Door Vises for Edge Mortising
When a design called for ten swinging doors, the vises described below (common in the construction industry) enabled us to hold the doors on edge securely while quickly mortising them for hinges and strike plates.

MATERIALS FOR A SINGLE VISE
One 2′−0″-long 2×4: base A
Two 1′−7½″-long; 1×4s nailing strip B: fixed jaw C
Two 1′−7½″-long 2×4s: movable jaw F and movable jaw support E
One 3½″-long 1×4; ledger strip G
Four 3½″-long pieces of ⅛″ × ½″ steel ...
