Author Topic: DTS Sound Drum "Dragging" Jim Cassedy Phenomenal Film Handler Posts: 1661 From: San Francisco, CA Registered: Dec 2006 posted 08-31-2009 12:56 PM                     Yesterday, I noticed the sound drum on one of my DTS readers was "dragging" slightly. Not enough to damage the film, or cause timecode errors long enough to dump to analog, but it's just not turning as freely as all my other readers. It seems to be slightly 'gummed up'. It has one of those "do not adjust" stickers on the bracket so I'm curious- - Can that bracket that supports the axle the DTS sound drum turns on be dissassembeled so I can clean and/or lube as necessary without throwing the reader out of alignment?  |  IP: Logged Jarret Chessell Master Film Handler Posts: 288 From: London, Ontario, Canada Registered: Jan 2009 posted 08-31-2009 01:58 PM                     right under that little sticker you aren't suppose to remove is a flat had screw. That screw controls the alignment of the reader. You would need to remove it to take it apart. My experience is that once you move that screw the reader will never be quite the same again, it takes time to tweak it in so that it reads on all film prints again (it'll be perfect on one and might have troubles on the next). Gordon knows quite a bit about working on them. He'd have some good pointers on working on it for sure.  |  IP: Logged John Hawkinson Film God Posts: 2273 From: Cambridge, MA, USA Registered: Feb 2002 posted 08-31-2009 02:26 PM                     Remember that there is a small vertical allen set screw on that adjustment screw -- the screw head is on the underside of things, so it's easy to miss. Anyhow, don't try turning the adjustment screw without loosening the setscrew... --jhawk  |  IP: Logged Jarret Chessell Master Film Handler Posts: 288 From: London, Ontario, Canada Registered: Jan 2009 posted 08-31-2009 03:02 PM                     oh yeah, and don't forget to remove the set screw.  |  IP: Logged
