Author Topic: Framing handle "set," but still out of frame Ken Lackner Phenomenal Film Handler Posts: 1907 From: Atlanta, GA, USA Registered: Sep 2001 posted 02-26-2004 03:09 PM                     I successfully centered all the framing knobs on the Simplexes yseterday. Is there anything I can do to center the knobs on the Centurys? BTW, we have top masking in our smaller houses, but all the projectors have turrets. There is no need to adjust the framing after a format change. I have never had do do that at any theater I've worked at. Each lens has always been centered correctly.  |  IP: Logged System Notices Forum Watchdog / Soup Nazi Posts: 215 Registered: Apr 2004 posted 03-03-2008 08:32 PM                 It has been 1467 days since the last post.  |  IP: Logged Jeremy Weigel Phenomenal Film Handler Posts: 1062 From: Edmond, OK, USA Registered: Mar 2007 posted 03-03-2008 08:32 PM                     "Bump" What is the corect position of the intermiitent assembly to be centered with the framing knob at horizontal? I thought that I read somewhere either here or some other literature the index mark on the outer bearing support should be near the 12 o'clock position with the framing knob horizontal.? Running 1060's.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 03-03-2008 08:46 PM                     ..what I do with all "XL" based Simplexes - have the INT collar line close to vertical - that way the assembly get's the best oiling from the funnel delivery in the transmission case ...  |  IP: Logged Jeremy Weigel Phenomenal Film Handler Posts: 1062 From: Edmond, OK, USA Registered: Mar 2007 posted 03-03-2008 09:03 PM                     Ah maybe that's where I got that from. I just wanted to make sure I have the intermittent set correctly before I start cutting new plates.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 03-03-2008 10:59 PM                     um, before you get into that project, do the 35PA (RP-40) loop test first to see if machine is level and center before you begin to get crazy with the files on new aperture plates.  |  IP: Logged Jeremy Weigel Phenomenal Film Handler Posts: 1062 From: Edmond, OK, USA Registered: Mar 2007 posted 03-04-2008 12:12 AM                     Yep already done. I actually had to do a complete re-alignment of the gate on these. After I got things back to factory specs using the 3.112 gauge to align the studio guide and the 77 gauge to align the lat guides and intermittent sproket the film had shifted enough to expose the DTS time code and adjusting the lens gave too much bleed over on the right side masking, so... time for new plates. I was all set to cut new plates when I noticed that one of the 2 machines had the index mark almost at 9 o'clock position with framing knob set at horizontal. This doesn't leave much rotation to adjust for the ocassionally rare mis-thread. So anyway, something clicked in the back of my memory that the index mark is typically set to near 12 o'clock with framing knob at horizontal (which the other machine is). All this also made sense of why ocassionally over the 7 years we've run this theatre, a projectionist would call and tell me that they had to stop the film to correct mis-threading rather than being able to correct it with the framing knob. I also replaced the 2 weak springs that lock the turret in position with one single spring strong enough to "bottom out" the pin every time so the lens lands in the same vertical position when rotated.  |  IP: Logged Kenneth Wuepper Phenomenal Film Handler Posts: 1026 From: Saginaw, MI, USA Registered: Feb 2002 posted 03-04-2008 06:20 AM                     Jeremy, On some machines it is possible to press the framing knob toward the machine and disengage the gear inside. This allows the operator to set the position of the knob without changing the setting of the framing mechanism. In machines like these an operator may change the position of the word "FRAME" to cover up evidence of a mis-frame. I have used the "pin hole" aperture plate to locate the center of the aperture before making other adjustments. The pin hole plate is also very useful when adjusting the focus of the lamp without the projection lens in place. An image of the reflector can be seen on the port glass or a paper over the window.
