This is a laggardly response Ken... I still have the 300mm and occasionally think I really should do something about a lens-collar-mount. I bought the lens from Peter P. in Colorado, he had had a custom built tripod mount for it, but sold that separately. Is that the one you bought?
I have considered going to a local machinist, or into my own "workshop" and making a simple L-shaped bracket that would attach to the camera, extend forward and then up to support the lens from the bottom. A 1/4-20 hole drilled in the bracket would allow me to mount it on a tripod... Does this make sense?
