Hi there, I have this very specific problem with my medieval set, and was wondering if you guys had any ideas;
I'm building quite a massive 1:9 scale medieval street, with cobblestones. I found a great way to create the stones using gluegun, but, I remain puzzled as to how I should make an uneven street, using material that I can drill for tiedowns. My best bet so far is to use a wooden plank and make it uneven with a sanding machine, but this way I can't make it uneven enough, plus its a lot of work.
Is there any kind of material I could use on top of the wood to make large uneven shapes, that I could still drill through?
I should add - I only drew one wall with a strip along the side and one with a strip along the bottom - but really a wild wall would need both, so it can be firmly attached along the bottom and at least one edge.
Here are 2 more pictures to try to show how the wild wall is attached along the bottom (complete with nasty cobwebs and dog hair that I can't even see until I take a closeup flash picture!) Rather than simply put it on top of the table, I decided to set it down against the edge. Again, it's kind of confusing. I screwed a couple pieces of wood to the side of the table to support the wall and the piece of glass at the same time. And you can see that I let the foamboard wall extend down a bit below the line of bricks, which sit flush with the floor. It all fits together like a puzzle and kind of interlocks. I'm not saying this is the best way or anything, it's just the solution I came up with and it got a bit weird but it does work nicely.
Has anyone tried the method shown in this video (below), which coats flexible or rigid foam with a rigid polyurethane plastic in layers? The plastic can then be sanded, which should allow it to accept paint finishes. I imagine it can also be carved into.
My thoughts would be to have a basic structure in 1.5mm or 3mm ply, with styrofoam on top carved to cobble shapes, then coat the plastic over the top of that. It avoids having to use epoxy or polyester and glass, which would destroy any details. Polyester resin will anyway dissolve styrofoam.
If I were to use the resin/glass method (having done a lot of it for boatbuilding) I would first make a sculpt of the street in clay, then a female mould, then lay up into that. The beauty of the coating method is that you eliminate 2 stages. But you might have a compressible floor - allowing a bit of wobble....Perhaps it would be possible to extract the backing and just have the shell.
There is also a product called Jesmonite which is an acrylic resin and powder compound, that can be reinforced with glass. This would function rather like the other resins, and is also used for sculpture.
I wonder if in the end it might be worth creating a flexible female mould, and then casting sections of street from that? The shape of the backing support could be varied so different-looking sections can be made to get a really uneven and varied surface. Then whatever is cast into the mould (plaster, resin, plastic) would be thin, rigid and have all the sculpted details intact. One mould then makes several pieces.
This is a very interesting process. I will need to try it myself.
Hmmm ... I wonder if everything could be thinned enough to spray on by air brush or paint gun.
