Author Topic: Century MSC or Simplex Apogee what's the better pick? Michael Moore Expert Film Handler Posts: 188 From: Dover, DE / USA Registered: Jun 2006 posted 05-11-2007 07:55 PM                        I just got home from the theater and I noticed something I never noticed before I am missing one tooth on the sprocket of the intermittent. Could this what is causing ghosting issues or unstable image? I check everything you listed Mark, all is work smooth. If I get the ghosting to go away at the bottom of the image then the top is out and visa versa. I can't find the middle for some reason. I have never had a problem like this and I think the intermittent is suspect. I can't wait to get the one from you.

Interesting. I know of one Century with one tooth gone on the INT sprocket and no evidence of ghosting....and it's been this way for years.. Besides, if both were gone and in the position of the initial pulldown, you'd have snarled film in the trap. Wonder if the drive, or driven gear on that SuperSimplex is worn, have lots of gear slop, or damaged teeth on the fibre gear that is causing some of your ghosting issues..OR, we could pick on the shutter with this one as well..the fibre shutter drive gear is worn as well...being that the shutter gear is metal  |  IP: Logged Cameron Glendinning Jedi Master Film Handler Posts: 845 From: West Ryde, Sydney, NSW Australia Registered: Dec 2005 posted 05-11-2007 09:53 PM                     quote: Interesting. I know of one Century with one tooth gone on the Intermittant sprocket and no evidence of ghosting....and it's been this way for years.. The one time I had one 35mm tooth missing (on a century jj), It was picked up on the first screening after an incident the night before. Image was noticeably poor, we swapped projectors (2 projector and a long play)and replaced the sprocket immediatly. It was many years ago now, I remember the image shake, not necessarily ghosting. Perhaps its a case of which actual tooth?  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 05-11-2007 09:59 PM                     ..this missing tooth on that Century that I mentioned was the outboard tooth. I talked to the operator there (been there for years), he knows about that tooth being gone (his story was that his relief did the classic "no-no": cleaning while the machine was running that took that tooth off the sprocket) ,yet figured that it didn't hurt the pict any and just left it as is all of the years this 3plex was in operation. Also, this was a narrow tooth (foxtooth) sprocket making it easier to bust teeth off if accidently hit with a solid object.  |  IP: Logged Cameron Glendinning Jedi Master Film Handler Posts: 845 From: West Ryde, Sydney, NSW Australia Registered: Dec 2005 posted 05-11-2007 10:15 PM                     quote: Monte L Fullmer his story was that his relief did the classic "no-no": cleaning while the machine was running that took that tooth off the sprocket Exact same reason!!!!!!!!!!!!!!!!!!!!!!!  |  IP: Logged Michael Moore Expert Film Handler Posts: 188 From: Dover, DE / USA Registered: Jun 2006 posted 05-12-2007 07:28 AM                        Again this intermittent was one that I got from a box that said overhauled on it. I did not notice the missing tooth before. I never clean while running. I do have some slop in the gears not lots but there is slop. there is no gear teeth missing or damaged on the fibers. I just replaced them with ones from my second projector. If I grab the intermittent flywheel and move it in the direction to projector moves or back; there is slop before the other gears engage or start. I think this slop comes from the intermittent itself. I'm not messing with changing the intermittent sprocket on the starwheel shaft right now. I'm going to change the whole movement out with one that Mark is sending me, I should see it in a few days or so.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 05-12-2007 09:16 AM                     I need your shipping address if you are to see it....

I have prices quotes from Cinemasupply for a Simplex Apogee and a Century MSC, I also need a new rectifier but I already have that picked out and will get it from them. I have prices for a new Kenoton and sound head from Cardinal sound and Motion picture and it's not much more in price over the all in one Century MSC from Cinemasupply so they are in my mind still price competitive unlike some people said. I also have my eye on the Rebuilt Century from Hadden and got a quote. If I get a Century from Hadden, I will have money left over to get the rectifier, and new bulb, as well as some other supplies to keep us running. I also will use some of this to get RP-35 and some other stuff for setup. I have my eye on it because I am very familiar with Century, and I can get projector two up and running by saving and adding to the money we will have left over. Also I am thinking of keeping the SH-1000 penthouse for now because I do not have the equipment to do an A-chain alignment and I'm happy with it and it works great, the century should fit to it like a glove. Next on my list is a o-scope and RTA after I have both century projectors. I finally will get new sound heads and up-grade my current sound processor. We have BACP reverse scan going into a CP-50 as a pre-amp that goes into a LEXICON DC-2 as the processor.  |  IP: Logged Scott Norwood Film God Posts: 8146 From: Boston, MA. USA (1774.21 miles northeast of Dallas) Registered: Jun 99 posted 05-15-2007 07:53 AM                        If you want to put the Century on your SH-1000, you'll need to get the non-direct-drive (non-"M") version and the coupling gear. Also consider a rebuilt X-L/PR-1014, which will also work well on the SH-1000. You'll need a loop of RP-40 (aka PA-35) to cut the aperture plates for whatever you get, plus buzz track, Dolby tone/pink noise, and left-right loops for doing the sound alignment. Oscilloscopes are available cheaply on Ebay, while RTAs are more scarce. With the BACP reader, you can probably get away without the RTA for the A-chain by leaving the HF EQ set to the minimum. It might be cheaper to pay someone to come out and do the sound alignment once or twice per year than to buy all the test films and equipment.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 05-15-2007 08:17 AM                     Kinotons are reasonably close from the factory (soundhead A-chains). Though we often will tweek them in the shop to avoid having to do A-chains in the field (we do this, if time permits regardless of the projection system supplied).  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 05-15-2007 08:29 AM                        I do not share the universal dislike of the SH-1000. I find it to be reliable, solid, and easy to deal with. While wow & flutter are not its strong points, with reasonable maintenance, the roller is not a problem either.I would probably never replace the SH-1000; but if I did, only a Century would be acceptable.
