So, as said the original plan was a room/corridor per tile. It would have looked somewhat like this:

I've just thrown in some random pieces as scatter terrain and nothing is actually glued. The figures are 28mm from Westwind. The astute amongst you will recognise the obvious problem with this setup. Friction. If I have several tiles built like this then when I try and pick one up to move or rotate it, the surrounding tiles will be pulled up too due to the amount of shared surface area. While the walls are pretty strong, they're only half an inch thick and I could see an awful lot of damage being caused in games.

So, after a brief re-think. I switched doors for walls like so:

As you can see, no single tile will form a room but will act in conjunction with the others to make a fluid board. This actually gives more useable play area overall and allows larger rooms. It also minimises friction, strengthens the walls and gives a convenient place to hold when lifting the tile. I also realised later that with a bit more preperation, it'll make the whole thing far easier to cast and build!

I then sat down with my technical pad to think about the tiles and what to make. The result I came up with is:

The above sections will give me all the basic options with extra straights and corners, some doglegs and two u-turns. While the doglegs and u-turns can be achieved on other tiles, having tiles specific to it gives more restriction on those tiles and allows for some interesting terrain scenes. Particularly the u-turns with their row of alcoves, just asking for statues or sconces. Currently I have six blank tiles which will allow me to place large "scatter" terrain pieces such as fountains or perhaps stairs as entry points. A blank tile cant rotate, simply because it would be difficult to lift out and there is little point as figures can leave from any side anyway. I may cut it down to four blank tiles as it strikes me that six will give too much open space. There's no way to actually tell until it's all done though.

Most of the floor tiles will be built like this, although with walls added:

A mix of cracked and full tiles to give some variation for the eye.

Some will be built like this however:

Hopefully it can be seen in these pics, it's clear on the original but Blogger shrinks them a bit. There is a pattern running around the edges and some picture tiles in the middle. This will mostly be used on the blank tiles I think but may well be incorporated into some of the others for variety.

As I said earlier, with a bit of preperation this whole build can become very quick and simple. I have now cast the standard block mold many, many times and have achieved this:

Slightly jumbled as they aren't glued yet, and it can clearly be seen that one of the straights isn't complete in that picture. It now is, the grey/brown casts shown in the last post have now set and some pieces have been used to finish that wall. Those four pieces will be glued, cleaned up and then moulded. I can then cast the walls as single pieces, which will speed everything up and make them stronger. From one cast I could make up to three tiles, assuming I can get another big floor mold and perhaps a pillar mold made too :)

That will have to be enough pics for now. Next proper update will be with a mold or a finished tile build I suspect.
