Author Topic: Adjusting take-up tension on old red Speco platter Dan Chilton Expert Film Handler Posts: 191 From: Springfield, MO Registered: Mar 2004 posted 11-29-2008 06:49 PM                        Is there a way to adjust how high the accumulator roller climbs after you've threaded up? We're using old red Speco platters with those awesomely flimsy roller rods at the top of the platter, and every time we thread up, it pulls the accumulator to the stopping point at the top of the tree and puts a lot of stress on the rods. Is there any way to prevent the accumulator going up so high, so should I just modify it with compression springs? I certainly don't want the tension transferring through to my brand new cue detectors.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 11-29-2008 09:16 PM                     ..thought about adjusting the twist rod that goes to the variac in the bottom so it would close earlier?  |  IP: Logged Dan Chilton Expert Film Handler Posts: 191 From: Springfield, MO Registered: Mar 2004 posted 11-29-2008 09:59 PM                        How do I make that adjustment, Monte? The Specos are new to me!  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 11-30-2008 02:45 AM                     Okey, I jumped ahead of you for a bit there, sorry, didn't know that you had no experience with Drive-In (SPECO) LP-270 platters (where the decks were actual K-Mart picnic tables..lol) In my days of running LP-270's: When you thread your platter, keep the yellow takeup button in the control box off until the "trombone" roller, that is on the spiral shaft have reached end of the twist on the rotating shaft when you manually tighten up the film on the takeup platter by hand. Then, after this is done THEN is when you depress the takeup button on the control box attached to the tower so the Yellow light is on (if the bulbs under the switches still work...) This will keep those roller spindles from bending down when that trombone goes above the twist on that rotating shaft. Hope this helps. good luck - Monte  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 11-30-2008 03:03 AM                     Or when you pull takeup tension at the projector you can simply pull MORE film than you are currently doing. Pull a good 2-3 feet's worth...wait 3-4 seconds...then release the excess.  |  IP: Logged
