Go to the "DIY Projects and Ideas" section, then go to "DIY tanks." There are multiple that you can look through and see what the people did. I haven't built my own tank YET, but I have learned a lot just from following other people's builds. Also, most of the people building don't mind answering questions, but try not to repeat questions or ask for information that is already provided. Just take some time looking through the threads in DIY tanks and you should have a pretty good head start.
