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.

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 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.
