I did the bearing race in mine with a rivet gun and bearing race installer tool from harbor freight. Not sure what your tool looks like but if it's just a race it should be fairly simple to do. Advantage of a rivet gun or air hammer is hundredS of small taps per minute instead of big whacks...
Call Dale Canady. I had him do the inside of my old house in Covington, and he is in my current house in Conyers. Does quality work at reasonable rates.
