    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.

    A beautiful piece of model engineering, Mike. I don’t think the ‘Like’ button does this justice.

    The tender is now complete, plenty of room for batteries, electronics, and speaker.

    Next task is cab details backhead and reverser.

    OK I pressed 'Like' already ,
    but it requires a properly appreciative remark.

    That is really lovely.

    The Armstrong is complete, the engine has R/C and sound along with the batteries housed in the tender. It has been a very pleasurable experience researching, drawing, and building the engine and kept me going during the winter lockdown.
