Finished up drilling rivet #11 and bolt holes reamed .198, then counter sink the AN427 rivet and bolt holes per drawings.
Took spar stack apart, debured holes, cleaned spar edges with marron rolok pad on right angle die grinder and put everthing back together with tempory bolts in the holes were NO rivets will go for now. Loaded all the rivets in place and put blue painters tape over them so the rivets wouldnt fall out.
