Plaster Cloth in Tunnel Areas
Cut several 4" x 8" sheets of Plaster Cloth. Plaster Cloth is only applied along
Tunnel Portal placement positions at this time.
1. Hold Plaster Cloth sheet by the corners, dip in water
(Fig. 12)
and place on
Riser bumpy side up. It should overlap sides of Riser 1/2" - 1". Position sheet
approximately 6" outside Tunnel Portal Placement 1
(Fig. 11
and
13)
. Rub plaster
bumps with wet fingers to fill holes in cloth and smooth out any wrinkles
(Fig. 14)
.
Plaster Cloth must be flat and smooth under Track-Bed (see next section).
2. Apply additional sheets of wet Plaster Cloth, butting together at the seam. Do
not overlap sheets. Continue laying sheets clockwise approximately 6" past
Tunnel Portal Placement 3.
3. Apply Plaster Cloth in the same manner beginning 6" outside Tunnel Portal
Placement 2, working clockwise 6" past Tunnel Portal Placement 4
(Fig. 11)
.
4. Wrap Plaster Cloth snugly around bottom of Overpass
(Fig. 15)
.
5. Under the Overpass, lay a dry strip of Plaster Cloth on lower Riser and mist
with water from a spray bottle
(Fig 15)
. Smooth cloth in place.
Test Fit Track and Lay Track-Bed in Tunnel Areas
1. Place entire track on layout and pin with Foam Nails.
2. Trace the track that sets on Plaster Cloth with Foam Pencil. Be very accurate
when marking track placement in tunnel areas.
3. Remove track in several large sections and set aside.
4. Working clockwise, measure and cut Track-Bed to reach between Tunnel
Portal Placements 1 and 3, and 2 and 4
(Fig. 11)
. Extend Track-Bed 4"
beyond start of Tunnel Portal Placements
(Fig. 16)
.
5. Spread an even layer of Foam Tack Glue on traced track-area and on bottom of
cut Track-Bed strips
(Fig. 16)
. Let glue dry until clear (max. working time, 1 hour).
6. Lay Track-Bed, keeping it centered
between track tracings
(Fig. 16)
.
TIP!
For a more secure adhesion, use
120-grit sandpaper to sand top and
bottom of Track-Bed before adhering it
to the layout and installing track.
