Drilled the holes into the rear spar of the horizontal stabilizer

I drilled in the initial holes through the vertical bars into the HS rear spar with an 1/8" drill bit. Then I drilled the holes to there final 3/16" size from the HS rear spar into the vertical bars from the rear. The temptation here is to use a #12 bit here. But a #12 bit is a hair larger than a 3/16" bit. So the 3/16" bit makes for a nice tight fit for the AN3 bolt that goes into these holes.
