Oops, wing leading edge blocks are glued on AFTER wing is completely sheeted. The sub leading edge is sanded the shape of the rib airfoil, then the sheeting overlaps that. Then of course last is the leading edge block. Your way will make it more difficult. Nitice no leading edge yet in the picture.
Trust me, I've built a few of these![8D]

Leading edge blocks 20-A, 20-B and W21 were glued to the leading edge at this stage, no sanding yet.
