It'll sure take 'em off quick, around that pulley. ------------------ Better Projection Pays!  |  IP: Logged Scott Norwood Film God Posts: 8146 From: Boston, MA.

(see pic below) The belt can be something from an auto-parts store and the motor can be something pretty standard. The motor on the bench in the picture is a 1/2 horsepower Westinghouse (?) motor. I don't remember the diameter of the pulleys, but it would do about 1000' per minute, which was a bit fast for print inspection. I'm told that someone dug up a variable speed control for this, but I'm not sure what type of control it was.  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 09-26-2000 03:26 PM                        The pinch points around the pulleys are something I'm sure OSHA wouldn't approve of today. Ouch! Be careful, and DON'T wear a tie or long hair in the booth. 1/2 horsepower is overkill. A smaller, variable speed drive motor would be a much better choice. ------------------ John P.

You may not be able to see it as it goes around. Possibly biting some part of your hands off. These are adaquate rewinds but just not the safest ones.

USA (1774.21 miles northeast of Dallas) Registered: Jun 99 posted 09-26-2000 08:52 PM                        Yes, the problem with the fixed-speed motor was that you had to crank the right-hand reel by hand in order to get it up to speed before flipping the motor switch in order to avoid breaking (acetate) or severely mangling (ESTAR) the film. I found a better (or at least bigger) picture of the same rewind bench in case anyone cares (below). Incidentally, if anyone has a pair of these rewinds for sale cheaply, let me know. I'd like to be able to at least accommodate 1/2"-shaft reels at home and nearly fainted when I saw the price on 1/2" shaft adapters for Neumade rewinds...  |  IP: Logged john bishop Film Handler Posts: 14 From: howell,nj USA Registered: Jun 99 posted 09-27-2000 04:56 PM                     thanks for all the help guys! i'll keep searching for a motor. i emailed iceco but haven't heard back yet. now for another question, what's with 1/2" and 5/16" shafts?!?! isn't most of the weight of the reel taken up by the drive pins? i can put a 1/2" 6k reel on a 5/16th 6k arm with no problem, so why would i need a 1/2" adapter(which i just bought,anyway)? what i'm trying to say is, the shaft almost seems to be inconsequential, the pins seem to be doing the real work.(or am i totally in the dark on this?)......john ps--scott--the rewinds in that pic are the same exact ones i have----john  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 09-28-2000 04:55 AM                        John: Large reels often use a 1/2 inch spindle hole, rather than the 5/16 inch spindle hole and keyway. Obviously, the spindle should fit the hole. The shaft is what actually centers the reel, so the reel will likely be off center and vibrate if not mounted on the correct spindle. ------------------ John P.
