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:

vtsteam:
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:
