John, I built two B wings and a D wing from Platt's plans and, in preparation for my fourth, I decided to redraw the wing to reflect the changes I wanted to see in construction. Dave's jig method leaves much to be desired in my opinion and, quite honestly, I don't know how he builds the wing as recommended and keeps it straight. My plans are drawn in CAD and are basically laser ready. If you are interested in building my version of the Platt wing then let's talk. I can also do the laser cutting if we can reach some agreement on the cost to do so.
