Had a hot build on my bench tonight. Looks like I've achieved the impossible, once again. Yaaaawn... Two of those coils would result in a 10.92k humbucker and and you can see from the following photo, there's even more room for wire. The bobbin isn't completely full yet. Also, note that I run a full turn of 7 strand AWG 20 black hookup wire wrapped around the bobbin, inside the coil, just like Gibson did (and another turn around the outside of the coil). This inside wire, along with its solder connection and tape insulation, takes up quite a bit of coil room. If I skipped that, like most modern builders including Gibson do, there would be even more room. No tension, aside from a Whisker Disk of the weakest available size and a little drag through the feeder, was used and the machine was set to a slow speed of rotation with a PAF-correct TPL. Perhaps those who speculate should not doubt those who accomplish?
