Washago coaling plant--step 2

It's now time to produce formwork (we're going to pour concrete sections with hydrocal plaster). In S scale, I used 3/32" balsa sheet. Styrene or bassword would work as well. Make sure you have adequate thickness for strength. Making formwork is like modeling in reverse. Most of the time and care is employed in fashioning the mold.

Above, you can see the sections labelled as to their locations on the structure. All the main pieces are 11'-2" high. Cut two pieces 21'-0" long (outside north & south sides), two pieces 21'-0" + 2 x thickness long (outside track & conveyor sides), two pieces 17'-0" long (inside track & conveyor sides) and two pieces 17'-0" - 2 x thickness (inside north & south sides). Additionally, cut a piece 8'-2" high x 8'-8" wide x 2'-0" thick; this will act as a plug in one wall section (I used two pieces of 3/16" balsa laminated together to make 2'-0" thickness in S scale).
