We recently purchased a used mill (Acer) with an Erickson quick change spindle. We are not familiar with this spindle and would like to remove the lock nut to clean up inside the taper. There are what appear to have once been button head cap screws around the outside of the lock nut. Are these what hold the lock nut to the spindle or is there something else we must do to get it off?
Any help would be greatly appreciated.
