More Horizontal Stabilizer Spar Prep

 Got started by marking all of the spar cap strips.  You have to trim tapers on the ends of them.  Just mark them per the notches in the parts per the directions.

 Then I used the band saw to trim them all.  There are 2ea of 3 different ones for 6 total.  I always cut to the outside of the line and use the smoothing process to bring the cut to the line.

 Then I smoothed out the bandsaw cut marks.   Be careful to not remove too much material and end up with edge distance issues.

 Then I clamped one of the front spar caps into place.  Thes are bowed out of the box so use plenty of clamps and force it down into the right place.  The trimmed flanges sit on the spar web.

 Then I match drilled the double and spar holes to the spar cap.

 
Removed all the cleco's and clamps and cleaned out all the drill chips.  Then put it all back and then match drilled all of the spar flange to spar cap holes.  There are a ton of them!

 Side one complete.  Now time to do the other side!

 Side 2 #30 holes done!

 Drilling side 2's #40 holes.

Front spar caps all drilled to the spar and spar doubler.  That is a ton of holes!  Aluminum chips everywhere!
