Part four by Franco Pucci

The boiler part 1

A 63mm diameter copper pipe was the material used for the boiler.
This is the mandrel I made up to be able to fit the boiler pipe to for machining.
Making the cut for the boiler stepped section to fit onto the tender end.
A little filing to clean the cut…
Then remount onto the mill to square everything up.
The smoke box with the door ring machined.
Door ring, door, and fixed hinge in place, with the material for the moving hinge ready for machining.
Machining the moving hinge.
Smoke box door assembly completed - just missing the door handle.
Et voila! A door handle.

Time to start on the boiler insides.

But first - some proofreading…
