Brief Description: Aileron boots & elevator fitting
Spent ¾hr drilling and countersinking the fuselage side skins for nutplates where the aileron boot reinforcing rings will go. I went with #6 screws in the end. The top two nutplates are MS21071 short one-legged jobs and capture the mid-longeron. The other two are standard length one-legged MS21051 and a normal K1000-06. I've scotchbrighted and masked the aread around so next time I'm priming, which won't be far away, I'll throw some around that area. I also need to primer the left front lap belt bracket where I cut off the part that holds the standard Vans air vent since I am using SteinAir 2½" vents and Classic Aero stick boot cover which didn't fit until it was trimmed away.
After a short TV break I decided to go out and take a quick look at what was next. An hour and a quarter later I had the elevators fitted ready for drilling the elevator horn tomorrow night. Its a real struggle to see what size and number of washers you need between the elevator control horn and the VA146 bearing because the vert stab spar is in the way and you can't see. Not to mention how tricky it is to actually get the washers in there in such a limited access area.
Anyway, here's a little trick: get all your drill bits in as close sizes as possible; I have a full set of metric and imperial. Now keep passing the shanks of the drills between the bearing and the control horn until you find one that *just about* squeezes through. Take your digital calipers and measure it. In my case, both sides, it was 3/16", or 0.185" in decimal. Now build a washer stack, including the big flat one that sits next to the bearing, until you get as close as you can to your measured size. Remove the big one, and place the remaining AN960-416(L) washers on the shank of a 1/4" drill bit. Use a dab of superglue (just a dab!) to hold them together and wait until the glue is fully dry (usually around 30 seconds or so).
Now place the single washer stack into your Avery washer wrench/holder and insert into the gap using a smaller that 1/4" drill bit or some
