Just in case you haven't ordered a pneumatic stapler for the project... I know that Keith has some links to buy it online, but I discovered that the Surebonder (that uses T50 staples) is available at your local Northern Tool - it's just not in the pneumatic tools area... it's near the hand staplers.
The Monel staples are available at Lowes, but the aren't cheap! $18/box.... good luck, the stuff I got from seadooupholstery was top notch!
