I've got no pics but may be of some help , tombstone designs can depend upon a number of factors , a hex fixture (if it will fit) is good because you have many sides to mount parts but on the other hand if you use a triangular fixture then you can gain in clearance in getting the spindle and tool holder in much tighter to the work if your setting up some funky stuff , though you will have less room for parts , theres a bit of a trade off
is this being setup for jobbing or is it being setup for one particular production job
