I will add my 2 cents. Whenever possible use a tapping guide. #8 and smaller can be quite tricky freehand in aluminum.
Make sure you use a lube that works on Aluminum. Brownells smartly carries a lube that is good for everything. It's called Universal Do-Drill. Do not use a lube not designed for aluminum. We use Tap Magic Aluminum and Cool II at the day job
The proper Tap type and quality is also important.
Spiral point taps work very well in aluminum. The chip will string out and not bind in the hole. Forming taps work well too.
UPS has an upgrade service for like 40 bucks you gain better control of what happens with your deliveries.Where, when etc. They also notify you in advance when a delivery is coming your way.
