Anyone made a stone wall?

Hi Peter, The size is about 1 to 2.5 mm equivalent to stones between 16 and 40 cm, and the width of the wall would be about 50 cm (that is approximately the size of the one around my house). I haven't actually used the pebbles for a wall, but as filling under tracks, to give the tracks a solid structure under the ballast. I used small pebbles from sifted dirt, dropped them through the track to pile up and after wetting them with a water alcohol mixture, used a 50% mixture of water and glue to bind them; your idea of placing the glue-pebble mixture in a mold sounds good, maybe directly on the scene, but the question would be, what to use as a mold to avoid the glue sticking to it.

Ron, try this link. There may be more on our link section at the top of the nScale.net page.  This is a link I use a lot.

Lego blocks work well for all kinds of casting mold forms.

A thin coat of petrolium jelly (Vasoline?) works well for a release agent and it it is easy to remove with soap and water or alcohol.

The scratchbuildersguild website has a nice article on creating a stone foundation - a technique that could be modified to suit - best of luck!

I'd just like to reiterate the thanks for Jimmi and Michael. Those two sites are pure gold.

And I'm not even the one building a stone wall!

 If you are planning on casting, I'd suggest using a silcone mold.  There's a wide variety available, depending on your needs, etc. Not much sticks to silcone, save silicone itself.

I usually use Smooth-on products -- they're high quality and available locally for me:
