Author Topic: Potts platter problems Mike Frese Master Film Handler Posts: 465 From: Holts Summit, MO Registered: Jun 2007 posted 02-17-2012 08:26 PM                        Model a-3 I was having trouble on rewind. I noticed a dead spot when the trolley/w/you-yo was right where the pin goes in for threading. I removed the variac and noticed that a 1/2" or so of the metal on the underside ofthe rotor was gone. The little button had broken off on the brass tab as well. So I took the variac from the MUT (just used it yesterday) put it in the control box. I can't get the platters to spin at all (trying o set the electric zero). I have power through both fuses and though the shut off switch. Help!  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 02-18-2012 12:29 AM                     Need to adjust the switch down there at the variac to where the switch (wires should be on the outside terminals of the switch) that the tang goes outward and closes connnection when the variac arm is about 10 degrees open. If you have another platter, check its setting to the one you're working on.  |  IP: Logged Mike Frese Master Film Handler Posts: 465 From: Holts Summit, MO Registered: Jun 2007 posted 02-18-2012 09:44 AM                        Monte, Are you talking about the switch that shuts the motors off when the w/yo-yo/trolley goes to the bottom? That is open and power is going through the switch when the w is up off the bottom.  |  IP: Logged
