I appreciate the help.  The SketchUp link works, thanks for that, also.  Now I have to get the components and put the baby together.

So, if I want the mortise 2" wide and the distance between the screws (I don't have bushings yet so I can't measure that distance but I know that is the actual measurement I need) is 4 5/16 I would substract 7 quarter inch units from that measurement and make the unrouted section 2 9/16?  Since this is not the actual distance between bushings, I know this is not the correct figure but just to confirm the method. 
For some reason I still can't get the sketchup to open.  I get an error message saying the requested URL is not found on the server.  I think I can follow your excellent pictures, though.
Thanks (and hoping I followed your method and math correctly)

I would like to make the mortising jig but I am having more trouble than I should have determining the length of the the un-routed portion in the bushing slot.  I would appreciate some advice in what is probably a ridiculously simple thing.  It is just not coming through my thick skull.  Also, the sketchup diagram appears not to be working.
Thanks.
