A '''rewind bench''' or '''rewind table''' is a workspace for rewinding, inspecting, and repairing film. Rewind benches come in many forms, ranging from a pair of hand-crank rewinds clamped to a portable table to purpose-built systems with more advanced features. At the bare minimum, a rewind table should have a pair of rewinds, a light table (either built-in or portable), and room for a [[splicer]] and other [[inspection]] tools. | A '''rewind bench''' or '''rewind table''' is a workspace for rewinding, inspecting, and repairing film.

[[File:Neumade Dynamic X-3 brake mechanism.JPG|right|thumb|300px|A Neumade Dynamic X-3 brake mechanism. The brake paddle presses a U-shaped piece of felt against a collar on the end of the spindle shaft (not pictured) to apply hold-back tension. For hands-free use, a bolt can passed through the hole in the center of the paddle and the table, with a wingnut on the top of the bolt to regulate brake pressure.]] | |||
The most basic rewinds consist of a geared end that is manually driven by a hand crank and a dummy end on which the feed tension is regulated by applying friction to the reel by hand. The dummy end may also have a hand brake or another mechanism to regulate feed tension. The tension settings on hand-crank rewinds can be very rudimentary, such as a spring providing metal-on-metal friction on the back of the feed spindle or a brake paddle with a small piece of leather that is pressed against a wheel on the feed shaft. In many cases more satisfactory results can be achieved by applying friction to the feed reel by hand. | The most basic rewinds consist of a geared end that is manually driven by a hand crank and a dummy end on which the feed tension is regulated by applying friction to the reel by hand.

On many rewind tables, the drive end is motorized. Ideally, the motor should be variable speed and capable of slowly ramping up and ramping down. Single speed motors WILL damage film and should never be used. The motor speed should always be gradually increased and decreased to be gentle on the film. | On many rewind tables, the drive end is motorized.
