Author Topic: Philips FP3 or Marin MP30 Julian Baquero Film Handler Posts: 18 From: Bogota D.C., Colombia Registered: Aug 2011 posted 09-27-2011 06:30 PM                        Hi Damien thanks for the information and offering the schematics, I still don't have the projector, but if it becomes a reality I will let you know and I will accept the scans of the drawings. Correct me if I am wrong, regulators are only needed for DC, halogen lamps are AC so they would only need an AC transformer if they are something different from 120V. What is the use of the framing lamp? super 8 and 16mm projectors don't use them. I saw the bulbs that this projectors have and they don't have any mirror inside, what is the effect of this if the original mirror was removed as Emiel noted.  |  IP: Logged Damien Taylor Master Film Handler Posts: 493 From: Perth, Western Australia Registered: Apr 2007 posted 09-28-2011 03:24 AM                     Yeah the only DC thing is the exciter and you can get a power supply for those pretty cheap. The one in the original power supplies used a rectifier valve which would probably be dead by now anyway. The framing lamp and pilot lamp have a pretty simple purpose. The Pilot lamp, which is contained in that housing above the large sprocket that comes all the way out. It simply lets you know that the power supply is connected and working, and gives a little bit of light to work by. The framing lamp is right inside the gate and it's purpose is so you can thread the film with a dull light as the main lamp will not turn on without the motor running.  |  IP: Logged Emiel De Jong Film Handler Posts: 48 From: Geldrop The Netherlands Registered: Mar 2007 posted 09-28-2011 06:42 AM                     As I understand, they deleted the hollow mirror already in 1955, because it was possible to shorten the lamp's life dramatically with a badly adjusted mirror. I guess that the extra light output such a mirror gave was just not worth the trouble. What the effect is with other lamps than the intended original I don't know but I think as long as the condensor lenses (between lamp and film) are there you're fine.  |  IP: Logged Damien Taylor Master Film Handler Posts: 493 From: Perth, Western Australia Registered: Apr 2007 posted 09-28-2011 08:28 AM                     As far as I can tell there were many revisions of this machine, this is what my data plate says; Type No. 8710 - 05 Serial No. 8.2336 I guess that means that mine is a Mk V or something. I couldn't tell you what the differences were. I know that early machines had a fixed aperture and a wooden gate. I really wish there was more info out there on the internet about these machines.  |  IP: Logged Ian Parfrey Phenomenal Film Handler Posts: 1049 From: Imbil Australia 26 deg 27' 42.66" S 152 deg 42' 23.40" E Registered: Feb 2009 posted 09-28-2011 02:30 PM                     I have a design question about these machines and I'd like to get any opinions I can on this. From a purely 'film-friendly' perspective, these projectors appear to be rather poorly designed. By this I am referring to the use of the two film-guiding rails seen above the gate and just post the intermittent. I can understand that the use of the single sprocket would greatly simplify the gearing/belting required to make the machine work, but to my eyes this basic design would place the film at greater risk of damage due to rail wear than would multi-sprocket designs that do not feature these rails. I can see many similarities to the 16mm BTH 450 in regards to the use of these rails and wonder if I am being overly critical of this design. I will admit that I have neither seen or used either of these projectors, but from my admittedly limited point of view, they appear to be rather unkind to film. Is this a fair critique of these machines?  |  IP: Logged Damien Taylor Master Film Handler Posts: 493 From: Perth, Western Australia Registered: Apr 2007 posted 09-28-2011 05:40 PM                     The rail thing directly above the gate is a pileup shutdown switch, the film never runs on it. There is a rail directly behind the Philips logo, but I've never seen them worn, much less harming prints.  |  IP: Logged
