs in place. Here is a link to the webpage I posted about it:
http://www.hooverandassociatesinc.com/aviation/RV-9A/wings/leadingEdgeRibSkinClecoing.htm
If the link above is on two lines, you will need to copy the entire link to
get it to work. Hope this helps!
Regards,
Mike

| Subject: | Flap Jackscrew Rotation |
--> RV9-List message posted by: "Albert Gardner" <spudnut@worldnet.att.net>
Not too long ago there was a thread about the rod-end bearing lock nut on
the flap screw jack loosening up and allowing the rod-end bearing to
unthread. This allowed the flaps to abruptly retract with a bang.
Disconcerting at the start of an approach, probably much more that that near
the ground. Looking at a friends RV-9A the other day shows that there is a
good solution for that. Vans sells a Flap Positioning System
http://www.vansaircraft.com/cgi-bin/catalog.cgi?ident=1075299887-210-429&browse=airframe&product=fps
part of which is a sliding rod held on the flap screwjack with collars. It
prevents rotation of the extendable portion of the jackscrew is the same way
that torque links prevent rotation of landing gear legs. Making or buying
this part it might be a worthwhile addition to the flap jackscrew.

That sure wasn't elegant (I had to reach quite a bit with the first few
clecos), but it worked! Many thanks!

DWG 33, Detal E shows a Safety Wire to prevent the Flap Jack Screw from
spinning and dropping the Rod End Bearing if the Lock Nut gets loose.
I am also using the FPS from Van's, but I don't think it is strong enough to
prevent the Flap Jack Screw from spinning. I have applied "locktite" in
additon to the Safety Wire.

I just went by the directions and made the line 3/8" but I had to push the
stringer to get even close. I never did get mine to line up and the stringer
was pushed as far a possible. Anything wrong with having it installed off
the 3/8" line?

Here is the actual reply from Gus...I think you are fine.
I ended up going with approx 5/16".
| I assume from what you say that a line 5/16-1/4 from the edge
| would work OK. If that is so, go ahead and drill there. Any closer
| than 3/16 to the edge and you will not have enough edge distance.
| As long as the skin looks smooth it is OK, the actual position of
| the J stringer is not critical.

Given a choice, I put the shop head against the thinner material. If I
have to drill it out, there is less chance of bending the metal when
pushing out the shank after breaking off the shop head.
