Another thing you could do if you already have the Grip glued to the blank is to very carefully drill the butt cap out being carefull not to hit the blank. Then if you have a piece of junk blank laying aroung Wedge it into the blank AGAIN CAREFULLY Use it to chuck up and shape your grip....Once you are all done mix some cork dust with some wood glue and fill the hole.... Sand the Butt cap ... And you're done....
