I think it has more to do with how much tension the machine can apply to the
blade.
Wider blades require more tension to stop them twisting. Usually the largest
listed blade (i.e. 3/8) is the max it will be able to tension correctly.
Perhaps you don't have enough tension on that 1/4" blade? Or your guides may
need adjusting. The bandsaw is the toughest machine in my shop to tune up
and havie running well :-(
