shutter sound on later LTMs - continued

[michael_hassoun3]

Hi all

 

as some of you may remember I have two later ltms: one IIIc with a noisy

shutter and a cla'd IIIf which sounds like a whisper.

 

So far I figured out a first part of the problem and it seems that a wrong

former adjustment has left the camera with WAAAAYYYY too much curtain tension.

So, I put the tension to a minimum just for the sake of hearing the difference.

 

well, the second curtain is now quiet. The first one is, on the contrary still

giving me a very healthy "TSSHHHAK" even if it is hardly tensed.

 

I think the problem comes from a lack of brake action. As far as I understand

this, the brake action is set by the eccentric on the brake arm at the bottom

of the camera. This seems to be set to its minimum or close to it.

apparently, there's no way to tune the actual brake level of opposition

(spring or friction torque) to the 1st curtain trip...

This eccentric is slotted in a way that it cannot be set by a screwdriver.

 

Question: does anyone knows what tool I can use to turn the eccentric palet?

 

Thanks
