| Subject: | Riveting in dimpled skins |
--> RV-List message posted by: Dan Charrois <danlist@syz.com>
Hi there. I asked a somewhat related question a little while ago and
got a great response from this list, but I'm still a bit unsure on
something. Please feel free to let me know if I'm being a bit
overzealous and shouldn't worry about this sort of thing.
As you probably all know, creating a dimple in a skin enlarges the
hole. An AN476AD3 rivet that would otherwise fit in a #40 hole nice
and snugly rattles around quite loosely when the hole has been dimpled.
My concern is having enough of a shop head on the end of the rivet
when set in two sheets that are both dimpled. I'm using the rivet
lengths as suggested by Van's (AN476AD3-3.5), which would make a nice
shop head if there weren't the enlarged hole in the dimple. But I'm
finding that the shop head isn't as large as I'd like, since:
1 - on setting, the rivet expands a bit more to fill the enlarged
hole, making the amount of material available for a shop head
somewhat less than if the hole fit more snugly.
2 - a larger shop head is needed to cover the enlarged hole
comfortably than if the hole weren't enlarged.
In particular, I'm finding that if a rivet bends even slightly while
being set (even if the tail moves 1/64 of an inch or so off
vertical), the shop head doesn't appear to completely cover the
enlarged hole (at least, with any kind of overlap - it's not that I
can see through to the other side, but one edge of the shop head
seems to my eye to be lined up pretty evenly with the side of the
hole). And it's all too easy to have a slightly bent rivet with it
rattling around loosely in the enlarged dimple hole when I'm trying
to set it. I've tried the trick with a rubber washer on the shop
end, and though it seems to help somewhat, some rivets still don't
seem to cover the hole all the way around with a comfortable (at
least to me) overlap. It's most obvious when viewing the head from
the side, as on one side, the raised skin of the dimple rises up
significantly higher before meeting the shop head than on the other
side.
Is this a common problem, or am I just being too particular? There
doesn't seem to be a way of creating the dimple without enlarging the
central hole, as after all, the aluminum just stretches when making
the dimple. Drilling the hole smaller wouldn't help, since the
dimple die's central pin would enlarge it to a #40 anyway. It seems
the ideal situation would be to use rivets a bit larger in diameter,
but that's not what the plans call for (and such rivets doubtless
don't exist anyway, unless going all the way to an "oops" rivet size,
which is definitely overkill).
A longer rivet wouldn't help, since it's tough enough to keep them
relatively unbent as it is.
What seems to be an ideal solution would be to drill a somewhat
smaller hole (like #43 or something) and use a dimple die with a
similarly sized central pin, which would then enlarge the rivet by
the dimpling process to an end size of #40. But I doubt that such
dimple dies exist, and that just doesn't seem to be the "way it's
done" anyway.
Since I can't imagine how anyone wouldn't have this problem, and the
plans don't call for anything special to be done, I'm left to
conclude that I'm just probably being overcautious. I guess I can
have some consolation that rivets aren't intended for tension forces,
but rather shear forces, which shouldn't be as affected by the rivet
shop head not having a significant overlap over the dimpled hole.
That, plus the fact that Vans tends to overengineer their planes so
if the odd rivet popped its shop head out through the skin it
wouldn't be a catastrophic problem.
I'm just curious as to what others' thoughts are on this, not that I
know what could be done about it anyway (of course, if I'm missing
something obvious, please let me know!). I know that some may say to
stop overengineering and just do what Van's instructions call for.
But I'm the sort of guy that likes to know *why* something is okay
instead of just accepting it because "that's the way it's done".

Dan,
I wonder if you are deburring your holes too much. Yes, the hole is
larger after dimpling but not so much that the correct set rivet doesn't
"fill" the hole. If you deburr too long it's like using a machine
countersink on the hole before you dimple. This can make the hole way too
big. (ask me how I know, ha,ha)
I just gave each hole about two light turns when deburring. This might be
the problem.
Later,
John

Your evaluation of the problem is spot-on. You can find hundreds of
messages in the archives emotionally championing various positions on
the subject. The only technique I've seen that doesn't provoke a strong
emotional negative response is to start with a longer rivet &
'presqueeze' it slightly in a hand squeezer to fatten the shank of the
rivet. The technique works, but is very time consuming & it's a pain to
do the presqueezing & get exactly the right amount of fattening without
tipping the shank on the head.
Enjoy....

I just want to expand on the deburring. The correct way to deburr is to
lightly turn the tool just enough to smooth out the protruding metal and not
start countersinking. If you notice a countersink, you have probably used
too much pressure or turned the tool too many times, or both. You want to go
just enough to feel a smooth skin when you run you hand over the holes. I
hope this helps.

| Subject: | stainless steel hole cutter |
--> RV-List message posted by: Mickey Coggins <mick-matronics@rv8.ch>
Hi,
I'm trying to cut about a 2" hole in about 1/8"
stainless steel, and found out that my trusty
fly cutter, which works so well on aluminum, has
a very hard time with SS. I was turning the
thing very slowly, with lots of oil and pressure,
but no dice.
On Monday I'll probably take it to a machine
shop, but I was curious if there are any tips
or tricks that I'm missing.
BTW, this will be for a firewall penetration
seal.
Thanks,
Mickey

I've had a couple of folks say they can't find my home airport in the
AOPA 'real time flight planner'.
I got around to trying it for the 1st time today, & sure enough, MS71
isn't found. I then clicked on the 'help' tab and at around a half hour
or so, I'm still waiting for the 'help' file to load (around 17 megs, so
far).
Not exactly 'real time' for those of us stuck with dialup....
Does anyone know if they only include airports for jet jockeys?

Perhaps because it is private and seems not to be even a US airport:

Well, we did try to secede a while back, but it seems that the Union
just couldn't survive without us.
'Private' doesn't mean 'outside the US'.
A flight planner that ignores private airports won't allow much planning.
Ahh, well... I guess their lobbying efforts are worth the membership cost.

Charlie, if it makes you feel any better, Aeroplanner.com's EAA flight
planner knows where Slobovia Outernational is located. :-)
Seceding might still be a good idea, however.

On my firewall I have used a metal hole saw cutter. It chucks into a drill
and you must buy the exact size for the hole you want. It works as well as
any other technique for stainless. But, nothing is easy when it comes to
cutting stainless steel, or any steel for that matter.

I have the same problem with my home airport. My solution is to enter a
nearby airport that the flight planner does recognize, then I open the en route
map, drag and drop the end of the course line on the airport that I want and
the program will recalculate the complete flight correctly. Some times you
will have to zoom in to get smaller airports to show and if your airport is
"unverified" it will not show at all.

For what it's worth, I overheard one of Vans' employees at Arlington last
year talking about deburring... He says they deburr skins with a
scotchbrite pad. Just run it back and forth along the line of holes a
couple of times, and then do a quick visual check that no material is
trapped in the holes. It seems to work quite well, and almost guarantees
you won't get any unwanted or inadvertent countersinking.
Of course, this may not be an ideal method if you plan on polishing your
skins instead of painting...

I have never used the system but can you show that ALL private airports
are not included? If AIRNAV can show it perhaps you should call AOPA
and have them remedy the error.

Looking to make a cowl flap that I can operate from the cockpit for my RV-4.
Does anyone have any pictures or plan I might look at? I have my oil cooler
blocked with aluminum tape and also restricted the cowl inlets approximately
one third. Finally got my oil heated up to 185 F. Without the cowl inlets
restricted, can only get about 120 F on the oil. Not sure whether to restrict
the inlet or outlet flow. Any advice? Thanks in advance.

Pat;
Does your engine have a Vernatherm valve in the oil system ? If so it may
be sticking in the open position; this allows the oil to circulate through the
cooler all the time. The Vernatherm valve allows oil through the cooler
only when the temperature reaches a certain point.
You can remove the Vernatherm valve and submerse it in a can of automatic
transmission fluid , heated with a propane torch. You can put a candy
thermometer in the can to keep track of the temperature up to 400 - 500 degrees.
BE
CAREFUL !! That is HOT !!
You can see if the valve moves and what temperature it reaches when it
moves.

Lately my GPS seem to have a problem picking up the satellites.
It's been taking longer to get a good lock and a couple of times it
dropped the signal in flight.
Today I was about 10 minutes into the flight before it got a good signal
than after about another 10 minutes it lost it.
This is Garmin GPS 150 panel mount about 10 years old.
I'm thinking either the antenna connections or the antenna itself. Do
the antennas go bad?
Any Ideas on how to check it would help.

I am fortunate to have access to Greenlee chassis Punches. You might check
their site www.greenlee.com to see if their punches will work on 1/8
stainless steel. I used them on the firewall itself and they work really
well.
Down side is that they're not cheap. But the machine show you mentioned may
'rent' them to you for the one or two holes you will need.
They have a line that an electrician would use for running conduit. You
might check with local electricians to see if they have them at the size you
need.

