Forged C-Clamp with a Tapped Boss and Swivel Pad

A C-clamp (or G-clamp) is a C-shaped steel frame with a screw through a threaded hole at one end: the screw presses a swivelling pad against the work, turned by a small bar through its head. Forge the frame from flat bar, tap the boss, thread a rod with the die, and peen a pad onto its tip. The picture: a G-clamp drawing, with its pad, screw and tommy bar.
