vacuum... as in the green bag is air tight and you attach a vacuum to an opening to suck all air out creating pressure- thus pressing the cf into the body?

Or a foam core with a fiberglass skin, maybe even most of the neck, with a one inch maple core, similar to a surfboard? The core would be just wide enough for a truss rod........ Then some type of synthetic fretboard? Hmmmmm. Not trying to pirate this thread or nothin, just throwing the idea out there.

Subbed mainly to see how you deal with routing and such.

You got it. That green bag stretches about 300% and follows the shapes of the vacuumed piece. The bag presses the cf tightly to the core and also presses the excess epoxy out of the laminate. My vacuum pump is made of an recycled refridgerator compressor and vacuum pressure switch. A bit slow air intake but works fine in this.
I'm going to use an acrylic impregnated fretboard. Should be very stable.
Routing goes just like routing wood, cf can be worked with carbide bladed router bits.

I have thought of doing this, but I need to finish my first bass first.

Laminating finished and two filler coats of epoxy added. They will cure over Christmas and then it's time for sanding. After sanding I'm routing slot for trussrod and making the fretboard.



First filler coat on. Second coat made the surface a lot smoother.

so what do you anticipate your bass w/approximately weigh in at?

I haven't weighted the bass yet. When fretboard is glued I'll weight it. It feels quite a lot lighter than similar shaped four stringer.

Some progress. Two filler layers sanded, one more needed. Truss rod slot routed, fretboard slotted and glued. Next it's fretboard sanding and fretting and cavities for pickup and controls before final fill layer.

Fretted weight is 1,95kg. I just leveled and crowned the frets. I may do a test play after I've fitted the headpiece. Can't wait to hear some test sounds. Even acoustic sounds will do.

Looking good, and the weight is amazing. If I played fivers, I'd start saving for when you'll offload this before building the next one...

Test fitted the bridge/tuner and headpiece. I also got to play the bass. Sounds nice acoustically.



Weight of the finished bass will be around 2800g. Feels quite light.

Last epoxy coat added, now it will harden for two days before sanding and routing the cavities. Then it's time for final sanding and painting.

What brand hardware are you using for the tuners and headpiece?

Ets tuner/bridge and Hohner/Steinberger headpiece. Double ball end strings only. Status makes great db strings at quite nice price.
Pickup will be either 10-coil Wal-like or Q-tuner inspired sidewinder, both custom-made in my shop.
