This is boring but it has to be done. Now that my 4 spar assemblies are all apart every hole and edge must be deburred and preped for priming. I am just getting into the groove of this and got two sections of spar web and 1 cap strip deburred. The bearhawk group gave some good advice on speeding up the process. I am going to use a cordless screwdriver to debur rivet holes. The rest is not so bad. Dread it when I get to skining the wings.
