It's actually rather simple with the lofting program I use to lay out ribs from either straight, to several forms of "Geo" style angled ribs. I can even generate "Eggcrate" interlocking style ribs, with elliptical wingforms, if desired.
Bob is right that perfectly good ribsets can be cheaply made from his system, and building in the foam cradle assures a straight wing. I believe what is being missed by some, and alluded to by Doug, are the benefits coming from marrying the two systems, "Lost Foam", and Laser Cutting . Sure, it's at an increased cost, but accuracy, ease, and speed are the results of such a merger. We already are willing to pay a decent premium for speed when we go to using the often heavier foam wing.
One also has to consider that once the outline at the rib station has been achieved by hand cutting, the internals, such as lightening and bellcrank clearance holes must be laid out and cut. A set of ribs cut to work with the foam cradle can save time and some frustration, though at a cost.
National Balsa is one company I've worked with, that will sell you the balsa, and laser cut it to your files. The price is reasonable.
If I can find where I stored the 4 digit airfoil files for the Legacy, I might give it ago myself.
Bob, as innovative as you are, I cannot see how you aren't all over this, as a speedy alternative to grace, and inhance the user ability of your already excellent "Lost foam" system.
It seems like a win-win situation to me.
If I can be of help, drop me a line.
