Kodak carousel remote focus control

[hwv]

Hi,

I got a vintage kodak carousel slide projector with two lenses. Slide transportation is working., the light comes on, but I can't focus by remote control.
I don't know if there's some gear missing between the focus motor and the lenses. There is a white gear wheel which turns when uing the focus knob, but I don't know how this should move the lens back or forward.

Please can anyone explain how this should work.

Hi Heinz-Willi,
Yes, if I remember correctly you have a piece or two missing. There is a pivoting lever with a spigot on it that locates in the thread of the lens when you screw it in to the 'throat' of the projector. Movement is transmitted to the lever by a worm gear, if I remember correctly (I don't have my Carousel here). The spigot on the lever was known for wearing badly, giving a sloppy focussing action and was a standard part to replace in Carousels. Last time I replaced one (some 20 years ago!) Koday actually sent me one for nothing. I've been keeping it well lubricated ever since. Of your three pictures, the middle one shows a lens that I don't recognise with some kind of rack and pinion focussing system. My guess is that it's from some other make of projector and is probably incompatible. Perhaps someone removed the missing part so that they could use the other lens without the focussing mechanism getting in the way?

How old's the carousel?
From the model 600 forward they all used rack and pinion focusing and a lens with the rack on the bottom(center) The projector should have a knob on the top left hand corner and a gear on the left hand side of the lens opening.**left side when viewing the projector from the front.**

Hi,

thank you for your replies. The projector is a carousel S-AV2000.
The lens in the middle is a Kodak Ektapro Projection FF Zoom Lens 75-120 mm f/3.5.
The lens on the photo to the right is a Isco-Göttingen Carousel-Projar f = 180mm.

Without the missing parts, the only way I can focus is by pulling or pushig the lens by hands.

Hi,
The S-AV2000 should be as I describe. The Ektapro range was a total departure from the Carousels that began back in (I think) the late 1950s. In the University where I work, Carousels were replaced by Ektapros but this was soon regretted, as the Ektapros were found to be nowhere near as long-lived or reliable as the Carousels. You've certainly got the better option. As it's the 2000, it will also have the 250watt lamp (though you can run with a 150watt if you wish). The 180mm lens is good for shows to large audiences in halls when you need to project from a long way back, but is possibly a little long for general home use. Kodak fixed focal length projection lenses are considerably better quality than variable focal length items.
Best wishes,
Steve
