I have been looking into the geometry, and it seems that today ogees are universally depicted as 2 curves of the same radius, one rotated 180 degrees. That goes for diagrams in this article, other articles online, and for almost all ogee router bits (and every ogee router bit I found that specified the radius of the curves. Sample size: several dozen, I didn't count.). The curve is usually 90 degrees, except for large radii (and I suspect that is likely due to the common thickness of wood being around 3/4 of an inch).
But if you look at antique ogees, such as either of the stone arches pictures on this page, or the 2 Victorian moldings from my house that I just measured, the concave curve has a larger radius than the convex curve. And the curves seem to be around 60 degrees (based on eyeballing the 2 pictures, and in the 4 curves I measured on molding: all 4 appear to be 60 degrees of a curve before tapering into the next shape.)
Obviously those are small sample sizes. I would love to have more. Would also love to have a more mathematical description than "tapering."Skintigh (talk) 03:57, 29 October 2021 (UTC)[reply]
The photos are good illustrations but do not clearly identify which elements are of the shape being discussed. A diagram in which the shape is isolated would be helpful. Jim (talk) 15:48, 8 July 2009 (UTC)[reply]
The picture of the clock doesn't seem to contain any Ogee curves (unless you count the beehive), and the title is definitely incorrect: the moulding of the clock is square bevelled, not Ogee.
