While checking out the drawings to make sure I don't miss anything, I found this one hole called the rudder cable clamp hole that needs to be drilled to #19 and dimpled #8 BEFORE riveting. So I did. This is not mentioned on the plan, just on the drawing showing the rivet patterns.
For deburing the skins I found it easy to use my new little electric drill rather than due it by hand. This is fun to use, holds the bit straight, and is fast.
