Long story cut short.

After seeking advice about through the bowlers who attend on a Thursday, I was filled with apprehension about the prospects of success in skimming down a pair of bowling bowls by up to 6 mm.  Firstly there seems to be a lot of mystique  about their construction.  And I have never turned lignum before.  Anyway I have bitten the bullet.
