I have a calumet CC400 monorail view camera (the model that was a continuation of the Kodak 4x5 master view.) The rising front doesn't remain in place when you release the knob.

I know that on the speed graphics there were a couple of screws that could tighten a plate against the focusing shaft ("axle") on the bed.

I don't see anything that looks like that to tighten the rising front on the Calumet. (There may be something similar, but I'm not seeing it.)

I do see that when you push the knob in, the round (pinion?) gear isn't fully lined up (centered) on the vertical toothed gear rack.

Is there some way of adjusting the tightness of the rising front on the Calumet so that it will stay up and not just slip back down? The camera doesn't show abuse, so I'm hoping it's just a matter of adjusting something....

Bob.
