I actually got back to work on #018 yesterday! It felt good. My feet and ankles aren't completely healed, still hobbling around slowly. But the work on #018 is mostly sitting down at the assembly bench.
Test fitting the newly-redesigned pickups in #018's pickup cavity:

Here's the treble side of the new pickup mounted down in the cavity. I worked out a combination of longer screws and stacks of brass washers to get the adjustment working in the right range.

Here it is adjusted all the way down. The straightedge is resting on the fingerboard. The pickup surface is down almost 1/8" below the straightedge. That's good for the range of travel. Normal setup is with the pickup just touching the straightedge. The ebony cap should be flush with the fingerboard for the optimal sound. Then either side can be lowered and tilted a little bit, if needed, to even out the string-to-string levels.
This all looks good, and I think I can declare this engineering problem solved! Tomorrow I'll be wiring up the pickup halves and mounting them, and checking the fit of the pickguard. Then I'm going to get #018 all reassembled, finish up a few little details, and string it up. Give it a good test run.
If all tests out well, then I'll pull it apart again and make the corrections to the paint on the body. Then back together, test again, and off to Ed!
