I've got a 2x3 Century Graphic with a 101mm Kodak Ektar lens in a Graphic shutter. The slow speeds stick and the high speeds all fire at what seems like the same speed. I've been using the camera for my night photos on T, but I'd really like to get the shutter working properly. Im not really too eager to spend on a pro CLA what I could buy a whole new lens for. Im wondering if there are any good resources for DIY CLA. Any good resources for this shutter in particular?
