I constructed the gas burner as per the drawing derived from the CAD set I found on the internet. The first items I made were the body, air regulator and gas jet holder.   These were relatively simple turning jobs on the lathe.  The cross holes in the main body were drilled on my milling machine using a rotary table mounted vertically with a 3 jaw chuck to hold the wor...

Progress As of August 2018 most of the major parts have been completed, these include: Frames and Running Gear; Cylinders; Valves and Valve Gear; Footplate; Smokebox; Cab and Tanks; Bunker; and Gas Burner.

Update: Of course I forgot the trifling matter of painting let alone valve setting.  Doh!
