Used with a bar clamp. Say the bar clamp is clamping a glued up pane. This
piece lets you put presure at points accross panel to keep it level. Could
also make a banding clamp where short bar clamp clamps against on edge of a
panel or board and this piece clamps against the edge to attache solid
molding, etc. Lastly with many of these and many bar clamps and some
cldrons - coul dbe set up as veneer press.

It is one head of a multiple head bar clamp that relied on a single piece of
flat bar steel to hold long sheets or faces against a long surface. Imagine 50
of these in a row on one long 3"x1/4" ribbon of steel.
