Layout your cuts and holes. Drill the holes first being able to hold on to the long stock (within reason, you might want to cut some 4' strips first). You will probably want a DP for this, but's not necessary. You can get a reaming tools to dress the holes.

AFA as the scroll saw, forget it. Not impossible, but it's not the correct tool; not even close. A chop saw will be somewhat dicey, but it will work. Watch out for the blade picking up the stock. You should use a hold down. Still, a few of the cutoffs may fly.

A band saw is the perfect tool. A table saw could be used with the same cautions. Aluminum responds well to high speed cutting. The key is to hold it down well.
