The belt sander I suggested seems to be a little better to work with for small stuff. I use either 120-220 grit on the belt and 80 grit on the disc to knock down hard wood. I used my sander a lot when I scratch built a plane and I can see where it would be hard trying to use the big sander for the smaller stuff especially when the belt is in the vertical. Plus it is cheaper!! Then you could probably buy both the sander and scroll saw.
