| Subject: | Re: stabilizer skin alignment |
I put in shims where the two outboard ribs attach to the spar.
I also found that the precut slots for front attachments needed to be ~3mm longer
before I could get the pre-drilled holes on BOTH sides of the stab to align
with the skeleton. Just check where the holes on the top side are going to be
before you drill the bottom!!
Matt also appeared to be having a similar issue with his pre-drilled skin and rib/spar alignment http://www.zodiacxl.com/1%20Horizontal%20Stab.html

Can someone tell me if the control cables are galvanized or stainless?
Zenith wants $71.00 for 100 feet, but I am finding it for under $30.00 for 250
feet for galvanized, so I am thinking I am missing something here. Does it
have the PVC coating on it? Any help or suggestions on this would be great.
I
want to get it ordered and start rigging!! Airplane noises are much cooler
if parts move!!!!!

Larry,
My cable, from ZAC, is galvanized.? When doing price comparisons, just be sure
you are comparing apples and apples.? "Aircraft cable" is not always really aircraft
grade cable.? Some venders call it that because it is the right size and
"looks" like aircraft cable.? Its kind of like "piano wire". You wouldn't put
piano wire from Home Depot in a Steinway, would you?.

Hi Larry,
The kit cable is not coated with vinyl.
I have compared the stainless cable with galvanized in the hardware
store. The difference is profound. The stainless is much smoother
and more flexible. I suspect it would last a lot longer and maintain
its length a lot better than the galvanized.
I suppose you could use either one on your plane. If your goal is to
get minimum cost with reasonable safety then the galvanized might be
the best choice. On the other hand, if you want the nicest feeling
plane you can get I suspect the stainless would be a better choice.
Good luck,
Paul

I've been lurking on the control cable subject and will add my comments
- I'd check with the FAA as a start. Up here in Canada there are strict
requirement standards on them by our FAA, one of which is that they must
have the minimum count of wires in each sub-wind and a minimum number of
sub-winds to the cable. I've tried to find the actual specs but cannot
put my hand on them. Anyone else out there can come up with the specs?
Wouldn't galvanized tend to crack and let moisture in and develop rust
or a weak spot?

| Subject: | New Rudder Question |
My Rudder is damaged and I had planned to replace it now that the fuse
assembly is nearly done. Has anyone talked with ZAC on weather the new style
rudder will fit the XL for sure? I work graveyards and when I get home from
work, ZAC is not open yet and when I get up, they are usually gone. 2 hour
difference from west coast.
I was at Arlington this year and Dragonfly Aviation had their brand new AMD
601XL there. He said it had just a few hours on it. One of the first things
I noticed was the rudder looked different. It had a trailing edge piece on
it and was very contoured on the top. It was a good looking rudder. I took
pictures of everything in hopes of duplicating it. Then here comes the 650
with the same rudder. So now that I need a new rudder, I would like to build
the new rudder if it will work. I just read the article that someone just
posted and it gives me hope.

Hello Bill:
Would you think it fair to add that the galvanizing on both the cable
and the boat trailer steel are coatings that protect the ferrous base
metals from rusting as long as the integrity of the coating is
maintained? If the coating is compromised through wear or damage, the
base metal is then unprotected and can certainly rust.
Stainless steel, on the other hand, is a very corrosion resistant base
metal that resists rust without a coating. Note: Even stainless steel
is not "rust proof". In extremely harsh conditions, it will corrode as
well, but there are many grades of stainless, many of which are very
corrosion resistant.
What are the arguments of Galvanized verses Stainless aircraft cables?
Regards,
Randy, Las Vegas
Galvanized cable does not rust. That's why boat trailers for
use in salt water are made of galvanized steel. Both galvanized and
stainless are available in like sizes from the supply houses. Both are
mil spec.

Galvanized steel, cable or otherwise, does corrode. Galvanizing postpones
the corrosion of the steel by corroding first.

There are a couple of issues in deciding between SS and Galv. First galv. cable
in the same 7 x 19 strands is more flexible and is also stronger.SS cable
is prone to cold embrittlement [high altitudes].SS is more corrosion resistant.Aircraft
good quality cable is also lubricated on the inside during manufacture.
Make sure if possible to pre- test load [stretch cables to highest load] all
your cables after Nico pressing or swagging. Cheers

when doing the proof load enclose the cable assembly full length in a piece

Chrome plating works that way but not zinc plating. If you scratch
through chrome plating on steel, the underlying steel will begin to
rust under the scratch. Zinc plating will protect the underlying steel
even across small gaps in the plating. The zinc acts as the anode in
the reaction and will oxidize before the steel. The steel will not
rust until most of the zinc has corroded away.
As I recall, stainless steel cable has a bit lower tensile strength
than galvanized steel cable of the same diameter and galvanized steel
cost quite a bit less.

a chemical reaction with the aluminum surface a bit like electro plating
and this layer would be removed or damaged if you then use an etch primer. Cheers
