I have a 16 - 32 drum sander and it works good....i do a final sanding with my orbital sander. For those that don't have a wide belt or drum sander, just wonder what your process is. I seem to never be able to join multiple boards well enough without a little raise in some of the edges that causes major sanding. I finally got the 16-32 to minimize all of the sanding and now thinking about a larger dual drum closed sander so I don't have to make adjustments that are needed for something larger than 16 inches. I would love to go straight to a wide belt but cannot afford it.
