Well two steps forward one step back. I was going to build a jig to slot out the bridge saddle and then thought might take it a little further and make a router pantograph. Just put the pieces together and did a test cut, still have to finish up the woodwork but I just wanted to see if I am on the right track. Well the inserted picture tells the story. Other than I have a shaky hand the 2:1 scaling seems right, my 90 degree angles are a little off though. May have to do some more research on that. But since I do not need to do any fancy work to get these latest guitars done I am going to fix the dremel in place and slot the bridges.
Figured it out. The router is offset from the pivot points. So much for being pretty, nothing that a little more lumber can fix.
