The bridge is, I believe, an adaptation of Doug and Blackmachine's method for his F8. The only parts that were not 'off the shelf' I believe are the tuners, and that's only because the standard locking Sperzels didn't have an aperture wide enough to fit the bottom string through! When Wez called them up, they sent out a custom set with pre-drilled holes large enough for the low strings (up to about 75ish I guess?) for a *very* reasonable price. Excellent customer service, there :)
Aside from that, the maths for where the bridge and nut go, at what angles, where your parallel point is (in this case, it's the 7th fret, but it could in theory be anywhere) is reasonably straightforward, but the exact placement of all of these (and of course the frets!) is of course more complicated than on a non fanned-fret build. It is, I've no doubt, a lot more work, but the result is a wonderfully articulate and piano-like tone on the cleans, and brutal attack when pushed.
I'm sure Wez will answer your questions much more accurately and succinctly than I can, though!
