Brief Description:  Install avionics cooling fan & fabicate mounting b

I spent a couple days figuring out where to mount the Ameri-King AK-950-F5 five-port avionics cooling fan and finally came up with a good location in the avionics bay. A big part of the consideration was how I could ever get the fan out of the avionics bay if I ever needed to repair or replace it. My solution was to mount bolts that were "reverse" safety-wired so I wouldn't have to use a wrench to hold the bolts while I removed the nuts. The fan will provide forced cooling air to the Garmin 430W, GTN327 Transponder, the Grand Rapids HX EFIS, the Dynon EFIS, and the second ICOM COM radio. There are 6 bolts that mount the fan to the side and on the firewall. I fabricated an angle bracket to mount the back of the fan unit to the firewall, riveting the bracket from a flange on the cooling fan. The fan already had a side-mounted bracket so I built a reinforcing bracket mount and bolted to one of the ribs in the avionics shelf. I safety-wired all these bolts and used castle-nuts with cotter pins on the sides and back. Its not optimal for removal, but it can be done if I ever have to. Next I'll mount the 5 hoses to the appropriate avionics and compete the wiring to a dash mounted switch. I was originally going to build a temperature sensitive switch so the fan would come on automatically when the temperature got to a certain level, but I would never know when the switch (or fan) failed and I wouldn't be able to shut the fan down if I had an electical failure which required conserving all essential electical power...besides I'm already way over the edge for building stuff I don't really need. I need to focus on getting this project done so I can actually enjoy flying.
