If you picked a Bauer U2 to be along with this, then you'd would have quite the duo there. Did you have to do some sort of beam spreading techniques from that little lamphouse to fill that 70mm aperture with your unit there? Great setup anywhos and congrats! -Monte  |  IP: Logged Damien Taylor Master Film Handler Posts: 493 From: Perth, Western Australia Registered: Apr 2007 posted 08-08-2008 03:06 AM                     I have a TQ1 with a broken worm, and another similar vintage B&H with a good worm I was going to canabilise.

That is why the lamptable is different, it was a small lamphouse but it can hold a bigger one. After mounting shutter,dowser and other stuff it was, together with the one of Tom Beetz, I install them in he MIDI Theater in Tilburg which is, sadly, now closed also.

Shipping crates still exist in Louisville KY from 1956. The European crates are almost fine furniture, the U.S. crates look like pallets.

YEP! The first ones were made by American Ooptical and the later ones by Ballantyne... before they were sucked up by Wrong International. If anyone needs any DP-70 parts just drop me a note... we have EVERYTHING in stock!

I currently use the old Orcon 1000B 700w Zenon and (just) about get away with a Beam Spreader and defocus the Lamp for a 70mm screen, my screen is only about 8ft at home. quote: Damien Taylor have a TQ1 with a broken worm, and another similar vintage B&H with a good worm I was going to canabilise.

Yes they are, I have two of them and use quite a lot in the Winter for 16mm Race Nights, both had new Worm Gears when I bought them. There are several people in the UK would still repair these, I would change the old A1/258 for a A1/259 Lamp and base.  |  IP: Logged Scott Norwood Film God Posts: 8146 From: Boston, MA.

Is this something homemade, or is (was?) it a commercially available product? Does it work reliably?  |  IP: Logged Ben Wales Jedi Master Film Handler Posts: 602 From: Southampton.

That was made in the UK by Bell & Howell for the TQ1 (656) Projector range. The back feet of the projector would seat on the base of the long play spool arm centre post and another arm would swing down and clamped up on the front feed arm of the projector. The Take-up was a slipping belt arrangement as the spool got heavier the Torque take-up would be higher.  |  IP: Logged Sean Weitzel Jedi Master Film Handler Posts: 619 From: Vacaville, CA (1790 miles west of Rockwall) Registered: Dec 1999 posted 08-13-2008 04:52 PM                     I'm planning to use an ORC M1000 behind a Century JJ very soon here for my home screening room. Can anyone tell me where I can buy a beam spreader that will work with this kind of setup for 70mm? I'm looking at about a 19 foot throw from lens to screen.  |  IP: Logged Don Furr Jedi Master Film Handler Posts: 509 From: Sun City, Ca USA Registered: Nov 2002 posted 08-13-2008 05:39 PM                     Sean I tried using a 1K lamp behind my V8 35/70 and it just wouldn't cut it for a 22 foot throw. I had to go up to a 1600 watt lamp. That made all the difference.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 08-13-2008 06:41 PM                     Kinda wondering if a spreader lens from an old Christie CH-10/20 console snood would work with these small ORC lamphouses.  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 08-13-2008 09:30 PM                        You may not need a beam spreader for the ORC 1000 if you just remove the condensing les and adjust the working distance some. Expect to pay $800+ for a beam spreader.

I'm just a little old film collector who has an eclectic hobby I think I'll have to try it out first and see what the results are before I decide if I need different hardware. Thanks for the advice.  |  IP: Logged Scott Norwood Film God Posts: 8146 From: Boston, MA. USA (1774.21 miles northeast of Dallas) Registered: Jun 99 posted 08-13-2008 11:46 PM                        Don--how big is your screen? In my screening room setup, I use 500w lamps in Cinemeccanica lamphouses with Century 35mm projectors (with 100-degree shutters, even) and find that the image is plenty bright for an 8' wide scope image, as well as all other formats (common height setup). Throw is something like 25'. Either your screen is much bigger than mine or the ORC lamphouses really suck.  |  IP: Logged
