In this "Making-of Caterpillar 789C & 789 "OceanaGold" Mining Trucks" we will show how these two custom models will be achieved.

Tim shares his building skills through the photos with little notes guiding us in the construction process. Gradually it shows the making of two unique models by using the two donor Caterpillar 793D Mining Trucks from Diecast Masters in 1:50th scale to create his one of kind Caterpillar  789C & 789 "OceanaGold" Mining Truck set"

Enjoy reading & watching!

What preceded

In 2023 Terra Cat asked Tim to produce a set of Caterpillar 789 Mining Trucks scale models for their customer OceanaGold Corporation.  He was aked to replicate the Caterpillar 789C Mining Truck #DT231 decommissioned chassis (truck originally delivered in 2002) and the full certified rebuilt Caterpillar 789 "Next Gen" Mining Truck #DT254. This was not a simple project as a Caterpillar 789 base model does not exist (yest-)), the closest was a Diecast Masters Caterpillar 793D base model. Hence the project involved converting two Caterpillar 793Ds to 789s then constructing the old DT231 chassis and the new DT254 truck.     

The Kickoff

Tim started with the purchase of two 1:50th scale Caterpillar 793D Mining Trucks from Diecast Masters. Of these, he could only use the chassis and partial upper bodyies but this forms the solid basis for the start of his project.
