Double water bellows (2025x10)

Ausstrahlung: Okt 02, 2025

I built two water bellows to use in tandem for smelting. Previously I made and tested one water bellow. It was small and was fired in a pit. For this project I made two that had a deeper stroke than the last one. I also fired it in a kiln so it would be stronger. I made a wide based tuyere for the two spouts of the bellows to fit into during use. When one bellow was lifted the other dropped so that a constant but intermittent stream of air entered the fire. The bellows worked well initially but then the handle came off one. So I attached wooden handles to both and they were easier to operate. I got about 2 hours of use and then the spout broke off one. This was probably due to a low firing temperature in the kiln, I could fix that problem the next time I do a firing by adding fewer layers of bricks in the bottom of the kiln. Also, the design could be modified to make the spout stronger.
