I like Jim's plugging method. Or you could cut a 2 1/4" hole in a piece of plywood as a template and then use a 5/8" guide bushing in your router with a 1/2" dado bit which should leave to a nice neat uniformly deep 2 1/8" hole to mount the caster. The guide bushing I have protrudes a little more than a half inch below the router base so it would have to be at least a 5/8" piece of plywood for the template. Or maybe you could just use a thicker piece of plywood than the 1/8" you tried to locate the center and it might not split then.

It required that I cut the legs short by 1.2 inch to maintain hight(done). In addition it requires that I enlarge the existing .86 inch hole to 2 1/8 inch at .25 inch deep. In addition the existing .86 hole needs to be deeper by 1.5+ inch but it is oversize by about .085 inch. I have tried using my drill press and a forstner bit for the large shallow hole but could find no way to secure the leg enought to get it started. Gene; Try plugging the hole flush with the old surface....then you will be able to hand drill appropiate sized holes without bit wandering....worked for me.
