Greetings everyone!
I could not find any old threads on this subject so I wanted see if anyone has experienced this problem besides me.

I have an Elmo 1200HD and do you have to match the take-up reel size with the film reel size you are running?

I use an Elmo 800ft take-up reel and sometimes when I rewind the film back on to a 400ft reel the film toward the end starts to rewind lopsided? I then have to stop the film and use my hand crank rewinders. Has this happened to anyone?

If I run a 400ft short should I be using then a 400ft take-up reel?

I did a test with a 400ft film and used a bonum 600ft take-up reel and it seemed to rewind the film a lot better. It seemed to rewind the film a lot faster too!
Any information on the subject would be greatly appreciated!
Thank you,

I use the 1200' take up reel for everything, so I do not have the same problem. Not on the ST-1200D MO, ST-1200HD MO, GS-800, GS-1200. GS-800 is 800' reel of course, but use the same reel for everything

Hi Vidar,

Thank you for your reply!
I had an Elmo ST-800 which I sold and I always used the 800ft take-up reel with it so it makes sense now for me to use the Elmo 1200ft take-up reel with my 1200HD. I will try it and see if that resolves the problem.

Thanks,
Roger

Hi Roger,

You are doing the right thing in running a larger take up reel with you film. When you go to rewind, give it some slack by manually winding it back a few feet with a tight wind. THen hit the rewind switch while you apply gentle pressure (with your finger) on the take up reel as it is winding whenever the film seems to bounce around.

The print could be shrunken so that when it rewinds, there are pockets of air and film that are not tightly wound that causes a loss in even winding. Either way, if it could be a belt change need as well, sometimes it's best to manually wind the film back on rewinds to conserve wear and tear on the projector.

Hi Gerald,
Thank you for your excellent advise! Also when I rewind the film using my hand rewinders I set the brake not to tight the film rewinds really tight back on the reel so is alright to have the film too tight on the reel? The projector rewinds the film not as s tight as the rewinders do. I don't want to do any damage to the film with the my hand rewinders.
Thanks,
Roger

PS Oh I will send you a PM later on "our daily bread"

From the research that I've done, a tight wind should be only okay if it's a polyester print and in regular rotation during screenings. Acetate prints need a little air, so do some polyester stocks so in my opinion, a tight wind is okay if stored as an open reel only.

But, be careful winding the film too tightly if it goes into a case, clamshell or can only to archive into your library. Also, a tight wind on a print that is shrunken could be okay (and helpful with regard to pliability) if archived tails out, on an "s" wind.
