Having done some more testing on the track, I was happy to
start the plaster work over the aluminium flywire to form the hills and landscape. The basic system used here
starts with strips of Balsawood (12mm square section cut from sheets) glued just under
the edge of the profiled fascia boards. Flywire is then stapled to the Balsawood and
the baseboards along the track edges. Scrunched up newspaper then supports the
flywire and also keeps drips of plaster from landing on any hidden track. Plastering
is done using Cornice Cement, a much better product than any other plasters due
to it having greater adhesive quality and is much harder than the average plaster.
Due to its hardness, there is only one layer needed over the flywire instead of
two, saving time! When all is dry, the newspaper is removed from underneath.

The profile boards
then get their first coat of acrylic paint which will be the final colour for
presentation of the layout. The paint is brought up over the edge where it meets the plaster.
This does two things; it helps harden the edges further, reducing the chance of
chipping and if in future any grass scatter gets accidentally rubbed off the edge, it won’t
be obvious.

The back board behind the viaduct has been applied with a photographic
backscene of” Llanberis”, a welsh mountain scene printed on a premium paper
which has a waterproof plastic backing. Applied using spray contact adhesive,
it went on beautifully and am pleased with the result. The plaster work will then meet the bottom edge of the photograph.

Till next time, Merry Christmas!
