On the RV-7, it&#8217;s the space behind the baggage compartment going all the way down the tailcone to the 3rd-to-last bulkhead.  Working down there really does make wish such things as aircraft elves existed.   Unfortunately, they don&#8217;t, so I had to crawl down the Jeffries Tube to drill holes in bulkheads for wiring grommets, carrying a big cordless drill, a bit for the pilot hole, a bit for the grommets, a deburring tool, and the grommets themselves.  I was able to get the grommets in and start the wiring run for the strobe cable and tail light power wire.   It&#8217;s a slow process, and being mildly claustrophobic and crammed into a metal tube reminded me of my recent unsettling, yet action-packed U-boat dreams.  I&#8217;m going to be spending a lot of time down there.   I also have to drill grommet holes for the ELT coaxial cable and set up the wire stays for everything.    I&#8217;m trying to avoid drilling more holes in the longerons and j-stringers, but I do have some adhesive-backed cable tie holders that will need to be placed.<\/p>\n<p>As an aside, I finished the lower empennage fairing.    These two stupid pieces of metal are supposed to have a rubber seal on them, but there&#8217;s no way that&#8217;s going to fit.   Also, there&#8217;s no point in making these things removable, so I riveted them on.  So now I have a 1\/16 to 1\/32 gap along the horizontal stabilizer at the root.   So I lose a knot.   Big deal.   If it concerns me later, I&#8217;ll create a proper fiberglass lower fairing.  Speaking of fiberglass, I got the empennage tips riveted on.   they&#8217;ll need a coat of primer\/paint, but they&#8217;re done.<\/p>\n<p>Also, yesterday I got a call from Tim at Tim&#8217;s aircraft.   My spam filter de-rezzed his pdf of the engine repair estimate, but I got a new one from him.   Nearly eleven grand.   Ouch.   But now I have nitrided steel cylinders instead of that godawful cermichrome and it&#8217;s going back together as soon as the magnetos come back from the specialty shop.   I just hope he doesn&#8217;t flinch at installing the AFP fuel injection system.   But what that means, brothers and sisters, is that I&#8217;ll probably be hanging the engine in the not too distant future.  At this point it&#8217;s now time to get down and dirty with the remaining amounts of money and see if there&#8217;s enough for avionics, remaining FWF, interior package, taxes, training, and hangar rental at my phase 1 airport.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>3 hours.
