The Root Rib Attach Angles were drilled at the required locations. The four Radius blocks were cut to size using material removed from the Root Rib Attach Angles. The Tip Rib Attach Angles were cut from the supplied Z01-03 formed aluminum stock. The parts were cut to shape, marked and drilled. I discovered that I drilled one of the parts incorrectly and will need to make a new part. Oh well.
