On the subject of drills...you are using the wrong type of drill....
You have two choices to make nice round holes in aluminum with a drill.
Step Drills and Brad Point Drills...I personally prefer Brad Point
Drills...However, to use a brad point drill in aluminum...I highly
recommend that you use a drill press.
As far as punches go...you need a Whitney Punch...(a big one)....they are
great. I wish I had one...but it is low on the priority list of tools to
purchase in that you can only make holes with it...and I already have a
milling machine which can do the same thing...
John Marshall has the type of punch you need...he purchased his
surplus...which is a great way to get one of these useful tools.
