Labeled all parts of the front and rear spar, identifiying left and right so that parts can be reassembled correctly. Mounted 3m Scotch Brite cut and polish wheel on bench grinder. Used wheel to polixh away any burs on HS 904 Main Ribs. I removed the other wheel to make more room. I used my die grinder and 3m blue ultra fine polish discs to remove burs from lightening holes and notches in Rib Flanges.I finished 5 of the Main Ribs.
