Good vid again there John
Brought back a good few memories when I work ( time served ) at Stanton lots of moulding went on there ( they had a training school for the apprentice moulders )
most of the work was rammed up with a sand slinger , but a lot was old school including vertical pipe casting to 36 inch, I had two uncles that were in the moulding trade one a brass Moulder the other worked on the big stuff ( slag ladles ) they were done without patterns the mould being built up with bricks sand clay horse dung and struck off with a shaped strickle , these took a long time to build up.
as was the norm the moulding building had very few windows and were quite dark to enable the guys to see the colour of the metal
when I left I had just installed 3 750kw induction furnaces for ductile iron from which amongst other things was cast nut and bolts ( shell moulding ) that could be screwed together without machining
the about furnaces were the babies up Dale and 18 foot they had 1.5 mega watt jobs
rest assured they to had the same problems with the patterns as you had
