Fred,
I used 1/16" dia 7 x 7 wire cable for tail brace wires, same as Bernerd's L
ast Original that was displayed at Brodhead last week. 70 hours and my tail
feathers haven't moved. This cable is available from ACS.

Subject: Pietenpol-List: Tail wires and Turnbuckle
Hey Guys,
I am wondering if it is best or common practice to use 1x19 wire for the
tail
bracing. Thats what I want to use but it only seems to be available in 1/1
6th
which doesnt give me a warm fuzzy feeling, and 1/8th which I think is too b
ig.
Im also worried about wrapping it around the thimble, if it is possible?
Also turn buckle size. Long or short, or does it not matter? Are there an
y
areas where the shorter turnbuckles dont allow for enough adjustment?
Thanks

Well, my proof reading skills are deplorable. In my previous post, the word "not"

of course, it is hot in TX.

Subject: | 1/16th tail brace wires |
I've heard this discussion before.
Lots of guys have used 3/32nd on the tail wires because they are abused in
the turbulent air, and are relatively important. The idea being the thicker
cable will withstand vibration better over time.
Some guys have used 1/16th because the rated strength grossly exceeds the
strength of the wooden structure they support.
Some guys have used the original hard wire per the plans.
My question is this. Has anyone EVER experienced a busted, or busting
1/16th cable on their tail assembly?

Subject: | A simple way to make the straight axle LG |
Just wanted to pass along how I tackled the straight axle LG - It worked relly
well for me. Seeing some photos of upside down fuselages and a lot of jigging
going on really intimidated me. I figured there had to be a way to figure all
this out with some math. As it turned out, my guess was correct.
Check out this article at MATH IS FUN http://www.mathsisfun.com/algebra/trig-finding-angle-right-triangle.html I MUST have been sick the day they taught this in algebra class.
Theory:
Any leg angle (front to back or left to right)are just like a ladder against a
wall. If I have two of the three numbers such as the height of the ladder and
the distance the base is from the wall, I can determine the ladders angle.
The article sample uses a ladder 5 feet tall and 2.5 feet from the wall at the
ladders base ( Opposite = 2.5 and Hypotenuse = 5). I plugged the LG numbers into
Microsoft Excel using the formula =Degrees (ASIN(Opposite / Hypotenuse)) or
more literally =Degrees (ASIN(2.5 / 5)). The correct answer is 30 (degrees)
for the example in the article. A simple scientific calculator works just as well
using Sin-1 (2.5 / 5) = 30 (degrees)
Reality:
I took the numbers from the plans and plugged them into excel to get my 3 primary
angles (one for front legs, one for rear legs and a third for the compound
angle which was the same for every cut). As I explain below there is artistically
a fourth angle.
First attempt: With my angles in hand I went to the miter saw and set my angles
and began to turn a long piece of wood into many short ones - until I got compound
cutting operations under control lost $3.59 and a half hour of my life
gained knowledge. Hints you do not need to lift flip or rotate the board to
make the seconds cut (per strut) just slide it left or right! All cuts have
the compound angle the same and it is never changed.
Second Attempt: My seconds attempt was near perfect! The rear struts were dead
on. I just wanted to make a slight adjustment for the forward strut top cut
to compensate for the slight curvature of the fuse bottom (I added 7 degrees to
the left) and it was spot on!
All in all I had ONE HOUR in the cutting and assembling of the mock up LG not
including attempt #1. A small air nail gun worked great to attach the legs to
my simulated ash blocks. I used a carpenter square (like you might use a plumb
bob) and tape measure to check the finished article to the dimensions on the
plans and they were dead on!
If you are wondering how to determine the length of the struts (hypotenuse), and
the distance from the wall (Opposite) for the landing gear - these numbers are
stated and or determined from the numbers on the LG plans.
Hints: Opposite = ((LG width fuse width) / 2). Do not include the width of the
ash blocks. If you choose to use the TAN-1/ATAN() or COS-1/ACOS() functions,
remember to subtract the height of the ash blocks from the Adjacent (this number
is on the plans).
Tools: Straight axle LG plans ($20), compound miter saw (borrowed $0), carpenters
square, tape measure, pencil, air nail gun + compressor, Microsoft Excel or
a scientific calculator, half a brain
Materials for prototype: One 8 long 2 X pine board (or two if you are a novice
at compound miter cutting!) and some nails /staples for the nail gun ($3.49).
Feel free to email off list me with questions. I might even do a video if enough
ask for me to do so!
Now I just have to figure out how to bend metal fittings.

Nice work on the trig. functions and explanation.
Those trig. calculations can also be useful for figuring wing strut length,
and length changes needed for various dihedral.
It can also be used to figure out what dihedral angles equate to tip height
changes .- I have done this, but don't have the figures in front of me.
(for the standard length wing)- I was impressed with how a small change i
n degree would elevate the tip of the wing quite a bit.
There are many ways to get the job done. I did my wood landing gear with th
e fuselage right side up and no jigging.- All of which is documented on H
INT Video #8 Wood Landing Gear!- (shameless plug,..)

