Q 01. Where do I buy Pau Lope hardwood? Pau Lope is grown in Brazil, it was just hardwood that I had on hand. Any clear straight grain hardwood will work.
Q 02. Are their light leaks with your back design? The whole interior of the camera is painted a flat black. The Back frame fits into a 3/8" x 3/8" rabbet in the camera body.
Q 03. How does the Graphic Back stay flat? The back frame is made up of 3/8" high by approximately 2" wide hardwood. The width is determined by the required film opening. The glued butt joints are reinforced with 1/8" x 1" long x width of wood dimension splines. The spline grain must run at right angles from the joint seam. Clamped in a flat position for drying.

Q 05. How do I adjust the back's film plane to match the Ground Glass plane? Trial and error is the best way.
