Tested all the glue test blocks so far. As desired, all the breaks were at the wood and not the glue. Carry on.
Glued the last of the stringer and stiffeners in place.
Spent some time going over various glue joints and filing and sanding away excess glue. Not really necessary but my OCD makes me do it. I guess it's reducing the overall weight of the airplane by a few grams at a time. Lighter planes fly better anyway. Especially if/when doing aerobatics.
I was so pleased with the outcome of the new retract indicator pin, I decided to clean up the other one. A few minutes with some sandpaper, starting at 400 grit and working my way to 2000 grit removed the surface scoring and grime and oxidation. Removed the original red paint and then cleaned the pin and gave it a new coating of red on the end and at the midway point. Photo shows left to right, the original damaged pin, the newly restored original pin, and brand new pin from a couple of days ago.
