Fed 1F shutter troubles...

[atelier7]

Hi, I'm having some problems with the shutter on my fed1.

The shutter seems to be hesitant in opening, and then it sometimes gets stuck. Only when I release my finger off the shutter release button does it close. This takes place at all shutter speeds apart from B.

any ideas what's wrong with it and how to fix it?

Is this when you're using the slow speeds? I think it might need a CLA, probably might be grit stuck in the gears. I could be wrong, any other members have a say on this?

it takes place at all speeds. seems to be worse at higher speeds where the shutter opens even less until 1/500 when the shutter curtain barely moves at all. At B, it opens fully.
