About a year ago I drew up the plans for the 'signal box' - a 'Saxby & Farmer type !' - based on various sources :-

and now, finally, I'm getting round to building it. As usual I start with the windows. Regular readers will know I have my own method involving adhesive paper, acrylic, card and lots of cutting out. Well, the first three components are still there but the methodology has changed... I'm not going to take up bandwidth, but the story is here:-

.rmweb.co.uk/community/index.php?/topic/108310-darkly-labs-emblaser-affordable-laser-cutter-review/page-23#entry2376233

and yes,

These were laser-cut...

All that's needed now is walls to put 'em in -

From (l) to ® - outer wall, sash slider unit, outer sash windows, middle sash frame, inner sash windows, sash slider, inner wall....

Now to assemble it...

Are attached to the middle sash frame. I then realised a little 'thicknessing was required before

adding the 'sash slider unit'

Then

The outer wall.

Turn the unit over and repeat the steps for the inner wall...

Then repeat the process for the other three walls!

And so to bed....
