A couple of bereavements since my last post on this have slowed things down somewhat but I have made a little more progress.
Getting the rear of the tender and the tank top square and straight up has been a bit of a struggle.
This has mainly been due to the fact that the rear of the tender is mainly half etched. The half etching process in what is quite thick base material, has made it curl in several planes.
A look at one of the tender sides probably helps to illustrate this better than the photos of the tender rear.
I got there in the end.
