Bob,
the AN3 bolt has a 10-32 thread. The torque limit depends on the type
of nut used with the bolt. When using the Nylol 10-32 nuts, the
prevailing (minimum) torque must be at least 8-inch-lbs. However, the
maximum torque to use depends on whether or not the application puts the
bolt in tension or shear. The values in Table 1 should be followed .
Inch-poulnds is correct for the small bolts. Special steel bolts for
propeller attachment will be spec'd in ft-lb. For engine bolts follow
the manufacturer's values.
A lot of the AN and NAS designations appear to have been supeceded by
MS numbers. I find the people at Genuine Aircraft Hardware Co.
(888-247-2738) very helpful in sorting out the equivalent numbers.
Quite a few of the hardware numbers on the ZAC drawings have been
superceded, by the way.
Hope this helps.

any of these would be AN-3 bolts. I've looked through the Spruce catalog for
hints as to which thread size would be the AN3, but am coming up at a loss.
It seems like it must be obvious somehow, but I can't find it. (Incidentally,
these torques for the Fine and Coarse Thread Series are given in "INCH-POUNDS"
instead of foot-pounds, which I assume is a typo error---what do you think?)

| Subject: | RE: CH601 HDS POH |
--> Zenith-List message posted by: Phil Raker <phadr1@yahoo.com>
Jeff,
I believe the answer to your question is yes and no.
Yes, there is at least one HDS POH out there. George Pinneo, who used to
post on this list quite often, has written one which is posted on the ZAC site
at: www.zenithair.com/bldr/bldrinfo/gp-n44pz.htm
This could at least serve as a good starting place for writing your own.
No, I don't believe there is one with the kind of graphs, charts,
diagrams, etc. which are common in the POHs of factory-built planes. They put
lots of fancy stuff in the books to hide the fact that they're building brand
new 40+ year old airplanes. I don't believe the FARs require that the POH take
any particular form, just that there be one. If all the information necessary
to fly the plane safely can be put into words, the graphs & charts would be
redundant. (Do you really need a chart to figure out whether the W&B is within
the limits?)
Take a look at George's. It may not be the way I'd write the handbook,
but it certainly is a good starting place.

Jeff,
George Pinneo's handbook for his hds is posted either on the zenair site or
(also?) on the 601.org site. It provides an excellent base document you
might use.
I had a really nice one made up for my aircraft -- until a recent computer

For those thinking about the nose fork doubler for the 601XL, I just
received mine from Zenith. The unit comes with the associated bolts
and nuts needed for assembly. Since I do not have the facilities to bend
this
size metal, it was well worth the 40 bucks.

Flying 601 tail dragger pilots
On landing roll out while braking, is it necessary to be manipulating the rudder
pedals in addition to the brake pedals in order to maintain straight fast taxi?
The reason I ask is that I am in the process of building the brake pedals and would
like to get the most efficient braking possible. My calculations indicate
that I need at least 4:1 mechanical advantage in order to get 500 PSI w/o stretching
the air frame. So I need to decide the proper relation between the pedals.My
goal is to modify or not use the normal 'toe brakes on the rudder pedals'
as it seams that this is where lots of people are having problems getting sufficient
brake authority.
I have gained much knowledge on this list from other people's experience and thank
you all!
Happy new year

My office will be quiet for a few weeks so this would be a good project for

Dear Thread, on the fork doubler. I already have the brackets for the wheel
pants fitted and riveted on the old fork. I received my doubler and it
extends below and onto the brackets. Fitting that bracket and the pants just right
was a real bugger so I call Roger at ZAC to find out where the cracks had
appeared that required the doubler in the first place. Roger said the cracks were
all up around the six bolt area and that if I needed to trim half inch or so
off the bottom of the doubler so that it did not interfere with the pants
brackets there should not be any problem. For you fellows that haven't mounted
the bracket this it is not a problem. Another word on the wheel pants. Before
putting the main gear axles on and setting the fuselage on the wheels, have the
two holes in the end of the axles that hold the wheel pants brackets for the
mains drilled and tapped for threads. I didn't and I lost a couple days
disassembling, take to machine shop and reassembly because I didn't look ahead.
Happy New Year!!!!!, Bill of Georgia

Because of medical problems I'm forced to give up my project. Inc. are complete
plans, completed rudder. Stabilizer has some drilling done but not complete.
Also inc. is electric trim kit, several tools, clecos, drills, special heads for
rivets. 1,000 for all. Was going to use a continental so I also have a 0-200A
engine case yellowed taggeg by divco a accessory case, cam gear, crankshaft

Hi Everyone,
If it all works out with the French authorities, I will start what I think
is the first 801 in France next year. That takes some extra paperwork. Any
builders nearby Nice do get in touch. Especially if you were first to build
a type in France, advice welcome!
Happy new Year

I have a CH601HDS taildragger with factory suppled Maco breaks and rudder
pedals. I received my kit in 1997, so I had to modify the toe break
geometry to the latest ZAC configuration. I have NO problem with sufficient
break force. We have a grass strip, but concrete runup pads. At 5,300 RPM
static (Rotax 912), the plane creeps on the concrete but the wheels do not
turn.

Hello all you great list members.
I wish you all a very Happy New Flying Year. I hope this year will be as good or
better for you than the past building and flying year. I am looking forward
to fly my five year old project this fall or summer. Something big and major unforeseen
can only change that plan.
It looks like all the metal and gathered material for the past five years will
become an airplane and finally become something very joyful for the owner, who
has been dreaming of this moment since the year 1999. I know this is a slow
process, which could have been finished in a shorter time, but in my case was
only considered as a hobby ( my wife speaking). If it was up to me, one year would
have been the correct estimate, but who am I kidding.
I would like to use this time to thank all of you who have been a great help in
the building process, always ready to share your expertise and building experience
when you have been asked, which just shows what kind of nice people we have
on this list. For someone like me, all alone up here in a deserted island,
trying to cope by my self, this project would have been an impossible task.
I thank you all for your help and am glad I have found this great companionship
in the list Matt has made possible with his priceless effort.
Best wishes from Iceland.
Johann G.

It is sometimes possible to recharge the smoke reservoir and make the
part work again. A friend has a can of Blue Smoke (TM) that he bought
long ago when it was available over the counter. Now it is tightly
controlled and only people trained in the repair of electronic devices
are allowed to buy it.
This is more fun than perpetuating the legend of where Naugahide comes
from.

Happy New Year List,
And to the business of building for 2005: I am installing controls at
this time, in the cockpit of my 701, but have still not attached the wings,
rudder, etc to the fuselage, so I cannot hook them up yet. It seems like the
stick has limited throw laterally, moving from vertical only about 3 1/2
inches to one side and about 5 inches to the other, measured at the fork of the
'Y'.
Can any one with a finished product (or close to it) tell me how much
control stick throw is needed side to side to give the necessary flaperon
deflection?
I know I could calculate this, theoretically. But I hope this might
be easier, given all the knowledgeable people out there.
Many thanks,
