Yes I know there are a lot of threads with info on adjusting the Kalart rangefinder on a Speed Graphic. My problem, I think, is a little different. I've searched for many hours and looked at all the walkthroughs and seen the old manual many times. The adjustment procedure seems pretty simple and I was going through it ok, perhaps just a bit tedious for some. I was just seeing how the adjustments went with a 135mm Xenar on an Anniversary SG before I got my Aero Ektar on it.
My initial problem was that I could not get the rangefinder images to coincide at infinity. The moveable image was too low. Turning the eccentric screw back/left could not get it high enough at infinity. They wouldn't match up. I had read that the arm that is located UNDER the prism/mirror board might be out of alignment. So I removed the one small screw in the middle to take the main plate off and see the Kalart's internal mechanisms with the cams and a spring and whatnot.
While lifting the board up the spring part popped off so I am not 100% positive I have it back together right but it really only seems to go one way. Does anyone have a photo of the internal mechanisms? Not the mirror part but under that. I cannot find one anywhere online. The closest is this:
But that only shows the arm attached through the camera side/body to the big silver follower arm that follows the eccentric screw. I also am not 100% sure I have the little metal spring/wire set up right on that main internal arm. It's the one in that link in the 3rd image. How I have mine on there it just doesn't seem to do much of anything.
I've set the whole thing back up a many times now with how I think it is supposed to fit together. But with the rails racked all the way back (so the rangefinder should be at/near infinity) the images only coincide at about 10ft. Moving the rails out obviously lowers the image which doesn't help the infinity problem. Also sometimes the moveable image will not start to move down (while turning the focusing knobs and extending the rail) until a few turns of the focusing knob. It just sits steady and then begins to move after a second or so.
Also wondering how far is the max adjustment supposed to go? By that I mean how far out (so close focus) on the rail? I've read it can only focus accurately maybe down to 6ft. The follower arm on the eccentric screw stays in positing for quite a while after that point with the rails racked pretty far out but the internal mechanism doesn't look like it can go any further on its adjustment with the way I have it set up.
A bit wordy but I can't really find anything close to what I need elsewhere online. All the old threads do is mention the standard procedure and point to the old manual which doesn't help with the internal mechanisms at all. I guess I just need a picture of the internal cams/springs to make sure mine is set up right and then to know why the infinity moveable image is so low.
My rangefinder also seems a bit different. There is no 'loosen' screw to unlock the long-scale rear adjustments. I can just push both the long-rear and short-front adjustment sliders with a small screwdriver. Don't think that matters but haven't seen any photos of one exactly like mine.
