Brief Description:	Upgrading the wing spars
Spen the late afternoon and early evening at Bob's house drilling out the solid rivets in the main spar to replace a portion of the light weight L angle on the top spar cap with a much thicker 1680 mm aluminium extrusion. We drilled out all of the solid rivets on one wing and back drilled the extrusion.
