So after drilling out all the rivets in the HS parts to salvage from the over countersunk spars I decided to REPLACE all the parts instead.  My thought is that I want all the holes to match as closely as they can and the salvaged parts had holes that were match drilled into other parts as well as holes that were slightly enlarged by the force of the rivets I drove into them.  I also looked at the edge distance on the HS-905 nose ribs and found the first (8) I deburred and match drilled were no good.  I was excited to ensure I removed enough material so they would not leave dents in the HS skins…… needless to say I will be setting those aside for the static display RV-10 I may get around to building with all the scrap parts!
