well, i don't have access to anything more than a harbor freight drillpress, so workability is a bit of an issue.
although, i trust your judgement, so copper it is. this has probably been asked a million times before, but what is a suitable lubricant when drilling/machining copper? wd-40, motor oil etc.
right now, i'm looking at mcmaster carr to order everything, but they don't have the size copper stock i'm looking for. maybe i can call some local machine shops and get some quotes...
p.s. me joining before you = seniority. bow down
