You still need clamps for inbetween the corners, normally when I'm making a box I end up putting camps about every 6-8 inches.if you get 90 degree clamps, ($6 a piece at lowes and sears, $9 at home depot) if you get enough of them, you can clamp all 4 sides of the enclosure together, and have them drying overnight, and then the following day, all you need to do is the top and bottom pieces, and you're set.
*edit* Also, if you do use the method of doing all 4 sides at once, it can sometimes be a ***** to get square.
Remember kids, always check for square, if you don't you'll be cussin yourself later.
