It seems to me (sitting here in my armchair, yards from my shop) that
it may be easier to make a jig to pre-punch the holes. I.e. hold the
part, locate the holes, let you pre-bash a nail or equivalent through
them to get 'em started.

I could see getting fancy and making something that punches all
necessary holes with one stroke of a lever, or something as crude as
a few holes in some angle, through which you run a nail and bash
away.


If the aluminum is thin enough, you could modify a three hole paper
punch.

I'm using 14 mil thick roll flashing. I think I would still be stuck
doing only a couple at a time, vs 10 with a drill. A Roper Whitney punch
can handle 4 or 5 at once, but not 10. With the right drill & lube, I'm
hoping to get up to a dozen or more at once.
