Author Topic: Another Strange Noise Robert E. Allen Phenomenal Film Handler Posts: 1078 From: Checotah, Oklahoma Registered: Jul 2002 posted 02-12-2014 01:53 PM                     One of the top platters on my AW 3 makes a noise similar to the playing card in the bicycle spokes when I turn it by hand when threading. Do I need to be concerned?  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 02-12-2014 02:31 PM                     That all depends on how much longer until you install digital. Seriously though, hold the motor away from the edge of the deck and spin it. Sound still there? Remove the brain. Sound still there?  |  IP: Logged Matthew Ortado Film Handler Posts: 20 From: Halethorpe, MD, USA Registered: Jan 2010 posted 02-12-2014 07:16 PM                     Check the drive tire. If it is a white one, it could be leaving pieces of the tire on the deck. I have had to clean the white material off of many platter decks.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

Prop the motor off the deck and spin it either by hand or via the make up table. One has to isolate just where the noise is actually coming from.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 02-15-2014 08:50 PM                     Yes, just brush noise or a badly worn commutator or both. You could swap the top and bottom motors around since it seems the bottom gets used much less. The top and center get used the most. Just re-check the timing after you move them.  |  IP: Logged
