Tank assembly went very fast.  Some parts were deburred previously, while waiting for
parts or tools to arrive, so not every last item needed deburring during this step.
The tanks are very straightforward, although the instructions start to leave out
the detail of what needs dimpling, deburring, and countersinking.  At this point
you should be able to figure it out for yourself.  The tank attach bracket gets
countersunk, and you can basically final drill all the holes, even though the
steps don't tell you to.

For now, I'll let the photos speak for themselves.
