I finally got my "old arn" shaper cleaned up and running but it appears that I need bearings for the arbor since it has quite a bit of vibration and noise. Before I start tearing into and hunt down bearings I want to make sure that it will be cost effective since some of the cutters I got with it need shapening. Is there someone around that sharpens 1/2" bore shaper cutters ? these are HSS. Thanks.
