Can you please post a scan or so of a cut pcb?
maybe the edge?
I used the bungard pcb shear once, (is built like any table shear) and the
cut was really bad. maybe the machine was not adjusted properly or blunt or
something.
that led me to decide that is not the way to go.
(the edges got white a few millimaters inward where the laminate layers
were separated.)

I would really like to see one of your cuts, to see if only that particular
unit was so bad.
