Just to stir up the corrosion pot again.



For what it's worth. I screwed some bare aluminum pieces (6061) to

the back fence about 6 years ago as a sanity check when building my

plane.



Through sun and dark, acid rain, sleet, hail, you name it. There's no

sign of any corrosion whatsoever ... I live in Chicago, so we do have 

bad weather.



The only corrosion on my Kitfox has been a tiny bit on the landing gear

plates, and the engine mount where some powder coat got chipped off.

Jeff, 



“Through sun and dark, acid rain, sleet, hail, you name it.... I live in Chicago, so we do have bad weather.”



 And then that stuff blows east across the big lake towards me and Lynn. 

Now we know who to blame....

Please excuse the intrusion of a metal basher on the list:) but Hey! this is a subject I know a bit about especially as my current project is practically all aluminum:)

    

   Basically, whether or not to do any corrosion proofing depends on where you live and fly. For the most part unless you operate near salt water just keeping things nice and clean will protect things very well.  Just a small amount of salt in the air can change that dramatically. When we built N24ZM we lived approx 15 miles from the ocean. and the airport it was based at was around 8 miles inland. Most of our flying was inland as well and we never had a corrosion issue. That changed when we moved up to MLB which is maybe 2 miles inland. We also   tended to fly low up and down the coast a lot. The result was that corrosion would creep in anywhere the paint was scratched, nicked, or where the metal was left unprotected. On the F1 everything gets etched, alodined, and primed with a fluid resistant epoxy primer prior to paint.

But more importantly Danny, did Skystar pay you guys for your comments

on the sales video 



I still get pissed every time my Kitfox doesn't go up at 2000 fpm, and I couldn't build my plane with just a hammer an pliers either

To cause  corrosion you need an electrolyte...  Salt water sounds pretty good to  me.  Fresh water is not an electrolyte and can even "wash" salt off a  plane.

  

 I know  one old bush pilot who used to regularly land his 4130 framed Super Cub in the  brine.  I asked him how come it didn't rust to bits.  He told me after  landing in salt water he would always fly through a few clouds (VFR??) on his  way to home base.  He said the fresh water of the cloud would wash the salt  from his plane.  Being a relatively new pilot I have decided not to plant  my 'Fox into any salt water but it is stored in a garage about 30' from the  North Atlantic, a considerable source of salt.

  

 Yes I love to fly low and slow at about 10' off the swells, keep an  eye out for the big one!  I always land in fresh water and not too often do  I fly in rough weather so my plane is about as salt free as can be expected in  this location.

  

 I do  have a bit of a question about the aluminium on the fence....  Is the steel  part of the fence rusted where it came in contact with the aluminium?  Also  remember aluminium forms a thin protective layer of oxide over itself in short  order.  Unless there is an abundance of electrolyte (salt) around I'm not  too surprised that it hasn't corroded to bits.

  

 One of  these days I'll have to try the funny round rubber things that came with the  plane or maybe the boards.     (skis)

Steve,

When I attempt to read your emails, a lot of the characters are gibberish.

Other members have also commented on it.  At first I was using Eudora as my

email client and I blamed that, but now I am using Outlook and still reading

your emails is a strain.  They are never boring and I do enjoy reading them.

Still may I suggest that you set your software to send "Plain Text" when

posting List email.  I believe that would fix the problem and remove an

annoyance to List readers.  Since you read your postings with the same

software you use to send, they display normally and you are totally unaware

of the problem for most, or all of the rest of us.



Thanks,



Jim Crowder

Hmmm hammer and pliers, Eh?   If the pliers were Vise Grips you could

probably build a Harley...but you would need a big hammer   Sorry Mssrs.

Jim,

  Sorry... I do realize that my post may show up somewhat "corrupted" when read through misc. e-mail clients.  All I can say is when viewed using the actual Kitfox List web site http://forums.matronics.com/viewforum.php?f=8&sid=83b6acbe5602af72d6c023eab4688518

all will be right and legible.

I sometimes compose using Microsoft works, then cut and paste to the List Message Body window, and this might be a cause of corrupted e-mail. It does not affect the List site viewing.



I post right to the site, and forget that others receive through e-mail. While I regret the e-mail corruption, it is not my intention to send e-mail to every viewer\reader. IMHO, the List site is the only way to go.

  Thanks for the input.

Steve

Emails like this coming from new guys makes me roll my eyes, especially

early in the morning before I finish my cup of coffee.  "actual Kitfox List

web site"?  "the List site is only way to go"?

First off Steve, I appreciate your input.  You seem like a fairly well

informed guy, but Jim is right.  You are having a configuration problem with

your mailer, or perhaps it's the method you use to copy/paste.  It isn't the

other 500 people here, but you're making it their problem.  Your emails are

the only ones coming as Jim Crowder described.  You've been told about it

before, but apparently ignored it.

Second, if there is an "actual Kitfox List web site" it would be

Sportflight.com.  Matronics is a mail server.

And third, your opinion about "the List site viewing is only way to go" is

noted, but what you don't seem to understand is that this list has been

around for close to 20 years, gone through several mail list servers, and

still has many of us old timers hanging on, as well as some charter members

who kind of like the email version of the list.  When we changed to Matt

Dralle's Matronics server about two years ago there was no forum at that

time, but was added about a year or so ago as an option.  What is happening

is that many new members are taking the forum option because they aren't

aware of the email option and we're getting a mix of forum and email,

probably in the neighborhood of 20/80.   One of the big problems with the

forum version is that for the 80 percent of us using the email version is

that we often don't know what the forum contributor is talking about because

he/she usually doesn't quote any part of the message they're responding to.

Not a huge problem, but definitely an annoyance.

Please check your configuration settings and set them to plain text so that

we don't have to sift through all the html codes.  A lot of us would

appreciate it.

All,

I bought a Model 5 that was ground looped and needed to be repaired. In 

doing so I removed everything from the frame to repair, only place I found 

rust / corrosion was on the cross members under the floor boards, the area 

had been stuffed with insulation and was retaining moisture. Might be worth 

removing the floor boards during annual inspections for those that have 

never pulled them.

My 2 cents worth.

Sounds like the previous owner wanted to fly a house.  



You said the area was, "stuffed".  I expect that means it was fibre glass

batt insulation.  That would be  the problem with retaining moisture, no air

could circulate with the batts there.
