As everyone has mentioned, standard wood working saws work. The primary
thing to worry about with aluminum (other than the mess) is drilling
...marine aluminum can work harden pretty quickly if you get it wrong, then
it becomes very difficult to drill. Use the lube, use a moderate speed, and
don't push it through the aluminum too slowly ...get the bit to bite. As
long as the aluminum is cutting, you're fine. If it stalls ...don't let the
bit sit and spin, but stop, lube, make sure the bit is sharp and try again
but make sure you do what you need to to get the bit to cut metal, not just
spin around on it.
Agreement here. A final tip is to use a nail punch to center the drill
hole properly for pieces to be bolted together. The piece WILL want to
move, hence the previous advice about clamping.
