Author Topic: What's this bore for (Century)? Jim Cassedy Phenomenal Film Handler Posts: 1661 From: San Francisco, CA Registered: Dec 2006 posted 05-09-2009 10:22 AM                     I don't know about "all" Centuries; but last night I compared that JJ with a couple of SA's and SAW's & even took a few measrements, and the body castings of all seem to be identical. I didn't have a model C at that location to compare it with.  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 05-09-2009 11:53 AM                        JJ is prety close to the SA and H casting; exactly the same before machining.

I've seen a lot of them that have been rebuilt sometime, with an assortment of vintages of parts used. I think Wolk did a lot of rebuilds, maybe others as well. So finding a single shutter machine with an SA water cooled trap reading "CC" on the nameplate doesn't surprise me any more.  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 05-13-2009 09:20 PM                        At one time Century must have made 10 or 15 different projectors (see list of Essenay changeover models just for Century). It would appear that the H was an attempt to reduce the castings to one or two. (and in addition, to move the lens center to the image center) The plan was not perfect. Later, the SA was more successful; the JJ casting being identical except for machining. Complicating the picture was the elimination of the H or C curved gate kit. The SA gate kit was force fit into many C's to eliminate the straight gate problems when automation came around in the 1970's. I know, I was guilty myself.

The SA has that bore, the SAW does not. I mis-read one of the model ID plates.  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 05-15-2009 12:39 PM                        Jim; some had it, some didn't. The SA and the SAW are the same machine, just with a water cell.

In this position 2 bearings were fitted with a shaft and gear on the rear, what it drove I cant remember but the repair involved the gear etc. Stan  |  IP: Logged
