Good evening, I am brand new to this group, having arrived at this site out of desperation (kind of). So, I have a Craftsman 1/2" router, model #315.275000 and am looking for some replacement parts, specifically Key No's 33, 36, 37 on the back of the owner's manual (retaining ring, shoulder screw and 1/2 inch collet nut respectively). I looked on eBay and found no parts, none of this particular model even. Does anyone know how I can get a hold of these parts? A friend gave me the router and it didn't have these parts included and it looks in good shape. Any help is appreciated.
