The past couple of days represented quite a bit of progress on the rudder, but without major visible results simply because this assembly involves so much effort. I dimpled everything that requires dimpling (hopefully), and then primed a few parts. Need to go back to NAPA for another can of primer, though -- and am also considering whether I should powder coat the rudder horn and rudder horn brace. (More correctly, whether I should farm them out to a shop -- Harbor Freight powdercoat sucks.)
Finally, I clamped a piece of wood to the bench and match drilled it with the trailing edge angle aluminum. Then I started countersinking 3/32" holes in it -- in anticipation of riveting the rudder's trailing edge. The Net is full of various opinions about this particular issue, and I see that others are particularly concerned with making certain that the edge is straight and true. You'll be reading more about this as I continue.
All of the workshop time today was without the neck brace. Karin says that I seem to be hunching forward though, so it's back on again as I post this entry.
Time: 5 hours
