A project that I have been working on slowly (very slowly!) over the last year is to reproduce the Siege of Dendermonde game run by Ron Miles in the 1970s and documented over 8 articles in Battle Magazine in 1977 and 1978.
I am hoping to get cracking with it this year so have been making some plans on how to tackle it. The game will be on an 8' x 6' board, half of it city and half of it siege lines.
I decided that if I really am going to crack on with the Dendermonde scenery I need to have it setup so I can tinker when I feel like it.

This is the city half of the board setup on a 4' x 6' at the end of the games room. I decided in the end to go with 6' wide and not compromise the size of the city walls.
I still have space for a 6'x 4' table for games when I need it.
I spent some time yesterday cutting 11 more hex board to complete the base board and I can start to spray the city boards grey and the ditch boards brown (they will eventually be textured) to give a better feel of how the areas split up.
I spent some time drawing up plans for the glacis and laying big bits of paper to get a feel for size and shape - a couple more revisions should have the base areas of the Glacis worked out.
I have also planned where the citadel and the ditch surrounding it will go and settled on a 75mm x 95mm footprint for the basic houses. I will also be adding a set of 1/4 depth houses along the back of the board to give the illusion of more housing, etc.

I printed out some Gabions I had downloaded and resized them to 75% to get what seems to be about the right size. These will be combined with laser cut trench sides and either plaster or DAS to create siege lines.

Finally I started sorting through the Minifigs French and British Grenadiers that I picked up on Facebook before Christmas for less then £1 each. I'll be adding French Grenadiers and some extra officers to bring the units up to 24 strength. The painter has picked units with all the same facing colours, so it will be easy to mix them, and I'll probably repaint some stockings, etc to distinguish the units.
Still lots to get on with....
There are a lot of details on how I built the Bastions and Ravelins, etc and design plans and thoughts on my blog here:
