Hi -
Does anyone know what the torque should be on prop bolts for a composite
Aymar Demuth (I'm sure I spelled that wrong) prop? Also for the bolts
holding the 4 inch prop extension to the crank.
Many thanks,
Parker

Not quite true.
Sleep apnea has profound effects on the brain and heart depending on severity and
duration. Even mild sleep apnea degrades mental performance and decision making
therefore placing the pilot and everyone on the ground under his flightpath
in danger.
Sleep apnea does its major physical harm over 20-30 years and the consequences
at that point are deadly,disabling and irreversible.
The proper course at this point is treatment and resolution of the problem, then
worry about tne medical and flying. The CPAP machine is essential in the treatment
and if persistently used he will get used to it and feel better for it.
He also needs to be under the chronic care of a physician who specializes in this
long term. He is correct surgery is not very useful.
Just do not delude yourself into thinking it is only a loss of sleep. This is a
serious medical problem.

Listers, I am delighted to tell you that RV6 VH ASF took to the sky for the first
time yesterday, 2nd April. She has a Superior 0360 engine, turning a wooden
prop, and weighs 934 lbs without paint or gear fairings.
At full power she climbs like a rat up a drainpipe, and is quite docile to stall.
Thanks to all of you who have helped me over the last 7 years, with advice, information
and encouragement. It's been frustrating at times - but now it is definitely
all worthwhile!

In even not so severe cases, a person with sleep apnea can fall asleep
during the day while acting as a PIC or a controller. Or as a driver of
a car.
A friend of mine wrapped his car around a lightpole a couple of years
ago after he fell asleep at the wheel. He woke up wondering how & why
he was in a wreck. Fortunately, he walked away uninjured. He was
diagnosed with sleep apnea and since then has been doing much better
with CPAP therapy.
It's definitely a serious condition, regardless of whether medication is
involved or not. However, it is not disqualifying as long as there is
effective treatment.

I am using 26 ft-lbs for the prop bolts on my Aymar Demuth prop. I do not
know if it is solid wood or wood/fiberglass.

Thanks to everyone that has helped me with their reply. I decided to use the Dremel
to cut the nut. I left a small amount of nut in place to help avoid damaging
the spar during cutting. The remaining nut was easily separated from the
bolt.
Now in my next adventure in plane building, I will learn about replacement hardware
purchasing...

I don't quite understand why sleep apnea would endanger your flight medical?
Is sleep apnea listed as a disqualification for a medical? You are not
taking any medication to control it, are you, and the only time you are in
any physical danger is while you are asleep.
The problem is the associated daytime sleepiness, big problem with over the road
truck drivers. One study showed a small percentage of truck drivers are clinically
asleep while driving 75,000 pounds at 60 MPH.
Adequate treatment should allow you to regain your medical but you may need a test
called a "Maintenance of wakefulness test". They put you in a room and dim
the lights to see if you can stay awake. Boring but proof that your ability
to stay awake is adequate. Show up for the test well rested and do not cheat
by using stimulants because they will probably do a drug screen.
CPAP and BiPAP are the standards of therapy but you need to make sure your nose
is working. Weight loss and surgery are good options. Staged surgery has been
shown to be as effective as CPAP but entails more pain and money.
I'm mostly retired now but have been able to get most pilots with OSA healthy
enough to get their medical back. OSA is a significant factor in people dying
young...if you have it, get it treated.

No one has mentioned it so far but all PAP machines have available a mask
that covers both the nose and mouth. So, if you can't breath through your
nose, ask for one of these. I had Apnea for most of my life without even
knowing there was a name for it (flew jet fighters for 20 yrs & DC-9/MD80's
for 12) then, 4 yrs ago (age 64), got diagnosed, went on CPAP and it's been
a whole new world. I hope you can work it out, it's certainly worth it.

Im moving into a hangar with a pretty steep ramp at the entrance, requiring

Im also considering buying an old junky mower to push it in but then I'll
have to come up with some king of tow bar.

I would not use the tail tie down, but rather get an old riding lawn mower and
use a towbar on the nosewheel instead.

Jeff,
I'll probably need to get my Nomex underwear back out, but I was faced with
this same problem. What I do now is taxi the plane into the hangar, and use
the tow bar and gravity to get it back out. That's been working very well.
That may not work for you, depending on the type of hangar you have.

