It becomes a funny diversion; what are these called – both today & in the 17th century. The old name is easy – we have no idea what the joiners who made ’em called ’em. Furniture historians often call them “glyphs” – but most architectural definitions call a glyph a vertical groove or channel.
whatever they’re called, here’s how I made some today for the carved box with drawer. This batch is walnut. Essentially I make a run of molding that is peaked, then cut it up. I took a scrap about 15″ long, by about 9″ wide. Planed a straight edge, then marked the middle of it, (this board is just over 1″ thick.) also marked the thickness of my glyph – 3/8″. Then planed two bevels down almost to the scribed lines. I needed about 4 feet of this stuff; so I did this to both edges of the board, a couple of times. I made extra so if something went wrong in trimming I wouldn’t need to start over.
Here’s a close up view of the planed result.
here’s how I held the board – the single screw is next to useless – it just pinches the board while I get a mallet to whack the holdfast. Then I sawed down both edges, I sawed in the waste area, leaving stock for planing the backs of this molding.
This is one of those rare instances when I will say to you – be careful if you do it this way. It’s hard to tell from this photo, but I’m pulling the molding to plane off the saw marks – much like a cooper will plane the edges of his staves. Need a sharp plane, set fine. And focus. One slip…and you feel real stupid.
Then saw the pieces to length, and use a chisel, bevel down at first, to shave each end of the glyph. Or whatever it’s called.
Here’s some from a chest with drawers made in Plymouth Colony, c. 1680s or so
I have mine cut and glued onto the box with drawer. so that’s the first piece built for the next joinery book. Next week I’ll apply a finish & photograph it.
