What little gaming I have been doing has involved 2mm armies. I started thinking of using Battle Cry scenarios on a grid board. However, I didn't have enough terrain pieces. There is no shortage of wooded terrain pieces, however, I lacked hills. The price for hills are around $2.00 a piece from Irregular. Right now money is tight, so that was not an option. I then thought, why not make my own? And while I like the Irregular terrain pieces, the hills from Irregular makes it hard to deploy forces on them. I decided to make my own mold. So before going to work, using some clay I made a small hill that was flat enough to deploy a 4 piece unit on it. I then mixed the rubber to make a one piece mold. By the time I got home from work the mold would be ready to use.
When I got home the mold was indeed ready to use. I poured the first hill and was happy with the result. After the second hill it dawned on me how much metal my mold used. And at $5.00 a ingot, I was going trough quite a bit of metal. I switched to my scrap metal, to save my good casting metal. On the third pouring, I spelt some metal on the work board. After it solidified, before it went back into the pot, I realized that it looked like a nice little hill. I poured a few more spots of metal on the work board and using a wood stick, could shape the hill. I stopped using my mold and made a couple of more hills this way. They saved quite a lot of metal, and look better than the molded hills. I plan to pour some more soon; maybe even try to make them stackable to make different level hills. I went trough approximately 3 ingots of metal, enough for at least 7 Irregular hills. Maybe I didn't save too much money doing it myself.
I wish I could provide some photographs, however I misplaced my card reader and the SD card I use for my gaming.
