I don't recall if I finished off this thread with a report on the results. Here's a photo of how it worked out. I connected the encoder to a dsPIC33ch128mp504 which was on a PIM installed into the Microchip Explorer 16 development board. I used my ELS to run the motor and encoder pulses were nicely formed and the dsPIC software reported both position and RPM. I have a photo of that setup but it's too large for the forum.
Looking at other stepper motors (size 23) I see that many don't even have the holes this motor has for mounting a plate so Roland's idea might be better.
