I've been trying to make an adapter for my 5x7 Gundlach Korona so I can also use my lenses already mounted to 110mm metal boards so I can swap them back and forth with with my Chamonix 4x5. I had a nice little wooden adapter made from walnut, but now I'm realizing I have some baffling clearance issues. The adapter will have the Chamonix boards going "sideways," because there wasn't enough clearance at the top. The green dots on the photo below represent a width of 7mm, and the red dot represents 10mm. I bought a set of lensboard keepers (top & bottom) from a guy on ebay, but they require I drill quarter inch holes for the swiveling keepers. Just don't have that room to do it. Also have a rounded flat brass strip but again there's clearance issues as it's too long. (Might just cut it some.) Front standard opening is about 4.5 inches square. Anybody have anything? The lenses will mostly be lighter weight, but I also hope to have some "regular" wooden lensboards made for the Korona so I can use my big heavy lenses on it, such as 300mm Velostigmat and 8 in. Voigtlander Petzval. These are just too big for my cute little Chamonix. I even had a cat scan done, but still no solution. So, any ideas here?
