Deburred all holes the F829A-1 front seat floor, then scuffed with maroon pad. Used the DRDT-2 to dimple all of the #41 holes in the floor. Cleaned with MEK-bla bla bal-then shot it with primer. While the primer was drying, I began riveting the footwells. Was able to reach all of the rivets except the two in the corners with a regular yoke, then switched to a 4” nohole for the corners. One corner rivet just wanted to cause me grief. Drilled it out twice from the back side. The hole wobbled out a bit, so I drilled it to #30 and used an Oops rivet. This time I backriveted and it worked out ok. Next I clecoed the F805C-1 floor support angle to the seat floor. I used the 4” nohole yoke to set all of these rivets. Turned out quite nice.
