    Compur Rapid shutter help?

    I just rejuvenated a Compur Rapid on a 6x9 folder of mine. It was bound up by a dry self timer train. Now I find that B and T do not work, and I cannot even get the rimset to go to either setting. Does anyone have any hints or suggestions?
    Thanks!

    Sounds like the cover may not be properly installed. Either that or maybe the timer assembly isn't installed correctly. I had the same thing happen on a Syncro Compur and found that the main timer assembly was out of place, and that the top timer plate wasn't installed correctly.

    With some of the older Compurs, you don't tension the shutter for B and T. In fact, I believe you cannot tension the shutter on B and T with some of the older Compurs.

    Otherwise, I agree with Greg. The outer dial with the speeds probably isn't seated correctly. That's where I would start. Before you replace the other parts, turn the dial from T to the top speed (shutter untensioned) and see that it spins freely -- not easily, but freely.

    What I'll sometimes do when I have trouble replacing the speed dial is to half tension and release the shutter a couple of times at around 150 or so. Then I'll change speeds and try again.
