The intermitant drive gear( Fiber gear on vertical shaft behind fly wheel) may need lubricating. On older Westars I have seen these lock solid.Remove the fly wheel an just have a look at the vertical shaft. If You know how to take out an refit the intermittent, remove it & you may get the gear moving the full rack.

Mathew, the Westrex Westar 2001, one of which I'm leaning on in my picture, is almost a carbon copy of the Century, the early Westar Projectors carried a plate which read 'made under licence from the Century projector company New York'. The framing mech and intermittent are different, but are cross compatible. If you fit a Century intermittent into a Westar you will not have full framing adjustment, you have to modify the intermittent carrier (I think that's right, but it's been a while since I've done this).Garry, the most likely cause for your problem is that the sliding area of the vertical shaft has run dry. If you look at it as described above, you'll probably find it's black and sticky, or worse, red with rust. The sliding area is the section of the shaft exposed as you move the framing knob up and down. Don't be tempted to blart it it WD40 to unstick it. It will unstick it, but the dried grease and bits of shaft, rust, dirt etc, which get into the bore of the gear will form a lovely abrasive, and in no time at all you'll start to have ghosting, which no amount of shutter adjusting will get rid of, the reason being that the key and keyway in the sliding gear are now worn away, requiring a new vertical shaft assembly. What you need to is to remove the shaft and strip it down, cleaning and re-greasing thoroughly, or have an engineer visit and do this. Point of interest. Once upon a time Westrex supplied specific lubricant for this area of the shaft, known as 'anti-fret' grease. Did Century ever do this? If so is it still available?
