I ****ed up Iron Chunk prices on my server already so I figured I'd release this to the public:
Iron Chunks usually sell for cheap on the CX and you can craft Metal Platforms (3 iron chunks + 3 iron screws) with 0 Architect skill which sell for 16.64 silver. Pretty good profit even at 2-3s per ore chunk. Using an external program to automate this process would be illegal under the ToS so I made an addon with carbine's own API that does it for you. It's even faster than AHK/AutoIt bot could ever be!
The code is on github: https://github.com/tomedws/PlatformsForPlatinum (direct download link). If you find other things to craft for profit it shouldn't be too hard to alter it.
Have fun!
