Many years ago, GE had their research lab study the question of lubricating
aluminum. Their conclusion? Iodine might help a little, but nothing really
worked well. Tap Magic, kerosene, lard, etc. will cool the blade, but they
won't provide true lubrication like you'd use between the crankshaft and the
connecting rod bearings of an engine.

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?
