John,Your kind comments are really appreciated and I am having lots of fun playing with new techniques etc etc.
I know some of you are already expert at this but for me casting has always been a dark art. Having looked at a number of fantasy based sites I saw that casting paving floors, walls etc etc was very common. So although I don't know what I am going to do with this yet I thought I would give it a go, and provide a simple SBS for anyone who wants to try the same experiments. I decided to try to cast a section of rough stone wall.
Step one involved cutting a 1cm thick sheet of insulation foam, and then cutting it into rough stone shaped blocks. I sanded off the edges to give a worn look and stuck them together with white glue to form a basic wall. I then took a sharp knife and cut this in half along the long axis and stuck both halves to a piece of firm card, Step 2. This was given a coat of acrylic sealer and a thin coat of Gesso just to protect it.

I found some quick set silicone mould making putty in my local art store, Photo 4 shows the stuff I found. This comes in two parts, and like miliput etc you simply mix the two putties together to form the quick set moulding stuff. I smothered my rough wall with this mixture. Now this stuff takes about 10 minutes to set so you need to work fast.

After 10 minutes I peeled the mould off the original and voila! a rubbery mould ready to go. Step 5. I then made two casts from this mould the first in Hydrocal (like plaster of paris) and the second in quick set resin mix.

I think the result is very acceptable in both cases. The hydrocal version is probably cheaper to make than the two part resin mix.
I intend to continue casting these sections then to create some kind of house or castle etc by simply sticking them together maybe on a light cardboard backing. Notice that with the form I have made they fit together top to bottom, end to end and you can turn each casting in any direction so that the finished wall does not appear too repetetive.
I hope this is useful to someone.

Nice little model but an "osti de cochon a peinturer" as we might say here. Give me some splinter camouflage at 1/35 any day.

Just looked that up Richard, looks a nightmare to build, let alone model !Great inn John...I'm looking forward to the deck if that's what the stairs is leading to. With your skills I'd like to see you try a Minangkabau house ...that would be interesting.
Cheers,
Richard
