Family and company for last couple days for the 4th, so not much time for the furnace. But pulled the extension off this morning to have a peek. Here it is. Cardboard pattern and wrinkles were reproduced faithfully in the refractory. I trimmed out the excess flash in the center and smoothed the whole with a fire brick used as a sanding block. Very effective! I hope to make some charcoal tomorrow, and try to work out the air supply for the two tuyeres. |

Twin pipes: |

Trying out tubing hook up lengths. The nice thing about PVC pipe is that it is the same size as iron pipe, so plastic solvent glue type fittings are a good firm slip fit on metal. The I.D. also fit some flexible hose I had, and this in turn fits my small shop vacuum. So This looks like it will work. I chose plastic because a welded steel crossover wouldn't have been removable (to switch over to the oil fired burner.) Also the weight of iron pipework needs lots of external support. I made up the Y fitting by splitting two elbows and gluing the halves together (I didn't have a Tee in the junk box). But I will probably replace that with a manifold box with an external bleed shutter so i can control the blast. Anyway, this gives me an idea how things will eventually be arranged. |

Thanks John! :beer: :beer: I guess the blower is the heartbeat of the furnace. Especially when it was bellows! Pumping that for a couple hours must have been interesting! :whip: |
