Jared helped out a lot on this one by drilling all the holes, which was mostly a challenge
in eyeballing "straight and centered" using a drill press where no two pieces were exactly
parallel and nothing was quite level. While he was working on each riser, I tapped the holes
in the other riser so the bolts would simply thread in.
To get this done I just needed the appropriate taps, a tap wrench, etc... Oh, and a thread
comb so I could identify the thread spec of the bolts I needed to match in the first place.
Here's all the information you could need about threads, fasteners, tap hole bit sizes, etc,
(metric and imperial):

With the risers on and tank in place, here's how the cockpit is looking:
