Even though this topic is closely related to the open hearths, I'll be spending a significant amount of time building the actual gas producers so I'll keep things separate for now. I intend to have the interior details visible in at least one of the three gas producer buildings, if not all. To refresh your memories - the gas producers are in groups of six, with one grouping supplying gas to two open hearth furnaces. Thus, with my six modeled open hearth furnaces I will have three gas producer houses with six producers in each for a total of 18. Give these multiples I plan on spending some time building the parts for a single producer, making molds of them, and then casting multiples as needed. The photo shows the early work to this end - I have turned the main vessel of the producers and the ash pan from wood blanks. I have also started fabricating the lower ring gear/drive ring from some thinly sliced PVC pipes, a .030 styrene web with .060 square struts, and a the gearing made from sheet siding material. I am using plans from an online book I downloaded free from Google - The Open Hearth, Its Relation to the Steel Industry Its Design and Operation. It was published by the Wellman-Seaver-Morgan Company in 1920. The plans are easily printed in HO Scale by manipulating the scale on your print program. They have a whole chapter on Gas Producers.
