| Subject: | Leading Edge Riveting |
I have yet another question for the groups..
I am trying to figure out how the leading edge ribs get riveted to the main
spar. I know the mechanics behind it but what I am trying to figure out is
how people have gotten their arms down that far to get to the center two
ribs and get the angle needed for a bucking bar in there?
Did you go out and rent an Orangutan with long arms to reach down there?
I got the two inboard ribs riveted to the spar and the two outboard ribs
riveted as well. Short of climbing on top of the spar or inside the leading
edge I am at a loss for the center ribs.
I know that Dan C. said that at one point Van's told him to use CS4 blind
rivets but I am not sure I want to go that route without talking to them
this week which I know wont happen until Tuesday.

The leading edge is built on the bench and so the only rivets you have to
drive to the main spar are the ones on the bottom (well, aft) flange. And on
the main spar, there's lightening holes. If you have a riveting partner,
it's fairly easy. On reaches in the outboard ribs lightening holes and
bucks, one shoots.
I built my wings with a jig, which holds it vertically, and there were no
bottom skins on. So really I don't think the arm length issue is at play. As
I recall, the problem is it's difficult to get a rivet set on the head of
the rivet because of the main ribs. You have to -- well, *I* had to, grind
down an offset rivet set to get it be be perpendicular to the rib.
Some folks use pop rivets for the middle ribs. I've done it both ways. I
think on one wing I pulled a couple of pop rivets on one wing. On the other
-- because I had a helper on that one -- I bucked and he shot.

Leading Edge RivetingScott,
FYI, CS4 blind rivets are for countersunk holes. In my case Van's OK'd
the use of LP4 rivets to fasten the leading edge rib flanges to the
spar.
With a ground-down double offset rivet set, flexible wrists, and good
feel/visualization skills, it can be done with solid rivets.

With a long set, you might get away without the offset. I had better
luck with that than with the offset.
