Don't forget ABC Tool Repair, they are directly across from Wilders. Ann and Johnny are real good at fixing things. When I need a part, I just let them order it for me when they are ordering from vendor. Saves excessive freight charges. Oh yeah, most bearings ARE METRIC. On most routers, getting the collet off armature is worst job. A quick shot with impact wrench (air or electric) will usually get it off. Bearing can be purchased from Grainger, and another company formerly know as Dixie Bearings off New Bern Ave.
