Dan & I took apart the left hand spar and prepped the parts from priming. Our method starts with deburring, then 3M (of course) 120 grit aluminum oxide sand paper, then 240 grit and a final pass with red Scotchbrite hand pads. It is amazing how many little scratches happen when you handle these parts so much. The long web parts took a while. The spar caps needed a lot of work with all the drilled holes for the webs. I was using the sand paper and it went pretty slow to get the dings out. Later on Dan tried light pases with the vixen file and it worked great, still needs to be cleaned up with the sandpaper but really fast. Oh by the way we use gloves when we sand because the aluminum dust will make you hands really dirty.
