Was picking out the spot to dump the bucket while slewing the 360, not realising I
was still crowding the bucket & pulling in the dipper arm - until the
cutting edge of the bucket hit the right hand pillar and slid upwards
about 300.

Made a new dent in the pillar (and my pride) and scraped some paint off
but broke nothing.

There is evidence on both pillars of others who have been there before me!
