Bleed Brakes / ELT / Fuel Tank

Another day and tackling several different aspects of the build, hoping to get it ready to move to the hangar soon.

I started out with the help of N to get the brakes bleed. After doing a little research online and EAA videos I chose to bleed the brakes using an oil can and hand pumping the fluid from the bottom up. This worked out fairly well. It took a little work getting air bubbles to completely resolve through the cylinders, but it was accomplished. Overall it worked out better than I imagined. And no visible leaks found so far.

I then installed the batteries on the ELT remote and audio alert. The remote was then installed in the panel.

The canopy light was installed. The fuel tank was installed along the the neck. The plans called for fuel sealant to be placed between the neck and the turtle skin, so fuel sealant was mixed and placed prior to setting the screw of the fuel neck.

ELT, Panel Paint, wiring

My center panel arrived today so first thing was  to mark and cut the location for the GMC 307 autopilot. Holes were countersunk as per plans. The map box was then riveted to the right panel. The panels were then primed and painted with Rustoleum Hammered Black.

Then work continued with the ELT. The instructions required soldering of some wires to the connector for the ELT. Not being experience in this I had to revert to youtube for a bit of instruction. After a little trial and error I was successful in getting 4 wires soldered to the small pins in the connector. One wire was placed for testing in future if required. I also attached a ground wire and bolted it to the ELT bracket. The ELT and antenna was then installed.

Having read through some of the following sections I decided now would be a good time to place nutplates for the voltage regulator. There is the option of placing bolts and nuts or nutplates. The nutplates will allow for easier replacement in the future if needed.

I then finished up with the wiring in the tailcone. The following were completed: Aft pitot line, Static line, OAT, CPC connector magnetometer, D-sub connection, connections to ADAHRS.

ELT

Started on the ELT section today. It called for installing nutplates. Since there were rivets already there they had to be drilled. out. Holes were made for the rivets for the nutplates and then the nutplates were installed.  I painted the antenna bracket.  Also installed the ELT bracket and holder. Vans instructions called for following the instructions with the ELT which can be a little confusing. One part calls for soldering, so I will have to figure that out another day.
