Brief Description: Marking wing skins for rivet lines.
The top skin is thinner than the bottom and therefore even more easily damaged, so careful movement and handling is required.
After tracing the outlines of all frame parts, and in order to be able to use the table for marling the rivet spacings and pilot hole drilling, I hoisted the wing frame up out of the way.
The centre lines of all parts was then marked and using the rivet spacer, I started spacing the rivet hole positions (32mm for stringers & spars, 64 mm for ribs).
