Author Topic: Sloppy Potts Platter Takeup Cory Renkenberger Film Handler Posts: 2 From: Kendallville, IN United States Registered: Dec 2008 posted 12-18-2008 01:03 PM                     I have been on hiatus from our theatre equipment for several months, and the owner recently asked me to investigate a platter take-up problem. Both platters that are controlled by the same Variable Autotransformer have been winding the film VERY loosely when they are on the Take-Up mode. I have replaced drive belts, checked platter speed, and I am wondering if the problem lies in the Variable Autotransformer itself? I have never encountered this problem with this platter, and we have been using it since 1984. Other than that it runs well. Any suggestions on how to increase the "takeup torque" on this unit?  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 12-18-2008 01:08 PM                     (bad answer...)  |  IP: Logged Mitchell Dvoskin Phenomenal Film Handler Posts: 1869 From: West Milford, NJ, USA Registered: Jan 2001 posted 12-18-2008 01:10 PM                     Eh? The weight of the yoyo keeps the film tight. It is not really adjustable. However, I have seen the yoyo stick and not float freely, do to misaligned rods or dirty slide rollers. When this happens, it does not gradually drop down with the film, causing the takeup to run slower than it should.  |  IP: Logged Joe Redifer You need a beating today Posts: 12859 From: Denver, Colorado Registered: May 99 posted 12-18-2008 01:36 PM                        "Yo yo", LOL. Anyway, check the roller spindles on the take-up path of the variac. It is likely that one of them is bent.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 12-18-2008 01:48 PM                     Yea, I call it either the "W" or the "Trombone" ... but heard the term "Yo-yo" many times....  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 12-18-2008 02:29 PM                        Can I assume this is a Strong/Potts platter?
