    Cirkut "Look Down Wedge".

    Okay, I've heard of these things for years. One just sold on eBay Item number: 7606730969. I'll admit to being rather dense, but I don't understand how the thing works. If it fits between the camera and the gearhead, doesn't the pinion gear mesh at an angle to the gearhead teeth? I suspect there is something obvious I'm not understanding.

    Len, I'm with you, but it seems to have a gear train transfer so that the camera gear drives another train which drives against the tripod head. I'll be thrilled when I get the camera running good enough to drive itself let alone another whole gear train besides.

    The ability to tilt the Cirkut, thus keep the horizon level, was patented by Eugene Goldbeck. With the patent number one can download the original patent. ( I'd give you the number, but I must find it !) The mechanism is fairly simple, essentially like the drive shaft on an automobile. Say a square shaft sliding in a square tube, one end of each with a universal joint. Add a pair of boards with a hinge along one edge and a couple of thingies to hold/attach the magic shaft and walla, or voila'. Oh yes, some brackets and thumbscrews to hold the angle you want between those boards.

    All the wedge brackets I've seen simply extend the pinion gear so that it drives on an angle. Gear mesh/contact is very small but they seem to work ok. There's no extra gears involved, just extension shafts for the pinion gear. Jim Lipari made quite a few sets of them and seem to be the most common around.

    If you ever shoot a large group you'll find some elevation of the camera position makes a big difference to the number of heads you can see. Eventually as you elevate the camera you will run out of fall on the lens, this is where the wedge comes in handy. Goldbeck was shooting some of his military groups (20,000 +) on platforms 200 feet high, that's where a wedge is needed.

    Photoeye had some hardback catalogues for a travelling exhibition of Goldbecks work which went through Europe 6 or 7 years ago. It's actually a 136 page book with a great range of his work in it and photos of his setups. They were discounted to about $12 each so I got a few. They may still have them. Great source of info.

    I saw some people using them out west to do landscapes with a #10 camera. They said the angle of the gear didn't have much of an effect on running the camera. Being in the midwest, nothing gets too far up or down to need a wedge. I often end up using the longer lenses too. So Jim- Have you been shooting , and what size camera do you have? What kind of problems are you having?

    Thanks for the interest, it means a lot. I sold the #8 that I made my one picture with and bought a #10. I haven't had time to get beyond first look. BUT it appears to be a low mileage 10 with a good strong spring so I'm encouraged that it won't be difficult to get it up and running strong. I plan to take the motor out and strip all the old lubricants and re-lube before I try shooting. One little item that would help is I don't know how to figure out all the necessary defaults for the kia ora gear program. I simply plugged in my numbers since the defaults it came up with were for a #8 and that's what I had. So I've got a complete #6 and #10 at this point. I just got silly and bought some 5" aerochrome film. The lure of a big X-parency or 2. Jim

    Did your 10 have a lense already? If you don't have to reset lense and gear distances, your better off. I've had some really good luck and some bad luck with it as well. Even after measuring really carefully I always test the settings by setting up a marker with writing on it, setting up the camera and shooting the marker at about five places around the center to see which point has the leaast amount of slur. I could go on about that a bit. It's a pain. Most of my cameras were "Bargains" and in need of it. Do you have a #6 cirkut outfit or #6 cirkut?

    No lens with the camera but I have a modest collection to chose from. The camera has marks for 10 1/2", 14" and 18". I have 10 1/2" and 14" Dagor's and the 18" APO Skopar I used with the #8. I'd also like to use a 24" APO Skopar. The #6 is the outfit. It has a useable 5X7 back for focus and still photo use. Thanks again. Jim

    No. The Aerochrome went OOD on 01 01 05. I bought it cheap on Ebay. The seller has a second roll.

    I bid $32. Jim
