(first image in the previous post seems to be broken, so here it is again)
Anyway, here's the little DIY update this week!
I created two new formicariums this week, one by carving chambers into a block of Ultracal, making an all in one setup like the test I did before, and another one made by molding chambers out of clay and then pouring the Ultracal over it. Both turned out pretty good imo, especially for first attempts. I didn't take pics of every step of the process, but I'll upload those I did take.
Here's how I made the first one. I started with this container, an mDesign something or other off Amazon. I got a four pack, so I can experiment if I want.
(I really need to clean up my workspace...)
Then I mixed up my plaster and poured it in. I didn't fill as much as I wanted to, so I had to quickly mix up more and add it. I still used a ton of Ultracal for this nest though. In the future, I might want to fill the unused volume with a box or something, just to cut down on how much is needed. I coated the inside of the plastic box with a little bit of vegetable oil before this, to hopefully make removing easier.
Anyway, once it was poured, I added some fake plants and stones to the top. I was worried that the stones would just sink down, but it seemed I made it thick enough to support them... if only just. I was also worried the plant was too big and would create an escape route, but I think it'll be okay.
Next, I sprinkled some crushed gravel, and then some coarse sand over top. I went from biggest objects to smallest, so it would fill in the spaces between and everything would be securely stuck.
Here's how it looked at this point. I do wish the container was taller, as I feel like I didn't have a lot of space for the nest, and the walls of the outworld were pretty short as well. I left this to set overnight.
The next day I removed the solid Ultracal. It was not easy,
but after a few solid thwacks it came out.
I had dumped all the loose gravel and sand off the top, leaving only the stuff stuck in. This was now a natural looking diorama.
Next I sketched out a design and began to carve. I started by drilling holes with a large bit to remove most of the material, which did not go as smoothly as I hoped. My drill would never quite go where I wanted, and if it were too close to the next hole over, it would just slide to follow that one. So my rectangular hole for the sponge ended up looking like... this. After drilling, I would remove the remaining plaster and shape the chamber using a rotary carving tool.
It was very dusty.
After a little while, I got most of the main chambers and tunnels carved out. I had a little more planning to do, so I took a break at this point. Again, not perfect, but going pretty well~
Next, I drilled holes in the lid of the container using the largest size step drill I had, and cut out circles of my steel mesh to cover them. I used a soldering iron to melt the mesh into the plastic, which worked like a charm. Burned the plastic a little bit so it discolored, so next time I'll turn the heat down.
Then I finished up the carving, including drilling the entrance holes to the surface. As you can see, the idea for this nest is in two parts. The section on the right is what will hold the ants first, while the section on the left is blocked off. Once the colony grows enough to fill those two chambers, I'll unplug the left side to allow them to expand. This way I won't need to connect a bunch of nests together in a network of tubes, or continuously move the colony as they grow. I'll still need to expand at some point, but they'll be able to stay in this nest for longer.
I don't have any pictures of this part, but next I attempted to paint the inside of the chambers with liquid Ultracal, and stick sand to it so the chambers had texture and were more natural. This didn't work so well, as the Ultracal became a thick, dry paste almost immediately and the sand wouldn't stick. Some did though, and I guess I'll live with it. I suppose the ants will probably be able to pull some sand off and have a bit of substrate to play with, which isn't a bad thing.
I cut a PVA sponge to fit the chamber and slid the whole thing back into the container. It was almost as hard to put in as it was to take out. I'm still not sure if I got it all the way to the bottom, but at least it's stuck pretty securely. I drilled a couple holes into the outworld section and added sections of tube for future connections, if needed. Then I drilled a hole to the sponge chamber and filled 'er up. Here is the completed nest. A little messy, but it turned out alright.
On to the second nest I made this week! Some of it was between the steps of the last nest, but I separated them out. I took fewer progress pictures of this one, so it'll be less image heavy.
I got some modeling clay, plexiglass sheets, and this conveniently sized container, and I molded out some chambers, sticking it right to the glass. Not entirely happy with the design, but it'll do.
I also made a water tower by melting some of that steel mesh onto a tea light cup, and poking a tube into the side for easier filling.
I stuck this mesh side down into the clay, and got the tube against the side. I tried to stick it there with hot glue to keep it from filling with plaster, but it didn't work so I just let it be.
Now we were ready for the pour! I put six magnets around the edges of the plexiglass, held in place with magnets under the container. Then I mixed up some more ultracal and carefully poured it over. Again, I didn't quite make enough, so I quickly had to mix more to cover up the bottom of the water tower.
and I let that set overnight.
Some of the plaster did get underneath the glass which I hoped to avoid, but it wasn't much.
I popped the plaster out of the mold and pried out the plexiglass. It was in there pretty good, which was kind of the intention. Next I had to pull the clay out, which was slightly difficult, but once I got it started it was a lot easier.
Once the clay was out, it looked like a proper nest! the screen of the water tower was a bit dirty with stuck clay and plaster, but I think it'll be okay. There were a couple small bubbles, but nothing bad. Success!
Finally, I smoothed out some of the sharp edges with the rotary, and was good to call it done! Almost. I debated for a long time on whether to put the entrance on the sides or the end... Eventually I settled on the end, because that would give me three flat sides to set the nest next to something, instead of just the two.
I also put some sections of tubing in to those for connecters. A very tight fit.
And that's it, two nests finished! I put a temperature/humidity probe into each of them (at least as far as I could) to test how they would be, if they worked well enough for ants to move in. I've still got a few weeks or even months yet before any of my colonies will be even close to big enough to need either of these nests, so I've got plenty of time to see how their conditions settle and redo as needed. I'm not entirely sure how I should heat these either, so that's being tested as well.
And there we have it! My two first official home made formicariums! Certainly not my last. I put this in my journal thread because it was going to be a one-off post, but if you think I should make a new thread somewhere else for these, let me know!
See you next week!
