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!

From: "Jeffrey J Paris" Hi Listers, I was doing my annual condition inspection on the Zenith CH601XL/ JABIRU 3300 this past weekend. (182 total hours engine and airframe) While I was putting one of the valve covers back on the engine I noticed a little bit of an aluminium burr in one of the bolt holes for the 5/8 X 1/4 UNC Socket Head Cap Screws Jab # PH72624. I ended up pulling quite a long "curly-Q" piece of the burr out of the hole. For the most part it is stripped. With that in mind, What would be the best way to repair the stripped hole? I have been looking at18-8 Stainless Steel Helical Inserts to make the repair. Or do you re-tap the hole to the next larger size bolt? Any other Ideas? Can't seem to find anything in any of the "FAA Standard Practices" books on what to do. Let us know at your earliest convenience. Thank you for your time and consideration.

From: "jetboy" Jeff, I would use Helicoil or similar inserts. The ones I used for an alloy engine head came with the drill, tap and inserting tool. I'm contemplating having to do this for the spark plug threads one day - surprised they are not already fitted because my Continental 0-200 (SA) heads had them from new and the NGK plugs seem to mess the threads on the way out as if they have too much thread in the cyl.
