convert to graflok from sping back

[tim o'brien]

One problem if you are thinking of using Polaroid backs...the pack film back has a lip that goes below (or in front of or whatever) of the edge where the film holder goes. So if you mount a standard graflex back against a wooden back, the polaroid holder is not going to be able to fit flush against the back.

Pretty impossible to explain, but look at a Polaroid back and then think about the nub where you pull on the film...it's not going to fit...unless you route away part of the wood so that it has a little slot to slide in.

My wooden adapter is not flat across... it is beveled from the edge of the 4x5 to the edge of the adapter.

The reducing back I had for my BJ had a raised area w/ the ground glass/spring back that was screwed into the frame for the reducing back. I unscrewed this and took off the spring back, and then drilled holes to match the holes on a graflok back from a beater speed graphic, and screwed the graflok back in place. Aside from drilling the holes it took maybe 10 min.

Hi - A bit off topic and a bit late, but maybe you can help me. I too have a B&J 5x7 w/ the 4x5 spring back. One of the springs is broken. The other spring is sprung. Do you know where to find replacements? Would be very helpful. Thanks. - stevef123@sbcglobal.net
