Started with the fretboard this time:

Then shifted my attention to the neck. Routed the slots for the carbon reinforcement strips plus two spoke wheel truss rods

Sawed the headstock angle.

brooks-exb-12-sa-sawing-headstock-angle_

 


And planed it nice and smooth

brooks-exb-12-sa-headstock-angle_orig.jp

 


Made the truss rod cover

Glued the fretboard onto the (roughly shaped) neck

brooks-exb-12-sa-fretboard-glueing_orig.

 


While that dried took to the mahogany body blank.
First off I routed the controls cavity

brooks-exb-12-sa-controls-cover_orig.jpg

 


Then switched to the other side to route the chambering

brooks-exb-12-sa-tone-chambers_orig.jpg

 


Did some free hand routing for the wiring channel

Before glueing the quilted maple top onto the chambered body I had to saw the tri-angular shaped F-holes

After lots of checking and measuring I finally glued the neck in

brooks-exb-12-sa-neck-glued-in_orig.jpg

 


Then drilled the holes for the controls

brooks-exb-12-sa-drilling-controls-holes

 


And stained the back a dark mahogany (with a dash of red)

brooks-exb-12-sa-staining-back-and-sides

 


The quilted maple top was going to get a cherry burst
First did the yellow stain.

brooks-exb-12-sa-staining-top-yellow_ori

 


And then (while still wet) did the red outline.
And feathered it out to make nice smooth gradient.

brooks-exb-12-sa-staining-top-burst_orig

 


Then built up lots of layers of clear

brooks-exb-12-sa-first-layers-of-clear-b


brooks-exb-12-sa-first-layers-of-clear_o

 


After lots of sanding and polishing I mounted the pickups and hardware

Made a label and glued it in

Cut the top nut (string guide) from a piece of buffalo horn. I used the brass template the ETS provided with the bridge

brooks-exb-12-sa-buffalo-horn-nut_orig.j

 


Mounted the tuners. Had to modify the carbon base plates of the (light weight) Gotoh CXB-01 tuners that I used for the octave strings.
Because the "ears" were overlapping each other.

I love your work.

 

Can I, could I, make a suggestion on the You Tube presentations?  Maybe (maybe) run the bass through a crossover of some sort (Rolls make the SX21) and output the lows through a cleanish bass amp (or something with a bit of whump) and the highs through something with a bit of dirt.  I owned a 12-string for a while, my personal feeling is that the bulk of owners/players are looking for a dUg Pinnick/Tom Petersson tone.
