The next thing to show you all is probably the boiler.
Here it is, complete with cleading and brass boiler bands all made by joe:

The dome cover was a bit of an issue, as this large part was missing from the original pile of bits. Fortunatley Joe managed to find a suitable one intended for a different engine (of the same boiler diameter).
It had to be machined to allow the safety valves to vent. It is a thick iron casting, so adds some extra adhesive weight.

As you can see, the boiler is all copper (so will hopefully have a long working life), and has a nice deep firebox and large firedoor, which make it a very easy boiler to manage.
The regulator handle is machined from stainless steel, and is a little overscale (at my request).
The fittings into the boiler itself are all bronze, with commercial valves etc. so I can maintain / replace them when needed.
Another change from the original design drawings is the steam turret. The drawings call for a crosshead driven water pump, and a single injector that takes steam from a valve on the side of the dome (an awkward reach).
As my loco will run mostly in short bursts around the garden, the pump would not be that useful (would be better on a long club track), so instead I requested a pair of injectors. The steam turret carries four valves; the blower (centre), the two injector feeds (left and right), and the whistle valve (mounted horizontally at the right hand end). All withing easy reach when driving, and fitted with beautiful scale handwheels.
