I recently replaced the rewind shaft on my XA after one of the “feet” of the shaft broke off while rewinding a roll. I have two questions regarding this repair: 1. The rewind knob and shaft are loose, and when the lens cover is closed, and the camera is turned upside down, the knob and shaft will “fall out” until they are stopped by the “feet” inside the film cassette chamber. I can’t remember if this was the case with the original rewind knob, or if there should be something holding the knob in the top of the camera body when upside down. 2. A small metal washer/ring was removed when I took out the broken film rewind shaft. It was bent so that the last quarter of the metal before the “break” in the ring was bent outwards. I tried my best to bend it back into a round ring, with the two ends of the metal meeting up. I then wrapped it into the groove on the top end of the rewind shaft, assuming it was meant to keep the shaft from falling into the camera if you removed the rewind knob via the screw visible when the knob is lifted up. Was the bent shape the correct shape of the ring, or was I correct to bend it back into a circle? It doesn’t stay in the groove I placed it in, so as of right now I don’t think it’s serving a purpose. Thanks for your time if you’re reading this, and look forward to your expertise!
