I've had a Korona 4x5 (actually 5x7, but with a 4x5 back) with a Schneider 210mm (pre-WWII) for several years but have not used it as much as I'd like. That's about to change. I'm planning to buy 75mm and 135mm lenses in the next couple of months. The lens board size for this camera is 3"x3" and I'll need to make a couple of boards for the new lenses. I have lots of woodworking tools in my shop (table saw, drill press, jointer, planer, etc.) so fabricating them from wood would be a piece of cake. However, I'm unsure as to what kind of wood to use - cherry? I have plenty of that laying around. Or would it be better to make them out of plastic?
