[Amps] Workshop Danger

[N1BUG]

I still make most of my holes that way. The (rare) exception would 
be when I happen to have a hole saw the correct size - or slightly 
under size and finish with the half round file. If I had to take 
everything to a machine shop or buy the "correct" tool for every 
job, I would have no homebrew gear.
