Author Topic: ELH lamp on Simplex Craig Hardy Film Handler Posts: 28 From: Barrington, New Hampshire USA Registered: Oct 2018 posted 10-29-2018 01:29 AM                     Jim wanted to see pic of my rig, so will attach photo  |  IP: Logged Steve Kraus Film God Posts: 4094 From: Chicago, IL, USA Registered: May 2000 posted 10-29-2018 08:00 AM                    Looks like a nice solution! Lest anyone be confused, the bowl is simply the cover and cooling fan support and not a reflector as the ELH (120V 300W halogen) provides its own. Also, the bowl is centered on the shutter housing and of course the optical center is quite a bit towards the operator from that as Craig noted in the photo. Craig, did you make your bulb socket adjustable so you could tweak the position?  |  IP: Logged Craig Hardy Film Handler Posts: 28 From: Barrington, New Hampshire USA Registered: Oct 2018 posted 10-29-2018 11:38 AM                     Steve, I positioned it on optical center and light is even brightness corner to corner on screen. Scrounged the lamp sockets from "parts" slide projectors. I chose the ELH because it's most common one used in slide projectors i.e. Kodak Carousels, and our movies are same film size. The ELH is I think 6" focal length reflector.  |  IP: Logged Mike Croaro Master Film Handler Posts: 394 From: Millbrae, CA Registered: Apr 2005 posted 10-29-2018 04:35 PM                     How large of an image can you project?

Thanks for posting the picture. I can't tell for sure from that angle, but that projector head looks like a Simplex "Standard" from the 1930's. There were still a lot of them around when I was running film in the 1970's. Built well. Ran "forever" if you kept them reasonably clean & lubricated. (I always used the "Simplex Oil" since that's what was in the booth)  |  IP: Logged Alan Gouger Jedi Master Film Handler Posts: 501 From: Bradenton, FL, USA Registered: Jul 2000 posted 10-29-2018 06:08 PM                        Craig are you using any kind of a condenser lens before the lamp. Do you have any screen shots. Thank you for sharing.  |  IP: Logged Craig Hardy Film Handler Posts: 28 From: Barrington, New Hampshire USA Registered: Oct 2018 posted 10-29-2018 07:36 PM                     Mike, 8 ft wide image is bright. Haven't thrown it on anything bigger cuz haven't had occasion to. If switch to 'scope I'll probably overshoot screen onto white wall, but haven't had occasion to do that yet. I built the home theatre with soundproof booth mainly for screening home movies and my library of 75 or so classic features like "Casablanca", etc. on 16mm. Ten years later I got into 35 helping friend run the old IOKA in Exeter, NH with Brenkert BX80's and Ashcroft lamps. THAT got me into 35mm, Then I scrounged the Supers and set up for outside screening. This pair of Standard Simplex's are mounted on dollys and one is in the little booth just to have capability to screen 35 indoors. Jim, I'm posting pics from all sides. These came from Hampton Casino in Hampton, NH when Sharky stopped running movies there. As mentioned in another post, the jerk electricians tossed them out of booth, about 14ft drop onto a wooden floor and they survived! They run real sweet and quiet, and thanks to you folk's advice, with proper lubrication that will continue...  |  IP: Logged
