Hi rvators,
I have had a really tough time getting the HS skin clecoed to the
skeleton. I have read about the problems with the nose ribs and I did
encounter those as well (not before bending out the skin at the tip,
alas). But on top of that, both of my spars and several main ribs
seemed to be sitting up very high in comparison to the skin, as if the
skin was a little too small. A lot of pushing down on the skeleton
and removal of all the spar vinyl *just barely* got me close enough to
put clecos in (I hope) without damage. They were not perfectly lined
up by any means! Maybe 20% blocked or so in some places. I even had
to move around on the rivet lines looking for closer holes to bring
everything else into alignment.
I do not have a very warm fuzzy feeling about this. I know this is a
"stressed skin" structure but this seems a bit much.
I have read about sanding ribs in the archives, but in order to
reduce them such that the spars fit better, it would seem that it
would rapidly weaken the rib at the flange bend. I have also rechecked
the jig, skin alignment in the jig, and fluting on all ribs.
Any other advice? Or is the whole thing normally a tricky fit?
Thanks,
Paul

Make sure the ribs are straight. It is a tight fit
but I don't remember it being that tight. I would not
sand a rib either. Deburr, polish an edge, flute but
removing material would bother me in several ways, not
only are you removing material but the alcad surface.
Make sure the ribs are straight, really straight, I
have caught my self both under and over fluting.

Paul,
Did you remove the plastic on the inside of the skin?

No, the skins are still totally covered. Think that matters?
I guess I could see that moving the skins outward enough
to make things come up a little short at the top...
I always wondered about the sense of match-drilling with the
skin still on (here or anywhere else in the kit). The manual
says it's ok, but I don't quite believe it.
Or is it enough to match-drill with plastic on then just count on getting
a better fit once the plastic is all off for final assembly?
Paul

Hi Paul,
I think it will matter. I removed the plastic on the inside skins and a
narrow strip from over the rivet lines on the outside. A trick several builders
shared with me was to use a small soldering iron and a long striaght edge to
scribe a line along both sides of each rivet line. 5/8 to 3/4 inches wide. The
scored mark will then tear and you can pull off a strip of plastic coating
just where you need to match drill, deburr and dimple. Just take care that you
don't press down hard enough to score the aluminum as well. If you do you will
just have some rubbing to do.
Good Luck.

| Subject: | Rib to Spar Rivets--Thank You |
--> RV9-List message posted by: Warren W Hurd <warren@ahyup.com>
Many thanks to all those who have written about my rib to spar rivet
problem.
Things that will be changed when I try again are.
1, A 3X rebuilt rivet gun just ordered from The Yard
2, A long straight rivet set.
3, I will also try to find some hockey shin tape to put on the rivet
head.
4, Turn the spars upside down so that I will be looking at the factory
head during the riveting process.
5, Remove some the wooden spar supports so the spar will flex slightly
during riveting.
6, Try a starting pressure of about 40 psi.
7, Smooth out some of the smileys on the ribs. The spar was undamaged.
8, For some reason I had thought that the flow valve hat comes with a
gun kit was ball valve. So in the future I will turn it more than 180
degrees. I had thought the valve was rather ineffectual.
9, Make a small gauge to locate the center of the rivet, and remove the
bad rivet heads.
10, Then drive out the bad rivets with a punch.
I also liked the exhaust pipe anti rotate tool, which I will probably
try at some time.
Thanks for the many words of encouragement. My confidence has been
restored.
Warren

--> RV9-List message posted by: dralle@matronics.com (Matt Dralle)
******************************************************************************
RV9-List Usage Guidelines
******************************************************************************
The following details the official Usage Guidelines for the RV9-List.
You are encouraged to read it carefully, and to abide by the rules therein.
Failure to use the RV9-List in the manner described below may result
in the removal of the subscribers from the List.
RV9-List Policy Statement
The purpose of the RV9-List is to provide a forum of discussion for
things related to this particular discussion group. The List's goals
are to serve as an information resource to its members; to deliver
high-quality content; to provide moral support; to foster camaraderie
among its members; and to support safe operation. Reaching these goals
requires the participation and cooperation of each and every member of
the List. To this end, the following guidelines have been established:
- Please keep all posts related to the List at some level. Do not submit
posts concerning computer viruses, urban legends, random humor, long
lost buddies' phone numbers, etc. etc.
- THINK carefully before you write. Ask yourself if your post will be
relevant to everyone. If you have to wonder about that, DON'T send it.
- Remember that your post will be included for posterity in an archive
that is growing in size at an extraordinary rate. Try to be concise and
terse in your posts. Avoid overly wordy and lengthy posts and
responses.
- Keep your signature brief. Please include your name, email address,
aircraft type/tail number, and geographic location. A short line
about where you are in the building process is also nice. Avoid
bulky signatures with character graphics; they consume unnecessary
space in the archive.
- DON'T post requests to the List for information when that info is
easily obtainable from other widely available sources. Consult the
web page or FAQ first.
- If you want to respond to a post, DO keep the "Subject:" line of
your response the same as that of the original post. This makes it
easy to find threads in the archive.
- When responding, NEVER quote the *entire* original post in your
response. DO use lines from the original post to help "tune in" the
reader to the topic at hand, but be selective. The impact that
quoting the entire original post has on the size of the archive
can not be overstated!
- When the poster asks you to respond to him/her personally, DO NOT
then go ahead and reply to the List. Be aware that clicking the
"reply" button on your mail package does not necessarily send your
response to the original poster. You might have to actively address
your response with the original poster's email address.
- DO NOT use the List to respond to a post unless you have something
to add that is relevant and has a broad appeal. "Way to go!", "I
agree", and "Congratulations" are all responses that are better sent
to the original poster directly, rather than to the List at large.
- When responding to others' posts, avoid the feeling that you need to
comment on every last point in their posts, unless you can truly
contribute something valuable.
- Feel free to disagree with other viewpoints, BUT keep your tone
polite and respectful. Don't make snide comments, personally attack
other listers, or take the moral high ground on an obviously
controversial issue. This will only cause a pointless debate that
will hurt feelings, waste bandwidth and resolve nothing.
