Well, first attempt is a failure. I mixed a thickener with the rubber so I can brush it on, and the rubber I am using is incompatible with thixotropic compounds. It resulted in a very low tear strenght for the rubber so its shredding from the first casting attempt. Some reading on the site would have been helpful here. So, I need to redo the mold and do it another way as well. This will require a little more time as I need to order some special materials for a new mother shell that I am out of at the moment. Not a big financial hit, but a time hit for sure. Still, learning all the time…

Of course, the good thing is the master is fine, so redoing the mold is much easier than a total rebuild.
Huzzah! That's good to news. Starting from scratch would be terrible.
I suspect you pour in the resin, stick in a few popsicle sticks, and make watch-tower-cicles…
Wont be casting it in solid resin. WAY to expensive. Looks like a resin shell backed by foam based on my first experimental cast with foam only.
Seriously! I'm curious about how this whole thing works.
YOW! How long does it take to set/dry/be ready for tons more awesome buildings?
At this stage its still not ready. I had to make a shell as well to support the rubber. That took another 2 days.
