Author Topic: Platter extension rod lubrication Alex Grueneberg Expert Film Handler Posts: 125 From: Chicago, IL Registered: Aug 2004 posted 11-10-2005 06:36 AM                        I have two Potts 5 deck platters. Currently I am having an issue with the top 3 platters (or top 2 depending which side the middle platter is set to) on each 5 deck. The problem is the take up assembly (or snake) seems to lower to slow due to poor lubrication on the take up extension rod and slide tube. This causes the motor to rev up very high at the end of shows, and makes for an inaccurate rewind speed. It also scares my manager who sometimes has to thread shows during the week. I'm curious as to what lubricant if any is safe to use on the extension rod and slide tube? Any input is much appreciated.  |  IP: Logged Thomas Dieter Expert Film Handler Posts: 234 From: Yakima, WA Registered: Jun 2004 posted 11-10-2005 07:45 AM                     I personally have never dealt with any 5 deck platters, but I have worked with the Potts Alpha platters and CFS Super Platters. Both have essentially the same take up setup cept the CFS only goes down once making an "N" look, the Potts platters dip down twice, making the look of an "M" or "W". When ever I had a problem, I usually made sure that the slide rails were spaced properly, and were clean of any dirt or sticky residue. As for lubracation, I can't help there, but you might check that out if you haven't.  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 11-10-2005 08:16 AM                        First of all, make sure these items are not bent, If lubrication is required use a teflon or silicon based lubricant commonly found at a locksmith. (Regular oil, including projector oil, will gum up over time) If oil was used in the past WD40 will degunk what was done earlier.

Monte, is there a possibility for repair? Or does this need to be replaced. Thanks.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 11-15-2005 03:20 PM                     quote: Alex Grueneberg Monte, is there a possibility for repair?

I'd check the action inside the variac to see if anything isn't binding up to cause the accumulator - just unplug the platter before taking that cover off.  |  IP: Logged
