Hello all Piet enthusiasts
I want to encourage anyone who is "stuck" on/in their Piet project facing a
"mountain" that has you stuck to either reach out to a fellow builder, or
just face it head on and push through it. I have just faced another
"mountain" and I have overcome it. If I had not, my project would have begun
to collect dust. This past weekend I began installing my wood straight axle
LG fittings onto the fuselage and it is going quite well. A lot of
trepidation about drilling the bolt holes "true and straight" was my main
concern followed by cutting out "slots" for the inner fittings. I trusted
in my fabricated drill guide and I went for it. After seeing the first pair
of fitting with bolts going through them I was very happy. I'm very excited
now about my progress on my Piet. Facing this challenge and completing the
turtle deck has given me the even more confidence that I will complete it
and continue to have a blast doing so.
If your "mountain" is engine related, no matter what engine it is, Corvair
College is a great place to go. Even as a spectator you will learn a lot
about building a flight engine, and it might be the catalyst that gets you
over the mountain and allow you to look back and see it was just a mole hill
- as I did on several occasions.

Now an editorial:
It looks like perhaps EAA is getting the message that many of us in the Piet
community feel like EAA is not looking out for the interests of the "grass
roots" home builder. The new Experimenter monthly digital magazine is very
nice, but is in danger of becoming its big brother "Sport Aviation". For
those of you looking for a "grass roots" group focused on building airplanes
"a hundred dollars at a time" consider also joining the newly re-started
Sport Aviation Association. It's back and led by Ed and Val Fisher, along
with several others in supporting roles. Ed and Val will be at the Corvair
College in Barnwell in a couple of weeks. Ed Fisher along with Editor Jeff
Lange have put out a first issue and it is the same flavor as is BPAN -
printed, mailed, fun to read. Membership is donation based.
They have a website:

Subject: | P-Lead, Wire, Grounding, AM4 Mags |
Crew, I am ready to make up my P-leads for my Eisemann mags and am not clea
r on how to do so.- I would like to use sheilded, (braid) wires but am no
t sure how to make the connections at the switch nor at the mag. How/where
do I ground the braid? I assume I need to run grounding wires from the engi
ne, to the mount and also to the mag P-lead braid...true?
If anyone has these mags and can take a picture of how the connection is ma
de at the mag, that is about all I need...I believe.
Thanks.

Yesterday I was giving a friend some tips on replacing p-leads on a
Grumman. Here is some of the stuff I sent him:
I think 18awg shielded
wire is
correct:

informative aircraft mainteance web site in the
world:

The mag
should have a screw terminal where you'll connect the ground braid (and
another insulated terminal for the p-lead or center conductor). It is
also connected to the mag switch at the other end (to kill the motor). I
think the mags are grounded through the engine case so no ground is
needed to the case. The case should have a braided (flexible) ground
strap to the engine mount I believe. It probably isn't that important
for a wood Piet...in metal aircraft you are bonding the engine to the
airframe with that strap. Doesn't do much good with a wood fuselage.
Be sure to brace/secure your wires every few inches or they will break
in short order due to vibration!
Good luck!

It looks as though mykitplane is gone. I've gotten no response from the administrator
and the sight (and all my past info) is lost. Time to move on.
I want to post pictures and share with friends my build log. I believe kit log
pro is the way to go for me. I however have a mac and will need to install a
windows operating system for this app to work. Should I buy windows 7 or wait
for windows 8? I thought maybe some of you apple guys or computer people might
have some words of wisdom for me before I make the plunge.
Thanks

Subject: | Re: P-Lead, Wire, Grounding, AM4 Mags |
The ignition wiring on Scout is done exactly as Steve has described. Note, however,
that this goes against what Tony Bingelis says in one of his books, at least
the part about grounding the braid on the P-lead wire from the magneto to
the ignition switch. I don't have my books here in front of me (I know, I know,
Mikee- I should always have them with me ;o), but I believe Bingelis says
that the braid should only be grounded at one end, not both. Not sure why that
would be, though. And since the magnetos have a lug for landing the ground
braid and the ignition switch does too (or at least a lug for landing the ground
wire that shorts the P-lead to ground), I grounded both ends of the shielded
wire braid.
I am ducking for cover, as I see electrons beginning to fly from the electrical
system gurus even now.

