I added two stiffeners to the right side of the cockpit side console, and now the console is rock solid, even with considerable pressure applied to it -- the way a person aggressively throwing switches or climbing in and out of the cockpit might behave. I also removed one of the stiffeners that runs along the left lower edge of the console and will replace it with a beefier one. This is the edge of the console that my right leg will probably rest against in cruise flight, and I don't want it to flex at all. This thing will probably be WAY overbuilt, but I think that's OK.
I began countersinking and dimpling the various components of the console where needed, and I scuffed and primed several attach angles.
Then I spent a rewarding hour laying out switches and panel components to get an idea of how much room I actually have on the side console and the side instruments panels. I drew some layouts and rearranged switches based on how I think I'll use them. It's interesting how my perception of good a layout has changed now that I can actually see the components and the space they'll occupy.
Finally, I spent some time laying out the autopilot pitch servo and ELT, and planning how I'll mount them in the aft fuselage.
