Happy 2016!

Man, it feels like I haven't posted an update since LAST YEAR. <groan>

Well, we've made some forward progress, but not really anything too terribly note- or photo-worthy. Additionally, I've been working on a side-project in the garage, swapping a transmission out of my old '77 Impala for one that has an overdrive in it (TH200 for a TH200-4R for all you gearheads). It's kind of tough doing a tranny swap working around all the airplane parts that are in the way, but hey that's life I suppose. It's almost done now, just have to figure out the necessary modifications to the crossmember. Anyway, as for work on the plane itself, the doors and cabin cover have come back off, and this allowed us to tie off a number of loose ends that remained on the fuselage itself. Namely:

  • Completed securing, attaching, and tightening all of the fuel system components. Now the only part of the fuel system that remains are the connections to/from the tanks and of course FWF.
  • Completed assembly of the control system, including measuring the pushrod lengths for the elevator controls and safety-wiring the appropriate rod ends. Fabricated a small "washer joust" out of 0.032" aluminum, drilling a 7/16" hole at the end, and then sanding the end off until only half the hole remains. This way you can push washers in between the different control system components as necessary without fumbling around with your hands.
  • Attached nutplates along the mid fuse longerons by the rear seat area. This was a leftover task from the "access covers" section because I had experienced significant difficulty setting rivets in this area. They are at kind of a funny angle and I didn't have anything that seemed to work to buck these. Ultimately, I was able to succeed using a swivel flush set and an array of different bucking bars.
  • Swapped out all the hardware attaching the rear seat belt anchors in the tailcone with stainless bolts and custom stainless cables. This is a recommended procedure for any ferrous metal located within about 3 feet of the magnetometer, per Garmin's instructions. I had previously attempted to do this, but had a terrible experience with galling and broke a number of bolts. I was able to succeed this time by lubricating the bolts first.
  • Installed a few of the access covers and began test-fitting some of the Aerosport interior panels that I have. It's cool to get a glimpse of what the interior is going to look like!
So basically, the fuselage is getting pretty darn close to "done" status. Items still on the "to-do" list include rudder pedals (still holding out for some Control Approach pedals... it's not the funnest waiting game in the world but I figure as long as I have other stuff to work on we'll keep dragging it out) and dimpling/riveting the upper forward fuselage, which I'm going to lump in with work on the panel. Hopefully, we'll be able to get started on the panel sometime soon too! Still need to make it up to the Minneapolis area to pick up my avionics from Stein. Of course we can have them ship all the stuff but I thought it would be fun to get up there in person and pick it up (cost would be about the same or even a little cheaper than shipping with insurance). It seems like the weather has been conspiring against us making a flight up there for literally weeks now! We may have to just break down and drive up there. Maybe as a test drive in the Impala once the tranny swap is done... hmmmm.

Other than that, the work that remains now is to finish up the cabin cover, which mostly involves fabricating the overhead console, and get it final-installed on the fuselage. After that happens, we can finish with the doors, and then we can proceed with the rest of the finish kit items. Stay tuned for all that!
