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.
