Last night I began chiseling out the knuckle joints. Tonight I finished, and proceed to lay out the ogee at the bottom (you can see I have also begun to resaw the stands). An ogee is simply a convex curve next to a concave curve. The radii of these ogees are the same. I used a marking gauge to consistently measure feet in from the sides of the stand. I then use a center rule to determine the center, and to mark it the rule's width from the stand's bottom. I then connect the feet with the center mark in pencil.
With a compass, I determine half of this line's length, then draw a radial arc from the halfway point, and the stand's center, meeting as you can see above the line. I then use this point as a center to mark a radius from the peak of the triangle to halfway along the line to the stand's foot, marking the top half of the ogee.
I repeat the process for the bottom arc. Since the centerpoint lies somewhere off the below the feet, I must somehow extend it. Though I could probably get by just securing it and drawing on the workbench, I decide to just use the other stand, because it is the same thickness. I pop up a benchdog far enough from the end of the bench so the stand being marked on hangs over the bench. As I lean against it to look overhand to mark the center, I lean into and secure the near stand against the stand being worked on and the benchdog. This ensures the bottom centers stay referenced to the far stand. The ogee is formed.
Then cut. The purist might advocate the use of a comping saw, going slowly.
Next, the top ogee, separation of the leaves, and finish.
