Well, for a lot of planes (Bird of Time is one of them) the discoverer doesn't give a standard airfoil that we could look up coordinates for. (For the BoT, Ol' Buzzard tells us that he built 12 of them before he arrived at the published version, that the idea behind its airfoil was to use a thin profile. He tried sections as low as 8%, but he said he used 9% on the plans because he found no performance improvement by going down to 8% and he could build a stronger wing at 9%. He also talks Phillips entry, so he may have started with something standard, say NACA 2409 and effectively increased the camber by raising the entry point.... effectively reinventing something very close to a NACA 3409 (which is essentially a flat-bottomed foil with phillips entry and overall proportions to match the BoT.

So, I would start by printing out a 3409 and an enlargement of the Bird of Time airfoil and see how close they are... you can adjust the NACA foil to try and match the BoT one and you may just get exactly what you're after.

If not, one thing you could do load a scan into a CAD program as you mentioned, but rather than drawing the curves manually, use a minimum number of points and have the spline function of the CAD program fit a curve to them. If the points are placed well and the tangent angles at the end points are locked in parallel to those of the original foil, a very good match should be generated with just a few splines (and so with just a few points defined). It is best to keep the number of points to a minimum and adjust the shape of the curve by moving points along the desired shape that you get from the scan. Once you have a good fit this way, you can throw a set of verticle lines over the airfoil and pluck off the coordinates at the points where they intersect the airfoil curve.

I'd bet that some of the CAD whizards know quicker methods of pulling off coordinate data, but the basic method should work.

Do you have a setup you can experiment with? A CAD program loaded and maybe a scanned plan of the Bird of Time?
