Continued Cleanup of the Wing Spars

Today I am continuing with the cleanup of the wing spars. I’m using a small half sheet sander, my sanding block and scotch brite. I completed the two lower spar caps. Next I’ll work on the upper spar caps. These I won’t be as fussy about the machined of flange. The plans allow it to be proud by up to one sixteenth so I’ll just focus on cleaning up the machined edges and getting rid of the scratches.