Are the cast covers the only ones with the added lip? If they are and they do weigh
more, then I may not worry about them. I have two sets of the "standard"

I bought the gasket/seal kit from Fresno and I believe the cover gaskets are orange...definitely

I don't recall the tiny details between the different rocker covers and my airplane
isn't handy at the moment (wish it were!)- but here's a photo of mine. They
have the lip that captures the gasket and they are stamped.

Not a bad way to travel per se. Especially if he gets a room with a bed and view.
Good place to read and watch the world go by.
However, You think he is complaining now! Wait until he has dealt with the AMTRAK
schedule. They have a stellar 14% on time rating. It took my daughter 20 hours
to get from OKC to San Antonio (<8hour drive), wait, that is when we drove
up to Austin and picked her up at 3AM. It would still be 3 hours before she
got to San Antonio (< 1.5 hour drive).
Having said all that, He doesn't have a schedule to meet and it is a relaxing way
to travel and he can hobble to the potty when he wants. Take snack food and
flying books and mags. And don't get upset when you get behind schedule.

Subject: | 1/16th tail brace wires |
not and survived it . . . Genedo not archive
From: douweblumberg@earthlink.net
Subject: Pietenpol-List: 1/16th tail brace wires
I=92ve heard this discussion before.
Lots of guys have used 3/32nd on the tail wires
because they are abused in the turbulent air=2C and are relatively importan
t=85
The idea being the thicker cable will withstand vibration better over time.
Some guys have used 1/16th because the rated
strength grossly exceeds the strength of the wooden structure they support
=85
Some guys have used the original hard wire per the plans=85
My question is this. Has anyone EVER experienced a
busted=2C or busting 1/16th cable on their tail assembly?

You guys are never going to believe this.... But we are heading home. The Doctors
kicked him out, said the hospital is for the sick and broken, and he needed
to get on down the road. I'll spare you the details, but with alot of logistical
wrangling, and help from local friends we were able to get moved to a hotel
for the night, and we will by flying home tomorrow.
(AM Trak was a bust, couldnt get a seat until 10 August)
Thank you for your all of your prayers and support, i truly believe that all of
the positive thoughts and prayers made the difference.

God wasn't ready for Kevin yet and now the hospital turns him away too. I guess
we get to keep him around for awhile ;o) This is good news indeed. I am convinced
that rapid healing has a good deal to do with one's state of mind, determination
to move on, and refusal to throw pity parties. Somebody remind me
of that when I'm hurting and just want some sympathy and stroking ;o)
Safe journey back home...

Subject: | Re: 1/16th tail brace wires |
Busted a 1/16" tail brace wire and survived it. Didn't even know it was busted
till back on the ground. Now flying with stainless 1/16" wires back there because
I'm convinced it was corrosion and the resultant fretting that caused it
to let go. Those wires, and all the tail surfaces, really do vibrate a lot in
flight. There were NO frayed wires in any of the cables, as demonstrated by
the bare-finger inspection time and again, with no loss of blood.
Before the naysayers jump in, I'll acknowledge that stainless is not as good as
plain steel in strength, but it is better in corrosion resistance and I still
have the old tail brace wires if anyone doubts that corrosion doesn't take its
toll on things on the back end of the airplane and wants to see them. It's
my fault... I never bother to wash the airplane so it does build up debris back
there from time to time, but then again it gets some oil mist too. Okay, so
the oil mist attracts fine dust, which is an abrasive and tends to aggravate
the fretting. My bad, but I'd rather fly the airplane than wash and polish it.
If you don't want to worry about the tail brace wires, use 3/32" cable or the old-timey
smooth wire with ferrules. I'll bet if you used 3/32" with no turnbuckles
(twist the wire to add tension) you'd be as light as if you used 1/16" with
turnbuckles, or lighter. And you'd save money on turnbuckles. There doesn't
need to be a lot of tension on the wires, it just needs to form a fairly well
braced and evenly balanced assembly.
Let's see: at last count I had used up 4-1/2 of my allotted 9 lives (I only count
the broken tail brace wire as loss of 1/2 life). The object of the game is
to end up with at least one life in reserve at the end, or 45 minutes of fuel.
Or, wait... isn't the object to use up that last remaining life on a beautiful
springtime flight, low and slow, with the airplane trimmed up for hands-off
flight, perfect temperature, pull the "SMOKE" knob, and then yell "YEEEEEAAAAHHHOOOOO!!!"
as your ticker decides to head for the barn??? There are worse
ways to go.

Anyone care to recommend an air compressor for the shop? My 30 year old Craftsman
professional gave up the ghost. Can not locate a new motor with a pivot style
mount. Parts are no longer available from Sears. Yes, I want continuous
duty for drill, sander, impact tools, etc. Any suggestions?
