Building 4 Star 60 Day 16 & 17: All About the Sanding

Monday I headed to Peters after driving back from Dryden.  This made it a shorter session that involved a lot sanding!

First off I sanded the top and bottom trailing edge sheets until the were flush with the trailing edge piece glued earlier.  I also sanded the edge of the ailerons that will be facing the trailing edge of the wing to be level and flush/straight.  Seen in the first and second pic below, respectively.

Tuesday I saw how how Peter glued and clamped the laser cut lite-ply wingtip to the outboard end of both wing panels.  You can see in the pick where he used some filler to get things to fit snug.

My task was to sand the filler flush as well as to make the hinge slots, Peter already had marked where they go, in both of the trailing edges as well as on the leading edge of the ailerons.  The other major task for the day was to sand the wing dowel support blocks flush with the ribs and then ‘carve’ out a grove in the wing dowel support blocks so that when I apply the sheeting over the wing it sits flush with the leading edge.
