    All. Here is the best tip for bearing removal I have ever been given.
     First soak the bearing in penetrating oil and remove all the set
    screws. Second use a pipe that will slide over the shaft and rest
    against the bearing. Place the end of the shaft on a large wooden
    block.  Use another large wooden block on the pipe end of the shaft. 
    Wack the block against the pipe with a large hammer.  I use a 5 pound
    sledge.  Sharp blows will lossen the bearing quickly.  After bearing
    removal go over the shaft with fine metal sand paper to remove most
    rust and burs.  Lubricate the shaft with bearing grease and install
    the new bearing. I have never seen a lapidary shaft that did not use
    a stock bearing.  Check with a bearing supplier and I would bet they
    have a replacement that will fit your shaft.
