Tony Stroud reams one of the final holes on the crosshead guides. The smokebox overhead will remain devoid of insulation.

Phil Hard finishes off the week by finishing off the lagging! Ready for final jacket measurements on Monday.

The boiler is insulated with rigid sheets of calcium silicate which are scored (and cut where necessary) and held into place with wire.  They will be neatly covered with a sheet-metal jacket as the final layer.
