Brief Description: Building the Rudder Skeleton contd.
I spent most of my time deburring, dimpling and edge finishing the parts. There were several holes in the ribs that I could not dimple with the tools that I have so I ordered a pair of vice-grip dimplers from Avery. I also got the smaller Scotchbrite wheel set and a VAF hat. Shortly after I placed the order I realized that I needed a #10 drill, countersink and dimple die. I guess I will be placing another order in the near future. I drilled the aft three 3/32 holes in the upper edges of the rudder skins to #30 and dimpled them. I machine countersunk the R-916 trailing edge wedge. Either I really screwed up or the anticipation was much worse than the reality. I used a variable speed electric drill rather than my high speed Sioux air drill and clecoed the wedge to a sacrificial piece of MDF. I gradually "snuck up" on the proper depth. It seems to have gone well and the wedge appears to fit nicely with the dimpled skin. I need to finish dimpling the ribs and countersink the lead counterweight before priming and assembly of the skeleton. I moved on to the elevator stiffeners cut them to rough length on the bandsaw. I began to trim the flanges but then decided to call it a day.
