hi folks--i've just received my first pair of 6000ft rewinds. they are made by the Edward Wolk Company. one of the rewinds has a 10 1/2" pulley for the rewind belt. does anyone know of a good place to get the belt and a rewind motor? are there such things as variable speed rewind motors? this is all new to me, thanks for any help you can provide!! john

Watch out for your fingers on that one! It'll sure take 'em off quick, around that pulley.

Is this the type of rewinds that you're using? (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.

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.

Personally, I'd take the knob off too. 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.

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...

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

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.
