BEST Model Sixty Crawler

Manufactured by by the C.L. Best Tractor Company
San Leandro, California
SierraWest Scale Models 3DP Kits

SierraWest Scale Models 3DP Kits
The venerable BEST Sixty crawler was manufactured between 1919 and 1925 in San Leandro California by the C.L. Best Tractor Company. BEST would eventually merge with the Holt Caterpillar Co. in 1926 to create the Caterpillar Co. as we know today. The BEST Sixty would continue being manufactured until 1932 as the Caterpillar Sixty. The Sixty is the quintessential logging tractor and is a model I have always wanted to manufacture. I never imagined a technology would emerge that allows me to create a crawler with such incredibly accurate fine detail yet so easy to assemble and weather. There's no tedious and complicated tread assembly required. Available with or without the canopy. The body includes only six incredibly detailed 3D Printed parts. Featuring a complete pair of tread assemblies for ease of construction! A separate tow hitch is included so you can adjust the height as needed. The canopy includes two 3D Printed supports, styrene, and corrugated aluminum. A link to the online instructions are included.

Farmall Regular Tractor Kit

Manufactured by McCormick-Deering at their Rock Island, Illinois plant

Over 134,600 "Regulars" were built between its introduction in 1923 and discontinuance (in favor of an updated model) in 1932. I thought this was a great year to bring this to you as it celebrates its 100th Anniversary. It was the first mass-produced row crop tractor. With its higher ground clearance and standardized features, she was an instant success and helped further the mechanization of America at a crucial time in our history. I am so blown away with this model, what a beast! I believe its design bridges the earlier steam powered tractors and combustion engine tractors. Utilizing the latest generation of 3D printers, the quality of the parts are just amazing. I cannot wait to get these parts in your hands!

24 Inch "Eureka" Engine Lathe 3D Printed Kit

Manufactured by Rahn-Mayer & Carpenter of Cincinnati Ohio

Almost 40 years ago Charles H. Brommer introduced his now legendary white metal Machine Shop kits with a series of understated black and white ads in the Gazette. How could his mastery of meticulous research, creating brass patterns that are unrivaled to this day, or his amazing hand casting work be improved upon? Enter 3D Printed parts! Each 3D Printed part is an almost exact replica of those incredible brass masters. Each Machine is faithfully reproduced as Charlie intended them to be. The prototype was manufactured in the early 1900's and many can be found today in museums and private collections. An online search reveals a wealth of photographs and information that will aide in your modeling of the beautiful piece. They’re so easy to assemble and for the first time ever, available in HO Scale as well as the original O Scale. These machines are a joy to work with and are incredibly versatile. Over the coming months, I will be making the entire set available including the beautiful vertical boiler and single cylinder mill engine, a machine shop detailing set, and an overhead belt drive kit.

SierraWest Scale Models 3DP Kits
SierraWest Scale Models 3DP Kits
A classic industrial piece of heavy machinery that will be at home in any mining, construction, or logging scene. Very easy to weather and construct. Two versions are available. Pictured on top is the full size compressor with wheels and tow bar. Pictured under that is a trio of shots showing the smaller version mounted on sleds. Both versions include seperate valve details and hand crank. Notice the different front radiator grill detail between the two versions. Please note the Ford Truck pictured below is not included and is available seperately. I wanted to include the picture with both sizes so you could get an idea of the difference.

Blacksmith Shop 3D Printed Detail Set

The first in a series of carefully researched and accurate themed sets
Available in two different versions as outlined below
SierraWest Scale Models 3DP Kits
I'm not sure there is anything more iconic in our early "modern" history than the blacksmith. From agriculture to manufacturing, the county blacksmith (and by extension his equipment) was almost single-handedly responsible for the rapid expansion of civilization. I guess it is no suprise then that many a fellow modeler has been inspired to create this scene.
The SierraWest 3D Printed Blacksmith Shop Set is available in two different versions. Both are identical except for the different sized Forge and Bellows as pictured below.
SierraWest Scale Models 3DP Kits

SierraWest Scale Models 3DP Kits
Included in each 3D Printed themed set is the following:
Forge and Bellows with support Frame and Hood (choose your size), the Anvil, 18 Assorted Blacksmith Tools, 12 Assorted Blacksmith Tongs, 18 Horseshoes (these are superb!), the Pot Belly Stove, Quenching Barrel, Quenching Drum on side with Stand, 2 Swage Blocks (every responsible Blacksmith owned more than one!), 5 Gallon Bucket, Hand-Crank Wheel Grinder, Wooden Tub, Three Wagon Wheels in disrepair, Large Tin Coal Bin and Shovel, and a Leather Slag Bucket. Also included is stripwood and brass chain as required, brass wire, and styrene tubing. NOT included: The coal pictured in the forge, the stump the anvil sits upon (a twig from my backyard).
Let's talk a bit about creating the actual scene. There are thousands of pictures online to reasearch and develop an accurate plan of how to set your equiment up, easy. Fill the quenching barrel with 5 minute epoxy that has a few drops of any "oily" water based paint and add plain epoxy to the quenching drum on stand. Add a little coal to the forge. You can add lighting to create a flickering effect since the forge is hollow and the grate is an actual grate, cool! Cut a small twig to create the anvil base and remove most of the bark. Use the supplied brass wire to bend, then blacken, and add the tool and tong holders as pictured. Be sure to hang the horesehoes on the walls. As always if you have any questions please do not hesitate to contact me.
