The Eiki EX6000 handles 6000 ft reels and uses no clutches on reel drives. On take up the reel goes directly on the motor shaft and on supply there is a belt from motor to the reel shaft but no clutches. Hold back on foreward and rewind is achieved by application of weak but adequate opposite direction drive. The gummy belts used in this machine can be replaced by Roundthane made endless byheat fusing and are available from any competent industrial belting supply house. These machines ar ca. 1981 & later.

Thanks for all this great information, I'm in the process of putting some kind of rig like this together - I'm shopping for the right motor for the take-up. I was wondering what the rpm should be- this motor is 4rpm which I think will be too slow (maybe the correct speed when the reel is full, but not when the feature is starting):

- and it would be great to find a motor that I could vary the voltage on, to vary the speed. Correct me if I'm wrong, but if I do that on this synchronous motor I will burn it out.

Following Steve's picture as a starting point, I cobbled together this long-play rig for the yearly "Movie Nite" that I put on as a fundraiser at my son's Gradeschool. Last year I did a changeover with two Pageants, but the image was sort of dim. On Ebay I found a reasonably priced Pageant with a xenon Arc, but since I didn't have two, this necessitated the long-play system. The only difficult part was getting the right combination of speed and torque for the take-up motor. After trying many variations and motors, I finally used a stepper motor with an animation camera control (I'm an animator). I hadn't yet taped down the cords when this first picture was taken:

We showed "Looney Tunes: Back In Action" on a very large homemade screen and we had a great turn out, made a healthy profit for the PTA fund. The picture below was taken early in the evening, and by the time we started the show it was standing room only.

We put on this show in February and next year the PTA is talking about doing two movie events during the school year. Thanks for the help!
