A few observations from years of using soft releases on Leicas: I bought several from Fred and like them as well as others I've used, and better than some. Ultimately, however, Fred's suffer from the same problem of others, from generics to Nikon and Hama brands. That is, they tend to unscrew themselves and fall out and enter the zone of lost things. I've already lost three of Fred's soft releases. How, some will ask? Well, when you have three Leicas dangling from your neck and shoulders, or a Leica or two and an SLR or two, it's hard to keep up with everything, and those things work themselves out and are gone before you know it. Some solve this problem by using a touch of the lightest grade Locktight to hold them in. That works well. But, it means you can't use that camera with a cable release. This may not be doable, but my suggestion in exploring your design Tom would be to see if there is some way - perhaps a longer screw section - that would allow the release to stay on better. Then again, that may not be possible or compatible with your need for a once-around on the lathe, or to keep the price point down. I disagree with someone who suggested a $20 price would be acceptable. If you've got four or five cameras, and have to live with losing the dang things, $20 a pop starts to make it all hurt too much. Anyhow, I'm glad you are trying. Keep us posted, and put me down for a few.
