	For anyone who hasn't got access to a milling machine, use a
jewellers saw or small hacksaw to saw out an oval slot between two holes
you've drilled at the intended ends of the slot. A set of fine files is handy
to ream and finish the rough cut. Tips: 1) centerpunch before you drill to
avoid slop, 2) cut and drill slightly less than you need, the filing will
widen the slot. 3) scribe an outline of the oval before you start. 4) _don't_
put any weight on the saw, as the blades are very delicate and fairly pricey.
If you're cutting aluminum, the weight of the saw will be enough to cut
fairly quickly. 5) use a _wood_ vice, and wrap your workpiece in cloth to
protect the finish.

	With practice you can layout, cut, and finish small pieces or kit
boxes in about an hour.
