I haven't been doing separate entries lately. There's only so many times you can say "pulled more wires" without getting depressed. However, I've got to say that the end is (hopefully) in sight. Went to Tucson last week to get kid 2 graduated from UofA. A good time was had by all :) Was planning to use a fuse link from the downstream side of the pitot switch to a discreet input on the GAD27 for a cool "pitot heat on" CAS message on the PFD. The smallest wire I had on hand was 22, so I used that for a link into an 18awg that was intended to go to the GAD, but realized today that there's no way I can cram a wire that big (18awg) into a D-sub pin, so I'm going to have to re-think this. Discovered a cut in the insulation on a power wire I had just installed. It was right off the roll and I'm 90% certain I didn't cut it installing it. I got it in a "by the foot" order from B&C where they just roll it off a big spool and send you however much you want, and I'm pretty sure it was that way out of the bag. R&R and then moved on. Started running coax. The goal is to pull all the wiring to the back of the plane, then close up the floors so I can sit in it. I'm at the point that it would be easier to do some of the cabin side stuff sitting in the plane instead of leaning over so much. I took a break from wiring today and installed the certified GPS antenna. Lot's of guys have had success putting this on a tray under the cowl, but since this is a certified unit for a IFR plane, I'm staying on the reservation with this one. Back deck, aft of the canopy, following all of garmin's instructions as much as the physically small size of the RV will allow. Garmin has a bunch of limitations on antenna placement. For example, they say this antenna should be 2' from a comm antenna and 3 inches from a window. You may recall that I elected to put both com antenna on the bottom of the plane, but if that doesn't work out and I end up having to move one to the top, I don't want the placement of the GPS antenna to be a problem, so I kept it as fat forward on the tailcone as I thought I could get away with. Due to the way the canopy pops up on the track as it moves aft, it will clear the antenna no problem. I verified that by making an antenna shape out of foam and simulating the canopy skirt with a ruler taped to the trailing edge of the plexiglass. It turns out that the limiting factor is the canopy bow. If it clears that, it will clear the skirt as well. Based on all these considerations, I located the leading edge of the antenna 4" aft of the rivet line for the baggage bulkhead frame. This is in a pretty beefy area, with a rib and internal gusset on one side and a J channel on the other, so I toyed with the idea of skipping the doubler, but the skin back there is only .025, so I erred on the side of caution and fabricated. a doubler out of .040 scrap. Spent most of the morning fabricating the doubler, laying out a rivet pattern that made sense, dimpling, and then installing it. I was able to reach both sides by myself, and I got it installed no problem. I'm also planning to have a remote start button on the stick, so I found a location on the sub panel that made sense (left side of IBBS battery) and installed nut plates and mounted a relay for that system. It's getting really crowded behind the panel!
