Tom. The recommended size is one half to one third of tramline width. Before doing anything too drastic just keep trying for a while. When you get to minimum size, centralise the bubble by holding sextant at twelve O'clock, and wind on the pressure again. Then go back to ten O'clock and wind off the pressure again. Keep doing this. The bubble will eventually dissapear. Keep at this for a while before attempting to do anything major like refilling the chamber, which is not easy with a MkIX. DaveP
