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: http://www.matronics.com/MattDralle-ListComputerCenter.jpg 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! http://www.matronics.com/contribution Or, by dropping a personal check in the mail to: Matronics / Matt Dralle PO Box 347 Livermore CA 94551-0347 USA (Please include your email address on the check!) There are some great gifts available with qualifying Contribution levels too! Thank you!

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.

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. Jack B.

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.
