Don't forget to use compressed air to clean up your work and bits. Watch yer eyes when you do that! Usually, I place a cloth over the hole to trap the debris while I shoot the hole with air.

For mobile pieces, I love to use my drill press adapter that permits me perfectly vertical taps. The drill press keeps the tap verical while I hand tap the piece. Sweet. Got mine at MSC.
