Brief Description: .125" shims on center rib jigs + info
Nothing exciting here. Just added 0.125" shims on each end of the Center Rib Routing jig. After countersinking the screw holes, the pieces were clamped in place and drilled for 1" coarse thread wood screws. I then used the belt sander to bring the shims to the wing contour. (1 shim on the aft end and 2 on the forward)

(Thanks to Dan Melton, Wayne Massey, and John Rheney for backing me up on my calculations)
I'm not counting the time here, but I spent a good chunk of the day cleaning the ENTIRE shop in preparation for the sheet metal work. I have a 4x12 sheet layed out right now, just waiting on me.