Hi,
I'm trying to cut about a 2" hole in about 1/8"
stainless steel, and found out that my trusty
fly cutter, which works so well on aluminum, has
a very hard time with SS. I was turning the
thing very slowly, with lots of oil and pressure,
but no dice.
On Monday I'll probably take it to a machine
shop, but I was curious if there are any tips
or tricks that I'm missing.
BTW, this will be for a firewall penetration
seal.
Thanks,
Mickey

Bud, you might look for ignition noise as the culprit.
Turn on the GPS and let it stabilize. Check the time in the GPS too,
as correct date/time helps the unit acquire satellites faster. If the
date/time is wrong, it'll be looking for satellites that may be over the
horizon .... and not receivable. If you get a good lock and it stays
that way for 1/2 hour (you may need to hook up a battery charger to
prevent running down the battery) on the ground, start the engine and
see if it loses lock like it did before.

10 years old means the internal battery is most likely dead.

There have been references to the internal battery. That may be the case,
BUT, I seem to recal some time ago there was a change in the satellite
datastream and all older GPS's needed to be updated. Don't know if this is
the case with yours but something to consider **IF** it is not a battery
problem.

Hmmmmm
Worked for me!!! (AOPA RTFP)
Seems that MS71 is on the 258 or 159 degree radial of the JACKSON VOR,
Southeast of the OCARO intersection.
It even knows it as Slobovia Outernational, 1 mile N or Pocahontas.

| Subject: | Dynon Failure Mode |
--> RV-List message posted by: "Larry Pardue" <n5lp@warpdriveonline.com>
Greetings:
When I was evaluating the Dynon D-10A for purchase I decided that one thing
that made it compelling was the failure modes. The mechanical gyro
instruments tend to fail in a way that makes them dangerous. If a vacuum
pump fails, the instruments slowly give worse and worse information. I had
worn mechanical gyro instruments that were inconsistent, sometimes working
fine and sometimes giving erroneous readings. I figured the Dynon would
either work or not. I was wrong.
Today, after takeoff, I noticed the Dynon was not right, first because zero
rate of climb was indicated when I was climbing about 1,500 fpm. Then I
noticed more and more problems. The indicated altitude was about 27,000
feet and the airspeed was about 410 knots. My RV-6 is a high performance
airplane, but not that high performance. I turned the instrument off and on
several times. Nothing helped. The heading seemed roughly correct but was
not stable and hunted through several tens of degrees. The attitude
indicator was sometimes about right and other times drifted to completely
wrong attitudes.
All in all, this is disturbing to me. Guess I will contact Dyon on Monday
for advice and I am hoping I can just reinstall system software or
something.

I have a GPS-150 in a Cessna 170 since 1993 (+ or -) which I flew until
November 2004 when I started flying my RV6. That GPS had a dead internal
battery and all I had at start up was a message saying "Battery Requires
Service" and my user waypoints would be lost. It still functioned normal
in all respects with the Garmin database chip (Jeppeson data) and all those
fixes worked fine meaning I had no reason to replace the battery. Garmin
wants a flat rate $250 to replace the battery and will not supply dealers
with parts as they did a few years ago. I prefer to just fly the RV6 with
a new Garmin GNC300XL so this unit now sits.

Your right Garmin wants way to much money to replace a battery, when
mine went dead in my panel mounted
FlyBuddy I opened it up and found the battery, (they are the soldered in
type) and got the number off of it and
found a place on the internet that sold that type of battery. It was
pretty easy to unsolder and solder in the new battery.
Has been working great since with no loss of signal. The way Bud
described his problem sounds just exactely like what my
FlyBuddy was doing.

This happened to me the other day on my handheld. I later discovered that I
hadn't completely plugged the external antenna in all the way. It was
trying to find its way with the internal antenna while buried down where it
couldn't see all the sattellites. Double check your antenna connections.

Hmmmm, indeed. Zooming the map shown at startup will show MS71 but if I
click 'preflight' > 'plan route' & enter MS71 in either the departure or
destination field, it responds "No airport was found corresponding to
'MS71....." Did it work for you entering the identifier on the plan
route popup?
I've never used this flight planner before; the only reason I noticed
this is that I've had people tell me twice that they couldn't find it
using AOPA's flt planner.

Sorry you had problems with your Dynon. But it sounds like you
experienced exactly the kind of failure mode you expected from the
Dynon; the unit definitely wasn't working and there was no way you would
be tempted to use it as a flight reference.
I'm confident you and Dynon will be able to quickly solve the problem.
The Dynon seems to be racking up a solid reputation in the field and
there is obviously a gross error in the pitot-static section of your
unit or the software has been corrupted. Just be thankful that the kind
of failure you described for the vacuum system is not likely to happen
with the Dynon.
