White dust corrosion on steel?
 

Hi,

A few hours ago I posted a question about removing rust from a 1986
Craftsman table saw.

Well, I also got a band saw and a jointer... sorry.

The body of the band saw (I'm guessing it's made of steel, but maybe
something else) is covered with a substance that has has the consistency
of rust except it's completely white. It comes of completely with the
help of a wire brush. What is this stuff?

Thanks again,

Aaron

Im trying to remember but I think they may have had some die cast
parts. My father in law had a shop full of old Craftsman power toolsf.
I got a couple of pieces but he sold his band saw and joiner.

Aluminum oxide?

Zinc oxide, maybe, but I wouldn't expect zinc on a band saw except - maybe -
on smallish, cheaply made, cast parts.

....
The most obvious would be the thing is Al instead of steel...the second
obvious question would be "is it (the body, not the corrosion product)
magnetic?"

Aluminum oxide?


I agree. The reason aluminum is a decent outdoor material is that it
quickly coats itself with a protective layer of aluminum oxide.

Easy enough to shrink the corral. Will a magnet stick to it (the table top,
not the white powder).

Galvanized?
