Years ago I subscribed to View Camera magazine. In one issue were the plans to building a 4x5 field camera out of wood. Does anyone know and/or have this issue. At the time I was planning on scaling up the design for 5x7 and making it out of ABS plastic sheet. I recently discovered the ABS sheets that I planned to use, have since retired and would like to try making this camera. I really don't need it since I have 5x7 Linhof Kardan Bi. but to have a more portable folding 5x7 would be nice to have.
