Dave, Ian & Pete removed the piston & conrod they were using as a test for the new stretch bolts, then successfully fitted A8 piston & mated the conrod to the main crank, but not before discovering the snow that had fallen on site had pushed the tarpaulin down into the Vee & frozen, leaving a 21/2" thick six foot long iceberg which we had to smash up & remove, and then had to bale out gallons of water underneath the ice, which fortunately was contained by the tarpaulin & had not got into the power unit. Mark Burrows continued weatherproofing 29's no.2 cab. Chris Thorn & his brother Tom did a sterling job continuing to sort the spares in the coach (they had also attempted to do the same yesterday, but found the lock on the coach frozen, so they tidied up the shed & started assessing repairs needed to 29's cabs), and by the end of the day, the coach is now much tidier. I continued installing sockets and lighting in the coach and successfully tested what I have so far fitted.
