Just find versions that have the flange welded onto the bend. I needed a straight shot off the firewall for mine, so I cut it short enough that I just had a short stub left for clamping the fire sleeve. Ebay has had smaller (~1") stainless flanged stubs in the past, but I can't find the link now.

Un impeachable logic: George Carlin asked, "If black boxes survive crashes, why don't they make the whole airplane out of that stuff?" ________________________________ Message 4 _____________________________________ Time: 09:02:42 PM PST US Subject: AeroElectric-List: Clearance Delivery Diode Leakage From: "MFleming" The wiring has begun for my RV-7. I've decided to use fuse blocks for circuit protection. The architecture will utilize a clearance delivery (CD) buss. The CD buss has a diode installed per Z101B. When applying DC voltage to the CD bus and measuring the voltage at the main buss, there is a 350 to 390 mv reading. Is that enough to worry about or do I have a bad diode? This is the B&C Essential Bus Diode w/ 8 watt heatsink PN-221-200. Heres a photo of the fuse blocks while being tested for leakage. You may be able to make out the 351.8 mv leakage. http://myplace.frontier.com/~tokosha/avionics/test_diode.jpg -------- Michael Fleming Read this topic online here: http://forums.matronics.com/viewtopic.php?p=499896#499896 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message aeroelectric-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/AeroElectric-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/aeroelectric-list Browse Digests http://www.matronics.com/digest/aeroelectric-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
