Tuyere Iron: a Slotted Grate Cast in Grey Iron

The tuyere is the opening in the bottom of the forge fire through which the blast is blown. Bacon (1919): its openings must let the blast through easily while keeping cinders from dropping into the blast pipe, and there should be a way to open the pipe below and clear out the cinders that still get through. This one is a slotted grate over a socket for the blast pipe, cast in grey iron. The design and sizes are ours. The picture: our drawing.

Make the pattern

From pine, make a pattern of a square plate about 15 cm across and 2 cm thick with four or five narrow slots, and a short round socket under its centre to take the blast pipe. Taper every side slightly so it draws from the sand.
