Hi, you can make a gauge to compare your ground glass and film holder distance out of a ruler and a toothpick held on with a rubber band. Then, take the back off the camera and with the ruler across the back, push the toothpick until it touches the ground glass surface. Then insert a film holder with the darkslide out (and a piece of film in it) into the back and see if the distance is the same.

Mike, I'd suggest you try and meet up with another Shen Hao user and try and compare notes. Something is not right, as Keith says DOF at f32/f45 should bring everything into focus anyway regardless of slight register problems, if there is any.

One other issue is that I have seen is GG that is not polished / ground uniformly. I have a few cheap GG pieces that have radial bowing or even an overall warp, or they don't sit flat in the GG holder. Indeed, it'd have to be really bad to explain what you are seeing but, it is possible that the GG itself isn't flat. Why don't you check two things: (1) that the GG isn't bowed and (2) is sitting properly in the holder. You might well need to swap out the back and GG, if it wasn't manufactured carefully.
Ian's right, put another SH back on there from a colleague and see what you see. Maybe you got the unlucky back or a bum piece of glass.
Good luck, let us know how it plays out.

Do both lenses give the same result? Are you using the loupe on the the ground glass. Focus on something with depth of field, is something sharp? Look at the negatives, if the fuzziness uniform are are just the horizontal or vertical lines fuzzy suggesting movement. Rent or borrow another camera, are the pictures still fuzzy. Are you loading the film correctly? Let know how it comes out. K
