GWR Armstrong Goods Engine

The Armstrong Goods engine is the foruner of the popular Dean Goods modelled in many scales, this is a G3 version and built using a CNC mill. There are no castings available for this engine so all the parts are machined on the mill

The inside motion is fully working and can be seen as there is quite a gap bellow the boiler barrel. The steam dome is turned from 2in dia brass with the flange formed over a piece of steel bar the same dia as the boiler barrel, the chimney and the safety valve bonnet were also turned from solid.

Thanks for your kind remarks and likes. I am working on the cab, and boiler backhead and then a paint job.

The motor has an internal gearbox to give 150 rpm, this drives hex and spur gears to the rear axle, the side plates of the gearbox are CNC machined and set up with pillars. All components are sourced from e-bay total cost around £25.00
