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?
