To tighten a metal spinner backplate that fits the shaft too loosely, use a center punch to make a few punch marks around the shaft hole. This usually pushes the metal inward enough to take up a few thousandths of an inch of clearance. Adapted from 400 Great R/C Modeling Tips by Jim Newman, Volume II, an Air Age Media publication.
