Author Topic: Bauer U3 Thomas Jonsson Expert Film Handler Posts: 216 From: Bromolla, Sweden Registered: Sep 2003 posted 06-21-2005 03:49 PM                       I happened to look in a broschure for Bauer projectors from the mid 1970´s and found out the later models of Bauer U3 had horizontal xenon lamps. This was new to me. I thought they were all vertical. Has anyone actually seen or worked with any of those? They were available with xenon-lamps up 6,5 kW, but there were no water cooling and no special forced air cooling either. How did they deal with heat? It´s an odd looking machine, but two things about it are really good; the very sturdy lens turret and the motor driven "upper" spool friction. Seems to be a nice machine for 35mm films, but I doubt I would dare run old 70mm prints in it.

Extreme parts prices and difficult availability caused them to be replaced by Simplexes. Last time I was there the Bauers were piled up in the back of the balcony.  |  IP: Logged Mike Fitzgerald Expert Film Handler Posts: 224 From: Castle Hayne, NC, USA Registered: Jun 2002 posted 06-21-2005 07:13 PM                     I now have the Bauer U-2 from both the Naro and the Uptown in Utica NY and I am still looking for more parts if anyone has any they wish to dispose of. The U-2 has always been my favorite projector. They are in storage until i get off the road and have time to spend at home.  |  IP: Logged Jonathan M.

I saw LOA there about two years ago on the Bauer.  |  IP: Logged Dieter Depypere Master Film Handler Posts: 343 From: Deutsch-Wagram, Lower Austria, Austria Registered: May 2005 posted 06-22-2005 04:26 AM                     quote: Thomas Jonsson They were available with xenon-lamps up 6,5 kW, but there were no water cooling and no special forced air cooling either. How did they deal with heat? As far as I know (read it somewhere) the U2 had some mechanical cooling system. Didn't they have it in the U3 too?  |  IP: Logged Thomas Jonsson Expert Film Handler Posts: 216 From: Bromolla, Sweden Registered: Sep 2003 posted 06-22-2005 03:23 PM                       The Bauer U2 had a big air blower (Kuhlgeblase) in the projector base and a very sophisticated forced air cooling system. Cold air was blown through the aperture plate and onto the film on both sides. I can´t varify this, but I think I read somewhere that the cooling was so efficient, that it took the light from a 4 kW lamp, with the shutter open and machine standing still, several minutes to burn the film frame! As for the U3, from pictures I can´t find a separate air blower, just some sort of fan on the main motor at the bottom of the projector head. The U3´s with 4 and 6,5 kW lamps had an additional exhaust fan on top.

Fast-change single lens mounts from a Bauer B12 have been added. Mag sound comes from a Kinoton penthouse reader because at the time of purchase Bauer had no mag readers left. Some years ago, when the suppliers ran out of plastic gate tension bands, there were many focus problems with the new batch of bands, but today it work fine. 70mm screenings (this years they ran the Russian 5-part 7 hours LIBERATION) are OK, although lateral picture steadiness is not as good as with DP70s no matter how you adjust it. The U4 is a compromise comstruction because they sold it with the option of upgrading to 70mm. Changing the gates and sprockets between formats is a pain in the back. I'd prefer a U4 any time over those dreadful DP75 machines because the film path is quite open and easy to control while running. Older U2s do have magnificent steadiness, but I would hold my breath when I had to run a 40 yrs plus old 70mm acetate print through it.  |  IP: Logged
