Accurate but slow.

I've clamped a row of small pins upright in the milling vise with a
block of wood or hardboard on the moveable jaw side that compresses to
grab -all- the pins. They can be pre-aligned against the inside corner
of a square and held in place with tape.

If their lengths vary and you want the tops to line up, clamp them in
a small insert vise upside-down, with thin parallels under the vise so
the pins extend beyond the jaws. The pins can be stuck upright onto
double-sided tape to make handling them easier.
