i plan on changing out the bearings on my x2 mill and need to know how to remove the bearings and spindle from the head. i tried tapping on it but it didnt budge. probably get the bearings from this place http://www.worldbearing.com/sizes.asp?seriesID=6000 the ones that are in there feel a little grindy and make funny noises. i might also upgrade the bearings on the motor, too.
