  Stool & Apron Miters  
I'm trying to work out the problem of the self-return miter on the stool not lining up with the back edge of the casing, as Derrell Day pointed out to me in Portland. Here's my thinking. Let me know what you think?
Lining up the miters on the head cap and the bead molding on this classical door head is 'relatively' easy, especially if the material is milled with that look in mind.

Of course, if the head cap is a lot wider, especially the fillet on the bottom, then the overhang beyond the frieze must be longer--the wider the cap, the longer the overhang. At a certain point the molding won't look properly scaled.
But aligning the self-return miter on the stool to meet the back of the casing involves other 'relative' points.
First, maintaining an even reveal along the bottom of the stool, between the cove and the bullnose, is important, and so is aligning the miters on the stool, cove, and apron.

It seems to me the only way to align the self-return miter on the stool with the back of the casing is by making the o.d. length of the stool shorter. (You could make the stool wider--not rip as much off the back, but that's not always an available choice, given different wall conditions, window types, etc., and besides, the same 'relative' issues--stool/cove/apron miters aligning--remain no matter how much wider you make the stool).
And most of us think that the apron should line up plumb with the back of the casing, right?
I guess it really doesn't have to. Here's a couple photos from an historic home in Columbus, Ohio. I think the stool and apron looks just fine with the cove molding plumb to the casing. Though I'd have to see a lot of other historic homes before I'd say this is right. In the photo on the left, the apron does look kind of short or 'light,' maybe 'abbreviated,' huh?

But I don't see any other way to align the back of the casing with the self-return in the stool, I mean, when working with a bullnose stool and cove molding on top of the apron. I guess the only solution here is NOT to self-return the stool and mill that end, just as Henry P. has been saying!

Any other suggestions?
