4 string bass ( jpdc) continued : neck construction part 1

Now that the preparation of the neck blank has been done , I can continue routing and and cutting out the neck using different machinery and hand tools .

Routing the truss rod channel and two 6mm
round bottom channels for carbon rods
using an old Hitachi MV 12

Test fitting truss rod and carbon rod

Cutting out the headstock shape on the bandsaw

A template is used to mark
the outline and holes of the headstock

The rough result

laying out the neck shape on the blank

Cutting the rough shape of the neck
on my small INCA bandsaw

Some wood to waste.
The leftovers will be used in another project

Hollow carbon tubes with a beech
dowel glued in over the entire length .

This gives me a nice rigid stabilizing rod.

The rods are glued in with epoxy and
the lmii truss rod is installed with a bit
of silicone for anti vibration

I needed to rout a small recess
for the truss rod adjustement cover .

I used a ball bearing router bit and template to do this

The result , hidden corners cut with a chisel

A great Bosch router

Template routing of the headstock.
I use an old router bit that is actually a rasp with a bearing on top .
This avoids tearout on this wavy grained birdseye maple neck.
Sometimes I get light burn marks , but these can easily be sanded out .
