Actually, it wasn't as bad as i was expecting. Yes, there is fiberglass dust, but not any more than aluminum dust. I measured 0.75" on each flange and cut to that line. I ended up using a tungsten carbide jigsaw blade in a jigsaw to make the initial cuts. posted at: 19:24 \| path: /aviation/build/airframe/fuselage/sec43 \| permanent link to this entry \| add a comment Battery Cable Firewall Passthru (3 hours) After some debate, i decided to stick to the Van's plans for the battery cable firewall passthru - basically a SB500 bushing. I did also wrap the cable around the braided wire wrap, which is pretty tough in itself. Later, I will also use some kind of sealant to seal out gases and to prevent vibration. posted at: 19:18 \| path: /aviation/build/avionics \| permanent link to this entry \| add a comment Section 23: Aileron Actuation (10 hours) Cut all the tubes and primed them inside and out. At first, i could not find the steel aileron collar tubes. I thought i was missing them and even asked for it to be resent by Van's. However, i was looking for a powder coated part, when in fact, it's raw steel. It was actually used as a hinge holder when shipped, which made me think it was just scrap and not a real part. Also, it was not even labelled. Priming the torque collars was best done by pouring some primer into a ziploc freezer bag, then dunking the tube into the bag. I screwed up the aileron control tubes. Instead of measuring for 21 11/32, I measured them to 21 11/16, accidentally. Crap. Screwed - need to redo it later. For now, I cut these down to the right size and just temporarily fit the fittings on for now. A GREAT tip for fitting the fittings onto the ends, is to use a heat gun to heat up the tube to expand the metal. Makes inserting fittings into the ends, even with primer, easy. posted at: 19:00 \| path: /aviation/build/airframe/wings/sec23 \| permanent link to this entry \| add a comment Section 40: Flap System (1 hour) Second safety wire job, ever. posted at: 18:58 \| path: /aviation/build/airframe/fuselage/sec40 \| permanent link to this entry \| add a comment Section 39: Control System (1 hour) My first safety wire job. posted at: 18:54 \| path: /aviation/build/airframe/fuselage/sec39 \| permanent link to this entry \| add a comment Strobe Kit 1. Bought this strobe kit from Russ Daves. 2. Confirmed it works fine. Had to convert an old computer power supply to supply a 12v supply for testing. posted at: 18:39 \| path: /aviation/build/avionics \| permanent link to this entry \| add a comment Section 17: Outboard Leading Edge (8 hours) 1. Final riveted the outboard most rib. Left this undone so that installing the Duckworks mounting bracket would be slightly easier. 2. Installed the Duckworks lights. Drilled and installed the nutplates onto the ribs. Created the mounting brackets for the lights to span the 15.5" span between the outer 2 ribs. Cutout the hole for the lights. Used a jigsaw. Then sanded down with a 1" drum sander. My first use of it, and i love it. posted at: 18:36 \| path: /aviation/build/airframe/wings/sec17 \| permanent link to this entry \| add a comment Section 18 Photos: Fuel Tanks posted at: 17:29 \| path: /aviation/build/airframe/wings/photos/sec18 \| permanent link to this entry \| add a comment Section 18 Photos: Fuel Tanks posted at: 17:29 \| path: /aviation/build/airframe/wings/sec18/photos \| permanent link to this entry \| add a comment
