Author Topic: Kelmar rewind bench help - cinching on film Mike Heenan Phenomenal Film Handler Posts: 1896 From: Scottsdale, AZ, USA Registered: Mar 2000 posted 04-23-2014 07:26 PM                     My Kelmar table has been cinching acetate film lately. The tension is let out all the way, and the feed reels are sometimes loose wound but usually tight. What usually happens is the motor will start "groaning" or grinding, and will clicking as the take up reel is getting full and will start cinching so that when it finishes, the middle is loose and the outer part is tight. At other times, I'll get a tight core, but it causes cinching on the feed reel. Any suggestions? Thanks!  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 04-24-2014 01:21 AM                     I wouldn't blame the table, but more the film,esp where it's acetate, and we all know that acetate gets a slight bit of a lateral curl in it when the stuff ages due to slight shrinkage. Wind the film opposite then - If you're doing emulsion out, wind it emulsion in to counter-act the curl. -Monte  |  IP: Logged Randy Stankey Film God Posts: 6539 From: Erie, Pennsylvania Registered: Jun 99 posted 04-24-2014 02:24 AM                     Agreed. When film doesn't behave the way you want it to, try winding it in the opposite orientation in the reel or platter.  |  IP: Logged Manny Knowles "What are these things and WHY are they BLUE???"

You might need to replace or re-seat one (or both) of them.  |  IP: Logged Mike Heenan Phenomenal Film Handler Posts: 1896 From: Scottsdale, AZ, USA Registered: Mar 2000 posted 04-24-2014 07:27 PM                     I did the winding opposite way trick and that seemed to have worked on a couple reels. I like to store acetate emulsion in as that's what Kodak recommends. Some polyester reels I rewound didn't have any issues. I should probably have the brushes looked at as well, thanks!  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 04-25-2014 04:53 PM                     We have a large stock of Kelmar rewinders just in case....  |  IP: Logged
