My 8x10 cameras use 6x6 and 9x9 lensboards. I would like to use the lenses mounted on 6x6 lensboards with a camera that accepts 9x9 lensboards with a 9x9 to 6x6 reducing lensboard. In my specific case, the 9x9 lensboards fit a Century Master Studio Camera and the 6x6 lensboards fit a Kodak 2D.

If you have a reducing lensboard, I would appreciate any information and particularly photographs of how yours is made.
