The two halves of the whitemetal boiler need some filling and filing, too.
On my build I described to boiler as "to be generous, a little rough around the edges.".
A great effort it's good kit for the price - I seem to remember having to do quite a bit of work as well to get the brass castings for the springs and axleboxes straight and flat to fit on the chassis.
The one other thing to check is the buffer diameter, the buffers supplied in my kit were far too small in diameter and it makes a huge difference to the character of the loco so I had to turn some new buffers of a more appropriate diameter. Very Little Gravitas Indeed*
