O'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...

The 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.

In 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.

The beautiful scrapping yard scene features two vertical boilers lying on their sides with their steam tubes exposed in various stages of being cut up for scrap. 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.

The attention to the smallest detail is evident. The story telling is paramount in the development of each new kit. 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. SierraWest kits are unique in the level and amount of detail provided. Since all four sides are fully detailed, you have a ton of flexibility in placement and view-ability.


Here are just a few of O'Neills Features:

 - Laser Cut Jigs and Assembly Aids

 - Laser Cut Windows, Doors, and Wall Framing

 - Beautiful New Signs Meticulously Researched and Reproduced for Accuracy

 - Ribbed and Corrugated Roofing, New Laser Cut Shingles, Tarpapers

The large scrapping yard features two boilers with their steam tubes exposed. These boilers are being cut up for scrap metal. This is such a fantastic scene and one I have always wanted to create. The clutter is so realistic in its appearance that it is difficult to remember this is HO Scale and that the entire diorama is only 11 inches square. As you study the following photographs notice the rich deep, warm colors. This is all created with water based paints, artist chalk, and rubbing alcohol. My techniques have been used all over the the world by many award winning modelers and I am so proud of their results.

The details on the welding and repair shop dock create a scene worthy of being located right up front. All of these details speak of a busy operation with the appearance only individual castings can provide. Pay special attention to the wonderful hand truck. This is a new type of detail I created especially for O'Neills. It is impossible to cast such an accurate appearing hand truck in metal or resin so I set out to laser cut them in a prototypically thin material. You are going to love weathering and assembling these new details. Additional laser details include the raised kerosene tank support, pallets, iron railings, and saw horse ends. These details are scored so you simply fold them along the score line and glue the ends together. They are really amazing.

Removing the covered driveway exposes the raised concrete slab (resin casting) and sump underneath. The wonderful oil drum tipping cradle is one of my new laser details. Oil drums were off loaded from trucks using the tires to cushion their landing. They were then clamped onto the cradle and tipped over the sump where the oil would drain and be pumped into the large oil tank. Can't you just smell the oil? I assure you that the oil stain is 100% totally dry in the photograph. I will teach you how to achieve such realism using a water based paint and rubbing alcohol. While we are looking at this scene notice the incredibly realistic weathering on the drums. This is so simple to achieve you won't believe it. I can't wait to share these techniques with you. A special thanks to Brian Marriott for his expertise in consulting with me to achieve this highly prototypical scene.

Here is a great view of the large oil tank with the O'Neills stenciling. To get this shot the photographer must have been standing on the front dock of the next Branchline Alley kit, the Brass and Iron Foundry. It burns the used motor oil to fuel its furnace. O'Neills is such a photogenic diorama on all four sides that it is difficult to choose the shots to show online! My famous comprehensive manual and digitally reproduced accurate templates guide you thoughtfully along the construction process. I consider myself a teacher in addition to being a manufacturer. My manual provides guidance and confidence building techniques allowing you to reproduce the results pictured here. I am so proud of the number of customers who have won major national awards with the SierraWest kits they have constructed, following the provided instructions!

The rear loading dock with the carbide and acetone supplies needed to "brew" the acetylene inside. The cement loading docks are resin castings and add so much character to O'Neills. Remember, this is the back of the diorama. O'Neills includes many laser cut components to aide in your construction. These include assembly jigs, wall framing, doors, and windows. They are designed to compliment the craftsman building techniques, not replace them. This is very important. Careful thought and design practice combined with decades of experience provide for a unique building experience. I think the burn barrel scene is great. The pallets are being broken down and burned in the old drum.

This side view of the downstairs main office and upstairs small residence (for the plant foreman) is one of my favorite views. I am never satisfied to sit back and use the same techniques and castings from kit to kit, year after year. I am always looking for better ways to weather, new castings to enhance the diorama, and better scenery materials. This adds interest and provides all of us a unique learning experience that never gets boring or stale. I am so proud that my kits are always evolving and improving!

One final view of the covered dock and scrapping yard. The rich, natural colors comprising the main building provide such a realistic backdrop for all the detailing and clutter. I especially love the coloration of the ribbed roof. Like all of the O'Neill techniques, I paid special attention to creating reproducible results with a minimum of materials. Artist chalk, water based acrylic paint, and rubbing alcohol comprise the short list of supplies I used throughout the entire diorama.
