Hi Eric,

You'll find aluminium soft enough to mark your drilling point with the push
of a sharp scriber(easier to line up your markings) . Centre punch this
with a centre punch and hammer. That will get your first drill right where
you want it. Hammer across the drilling point (hold the centre punch at an
angle) if you missed slightly, to bring the drilling point back to your
mark and repunch.

Next, start with a small drill 2-3mm (1/16"-1/8"). Increase in
increments of 3 or 4 drill sizes between drilling until you reach your
wanted size. That way you will ensure your final hole is dead centre.

Hope this helps

Regards,

Bill Thornley
