Unfortunately I have been very busy with work over the past month, but I have managed to progress the 31 a bit further.
I have managed to finish both bogies (there is still the sand pipes to add) and then moved onto the body.
Here's the number one end right hand side (if you were sat in the cab), this has the brake pipe work, there isn't any on the other side as it appears to go across the inside of the bogie to reach the other side. You might notice that the motor end looks higher than the front end, sadly it is here. I checked everything against the drawing and everything is exactly as it should be, but it isn't level, so I have had to cut about 1.2 mm from the compensation beams to level it up.
It looks a lot better here
Here I'm fitting the brakes and the brake pull levers, this needs to be done in a couple of steps, trying to do it all at once didn't want to work.
First you need to drill out the levers then solder the brass castings and the 2 levers together. You can then glue one of the brakes in position, once that is done the other brake can be positioned and the levers put on wire through the brakes and then the remaining parts can be glues together.
Personally I wouldn't try and solder these together as it has to be done with the wheels in place, they will be covered in flux if you do and need a great deal of cleaning up.
