My 4x5 camera is actually assembled from multiple junk box Graphics cameras, both Speeds and Crowns. The front standard takes the 4x4" wooden lens boards which I make myself out of 2 layers of wood: and 1/8" 4x4 board with another 1/4" thick, slightly smaller board glued to the back to strengthen it and form a light trap. (BTW, I make a similar wooden design, with rounded corners, to fit the newer Speeds and Crowns with the stamped aluminum plates...)
I want to mount a Copal #3 shutter on one of these boards and my question is whether the resulting hole will weaken the board too much. Since the actual mounting hole in the stiffening board has a 1/2" wider diameter than the required lens mounting hole (to provide room to get the flange and spanner in), it means that there will not be much of it on the edges to strengthen the front board, only about 3/4".
Would this be a problem? I'd like to determine this before I buy the new lens. Thanks.
