On Big Projects, Pull Straps Tight with One Handed Bar Clamps
When you don't have enough band clamps or your band clamps won't reach around a project, you can fashion a good substitute from any strapping material and a one-handed bar clamp. The one-handed bar clamp also will give you considerably more clamping pressure than the screwdriver-operated tension mechanism found on band clamps.
Start by opening the jaws of the clamp as wide as they will go. Then, tie one end of your strapping material to the non-moving jaw of your clamp. Wrap the strapping around the project with a loose fit, as shown above, tie off the other end on the movable jaw, and squeeze the handle.
