SierraWest Scale Models 3D Printed BEST Sixty Dozer Kit

SierraWest Scale Models 3D Printed BEST Sixty Dozer Kit
The venerable BEST Sixty dozer 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.

Hyster Logging Arch

SierraWest Scale Models 3DP Kits

As the 19th Century neared its end, The “Big Wheel” Logging Arch became a standard North American piece of equipment used to haul logs by oxen or horses. Prior to the 1870’s, moving logs was performed by the grueling process of dragging them from the woods with large bull teams. In 1875, Silas Overpak of Manistee, Michigan, introduce a wheeled device from which logs could be suspended, making the work of moving the large logs much easier and logging was changed forever. In the late 1920’s the Hyster Company introduced their venerable Logging Arch, and when paired with a crawler like the BEST 60, a small team could move many logs in a single day.
The SierraWest 3D Printed Hyster Logging Arch is a highly detailed group of just seven castings and is very easy to construct. Includes pre-assembled treads, the winch that attaches to the rear of the BEST 60 Tractor, and a clevis and hook for you to crank those logs up with the enclosed cable and chain. As with all SierraWest 3D Printed kits, the Hyster Logging Arch features incredible detail with superior quality prints. Minimal clean-up and ease of assembly means you can spend your modeling time with the fun stuff, weathering and assembly! Online instructions provide clear directions for weathering, assembly and rigging a log to your Hyster.

The Cletrac Crawler Tractor

Manufactured by The Cleveland Tractor Company
Cleveland, Ohio
In Stock and Ready to Ship
SierraWest Scale Models 3DP Kits

Cletrac, originally known as the Cleveland Tractor Company, was a manufacturer of crawler tractors, founded in 1916 by Rollin H. White. The company was known for its innovative and advanced crawler designs, particularly the Model W 12-20, which was considered advanced for its time. During World War II, Cletrac produced the M2 High-Speed Tractor for the military, which was widely used for moving aircraft and heavy equipment at Army Air Force bases. In 1944, the Oliver Corporation acquired the Cleveland Tractor Company and phased the Cletrac out of production. This diminutive crawler (about 2" long in O Scale, 1-1/4" long in HO) is the perfect companion to our Backwoods Tie Mill and would be at home hauling smal logs to the landing area.
The Cletrac 3D Printed kit includes a single main body with fully assembled and detailed tread assemblies, separate engine compartment hatches with a detailed engine, and a control cluster. Please note: the HO Scale version does not include the front mounted lights, they are just too small. As with all SierraWest 3D Printed kits, assembly is very straightforward allowing you to focus on painting and weathering. Instructions can be downloaded from the SierraWest website with the provided link. This was such a fun project and I am certain you will find a home for this classic little crawler on your layout, diorama, or in your collection.

Customer Modeled

The BEST 60 by Aaron
SierraWest Scale Models 3D Printed BEST Sixty Dozer Kit
"Battle Tested" models are where I showcase my customers finished kits. Here is the O Scale BEST Sixty modeled by Aaron. He states: "Finished up the first of the 2 Best 60's I ordered. Went for used but not too abused, other than the tree branch that fell across the roof on it at the camp 47 reload. The shop crew accidently left a shop rag where they were trying to fix the cylinder leak, however the 10mm socket is supposedly still missing lol. Overall, this is a fantastic build, and I can't wait to start the next one." Thanks for sharing these pics Aaron, what an awesome job. Be sure to visit the SierraWest Gallery for more great customer modeling.
