No pictures today, as there wasn't much major visible progress (MVP). I finished deburring all the rudder parts and then moved onto dimpling them.The rudder spar has the holes pretty close to the web so I used my skinny close-quarters female dimple die to shape those without deforming the bend from the web to the flange. The aft three holes on the bottom rib are also a challenge as the rib is extremely narrow at that point so to get the dimples formed, I had to bend the flanges out, use the pop-rivet dimple set to create them, and then bend the flanges back.
I then dimpled all the skeleton bits, one of the skins, and didn't do the counterbalance skin as I still need to taper the back edges of that where it overlaps the rudder skin.
