any repair tips for a leaf shutter?
I have a couple of Retina Reflex IIIs with slow shutter blades (true
of almos all of them). Since most lenses with leaf shutters are MF lenses, is there some long-lasting trick to make them come back to life, such as using very fine graphite powder, or do I have to bite the bullet and pay for a full shutter service from those competent to service Compur shutters? Perhaps there are some current or ex-camera repair people here who have worked on Compur leaf shutters who can answer my question. |

Just rescued a Compur leaf shutter for a Graflex. Used the old trick of
removing both front and rear lens cells, then repeated flooding with Ronsonol lighter fluid. Cleaned out all the gook (and what looked like graphite) - the shutter now works like a charm.

Perhaps there are some current or ex-camera repair people here who have worked on Compur leaf shutters who can answer my question. Best way to clean any leaf shutter is to take it apart right down to the shutter blades and clean the parts. The other method is to remove the glass and flush the shutter with Ronsonol lighter fluid or naphtha, results may vary with this method *and* the shutter must be dried completely. The last thing you want to put in a shutter is "graphite" as it is to course and may cause problems; especially if it mixes with the light fluid making a thin paste. |

The way to restore MF leaf shutters is to remove the front and rear lens cells and flush the shutter assembly with lighter fluid. The better fluids, like Ronsonol, seem to work best. Dry the assembly completely before you reassemble the lens cells. NEVER use graphite on lenses: It is too coarse for the precise movement of leaf shutters. I have yet to find a manufacturer who uses lube on their shutters. |

If the blades are sticky, I remove the lens cells and carefully clean them with "lens cleaning fluid" I bought in generic form from the camera store using a q-tip. You might have to flood the blades with fuild, them wipe off the excess after working the shutter. Never had one that didn't come around doing this. Do -not- use any lube on the shutter blades, they are suposed to be dry. I don't like the flooding the whole shutter deal as it washes out -all- the lubrication in the shutter. -- Stacey |
