Drilled Arm Rests; Mulling Side Skin Roll
The plans say that you 'may' flute the arm rests...but it looks like to me like it's pretty much necessary. Yesterday I clecoed them to the side skins, but they really didn't fit very well...so I went back and fluted them. It's pretty much a mandatory process, if you ask me. After fluting the arm rests, I drilled them to the skin.
Then I drilled out the hole in the left side skin for the step. The plans pretty much leave you hanging here. I can't find *any* drawings for the step kit. I bought the steps from another builder so I'll ask him if he has anything. Anyway...the plans don't have any dimensions, but the step tubes are 1.5 inches in diameter. In the matronics archives and other places, I've read where people have to make the hole a little larger for the weld beads on the back side of the step plate...so that's exactly what I did. I just cut it to about 1.80 but I I still had to enlarge it more for the bead to fit through. I did the enlarging with my brass-handled deburring tool.
I also started contemplating how to roll the transition on the skin. This roll transitions from the 90 degree angles of the fuselage at the wing to the curves that transition from the bottom to the sides on the aft fuse.
