There has been a useful thread in the card structure modelling forum.

I have been working on the free Metcalf signal cabin from RM Jan 2012 as a gate box for Jenswell.

I have added the roof and name boards to my signal box.

 

 

As I mentioned before, I was not too impressed with Metcalf's tile print.

That's the one area that really seems to let down Metcalf kits in my view.

Fortunately it's easily fixed...

 

I glued SuperQuick grey slate paper over the Metcalf roof then scribed it with a butter knife to give some relief.

For N-guage/2mm I just emboss the rows, for 4mm I scribe between the slates too.

It's a fairly tedious process but the results are well worth while.

 

The roof is braced internally with 2mm card so it can be removed for access to the interior when required.

I also added guttering from black craft paper. It will need downpipes too.

 

 

The name boards were created on my Paint program (Fireworks) then printed to size on cartridge paper.

I cut them out and coloured the edges with a grey marker pen before sticking them in place.
