The Seattle Eastside EAA met tonight and we were treated to a fine lecture on the certification process. The talk was given by one of the two DARs in the Seattle MIDO.
I added up the lengths of all the (L) brackets and determined I had some good room, so I re-fabbed a questionable bracket for one of the horizontal stab's spars. The "ruined" piece was then used to test various methods of deburring ( file VS scotchbrite VS drill bit ) and to test the rivet gun Zenith supplied. About 15 minutes were spent.
