With the installation of the shear webs "locking in" the washout, the washout tabs on the bottom of each rib can now be removed. I used a razor saw to cut away the tabs on the plywood ribs, and an Exacto knife to remove the tabs from the remaining balsa ribs. If you are going to be "off", it is better to err on the side of leaving too much material -- as this can still be sanded to the proper airfoil shape; than to cut into the airfoil, thereby altering its shape.
When using the razor saw, be sure to hold the end of the saw away from the trailing edge sheeting.
