The design was an enlarged version of a boiler he had described a few  years previously, itself based on a much earlier \"LBSC\" design.  Designed for coal-firing, the boiler can also be run on a propane burner and  featured 51 x 5\/16 tubes with a central flue-tube superheater.\u003c\/p\u003e  \u003cp align=\"left\"\u003eThis is a professionally-built boiler by Cheddar Models, in  excellent condition having apparently seen little use. It is in copper, silver  soldered throughout and fitted with pressure gauge, water gauge with blowdown,  clack valve for pump, regulated steam take-off, blower and blowdown valve. The  firehole door is fitted with a top draught damper, the cast iron grate sits on a  tripod below with damper flap to the front.\u003c\/p\u003e  \u003cp align=\"left\"\u003eTubal Cain partnered his original boiler with a Stuart steam  pump, it can also be fed by injector or hand pump. There are a set of the  original Tubal Cain drawings with the boiler, three copies of  \"Model Engineer\" detailing the construction and the original 200psi  hydraulic test certificate from Cheddar.\u003c\/p\u003e  \u003cp align=\"left\"\u003eWorking pressure 100psi\u003cbr\u003e  Height 22 inches\u003cbr\u003e  Weight 21 pounds\u003c\/p\u003e  \u003cp align=\"center\"\u003e\u003c\/p\u003e","brand":"Station Road Steam","offers":[{"title":"Default Title","offer_id":54019775168853,"sku":"2413","price":495.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1023\/0094\/2677\/files\/2413-1.webp?v=1779907026","url":"https:\/\/stationroadsteam.com\/products\/cheddar-5-inch-coal-fired-test-boiler-stock-code-2413","provider":"Station Road Steam","version":"1.0","type":"link"}
