Flush panel
A panel that is level with the surrounding frame. This flush bead-butt
panel shows how the bead is worked on the vertical sides of the
panel. With the face of the panel finishing flush with the frame,
the top surface of the bead is set about 1/16 to 1/32 inch lower
than the frame. The panel is about two-thirds the thickness of
the frame.
Frieze rail
The second rail down when the door has four rails.
Folding wedges
When two narrow framed and paneled wood doors are put together
to make double-margin doors, the two wood doors are fitted together
with several pairs of folding wedges. The wedges are set in the
mortises and banged together so that they slide past each other
and tighten.
Foxtail wedging
The mortise is stopped about 1/2 inch short of the back edge of
the stile and cut slightly dovetail in shape. The tenon has a
saw cut 1/8 inch in from each side, into which a wedge is inserted.
When the joint is put together and clamped, the wedges spread
the tenon and lock it in the mortise. This joint is used on top-quality
wood doors when you don't want to see the end grain tenons penetrating
the stiles.
