Another round of formicaria I've been working on. Not all of them have the holes drilled yet. I tried using some different molds than I did previously, and although they were easier to work with I think the silicone walls were much too soft and didn't keep flat and hold shape as the perfect cast hardened and expanded. Hopefully I can sand the tops down flat enough for the glass I have to fit snugly. I suppose if worst comes to worst and I can't get it as flat as I would like, it will still work for larger genus like Camponotus (which I have a lot of). Fortunately, this problem only happened on the two smaller square formicaria.
The small square one is a 3x3 inches and the larger square is 4x4 inches. I have some pre-cut glass squares to fit those two that I bought online. I made the chambers a bit shallower than the previous ones I made and I like that look a lot better.
Speaking of glass, on the first nests I made I was using acrylic squares, but with the heat and humidity they quickly started to warp. It seems like a lot of people use acrylic and don't have this problem though. Is there a certain thickness I should be going for or a specific type?
The hexagon is 5.5 inches in diameter, but as you can imagine it's not easy to find glass cut to that dimension. I may have to finally try my hand at cutting glass, but it might not be wise to try and do a hexagon for my first attempt so it might be a while before I get around to cutting glass for that. I suppose I could also just let the glass hang over.
This was also my first attempt at a vertical nest, and I'm pretty happy with how it turned out. At first I thought it was ruined because on the initial pour some of the casting material got underneath the water tower and pushed it up despite having a rock on top of it. I decided to just continue with the water tower setting on top of the perfect cast as it hardened and see how it turned out, and it actually ended up creating a lot of visibility for the water tower's capacity so I guess that's a plus, and its still stuck nicely into the casting material.
On the second pour some of the casting material leaked into the sand I had placed to mold the chambers because it wasn't packed down hard enough. From the front view it looked like it was going to be ruined, but luckily it was only on the front and I was able to easily break off the small pieces to expose the hollow center. Whew!
Its probably also a bit too deep to have only one viewable side. I may end up making the other side viewable next time as well if I use that same mold. Also, I had to make the bottom layer very thick to accommodate the magnet placement using the mold as it wasn't super flexible in where it allowed me to place them. I probably should also make the stalactites shorter and a bit more random looking. All in all though, considering everything that went wrong, I'm glad it at least turned out as well as it has.
Unfortunately, after cleaning the sand out of the vertical nest, I noticed that the water tower mesh came undone on the front left part (seen above). Does anyone have an idea how to fix this? I'm assuming some silicone would work? I'm guessing I damaged it when cleaning the sand out with the plastic spoon. I should probably just use water next time to remove the sand.
