The mold experiment

I put together the lazer cut stairs to create the stair mold yesterday, so that the expanding foam would be dry by today (if anything went wrong) I'm pleased to say that it went very well. A huge mess was made, which I expected, but the mold did work, although it required some cleaning up afterwards with a file to even out the bumpy surfaces.

The stair mold glued together (useful to note the effect of stacking MDF, which I intend to use for the walls.)

The mess of expanding foam left on the stair mold.

The mold! It turned out very well, and with a little bit of refining, will not only accommodate the tram stop but also really give a sense of a "growth" of a lichen like material extending from the existing architecture.
