The different size dumb bells are to cut different depths. The cutter remains the same. It is better to change the diameter of the dumb bell then to simply raise or lower them. When the dumb bells centers are aligned with the center of the cutter it will cut the same depth when you rock the guitar left or right like when you're in tight places. I actually have about 5 sizes that meet my needs.
The side just slides along the nylon dumb bells. I haven't tried making them roll but, I believe that little bit of resistance might be better for control. In any case it isn't a problem not rolling.
