So this entry represents 3-4 shorter sessions over the last few days. I realize 24 hours is a bunch for something so simple, but I'm including a realistic estimate of research hours, as well as time spent going to two different local hobby shops looking for an appropriate linkage setup for the POS-12 sensor. There was some rework of the mounting bracket to allow for a more protected wire run as well. Google research revealed several people had used model airplane parts to fabricate a pushrod to go between the flap center weldment arm to the POS-12 sensor. The first local shop I went to was in the process of packing up for a move to a different location and didn't have anything that would seem to work for me, so ended up going to a different smaller store and he had exactly what I was looking for. He also asked me what it was going in and wasn't surprised at all when I told him because I wasn't the first person to source model airplane parts from him for a "full scale" Several old threads on vans indicated most folks went one of two ways on this; Either put the POS-12 high up on the center pillar with about a 10" pushrod to minimize the angle change, or mount it lower down on a bracket that holds it at about a 30* angle to the vertical. I was inclined to go with option 2, but the exact angle this needs to be mounted on is dependent on the length of the pushrod. I wanted to get the sensor low enough that it would be relatively easy to remove either it or the drive motor without one interfering with the other, so that meant a mounting location that utilized about a 6" pushrod and approx a 20* mounting angle. The angle bracket I fabricated has a short leg of about 1/2" and a long leg about 2". I just adjusted the angle of the longer leg until I got the POS-12 sensor arm planar with everything else and then match drilled it. Like I said, it ended up being about 20* in my case. Everything was aligned and traveling smoothly, but I was having a heck of a time figuring out how to route the wire bundles up through there without them potentially chafing on the edge of the bracket or being in danger from the screws for the side covers. After trying several different solutions, I ended up enlarging the hole in the aft center floor panel where it's under the vertical center post and running wiring up through there from the center tunnel. I also remade the POS-12 bracket in such a way that I could put a couple of snap bushings in it and run the wires under it. The bushings are offset in such a way that the wires are out of reach of all nut plates etc. Wire bundles run, pushrod on, motor wired up, pushrod safetied, everything torqued, secured ops checked, and otherwise wrapped up. Also wrapped the wire bundles under teh fuel pump pallet with snakeskin that came from spruce while I was out of town last weekend. Sweet!
