This is a nearly finished layout for the bed of the camera. I’ll use a long threaded rod to do critical focusing from the rear, while the front will simply pull out like a drawer. The square in the center is the steel plate which will be bolted opposite and attached to the tripod base. The front standard rail has an extra piece in the front center for a possible second tripod mount. Right now, I’ve cut the vertical (6) oak boards to reinforce the main bed, and the front standard bamboo rails hace been cut and assembled. I’ll post photos is a few days.
