The fuel/air mixture over the liquid in a gasoline tank is too rich to
burn. The fuel/air mixture over the liquid in a diesel fuel tank is
too lean to burn. In either case, a spark will have no effect. In a
tank used for jet fuel, it's a different story. The vapor pressure of
kerosine falls somewhere in between, so there might be a real hazard
there.

All good questions to be aware of. I wouldn't say any one person is an authority
hence the useful thread to get everyone opinion.
Personally, I'd say any spark at any voltage is not good, but generally sparks
need a lot of voltage, even static electricity from your body to the house lightswitch
from walking across the carpet is something like 10,000 volts, but almost
imperceptible amperage. But a 1 volt spark is possible.
Just to be safe, I'd insulate any 'hot' lead just in case for some reason (rattling
tank, dent in wing skin) causes it to touch something grounded.
On another note, I recieved my Gas Welding Aluminum kit from Ron Fournier yesterday.
Awesome video. He made some really nice looking welds right there in realtime
on the video, one for a fuel tank even, and it didn't look all that difficult,
it looks mostly like common sense and he did a good job explaining what
he's doing. VERY nive looking actual welds, not brazed. He also showed how to
not weld aluminum and how to just burn right through the material. The thing
that I found interesting was that when he burned though the aluminum while demonstrating
how to NOT weld was that the aluminum didn't flow away UNTIL he poked
the filler rod in it, which would suggest to be that basically what he did
was break the surface tension of the pool by feeding too much filler into the
weld pool that had too much heat in it. While demonstrating proper welding it
was done with just quick little dabs with the filler. While fusion welding he
just moved flame slowly over the joint and he actually had the flame in contact
with the aluminum a lot longer than I would have expected, so it seems that
not disturbing the surface tension of the weld pool too much is another key feature
of aluminum welding. I'm looking forward to trying it this weekend.

Don't forget that if the wire from the gauge is disconnected/broken at the
sender there is 12 V on that mother when no current is flowing. It will
spark.

They never saw an Apollo capsule burn up 3 people before Jan 28, 1967 either, til

These are vented tanks, correct? What is that vent develops and crack and the vapor
leaks into the enclosed wing area. I'd say taking precautions never hurt
anyone. Treat it like what it is, explosive gasoline. Caution is never a bad thing.
That XL that went down in flames in CA, who knows, maybe that had a venting problem
and a spark caused the tanks to explode.
Speaking of vented tanks, why are car fuel tanks not vented? Or should I say, why
are airplane and boat tanks vented? They even test the cap at the inspection
station to make sure it holds pressure.

All fuel tanks are vented because of pressure that builds in them. I'm sure
there are some Cessna owners out there that can remember the day they went to
the airport to fly on a hot day and it looked like someone put a balloon in
you wing because the vent got clogged an expanded tank can pop out rivets and
severely distort the metal.
Cars also have a vent it is in the filler cap.

Cars have vents too? So what is that gas cap test then? I thought maybe there was
a checkvalve in it to only allow air in as the fule level goes down. Every
time I take my gas cap off of any of my cars they go ""Scheeewwwww" as the pressure
is released.
I was under the assumption that cars didn't have vents, at least cars that have
feed and return to the tank fuel lines. I know my Nissan pickup has a return
line to the tank.
I'm not doubting you, just curious. Is it possible some are vented and some aren't.
As far as ballooning, I know if I leave my mower fuel tank out in the sun
it will balloon a bit. I guess that would not only possibly disrupt the wing
skins (especially if it's a wet wing) but also be bad for the tank welds if it's
a welded tank.

George, I'm not sure if this is an apples and oranges comparison or not, but I
bought a vertical card compass form an outfit called "Falcon Gauge" for my fat
ultralight a few years ago. Their stuff is reasonably priced with the vertical
card compass being a bit over $200 . The gauges are Asian made and mostly okay
but the vertical card compass went haywire almost immediately. Apparently
the linkage is rather delicate and the vibration made it FUBAR in no time at all.
I don't know if Falcon instruments are the same stuff as what I got from Falcon
Gauge but beware.

John,
I would say its not deadly but some attention may be necessary. Can you catch
the scratch with a
fingernail? If so it is probably worth taking out. I had some rather deep scratches
perpendicular
to the aluminum grain on my rudder spar and I used 400grit alum oxide paper to
get them out.
Since it was is the spar I went with the grain also. If they aree minor scratches
you may get
them out with some (MAROON 7447 3M Scotchbrite Pads). Whatever you choose to use
make sure it is
not iron (ferrous) based material. Silicon or Aluminum Oxide is the choice of
content.

