I was always taught "Best Practice" is never to reuse copper sealing
washers, replace with a new one every time. At the very least a used one
should be annealed before reuse.

Guys,
I=99m looking for a prop (one blade) that I plan on using as a door
stop.
The wind keeps blowing my hangar door shut and I=99ve got this idea
for a neat
door stop. Condition or paint does not matter, or even if it=99s d
amaged
or corroded and totally un-air worthy. But if its taking up space in your
hangar, I=99ll pay you $30.00 and shipping. I=99m thinking the
re may be a
couple of Chinese props laying around out there.
Off list I guess.

I'm assuming those boots are to replace the 4, sticks, flaps, nose strut.
I picture of one installed would be great.
Nice work!

Copper crush washers and new plugs for the air tanks are in stock if you
need them.
And no, they should not be reused. However a word of warning do not try
to remove the plug with anything less than a tight fitting box end or
socket. A open end or your good old "adjustable metric spanner" will lop
off the the hex corners, then your only option will be to weld a piece of
bar stock to the plug in order to remove it.

I felt this spot on my prop and thought it was a ding. It was tough to really see
it before I removed the paint. The pictures make it look deeper than it is
and of course I don't know how far the "worm" goes. I'm sure it's been flying
this way for a little while. My gut feeling is to get two brand new blades from
Doug. I'd love to hear anyone's 2 cents worth.

| Subject: | Re: Hydrostatic tests |
A number of years ago, after a hydrostatic test, we installed a new copper
crush washer as tight as possible with a 12=9D socket. A week later
we
started experiencing an air leak that took a few weeks to trace. Eventual
ly an
ultrasonic leak detector pointed us to the main tank drain. A further 1/16
rotation on the plug, using an 18=9D =9Cbreaker bar=9D p
ipe, stopped the leak
instantly.
As Doug suggests, given the torque often needed to secure this plug,
invest in a good 6 point (not 12) socket or wrench as you will likely roun
d the
corners without one.

Hi,
instead of copper crush washers Id rather go for an O-ring design in this place.
You would not have to apply that high torque to get a decent seal and could
reuse the o-ring a few times. We are running an 18 T for 7 years now and never
ever had water in the bottles since. But certainly we drain the system at the
fire wall in the very first minute after engine shut-down -- everytime. Nevertheless
I use clear motorbike chain grease for rust protection in the bottles
and they still look new inside checked by endoscope.
Cheers
Vic

| Subject: | Re: CJ prop - intergranular corrosion |
Years ago one of CJ guys found a prop where the Chinese found corrosion had
filled with bond-do and repainted. I and Jeff Linebaugh found both his
props with large integranduar corrosion at the blades mid point. He got a
new set (still in factory box) of blades and found the tips badly corroded!
If money is a concern but still want to be safe, I'd send the props to a
good prop shop. Have them strip and x-ray the blades. Let them determined
if the blade is repairable i.e. file it smooth and re balance both blades.
That far out on the tip, the blades performance will not suffer as there
is a lot lost out there anyway. This type of corrosion is from the
quenching process when the blade come out the furnace.
I've seen blades with larger damage than that repaired in the field with
the blessing of the manufacture. A good prop shop can use the same rules of
like props to determine what to do about yours.

Are there any shops you might recommend down here in FL, or wherever...
