Posts: 4247 From: Bloomington, IN, USA Registered: Feb 2002 posted 07-20-2003 03:58 PM                     How the HECK do you align the lenses on a Prevost P-93 so that they both centre the image on-screen?  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 07-20-2003 04:14 PM                     I assume one lens is lineing up? On the P55's I used to put a layer of film on one side of the lens as I slid it into the turret to shim it over estar film makes good stable shims  |  IP: Logged German Marin Expert Film Handler Posts: 227 From: Verbania (VB), Italy Registered: Jul 2001 posted 07-20-2003 05:20 PM                     Try aligning here, there's a flat and scope one. I've done this with an align-O-tron pointing back to lamphouse and I centered each lens to apperture plate and lamphouse mirror. Then turn the align-O-tron to screen to center the projector.  |  IP: Logged Manny Knowles "What are these things and WHY are they BLUE???"

I guess I will have to go with the "shims" as Gord suggests.  |  IP: Logged
