Lots of work over the weekend and the combined 3″ extension and the backscene now added. I wanted 17mm thick wood but had to settle for 18mm thick, but a bit of filing and a bit of filler kept everything level. I have maintained a slight gap between the two scenic boards so that taking the layout down is still possible.

I may look to extend the width slightly further by adding a 25mm strip to the now, front of the layout. This helps in two ways, it increases the distance between the nearest track and the edge, and also aids adding a curtain to the front with pins.

A good sand down and then some paint next.
