Old floats might be coated with shellac. I wonder if this played some role in what
happened to my float a couple of years ago:

Jeff; you're may have something there... I have seen that blackened alligatoring
on old outboard motor fuel tank floats. Whatever the case, it seems like you've
solved your problem with the small aluminum bottle (non-TSO'd, non-STC'd,
probably no FAA Form 337, unlikely that it's in AC 43.13-1B "Acceptable Methods",
and not in the Bingelis books, so be careful). The cork float on Scout's
float indicator were dipped in epoxy when Corky made it (and there is some subtle
serendipity there, too). So far no sign of any problems with Corky's cork
float, but then again I don't fly auto gas and never have.
You should probably attempt expanded flotation testing on yours with something
besides pastis though. Ouzo is very good for this, so are mastika, raki, mezcal,
aguardiente, and Sambuca. See if the cork floats before you sink.

When I was younger I might have tried all of those contaminants, but now I'm pretty
much limited to beer, wine, and the occasional martini. Hey now, I think
I DO need to test whether olives or lemon twists float better.

While the Piet is down, we shifted the action cam over to another low-n-slow plane.
This is a link to a video of a flight my friend took yesterday in his Pup
(I flew it after him; no video of that). He rebuilt this plane while recovering
from his THIRD round of cancer. He says the Pup, his wife, and his docs and
nurses saved him -- he's just not sure in which order on any particular day!

Jeff,
Was it a vintage shellac coated float you epoxy coated? If possible my guess would
be that while epoxy coated, there was a pinhole hole in the coating somewhere.
Alcohol, being more viscous than either fuel or water made it's way in,
and attacked the shellac. Being coated, it deformed the expoxy and bubbled up
underneath, creating more holes and the system went south pretty quick.
It would create quite a gunk, a bimaterial layer of shellac/epoxy being attacked
from underneath.
It's really hard to coat a porous surface like cork. Shellac merely slows the
ingress of fuel to the cork, it's not a impenetrable coating. Neither is epoxy
unless really carefully applied.
If the surface isn't smooth and shiny like a plastic casting, there are holes somewhere.
Also, alcohol has an affinity for water, which is what rusted the coat hangar.
Gas doesn't, they don't mix and the water sits on the bottom of the tank and
corrodes it there. Alcohol dissolved in the fuel, holds the water and presents
it to the coat hangar so to speak.
Dot 4 and older brake fluid, has alcohol and does the same thing inside brake systems.
Dot 5 is silicone based and mnch better.

Well of course he noticed that he dropped a phone or radio or something as he exited
the aircraft? So what's up with the fuel venting out of the starboard filler
cap in flight? Just a full tank? Couldn't have been the fuel warming up
in the sun.
Wish he would have provided a side shot of the Pup...

Yep, he came back for it. I don't think that fuel was venting -- we were just
sloppy adding fuel at the beginning of the day. It shows up so well because Ron
needs to wash his plane!

Hello John,
I was wondering where I stand with news letters? I did get my last one back
in September or so off the Matronics web site. And the one before that from
you. Am I on the list to receive the current and the next one that will
come out in March???? Question?? I did make it to Brodhead this year. I did
buy 2 T-shirts while there. I did not look at them until I got back to
Alabama. They are great shirts but they are not the ones i had seen on the
Brodhead website. I was looking for the T-shirt with the Sky Scout design.
Do you know if they are still available?? Thank You!
Tony

Hi Tony,
Yes you are on the list for a few more newsletters. T-Shirts at Brodhead
are usually either sold by the Pietenpol family or by Pat Weeden. If you
are thinking of the red Sky Scout shirt, Pat told me he only had 18 of
those printed up.
Best,
-john-

Jeff: thanks. I was just watching the video and as the flight progresses, fuel
streaks back farther and farther aft from the cap as if it was streaming out.
I'd like to know more about what he powers it with. A 1/2VW? When he pulls it
through to start the engine, it seems to have pretty good compression. He seems
to fly the approach "down the slot" at about the same rate as your Piet, if
not maybe just a bit faster! Must be that enclosed cockpit, eh? ;o)
