This weekend has seen work continuing on the 10 year overhaul of No. 7. The boiler tubes have been ground off at the firebox end and then each tube is individually heated and then rapidly cooled in order to shock the metal into a rapid contraction so that it can be hammered out of the boiler with a slide hammer.
Meanwhile in the machine shop, a newly acquired horizontal boring attachment for the Huron mill was delivered and tried. It will now be overhauled and painted before being put straight to work on the overhaul of No. 7.
