| Subject: | Re: Grounding Of Fuel Senders |
Connect a ground lead to it the sender, and run a return anyway. It
might leave you scratching your head why, if the the thing is grounded
anyway?
It's a simple, safe practice thing to do. Which if you follow religiously
will leave you with radios that are crystal clear, and an intercom
with no noise, etc.
The best way to avoid, electrical/avionics trouble in a plane, is simply
pretend the entire airframe is made of plastic, and treat every electrical
device accordingly.

Jeff

You should have separate ground leads for all of you avionics and
other circuits in the cabin, that is where ground loops are most
likely to cause problems. Grounding the lights and fuel senders in the
wings to the airframe shouldn't cause any issues.

| Subject: | Attention Corvair Builders |
To Whom it may concern:
We have updated our website, www.magnificentmachine.com, with some technical articles that are aimed at answering the most common questions relating to our products and the Corvair.
Also these articles address some of the more common engine issues and some of the
ways in which we address them.
This section is called Tech Talk and is where we will post all of our Products
Testing Data.
The articles are written by "Uncle Mike" because he is a far better writer than
I am and his engine building experience goes far back to the days of Flat head
engines and probably back to the days of wooden spokes though he won't admit
it. Smile
The First Forged 4340 crankshaft sample is now in an engine case with a cam shaft
and will be running before too long.
This engine will be equipped with our entirely NEW rotating assembly as well as
the rest of our newest products.
The first set of all aluminum Nikasil Cylinders will be installed and tested on
this engine as well.
We will have this engine at the upcoming Corvair College #13 being held In Livermore,
CA.
For further details of the Corvair College #13 event see
www.flycorvair.com or

Thank you,

| Subject: | Simple rivet test/unzip |
This evening ...
I took two pieces of .025 500mm long, riveted them with A4's at 40mm
pitch. clamped the end of one in a vice, and grabbed the other piece
with a pair of vice grips. One sharp tug unzipped the entire strip with
very little effort .... Every single rivet head popped right off like butter.
Riveted with the zenith hand riveter and zenith concave head.
Food for thought.
Regards,
Jeff

"riveted them with A4's at 40mm ... One sharp tug unzipped the entire strip...

add the new "triangle and house aileron gussets," use A5 SS rivets on the gussets
and try that again...

I designed my aileron gussets in January, they were/are external, 6061-T6 and .060
w/A5 SS rivets.
They were my response to the unzipping of 601 ailerons in light of an examination
of in-flight video by myself, my IA and my test pilot. The inboard one looks
like a triangle, the next outboard, like a house.
Zenith has incorporated similar ones on the 650, I am told they are internal and
thinner. I know some builders have ordered them and installed them on their
601s. Zenith has their own reasons for the design change.

Thanks Sabrina,
Do you think the rest of us should consider adding these gussets? Do
they apply equally to hingeless or hinge type ailerons?
I still can't quite imagine exactly what these gussets do or where
they go. Which rivets on the aileron can unzip? The Hinge area? On the ribs?
Thanks,
Paul

I would rely upon Zenith and install their gussets per their specifications. CH
knows what he is doing. If anyone has the new plans, maybe they could describe
the 650 versions. The AMD safety alert seems to talk to this issue:
