Firedog casting using traditional open moulds

Firebacks website: https://hodgers.com/firebacks/ This video sequence was filmed by Tony Meades in the early 1980s at the now-defunct Rye Foundry in East Sussex. Firedogs, or andirons, were cast in two stages. For each firedog two moulds were formed using separate patterns: an L-shaped piece of metal for the rear leg; and a copy of the front of an existing firedog for the front legs. 00:00 First casting process In the first sequence the founder is pouring metal into several L-shaped moulds. 04:03 Rear-leg cooling The second sequence shows the rear-leg castings, after they have been allowed to cool for a while, being dislodged from their moulds. They are still quite hot so they are plunged into water to cool them more quickly. 05:18 Frame assembly The third sequence shows a simple frame being assembled to support the rear leg castings so that the ends of the castings hang in the moulds for the front legs. They have to be positioned so that the back of the rear leg is in line with the front legs. A U-shaped metal bar is rested against the suspended rear leg to prevent it being moved out of position by the molten metal when it is being poured in. 07:31 Final casting process In the fourth sequence the founder is pouring the molten metal into the completed mould, the rear leg now integrated with the front legs. They are then left to cool. 08:51 Frame removal In the fifth sequence the frame that supported the rear legs is removed, the front legs still being red hot. 09:15 The big reveal And finally the finished firedogs are revealed.
