Since I'm waiting for my countersink bits and micro-stop (should be here Wednesday), and my spar caps (should be here Tuesday), I began working on the left wing spar webs.
Although nearly identical to the right wing spar webs, the order of the 4 web pieces is slightly different, and the location and orientation of the W20-02 and -03 wing root rib attach angles is different. So once again, you have to pay attention to the plans.
