Author Topic: Century takeup reel arm question Casey Rogers Film Handler Posts: 12 From: Boston, MA Registered: Sep 2014 posted 01-04-2015 02:59 PM                     Hello, This is probably a easy question to answer but I'm a newbie so any help is appreciated! I'm attempting to attach a Kelmar 7000 series takeup arm to a Century projector. The Century's I've worked with in the past had a rounded take-off pulley in the sound head that would connect to the rounded pulley on the lower arm. This projector appears to have a gear where I was expecting to find the rounded take-off pulley (see below). Does anyone know what kind of belt I need to get that will match the match teeth on that gear, and is this something I can pickup at Sears or a local auto parts store? Also will a belt like this be able to work with the rounded pulley on the lower arm? The projector head is a Century HH and the sound head is Century TR-3-C. Thanks in advance.

If you look on the outer bracket (same one that has the tension idler for the belt to the projector), you'll see there is a hole where the take up pulley should be attached. The take up pulley has the mating gear to that one and will in-turn drive your lower reel via a belt (preferably a V-belt but many use Roundthane.  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 01-04-2015 04:54 PM                     Yup, you are missing the pulley entirely. In the picture below it mounts in the empty hole (bottom right corner). However the picture below also shows how you can put a Simplex takeup pulley on the shaft and drive the reel counter-clockwise (for those of us who prefer that).  |  IP: Logged Chase Taylor Expert Film Handler Posts: 175 From: Troy, Alabama, USA Registered: Mar 2001 posted 01-06-2015 10:10 AM                        What size belt is typically needed?  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

Often, one has to size it based on all of the above. I had some rule of thumbs for some Simplex Sound heads to Kelmar and Ballantyne take ups but not for Century.  |  IP: Logged
