The total width of the component was .535in. This just barely encompassed the width of the encoder and the length of the race on the CIM motor its self. The design does limit some of the usable motor shaft length however we still have about 3/4in of shaft length to work with.
The counter sunk holes were a mistake I made in the initial prototype. They did not fit exactly the way I wanted so I redid the mounting holes. The new design does not include the extra holes and has a few other features to make mounting the encoder etc a little easier.
I did use 10-32 for the tapped hole not 10-24. The face of the component exactly matches the face of the CIM motors. The idea was for us to be able to input the component anywhere a CIM motor typically is used without having to change mounting holes etc.
I plan on machining a few more mounts tomorrow and we will post some more pictures of the new design.
