The modelling part, anyway.
I added the roofs to the MMG bunker and the observation emplacement, both made from foam-card and textured with filler for effect.
After wondering exactly how I was going to model the steel doors, inspiration came in the form of one of the small plastic bases that comes with the Battlefront/ Flames of War minis. I scored a centre line with a razor saw, glued it down to the stone floor, added hinges and supports from wooden off-cuts, and used two small washers as door handles. Now the garrison commander, the Freiherr von Talus auf dem Skree, can access the MMG bunker, and more critically the wine cellars.
I also textured the trench sides and added some supports to the log wall. I've just glued down the main walls using PVA and a wad o' toothpicks to anchor them.
Once the walls have dried thoroughly, I'll fill in any gaps as well as the odd accidental gouging and holes where I pushed the toothpicks through,. The final step is to give the whole thing one more coat of watered-down filler to soften the outlines of the stone.
Then I will set it aside to dry for a few days, clean the horrendous mess that has accumulated on top of my painting desk, and then get painting- both miniatures and Anthill.
