Brief Description: OAT and remote compass; flap attach bearing
|

Did several little projects tonight:
1. A while back, I inadvertently got ahead of things and pulled the Dynon compass cable through the left wing conduit. Since the large DB-25 connector on this harness cannot be easily passed through the side of the fuselage, I pulled it out, replacing it with a string so I can pull it back the other direction when the time comes for its final installation.
2. I cut the OAT cable that comes out of the end of the the tip rib to a reasonable length for it to attach to the Dynon compass module. Added an Adel clamp near where the cable emerges.
3. Marked and drilled out four attach holes on the Dynon remote compass mounting shelf for the compass, then test-fit the hardware that will attach it. The AN3 bolts, washers, and nyloc nut are all non-ferrous (aluminum, in this case), as called for in the Dynon manual.
4. I am thinking about scrapping Van's standard rod-end studded bearings that are used to attach the flap rods to the flaps. They do not extend far enough inboard, as I found last night. So I am considering doing something like photo #3 below. The gap between the second and third washer will be filled by a substantial aluminum spacer. I may have to machine these, unless McMaster-Carr has something suitable. These assemblies would move the rod end out further from the flap, which is exactly what I need. Plus, they might be stronger than the stock installation.
