I found it easy to get it fairly close by looking straight into the
front of the adapter at arm's length with a slight tilt such that
the bottom edge of the adapter is "aligned" with the bottom of
the SLR camera.  Any out-of-parallelism between the edges is easily seen.

Not sure just how perfect is perfect-enough, but that method seems to
have worked fairly well if done really often.  It's like checking the
focus-thingie on my FED: "do it often".

I've also been able to get it reasonably close by ways that Dr.T. does
mounting (kinda).  Because it's a SLR, you can see the images
"real-time" and align them visually side by side.  Obviously not a 
technique that would work with the adapter on a rangefinder or TLR.

Uh, you got me there!  Ick.
