Accuracy is not important +/- 1/4" is close enough.
I saw a real crude setup at a local septic tank manufacturer. They took 12electric hand drills and duct taped them to a 2x4 board mounted over a pipe on a table. The board that held the drills was held in place by two boards at the ends running back 4 foot and hinged to the table (the drills did move on an arc but it seemed not to matter). Overhead springs held the drills up. Plug it in, pull down and hang on, it was funny to watch this guy drill pipe, but it did drill 12 holes at one time and fast.

Dear rustyk,
IMVVHO, the septic tank guy got pretty close. You do not need accuracy, so why pay for it?
I really do not think you need CNC here
unless you want real volume production.
With a small number of jigs, and a whole bunch of $80 hand drills, you could be off and running.
BTW, the way round the current surge is to start the drills up in sequence, not at the same time.
My two cents
Best wishes
Martin
