Today I dimpled and countersunk the parts needed for completing the baggage area. Most of the work was dimpling the floors, but some countersinking was needed in a couple of places.
Dimpling was easy enough, although I made a mistake and dimpled the 4 CS-4 rivet holes using my regular #30 dimple dies with 120 degree dimples. I then realized my mistake and redid them with my 100 degree dimples dies. Not great, but it will be ok. I correctly dimpled the corresponding rib holes, after I carefully measured to make sure I identified the correct holes.
