I’m in the midst of a big framing job—a polyptych of four abutted cassetta frames in quartersawn white oak to house a 17th century map in four panels.
Helping unify them is a sight edge molding with a running beaded pattern. Beads are part of the basic vocabulary of frame design. The pattern here—taken from the border of the maps—has three beads in a set, the sets spaced a few inches apart. The whole polyptych is about 15 feet long, so the beaded molding has 234 beads.
The first two steps, which aren’t shown, are, 1) selecting the wood, which is crucial to the ease of carving, especially in a coarse wood like quartersawn white oak; and 2) milling the shape, which is a 5/16″ wide bead with a narrow cove (see first photo below). Also critical to carving is keeping the tools sharp.
My bench, which I discussed a bit in my recent post, “Tools of the Trade,” but is more visible here, is designed for exactly this kind of work. It has two front-mounted vises with especially wide and long jaws for holding lengths of molding and providing a wide surface to rest my hands on, which is necessary to proper control.
Here’s how beads are carved.
Final note: For efficiency, each cut should be done in multiples, going down sequentially the length of the molding—or at least each set of beads. I tended to do the first three cuts (the v-tool cutting across the grain, and the two initial cuts into the valleys between the beads) down the whole length of molding, and after that focus on each set of beads, but still doing each cut in sequence on the full set of beads. With that approach, each set takes about five minutes.« Back to Blog
