I'll just add that even a big widebelt does not really take off much in a pass. There was one post about removing 1/8" material in a pass, and I have to question what kind of machine and wood? I run a 43" Timesaver with a 25 hp motor and usually
remove in the thousands per pass. With a really aggressive grit and soft wood you could take more, but I wouldn't expect to take off that kind of material in normal use.
good luck,
