N&W S1a Project - Tender Build

It has taken some significant time for me to get started on this so I thought it might be good motivation to record the progress of this build here to help me moving in the right direction.
This is a first time build so please feel free to offer any suggestions you feel might be helpful.
The (quite significant) starting point is what is ostensibly a complete and running engine. This is on around 20psi.
This much was achieved in around 5 or so years but has been sitting for another 15 since. It was built without any plans. It was scaled up from a HO gauge model built by Tenshodo (Ginza, Japan) and a couple of 6x4 photographs of the prototype taken from O Winston Link’s Locomotive Cyclopaedia. It has been built to a scale of 1&3/16” to the foot, so around 1:10. This should please the other N&W builders here. Pity we are separated by a big sea!
There is a bunch of detail to complete on the engine as well as most of the plumbing but I thought it best to work on the tender first so I can sort out my mistakes early then come back to the engine once that is all squared away.
So here is the start of the tender build. It is also proof for later on that I at least started with a clean bench (didn't last long!).
Milling excess of the 1" box to make channel
And the basics of the frame ready to be bolted together (which is now all done).
Even though it is bolted and quite sturdy, the plan is to square all this up and clamp it tight then weld it all together - just to be sure. The rear coupler was built at the same time as the front one on the engine.
More soon.
Regards.
