Author Topic: Frame Drift? Dave Bird Jedi Master Film Handler Posts: 777 From: Perth, Ontario, Canada Registered: Jun 2000 posted 02-01-2001 09:17 AM                        What I should do is print this thread off and go looking for all this stuff. The only thing with a spring under it is the PA-1570. Other than that, just a round disc on the other (gear) side. I take it that you can put a spring on this side also. 30 years + at the drive-in could have worn the existing ones down, however it seems like it's okay if I start in the middle. Perhaps I'll install them anyway, does anyone have a part number, or are they shown on the old parts manual?  |  IP: Logged Paul G.

Thanks for the tip. Much appreciated. - Paul  |  IP: Logged Paul G.

Try different settings of the frame knob. It might help you isolate what is going wrong. There may also be a gear or bearing going south on you. I would also try the run-down thing without the intermittent in the projector. But first, check to make sure the flywheel on the intermittent is tight. It almost sounds like a loose flywheel.  |  IP: Logged