--> RV-List message posted by: <erichweaver@cox.net>
Greetings.
Dumb-ass question of the week:
Which way does the prop governor cable work? That is, when you pull the control
knob out, does the pitch on the propellor increase or decrease?
Im installing the MT governor from Vans. It looks like I will have to cut the
exquisitely twisted safety wire on teh unit to allow me to rotate the case around
and point the control arm up. If I dont do this, the Vans support bracket
wont fit. The control arm on the governor is spring loaded, presumably so that
when my cable falls off, the prop pitch goes to the minimum value, allowing
full power and a safe return to earth. Given that, with the control arm positioned
upward, I will have to pull on the cable knob to increase the prop pitch.
Is that how its supposed to be?
Still lost in a fixed-pitch world,

Erich,
The prop cable does not control pitch directly, but RPM. Pushing the knob
in causes more RPM, pulling the knob out reduces RPM. So that means that
pulling on the cable increases pitch. But, its better to think in terms of RPM.

--> RV-List message posted by: "Pat Hatch" <pat_hatch@msn.com>
Erich,
The way to think about it is that you are actually controlling RPM, not
pitch, although indirectly pitch will also be changed. So, full forward is
maximum RPM, pulling the knob out decreases RPM. As long as you don't move
the control, the RPM should stay constant, although the pitch may change as
you increase or decrease airspeed.
The MT governor should have come from Vans clocked properly for an RV, but
it can also be re-clocked if necessary. You may have to call Vans or go to
the MT web site to get the instructions on how to re-clock the control.
Basically, you want the cable to be 90 degrees to the governor lever at
mid-range in governor movement. Check to see that you have the support
bracket oriented properly.
And the answer to your question is "yes": pulling the control cable aft
will decrease RPM and increase pitch and the lever is spring-loaded to the
max RPM position.

--> RV-List message posted by: <erichweaver@cox.net>
Greetings.
Dumb-ass question of the week:
Which way does the prop governor cable work? That is, when you pull the
control knob out, does the pitch on the propellor increase or decrease?
Im installing the MT governor from Vans. It looks like I will have to cut
the exquisitely twisted safety wire on teh unit to allow me to rotate the
case around and point the control arm up. If I dont do this, the Vans
support bracket wont fit. The control arm on the governor is spring loaded,
presumably so that when my cable falls off, the prop pitch goes to the
minimum value, allowing full power and a safe return to earth. Given that,
with the control arm positioned upward, I will have to pull on the cable
knob to increase the prop pitch. Is that how its supposed to be?
Still lost in a fixed-pitch world,
Erich Weaver

Jack:
It would also be a good idea to check the calibration on your torque wrench. The
first one I bought when I was starting my RV-6 turned out to be over 100% in
error in the 20 to 25 inch pound range for AN-3's (25 in lbs setting was actually
60 in lbs). Suffice to say that that one went back to seller accompanied
by a very nasty letter. BTW, the seller was NOT Avery or Cleveland.

The MT governors DO NOT come from Van's clocked
properly. I had to reclock mine as well.
Consider it an excercise in safety wire practice...

Jeff, running it in under power works but so does pulling it
in with a relatively inexpensive 12 volt boat trailer winch
(hooked to an old battery removed from the plane) hooked
to a cheap battery charger that is on a timer to run for
30 minutes to top off the battery after running the winch.
It pulls my RV-6A with an 1/8" cable hooked to the tail
tie-down into the hanger up a slight grade and over a
1-1/2" tall angle iron mounted on the hangar floor as the
support track for the Horton Stackdoors. The 12 volt
winch is turned on and off by a 30-foot long piece of
extension cord with a pushbutton switch at the end letting
me steer the nosewheel with the tow bar as the plane
is pulled backward into the hangar.
This scheme has worked for me at two residential
airparks over the last 25 years.

Jeff,
I'll probably need to get my Nomex underwear back out, but I was faced with
this same problem. What I do now is taxi the plane into the hangar, and use
the tow bar and gravity to get it back out. That's been working very well.
That may not work for you, depending on the type of hangar you have.

Im moving into a hangar with a pretty steep ramp at the entrance, requiring
some means of towing. Im wondering if the tail tie down is strong enough to
be used to pull the plane in.
Im also considering buying an old junky mower to push it in but then I'll
have to come up with some king of tow bar.
