PS Now Wearing says some constructions have face side out, and some in. I would like to hear about ones which are better with face sides out, please.
In "The Essential Woodworker", R.W. makes it a point to call it the "true face" to distinguish it from a "show face" or "show surface". Same goes for "true edge".
I think this terminology eliminates most of the confusion about the purpose of the edge/face.
Later in illustrations showing how to layout for a mortise and tenon in a small table, he has the true face and true edge of the leg facing out so they are the show faces. As this is a table with a small reveal between the leg surface and the apron, it makes some sense.
The legs should obviously be very CLOSE to the same size (if not identical but hey, whose counting molecules anyway?). Otherwise the aprons would be of different length shoulder-to-shoulder and that can't be good practice!
In his illustrations, the aprons would also have their true face out (and I would have though true edge up to meet the table-top but it is shown DOWN). Now the absolute thickness of the aprons isn't critical as any variance is thrown to the inside. However it would look odd to have one aprons 1/2" thick and the rest 7/8" thick. Throwing the waste to the inside isn't an excuse for being excessively sloppy either.
Is this the absolute, be-all and end-all method for preparing stock and laying out? Probably not. But it does work. As with most methods, one must engage brain before engaging the work. Thinking through the process is the key.
(I shall go find a comfy chair in which to sit while being politely eviscerated by David C. and others.)
((edited to clarify remark about face edge orientation))
