Well I've finalized the geometry of the tank. If there wasn't a deadline to this build off I'm sure I could think of another 100 ways to tweak this thing but enough is enough. Overall it's gotten quite a bit curvier than when I last posted images. It looked good before but I think it looks better now. I guess you could say it went from "Keira Knightley" to "Sophia Vergara." sweet tank bro !!
I'm still working on getting some CNC time, and while I'm waiting I have to finish up how I plan to mount this thing. The plan is to go through the bottom and possibly use some strong magnets in order to avoid visible screws. Below is a quick photoshop of the tank on the bike, as well as the potential location for the seat.
