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.

Some have a crank arm on both ends, allowing the film to be wound in either direction. Typically the crank can be disengaged by pulling it towards the operator, separating the crank gear from the shaft gear.

Typically the crank can be disengaged by pulling it towards the operator, separating the crank gear from the shaft gear. While cranking, maintain gentle pressure in the direction of the reel in order to keep the gears engaged. | ||
Hand-crank rewinds may be screwed or bolted onto a rewind table, or they may be portable clamp-on models. | Hand-crank rewinds may be screwed or bolted onto a rewind table, or they may be portable clamp-on models. | ||
