Mechanics
The pencil portions of the "Pivot Pencil" consist of two (2) wooden pencils in matching flat-octagonal columnar designs, and have total
measurement of seven-and-three-sixteenths inches in length by nine-sixteenths-of-one-inch in width by five-sixteenths-of-one-inch in height (7
3/16" x 9/16" x 5/16") when attached.
The hard graphite leads within the wooden pencils have rectangular columnar designs and total measurement of approximately
seven-and-three-sixteenths inches in length by one-fourth-of-one-inch in width by one-sixteenth-of-one-inch in height (7 3/16" x 1/4" x 1/16").
The swivel joint that connects the two (2) pencil portions is made of an alloy steel material, and measures one-and-three-quarter-inches (1 3/4")
in total length. The female end of this swivel joint has a length of eleven-sixteenths-of-one-inch (11/16"), its male end measures
one-and-one-fourth-of-one-inch (1 1/4"), and the outside end of this swivel shaft measures three-sixteenths-of-one-inch (3/16").
This swivel joint fits into a truss head slot of 6-32 by one-fourth-of-one-inch variety (6-32 x 1/4") found within the pencil portion. At the
swivel joint connecting points of each pencil end, the pencil portions are tapered to forty-five degree (45º) angles to avoid interfering contact
with the swivel joint allowing for full angular adjustment.
The swivel joint is encased in a single-ply of heat-shrunk ethylene propylene diene monomer (EPDM) of one-eighth-of-one-inch by
one-sixteenth-of-one-inch (1/8" x 1/16") dimension.
