Cleaned up fuel system hard points installed yesterday. More sanding of previous glass work. Did some work planning the installation of sight guages. Decided I had room for the larger guages so put this project on hold until guages arrive. Made several templates for the baggage area window. Decided on a viewing area of 4 3/4" X 21" with half circle ends. Cut inner and outer strake skins to accomodate window. Cut 6mm plexiglass to a dimension 3/4 inch larger all arround (6 1/4 X 22 1/2) to facilitate installation. Bondod in window to set position.
