a band saw the blade is a contiguous loop, in a scroll saw the blade is just 5 inches long (6?). You can thus put the blade through a hole in the work and cut inside parts (if you can weld blades you could do this with a bandsaw). Bandsaws have a blade guard which makes it a bit harder to see where you are cutting. For find work like the above a scroll saw is better than a small blade in the bandsaw. However the bandsaw can do much heavier work (resaw) and so if often a good enough compromise for people who don’t do much fine work.
