Author Topic: Cinemeccanica platter mod Ron Curran Jedi Master Film Handler Posts: 504 From: Springwood NSW Australia Registered: Feb 2006 posted 03-14-2010 12:02 AM                        We got tired of dismantling the cover and reaching inaccessible pots to adjust the speed of our platter. So we wired new pots with shafts and knobs. I know that manufacturers design equipment to keep fiddlers at bay but we must also protect our projectionists from the 220 Volts that lurk under that cover.  |  IP: Logged Ian Parfrey Phenomenal Film Handler Posts: 1049 From: Imbil Australia 26 deg 27' 42.66" S 152 deg 42' 23.40" E Registered: Feb 2009 posted 03-14-2010 01:00 AM                     Ron. I'm interested to know why you have to constantly adjust the speeds. Is it due to power fluctuations or wear on the mechanisms?  |  IP: Logged Phil Blake Jedi Master Film Handler Posts: 558 From: esperance western australia Registered: Nov 2003 posted 03-14-2010 09:52 AM                        Ian I have found our Cinemeccanica platters to be very sensitive to heat. few weeks ago now we had a 49C day and all my payout modules were creeping. adjusted them back , next day was cooler and they all were lagging.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 03-14-2010 02:09 PM                     Exactly. They're EXTREMELY sensitive to temperature. A variation of 2°C could be fatal for your print. The platter will start spinning slowly when in stop position and if you do not realize in time you'll have a nice brain wrap to handle with. I don't have any suggestion. Luckily in my projection booth the temperature was constant for the most of the time.  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 03-14-2010 02:40 PM                        Whatever is temp. sensitive should have a small heater (light bulb) next to it to permit one constant temperature. If light sensitive, a large resistor will do.

When access to control was difficult they needed regular adjustment. Now we can adjust easily they are fairly stable. I have attached a paper flap over the controls saying "Adjust only if absolutely necessary. Remember, only 1 or 2 mm is required" just in case the temptation is too great for one of our projectionists.  |  IP: Logged
