Cam-Lock Drill-Press Vise: Holed Steel Bed, Pinned Jaws and an Eccentric Cam (Popular Mechanics, 1920)
C. H. Willey's quick-acting vise for the drill-press table (Popular Mechanics, 1920): a 1/2 x 3 in. steel bed drilled with 5/8 in. holes 7/8 in. apart and bolted down on slotted end pieces, a fixed jaw pinned into any hole, a sliding jaw kept on the bar by a riveted cross pin, and an eccentric cam on a handle that locks the work.

Make the bed
Make the bed
Cut a bed bar from 1/2 x 3 in. (13 x 76 mm) steel to suit your table (length ours). Drill a row of 5/8 in. (16 mm) holes 7/8 in. (22 mm) apart along its middle.

Cut two short pieces of the same stock, slot them for bolts to the drill-press table and fix one under each end of the bed (ours: bolted), so the bed stands clear of the table.

Make the fixed jaw
Cut out a steel block underneath so it straddles the bed (stock and size ours). Drive a pin into it, downward, that fits the 5/8 in. holes.

Cut a second block the same way. Pass a horizontal pin across the opening below the bed and rivet it to the jaw's sides, so the jaw slides along the bar but cannot lift off.

History and honest limits
From C. H. Willey, "A Simple Drill Vise", **Popular Mechanics** vol. 34 (November 1920), p. 3340 (checked on the archive.org scan of Popular Mechanics Shop Notes, popularmechanic00unkngoog). He gives only the bed section and the hole size and spacing; jaw and cam sizes, the bar length, how the end pieces are fixed and the cam offset are ours.