>I have been looking for a Falcon Vertical Card Compass.
George, I used a few Falcon instruments when finishing up my HDS five years ago.
None of them are still in the a/c - and all of them were given away; no way
I could accept $ for the quality being "gifted."
Look into a PAI 700 vertical card compass. With over 300 hours on mine it works
fine; even during flight reviews the compass allows me to roll out very close
to instructed headings, and this without an attitude indicator in the plane.
The PAI is TSO'ed and once some flying club members got onto it they installed
units into both of the club's 172's. No issues.
Jay, as you said, not to start anything but what "research" did you do and what
results did you find? How much real world time do you have flying with TSO'ed
vertical card compasses? What issues arose?

I recall a thread about the Falcon Vertical Card Compasses in the past year
or so on one of the forums I read. My recollection is that the Falcon
compasses were not reliable, and that replacement was not possible. I
suggest that if you want a vertical card compass, buy the Precision
Vertical Card compass for $270 from Aircraft Spruce or wherever. On the
other hand if you want an inexpensive compass, buy a standard panel mount
compass like the one Van's sells for $100. Either way, you'll get a
reliable instrument. I suspect that it is not cheap to manufacture a
reliable vertical card compass.

| Subject: | Re: 601 XL 15 gal. fuel tanks. |
An empty gas can (with no liquid left inside) may contain an explosive
mixture. A gas can that has had a large portion of the liquid recently
poured out of it and fresh air vented in to replace it may contain an
explosive mixture for a while but soon, the vapor coming off the
liquid will enrich the mixture well beyond the upper explosive limit
and create a non-flammable mixture.
I was referring to a vehicle gasoline tank. There are damn few
situations where a flammable mixture can form inside a gasoline tank.
You would have to somehow get enough air into the tank quickly enough
to purge most of the vapor or drain all the liquid and let it set
until enough air has diffused into the tank to create a flammable
mixture. Fires involving a vehicle's gas tank generally start from an
ignition of vapors leaking outside of the tank. Gas tanks just don't
explode like they show in the movies.
I mistakenly thought the post I was responding to was referring to a
spark inside the tank. A spark in the space between the tank and the
wing skin is a different story. I can see a situation where a
flammable mixture can form in there. Even so, it takes a pretty hot
spark to ignite gasoline, I don't think you will get that from
shorting out the wire from the fuel gauge. The voltage is low and the
current will be extremely limited by the resistance of the gauge.
There's a reason why you need an ignition coil generating several
thousand volts to ignite the fuel charge in the cylinders. In any
case, I made damn sure that there was no possibility of my senders
shorting out. I stuffed enough cork padding around that area to
prevent any contact with the wing skin and then covered the sender
terminals with insulation.

Brad
When you get to the point of drilling those longerons together along with
the doubler, pay close attention to your edge distance and distance to the
bend. My holes are a little close to the bend inside the doubler on account
of the height of the stack. Wish I would have spent a little more time
analyzing this before I drilled. Becomes kind of a tight squeeze because the
side of the extruded L is short. Better to be close to the bend than to the
edge I reckon though.

Jeff, what you have to lose is time if your inspector won't approve it. The inspector
or DAR might pan such a cheapie as regulations require a compass. Would

In the apollo I disaster, they were using pure oxygen at 20 psi, five
psi above ambient pressure to simulate the pressure differential the
capsule would see in space. Anything that can burn will burn really,
really well with that much oxygen present. Oxygen at 20 psi is just
f**king dangerous.
Car fuel tanks are not vented because the EPA says they can't be
vented. Gas fumes used to be a big contributer to smog. Now the EPA
requires that gasoline vapor emissions be tightly controlled. Boats
and airplane gas tanks are vented because there aren't millions and
millions of them running around on in the big cities and the EPA
hasn't bothered to go after them, yet. There has been some talk about
requiring stricter emission controls on lawn mowers though.
According to the reports I've read, the Zodiac that went down in
California may have had a fuel leak in the engine compartment leading
to an explosion.

Cars used to have vented fuel tanks, now they have elaborate vapor
recovery systems involving charcoal canisters, check valves and many
feet of tubing. They probably still have relief valves in case the
pressure in the tank gets too high.

I originally had a Hamilton vertical card compass in my Zodiac. It
worked fine when it wasn't actually in the airplane but I couldn't
find a place either in the panel or on the glare shield where I could
get the thing properly tuned in. It was too bulky to hang from the
canopy. One day I saw an Airguide automotive compass at Walmart for
$10. It had azimuth markings in 10 degree increments like an aircraft
compass. I bought it and put it in my Jeep. I went through the
calibration procedure detailed in the instructions and soon had it
working accurately on all headings. I started wondering how well it
would work in my plane. I attached it to the canopy above the glare
shield and took the plane out on the ramp to do the calibration. In a
short time I had the compass reading with acceptable accuracy on all
headings. After a short test flight, I ripped the vertical card
compass out of the plane and put it up for sale on eBay the next day.

