Deburred all the remaining holes int he VS parts and skin. I took a tip form Muike Howe and put my hand squeezer in my vise to dimple the rib flanges that the DRDT couldn't do. This was easier than trying to hold the squeeser and part at the same time or putting the part in the vise--it went very quick. The cordless screwdriver with a small debur bit on a 6" hex shaft made quick work of deburring the skin holes. I'd probably still be at it if I wa doing it manually. Also got one side of the rear spar CSK'd per the plans.
