The three main components.
Progress is being made! All the major construction work is finished. It only remains to make the quaysides from which the bridge will spring, and I'll begin work on those this weekend using 1" blue insulation foam as a base. Once all is assembled, the bridge will be painted with Klear (Future in the US) polish to seal the plaster, followed by blocking-in the stonework with a sandy-ochre color using Crown-brand "eggshell" paint designed for use on plasterwork and wood. A small test patch can be seen on the right of the middle picture. All finer paintwork such as weathering effects, the tower sides, timbers and roofs will be done in acrylics. The interiors of the spans were painted before being fixed in place.
As mentioned before, all major construction was done using plaster casts made from the versatile Hirst Arts molds. The roofs are of card with the tiles cut from individual strips and the whole treated with Klear for additional strength. For ease of transport the model was built in three sections which will rise to five when the quaysides are done. This has the added benefit of allowing me to insert different central spans over time, such as a broken one showing a bridge demolition, and perhaps a Dutch-style double drawbridge to allow passage by masted vessels. The figures posing on the bridge are natives from my Daftest Africa campaign world awaiting their basework.
