  Sat Aug 11 21:26:56 2007 - I've yet to drill/c-sink it to the firewall and bend the ear for the adel clamp. A couple of notes: The firewall was dimpled and the bracket countersunk; The big bracket was made from .040" 2024-T3 aluminum sheet; there is also a .060" 2024-T4 directly under the valve to allow countersinking for the ANI509 screws; I'm going to attach a "B" nut to the Matco's arm (ACS #05-16245) - but until that gets in, I'm not going to bend the "ear". On a lighter note, I managed to work with the SS firewall and managed not to cut myself. ;)  Sat Aug 11 19:14:46 2007 - The Matco Parking Brake has been an interesting learning experience. After looking at other folks designs/solutions, I settled on this on (which I borrowed from Dave Parsons). I had purchased TurboCAD a couple of months ago with the intent of doing my electrical system in it. I figured that drawing this attachment plate would be a good exercise given that I really haven't ever used CAD before. Some design criteria: I had considered relocating the Matco valve but I wanted to reuse the existing holes from the original brake line bracket; Several builders had commented that the firewall flexes to much when actuating the brake valve so I needed some extra rigidity; I needed to keep the valve as far forward as possible to prevent any interference with the rudder pedals; and I wanted to maintain a smooth firewall for any possible future attachments.   Sat Aug 4 20:56:29 2007 - Riveted on the nutplates to the Andair valve. The Andair valves are very modular and it helps to remove the flare fittings in order to rivet on the nutplates. It took some effort to get them to come off the first time. The valve comes with screws that are to be peened but I'll wait till everything is together in the fuel valve area. The AN fitting (sorry, no AN part number - Van's description is "F SWIVEL TEE ANDAIR/FI FITTING") is used to allow fuel to recirculate from the AFP pump.   Wed Jul 25 19:24:54 2007 - Santa Claus showed up today (aka the UPS Dude). I opted to substitute Van's brakes for a set made by Grove Aircraft Co.. I also requested that Viton o-rings be substituted which they did for free. Viton has a temperature range in the neighborhood of -40˚F to +450˚F. Nitrile (aka Buna N - which is what is normally used) o-rings are generally good for -40˚F to +212˚F.  Wed Jul 25 19:22:57 2007 - Failed attempts and lot's of frustration trying to fit the tubing around the rudder cable and pieces of angle. I used short pieces of scrap to practice on. Hmmm..maybe I should arrange them into some kind of sculpture.
