Hello everyone. I have a CZJ lens in a Compound #3 shutter which I've dismounted (... clip clop clip clop) from the 4x4 wooden board I had it on, and mounted to a Canham lens board (aluminum). The issue I'm facing concerns the aperture needle on the shutter. The aperture needle on the Compound is really just an extension of a circular ring on the back of the shutter itself. On the wooden board, this plate had enough play in it to allow movement of the needle for aperture adjustment. On the Canham board, the plate is pressed solidly against the board and is effectively immovable.
I imagine someone has created a sort of spacer to resolve this problem, or does anyone have another bright idea? This lens is now constant in both focal length *and* aperture, until I find a solution! :-)
