I started making the wing jigs used to allign the center spar section in the fuselage, I made the left and right inserts at the same time and then started assembling the left jig. What looks simple takes a long time, what with checking that its all level. setting the front at 81 degress and the rear to 77.5 degrees I think. Anyway there where angles involved and it was time consuming and really realy cold in the garage.
