The parts shown represent a substantial investment in castings and include many hundreds of hours of high quality work - it appears to need only a pair of eccentric rods making for it to run on air.\u003c\/p\u003e\u003cp\u003e    A steel boiler would be the sensible choice for a narrow gauge engine of this size, with overwhelming advantages over copper in terms of adhesive weight, strength and cost; the platework for cab and tanks could be laser cut reducing build time, after which it's largely a job of assembly, fittings, pipework and paintwork. Not a five minute job - but much of the heavy work is now done, that remaining could be done with modest facilities (although requiring a strong bench!)\u003c\/p\u003e\u003cp\u003e    We sold a good example back in April last year, \u003ca href=\"\/products\/7-14-inch-gauge-0-4-2t-tom-rolt-stock-code-11842\/\" target=\"_blank\"\u003ethere are pictures and video in the archive\u003c\/a\u003e if you want to get an idea of what the engine will look like when finished.\u003c\/p\u003e","brand":"Station Road Steam","offers":[{"title":"Default Title","offer_id":54020030366037,"sku":"12882","price":3950.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1023\/0094\/2677\/files\/12882-1.webp?v=1779909898","url":"https:\/\/stationroadsteam.com\/products\/7-14-inch-narrow-gauge-part-built-0-4-2t-tom-rolt-stock-code-12882","provider":"Station Road Steam","version":"1.0","type":"link"}
