SierraWest Scale Models HO Scale O'Neills FabricationO'Neills Fabrication is a classic early Twentieth Century business brimming with finely crafted details and prototypical activity. O'Neills evokes memories of a simpler time and would be right at home in any geographic locale. The Branchline Alley community brings their empty acetylene and oxygen tanks in to exchange them for full tanks. The small repair and welding shop inspects and repairs these returning tanks. A detailed interior includes a degreasing station to clean and prepare the valves for tank re-filling. The covered driveway leads to the large used oil storage tank and has its own unique story to tell. Read on...
SierraWest Scale Models HO Scale O'Neills FabricationThe used motor oil is brought to O'Neills in 55 gallon drums from the surrounding farms and businesses. O'Neills purchases the oil for pennies a gallon then the drums are off-loaded under the covered driveway. One at a time, each drum is clamped on a tipping cradle then up-ended over the sump to drain. Next the used motor oil is pumped into the large storage tank. This oil can then be re-sold and pumped into tankers or used by the neighboring Brass and Iron Foundry to fuel their furnace.
SierraWest Scale Models HO Scale O'Neills FabricationIn the manufacturing of acetylene, three main components are needed. Carbide, acetone, and distilled water. On the rear loading dock you will find Carbide (in the wooden barrels) and the Acetone (in the blue drums). These raw materials are brought in by rail while the distilled water is obtained by distilling the local water supply. The acetylene is produced and the tanks are then filled inside the main building. Oxygen tanks are filled elsewhere and exchanged at O'Neills.

O'Neills is not a junkyard so you will find this detailed scene is filled with specific types of clutter including the scrapped boilers, scrapped acetylene tanks, boiler tubing, drums and bins of scrapped parts, and empty grease buckets. The covered loading dock is for the transfer of the empty and full acetylene and oxygen tanks. Locals bring their empties in and buy pre-filled tanks. The side wall of the repair shop is covered in welding hoses ready for sale or rental.

Instructions are provided leading you through every phase of construction including tool selection, assembly, weathering and aging, diorama composition, and scenery creation and application. It is of the utmost of importance to me that the techniques I develop and utilize are reproducible for modelers of all experience levels. When you view the pictures of O'Neills remember this.
