Spool anti Drift

Although the Spool has no side load it was decided to lock it using the Sprocket side Bearing Mount Threaded holes, the Spool was marked through the bearing mount holes and drilled 5/16" NF tapping size, the Bearing was located over the spool holes and a tap was run down the mount holes into the Spool.5/16" NF set screws with spring washers were then screwed into the bearing mount holes securing the Spool.
