A-FURNACE PART 20
I had been putting off the hot blast main on the stove assembly for a few weeks. It is a bit more difficult than it appears. The hot blast valves are a simple 3/4" dowel with some turning done to create the center seal section. Much more detail will be added. This valve is cut to fit around another 3/4" dowel that horizontally connects to each of the stoves. Thats the easy part - the 3/4" dowels connecting the valves to the main are more difficult. They come off the hot blast valve and hit the main at a 30 degree angle. Well that might be sort of simple if the main didn't take a 10 degree turn after the first valve. The second valve attached at a steeper, 40 degree angle, and the third valve reverted to a 60 degree attachment, but of a different length. The whole thing was a big mess but with some filling and sanding I'm hoping the pipes look like they flow well.
