[Elecraft] Altoid Tin Holes

[J F]

Eric,

You may want to look for a hole punch. There are plier
like devices that should make nice clean holes in the
sizes you need (at least in the ends). They are
reasonably priced, or you may be able to find one at a
hamfest or flea market.

For some holes they are less aggravating than using a
drill...
