December 6th 2007 - 4.0 hrs - 52 hrs  total - Bought a variable size hole
cutter.  Started cutting out lightening holes.  After a few holes found it
much easier if I tacked the two same-sized ribs together and cut both ribs
in one shot.  Cutter wroks extermely well.  Nice clean holes EXACTLY
the size they need to be.  Will need to lightly sand them at some point.  
Got most of the holes cut, but still have a few more to go.
The varible size hole cutter works really well!
Got a lot of them cut, but still a few more to go.  Note that each rib in this
picture is actually two ribs tacked together - one for each side of the tail.