John,
I am using a simple Wordpress blog. It is pretty simple to set up and
edit. It is a different option and is operating system independent.
You do have to get web hosting though. Mine is at www.bearhawklsa14.com

I don't have Tony's book, but what he means is that the braid should
not be grounded to the airframe at both ends. What you are doing is
using the braid as your grounding conductor for the mag which means the
braid is not connected to ground at the switch end when the engine is
operating, so there is no chance for noise issues if you had parallel
ground paths. So essentially you comply with what Tony
recommends...that is also how my plane is wired.
A shielding conductor (the braid) is typically only grounded at one end
I believe to avoid ground loops & noise issues due to having multiple
grounding paths.
Clear as mud? :)

Hi John,
It doesn't particularly matter whether you go with 7 or 8 for your
purposes; Kitlog will run the same on both. Windows 8 has a new default UI,
called "Modern UI" (formerly Metro), which is where Microsoft wants to go
for the foreseeable future. See the screenshots in this gallery:
http://www.theverge.com/2012/10/23/3542270/windows-8-review-screenshots#3885907
However, only apps written for Modern UI will run there. In order to
provide compatibility with all existing Windows applications, there is also
a Windows 7 style desktop. In your case you would install Kitlog, and it
would add a Kitlog "tile" to that default Metro screen. When you click on
it it would open Kitlog on the Windows 7 style desktop, and you would use
it just like normal.
Amazon and Newegg list the System Builder DVDs for Windows 8 at $99, and
Windows 7 Home Premium at $91-$99, so about the same cost. As it sounds
like you are primarily going to use Windows for Kitlog, you shouldn't need
anything higher than basic 8 or 7 Home Premium; Pro versions provide more
features for business environments, such as joining to a domain,
etc. Windows 8 is the Windows future, whether we like it or not. It's been
tested to boot up/shut down faster, and perform somewhat faster in general
than 7 on the same hardware. If you're a longtime Mac user that doesn't
mess with Windows much, you actually might have a lower learning
curve.....you'll have less to "unlearn".
There is a free to download/use Windows 8 Release Preview available from
Microsoft; this is Windows 8 in more or less final form, and will work
until 01/15/13. You could install that on your Mac via Boot Camp (or with
Parallels/VMWare if you use that software), and grab the trial version of
Kitlog to give the combo a test run to see if you think it will work for
you. You can grab the ISOs for Windows here:
http://windows.microsoft.com/en-US/windows-8/download

The last time I posted I told you I'd keep you posted on Kevin's progress. As
most of you know he has recovered at an amazing rate.
Friday Kevin was cleared to fly by the Army flight Surgeon. I'm not sure I can
keep his feet on the ground, he is practically floating.
Kevin recently wrote a short article featured on the Flycorair.net page, you can
check it out at your leisure here
http://flycorvair.net/2012/10/25/guest-writer-pietenpol-builderflyer-kevin-purtee/
Veterans day weekend we are heading to Barnwell, SC to attend CC24. WW was able
to retrieve the engine from FBG in order to assess the damage to the engine...
which remarkably is in good shape, but in need of some TLC. We hope to reassemble
the torn down engine and run it on the test stand at CC24.... it should
be quite the spectacle ... we hope to see lots of you there.

Clear as mud. I'll describe my setup in a little more detail and let's see what
I have. Let's use the (stainless steel sheet) firewall as the starting point.
Firewall forward, I have the braid shielded P-leads from a screw terminal
block on the firewall, with the braid shields landed to a common "grounding" lug
on the firewall. I put "grounding" in quotes because what the heck is it really
grounded to? The metal firewall is really just the point of zero voltage
reference, I guess you'd say.
The leads continue forward to the magnetos, where I have the shields landed on
the magneto ground lugs at that end. I have a flat braided grounding strap from
the engine block back to the "grounding" lug on the firewall, so it sounds
to me like there are parallel ground paths right there. It didn't seem to me
that the engine mount points (through rubber donuts) were a solid metallic path
between engine block, engine mount, and firewall so I added the flexible braided
grounding strap.
>From the screw terminal block through the firewall aft to the ignition switch,
I have the braid shields of the P-leads landed on my "grounding" lug on the firewall
at one end and on the ground terminal of the ignition switch, but other
than that there aren't any continuous metallic grounding paths from the firewall
aft.
NOW clear as thick mud? For what it's worth, using a handheld COM radio has demonstrated
that there is no noticeable ignition noise from this setup.

Kit Log Pro is excellent, and it does the things you are wanting, and then some.
In addition, it is developed and maintained by Matt Dralle, who is also the
administrator of Matronics.
I really like the program and would recommend it first to anyone looking for builder's
log software.
