Sam.............an air board is a pneumatic tool that takes the arm
work out of sanding, but they are thirsty and require a beefy
compressor. At least the one I own does.

Often called a straight line sander. They take a bunch of air, like he
said. You need a 220 volt 5 HP compressor at a minimum, or you will spend a
bunch of time waiting for air to build back up. As a general rule, the more
expensive ones use less air, as they are generally more efficient.

There is a relatively cheap one at Northern,

I do not own this, so I do not know how much air it uses.

They do take a lot of work out of sanding things like wings, and prevent
wavy-ness that would happen if you used something like a random orbital
sander.
