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.

I own a 32' fishing boat.
The superstructure is 3/16th aluminum. I want to saw out the port
wheelhouse
wall as I convert the boat into a family cruiser.

I intend to use a carbide tipped blade made for aluminum on a 7 1/4"
skill
saw.

I'm wondering about lubrication. I've read parrafin wax would work. How
much
do they mean? The amount you'd rub on a snow ski or an 1/4" mound of the
stuff?

Does anyone think the skill saw idea is bad?
