I have a metal Canham 5x7. Today I noticed a problem with the front standard locking mechanism when setting up for a shot.
In normal operation, when the locking lever is not applied, you can move the standard back and forth by turning the front focusing knob. Then, by pushing up the locking lever against the pin, the front standard locks.
Today, I noticed stiffness when turning the front focusing knob. Basically, it was as if the front standard was locked (or nearly locked) even when the locking lever was hanging down (not applied).
I have played around with the locking lever a bit and tried loosening and tightening it with an alan key. To no avail though. I only seem to be able to get it so the lever is permanently tight or permanently loose.
Any idea how I can get this back to normal operation?
All the other similar locks on the camera (rear standard, front and rear swings) work fine - i.e. they only lock their relevant movement when the lever is pushed firmly into place.
