I've had poor luck trying to saw boards apart with my Dremel.  Maybe my
hands just aren't steady enough?  Particularly trying to hold edge
location tolerances tightly enough to repeatably place solder past with
the simple frame fixture I made up.  A diamond wheel is way better than
a normal abrasive wheel, but still not easy for me to use successfully.

I'm happily using my little table-top 3-axis CNC mill to cut my
TeleMetrum panels apart with a very small diameter end mill and a
hold-down fixture I made up... basically a block of wood surfaced and
with holes drilled and tapped to allow me to screw the individual boards
in a panel down so that they stay in place as I'm cutting them apart.
Tedious, but I'm able to hold all the dimensions I care about to within
a mil.

If I had a suitable shear I'd use it...
