I'd guess that you'll want a platen heavy enough to not distort from the generated heat, and I think I'd want to face it with a full-size graphite pad. I understand that a bit of tape around the center of the rollers can provide all the crown needed to ensure tracking.
I think I'd want a full-length fence similar to a jointer fence, so that I could shift the position of the fence when the belt at the current position wears, and so that I could sand beveled edges accurately.
Seems like dust collection and a really solid base would be good ideas. :-)
I've never built one and my only belt sander is a 1"x42" - if you build one, please post photos to news:alt.binaries.pictures.woodworking.
