| Subject: | Re: Edge Distance At Ends Of Rib Flanges |
If it bugs you, you can assume the rivet does not exist (install it anyway), and
place another (min distance 3d but not > than1/2 the pitch). This is called
out in the construction standards.
I ran into a few of these situations and my personal handling of matters of these
is.... Add another rivet if only for your own piece of mind. Heintz says....
When it comes to areas in question default too less pitch, larger rivets,
thicker sheet etc.... In my humble opinion it is OK to be conservative.

Bill,
The MEK was used only to remove the grease from fingerprints and
handling. The Prekote and Scotchbrite were what I felt did the trick.
The fuselage was painted about 2 years ago and the wings about 1 year
ago.
I used 2 part NAPA automotive paint. Still looks great.

In other words, you weren't able to remove the corrosion, just prep for
painting.

Too late for me now, but I think this belongs in the archives if it

Ben-
Will do.The interesting thing is, the finished wings are still in
the same basement with no corrosion- they're visible in the pictures I
posted. The only problem I've ever had was with the stuff that came with
the kit. Can the paper make that much of a difference?

Howdy Bill,
Saw your posting on the Zenith list
http://forums.matronics.com/viewtopic.php?t=50611
I was wondering if you might have a piece of that corroded aluminum
left over. If you do, would you be willing to cut a piece of the
worst-looking stuff and send it to me? Something the size of a business
card or so would be plenty. If you send me some, I'll take it to work
and do some analysis that might tell you what caused the corrosion. I'd
be able to tell if it was biological, humidity, or caused by something
else. I'm a materials engineer and so I have access to all kinds of
analysis equipment at work. No guarantee I'll find a solid answer, but
my time and effort is free so all you have to loose is a piece of
corroded aluminum!
I'm storing some parts in my basement, some in the living room, and
some in the garage. I've been curious about corrosion during storage
and so you're problem could provide some good evidence.
Let me know.
Regards,
Ben Church

I was doing my own anodizing a couple years back (it's a pretty simple
process) and if you mess up you just dunked the part in a lye solution to
clean it off then started over. There's a drain cleaner called Red Devil and
is mostly lye, that you can probably still get at the grocery store. I'll
look up the actual chemical name and post it later (gotta find the book).
A couple interesting things about aluminum oxide (anodizing is an oxide
chrystal layer that looks like a microscopic honey comb which can be filled
with dye for color and when heated the cells close up sealing in the dye)for
those who don't know:1 it is very hard (aluminum oxide sandpaper will cut
steel) and corosion proof.2 it is non conductive.
