Hi,

One thing that worked well for me in creating the under-camber was the new hand power planner from Great Planes. I carved the under-camber in before creating the airfoil shape. I just clamped the wood onto my bench and made a stop the length of the wood to slide the power plane against. By adjusting the stop and the depth of the power plane it was easy to create the under-camber. It required just a little hand sanding to smooth it out.
