| Subject: | [Please Read] What are "The Lists" and Who's This Matt Dralle? |
Dear Listers,
Who is Matt Dralle and what exactly are these Lists? Well, I've been working in
the information technology industry for nearly 25 years primarily in computer
networking design and implementation. I have also done extensive work in web
development and CGI design during that time, along with some embedded system
development as well.
I started the Matronics Email Lists back in 1990 with about 30 fellow RV builders
from around the world. Since that time, I have added 63 other kinds of aircraft
related Lists to the line up and numerous other List related services such
as the Forums, Wiki, Archives and Search Engine just to name a few.
For flexibility and reliability, I have chosen to run all of my own servers here
locally. Other List-related systems include a 1 Gigabit, fully switched network
infrastructure, a commercial-grade Netscreen firewall, a Barracuda spam filter,
a local T1 Internet router, and a commercial-grade business T1 Internet
connection with full static addressing.
The computer servers found here include a quad-processor Xeon Linux server for
List web services, a dual-processor Xeon Linux system dedicated to the email processing
List functions, and another P4 Linux system serving as a remote storage
disk farm for the archives, databases, and for an on-line hard drive-based
backup system with 3.2 Terra Bytes of storage! This entire system is protected
by three large, commercial-grade uninterrupted power supply (UPS) systems that
assure the Lists are available even during a local power outage! Speaking
of power, imagine how much electricity it takes to run all of these systems. One
month last Summer, I had a staggering $1368 bill for electricity alone!
I recently upgraded all of the computer racking infrastructure including new power
feeds and dedicated air conditioning for the room that serves as the Computer
Center for the Matronics Email Lists. Last year I added another rack to
house the MONSTER quad-processor web system that didn't quite fit into the first
rack! Here's a composite photo of the List Computer Center before the addition
of the second rack:

As you can see, I take running these Lists very seriously and I am dedicated to
providing an always-on, 24x7x365 experience for each and every Lister.
But building and running this system isn't cheap. As I've stated before, I don't
support any of these systems with commercial advertising on the Lists. It is
supported 100% through List member Contributions! That means you... and you...
and YOU!
To that end, I hold a List Fund Raiser each November and ask that members make
a small Contribution to support the continued operation and upgrade of this ever-expanding
system. Its solely YOUR Contributions that keeps it running!
Won't you please take a moment to make a Contribution to support these Lists!

A little one inch hole won't make a significant change in the overall
strength of a large fabric panel. In the case of fabric on a non
stressed
area like the cage it would be totally irrelevant.

Just my personal observations but I don't do any of this stuff and my
fabric holds great. I have had to replace large portions of the fabric
on my cage where I welded on the new VW mount and other patches around
the cage where the fabric literally gets pounded by the prop and nothing
works loose.
I merely wipe the area I will be sticking new fabric to with MEK. Stick
it with Poly Tack iron it tight and cover with the Poly Fiber process. I
don't even pinking shear anything. On my ten year old airplane the only
fabric that has worked loose is that fabric that was pinked.
I know the certified process of covering fabric airplane says all edges
must be pinked but is it better that way? I know if I were to lift a
glued anything I start at a corner. Try it yourself. Stick a piece of
tape to something and then remove it. Where is easiest to start. Do you
start in the middle of a smooth side or at a corner?
Just getting a discussion going.

Bob and others,
Strength of the patch has to do with fabric overlap. In most cases this is
not a problem. Strength is getting confused with tension of the patch and
the surrounding fabric. This is why Richard's method is good, in that, one
can reestablish uniform fabric tension in the patch and the surrounding
fabric by shrinking the patch.
A teflon coated cookie sheet might be an improvement over the frying pan.

Here's a similar way:
Clean up the hole with an exacto knife. I usually will make it square. Cut a piece
of fabric with 1" overlap and round the corners. Use lacquer thinner to clean
around the hole. Place the patch over the hole and brush Polybrush outward
from the hole. Make it as smooth as possible. Let dry 24 hours. Take a small
monokote iron at low heat to shrink it slightly. Using too much heat will make
the sides of the patch bow inwards. Use two more more coats and then paint with
Polytone. If done right, the patch will be difficult to see.
I have used Polybrush instead of Polytak for large patches too. It makes for a
nicer patch.
