shifted 23700 of the weights on theGCR regulation to from 50mm to 150mm off-centre as an experiment to see if pendulum twist can be controlled.

ADJUST: -5000ms/day to 28700 owing to the added mass of the regulation platform.

cavity probe removed and insulation spacers added. Laid down on the carpeted floor to check for zero offset. Note that by 11.45am the temperatures have settled down to the same value.

pendulum stopped for access to pendulum case, plugging holes to get rid of draught. Also removed nut on Trinity Strike weight to give two dongs of extra time, hoping to get 7 days 12 hours between winds. Also fitted temporary platform to allow regulation weights to be placed up to 150mm off-centre as a means of regulating twist.
