Author Topic: Can aperture plates be reused? Gary A. Hoselton Film Handler Posts: 59 From: Portland OR U.S.A. Registered: Nov 2005 posted 06-18-2011 03:15 PM                     Is there a practical way to infill a filed aperture plate, so it can be refiled for new application? Thinking of Simplex XL, and the economics involved.  |  IP: Logged Aaron Mehocic Jedi Master Film Handler Posts: 804 From: New Castle, PA, USA Registered: Jun 99 posted 06-18-2011 04:07 PM                     Some of our in-house guys will save aperture plates in the event that down the road additional filing will get them back on screen in a different venue. I always considered it rather cheesy, but its not my call. A manager here on the forums purchased some brand new plates last year and filed them to fit the poorly refurbished ones. The screen images looks a lot better now than it did then.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 06-18-2011 04:44 PM                     XL plates are not that expensive (unless, you have a PR-1050 with the slider plate that works with the TU-2000 turret assembly, then those can be a bit more..), yet if one is good with brazing, one can braze on some more brass strips to the opening for recutting. But, there is a way, if the cuts aren't too far cut out, and that is to gradually "push" the brass towards the opening, tapping a hammer on end of a flat end punch with the plate on a bench vise or anvil to where there is enough brass pushed over to do a recut. -Monte  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 06-18-2011 08:27 PM                        Compared to other costs, this one is really insignificant.(Except on Christie projectors.) I do keep old plates in case I can use one up where I need a larger hole. (Widths larger then 0.825 are already too big!)

The DP-70 plate is about 250 USD now... . I think you could have a batch produced by a metal stamping facility for way less than that!  |  IP: Logged
