Occasionally I etch my own circuit board and then drill it to accommodate through hole components. Components with rigidly positioned pins demand fairly accurate hole placement. This is not so easy when free hand drilling, especially when the drill bit is 0.03 inches in diameter.
My solution is to build a series of templates to guide my drilling. They are made from pre-drilled circuit board material so I just cut them out, solder in two alignment pins, and mark the holes.