The DAR that tells you what to put in your airplane is not doing his job....
His job is to inspect your aircraft and make sure it is in a "Condition for
safe operation" and if he wouldn't give you an airworthiness certificate
because you had a cheap compass than you my friend have pissed off your DAR. If
you were correct in your assumption then he could also say you can't fly with
that Stewart Warner Tack or that car motor. The Dynon is not TSO'd either.
Just because something costs more doesn't mean it's better or not worthy of

OK,
this is for those of you with TD's out there;
I am seriously considering replacing all A4's with A5's in the rear
fuselage.
My assumption is the following; Yes. using all A5's will increase the
weight. Nominally (5#, maybe 10, but I doubt this much) Maybe not the entire
tail, I guess the turtledeck could be A4's but I am looking at taking this
trade-off for the increased strength. I am thinking about all the abuse the
tailfeathers will take once I start three-point landings.
Any thoughts?

if i set it on the glare shield, it absolutely refused to point north
or south and I used non magnetic tools to install and adjust it. If I
could have found a way to mount it up on the canopy where the Walmart
compass is mounted now, maybe it would have worked. But if the $10
compass works why bother with the $200 compass. I do my navigating
with a GPS anyway and I also have a DG. The only time the compass
comes in handy is to reset the DG on a cross country flight.

Exactly, if your DAR refuses to give you an airworthiness certificate
because of your compass, fire the son of a bitch and find someone
else. He obviously doesn't know his job. There's no requirement for an
aircraft approved compass in a home built.

Brad,
Rivet size is determined by the material and loads that are being
supported. To arbitrarily put in A5s you place excessive loading on the
thin materials,
you limit your options when you miss the size and have to go to the next
larger to compensate and you gain none of the material strength by using
A5s where A4s are specified. Stay with plan "a" would be my recommendation.

I recently went through this dilemma. I just "barley" started the rudder, but I
couldn't start anything until I came up with an affordable engine. I have WWs
Corvair manual and am still anxious about his buddy's 701 project, but I'm
not holding my breath. The VW to get any performance needs water-cooled heads.
These are available but by the time you add these and the re-drive, you are getting
pretty close to the weight limit. This left the Suzuki. There are several
re-drive mfgs, but they really don't provide much info about the engine, or
even the re-drive for that matter.Send me an email and I'll send you what info
I have found. There are some 701/Suzuki builders on this site that recently
got their tail numbers so keep checking it out as they have promised info.

Hi guys:
Yesterday, December 3, 2007, my four+ year project left the ground for
the first time as an airplane. It was only a baby step and we shut it
down to check everything out after the first hop, but all looks good and
first flight will take place when we get good weather again. Here's a
video I took:

I can't describe how fantastic it feels to see your airplane fly for
the first time even if it is just a hop.

| Subject: | 601XL-TD Question |
I often find myself agreeing with Larry, he is a very smart man. Other
then the reason Larry outlined take into consideration that the 601
series is 27 years old now and the Tail Dragger version was far more
popular in the early models. These used A4 rivets and are still using
them today with many hundreds of trouble free hours. Don't bother
changing something that has proven not to need changing. Adding strength
when not required is of no value. However, if you really want a stronger
Fuselage then flush rivet it. It doesn't need it one bit but It makes
for a flat surface for painting and esthetics on the paint job is a
better reason then using A5's which add little or no benefit.

I find a compass a useless piece of avionics in today cockpits. With my
Dynon/Sensornetics and GPS why the heckdo I still need a compass. Oh
right the Canadian Government will not give me a flight authority
without a =93Whiskey Compass=94 Not a remote compass like my Dynon, not
a
card compass or a directional gyro but a Whiskey Compass.
I think I have finally figured out why!! If I go down in the frozen
north wilderness of Canada I can crack open my whiskey compass and drink
the contents, blindness would follow shortly. The fine gov officials
know that I would not want to see just how screwed I am after they cut
spending on our search and rescue resources again.

The DAR that tells you what to put in your airplane is not doing his
job.... His job is to inspect your aircraft and make sure it is in a
"Condition for safe operation" and if he wouldn't give you an
airworthiness certificate because you had a cheap compass than you my

then he could also say you can't fly with that Stewart Warner Tack or

Jeff, what you have to lose is time if your inspector won't approve it.
The inspector or DAR might pan such a cheapie as regulations require a
compass. Would they allow it if you have an EFIS with compass? Better
ask.

If your nail is stuck in it then mild buffing is in order, but since it
is on the skin I would not worry too much, the properties of 6061 will
allow it to stay resistant to corrosion. If you are buffing your plane
then it will come out. If your painting then a small amount of putty
will remove all trace. Once again this is for a skin in which we have a
scratch that we are not worried about becoming a crack. If this was a
spar then all trace would need to be removed.

Zenith no longer gets their Avex rivets from the UK. There is only one source and
that's in China. The UK plant is no longer producing these rivets. The ones
Zenith purchases are from the same source as Aircraft Spruce. There is NO DIFFERENCE
except that Zenith runs random tests. Don't believe me...call ZAC and
ask them. I did.
