My new 1963 Hofner Senator bass project


I was kindly gifted a 1963 6 string Hofner 455 6 string guitar by Nev Claughton, Mr Music Nelson.
I chose to convert it to a Senator bass.

The 1963 Hofner 455. I told the donor that I did not want
the hardware.

The guitar was in reasonable condition considering its age,
a few scratches and dings here and there.


The bare patch on the back was where some damage had
occurred. I repaired the binding where it had been knocked off.

My binding repair.

After assessing the neck and measuring it at the nut I found
that the nut width was suitable as a bass nut width. I chose 
to remove the neck and extend it to a 30 inch bass scale
and extend it with a scarf joint at the neck heel.
This is the bass that I wanted a good replica of.

The bass on the right is the model that I'm building
there are a couple of key differences. My bass is 80mm
deep in the body, the Senator was built with a 50mm
body depth. The brochure shows the Selmer model
released into the UK market. My headstock is closer to
the 1963-64 release featuring an inlaid mother of toilet seat
dagger inlay and a 3D Hofner logo. 


The beginning of the neck extension.

I cut the existing heel off the neck and moved it down to
the new location on the spliced neck extension. I drilled
for a mahogany dowel into the heel to stabilise the graft.
I overlaid a maple veneer  on the head stock to cover the
6 plugged tuner holes.

I fabricated a truss rod out of 5 mm high tensile steel threaded
rod. i slipped a piece of shrink wrap over the thread.
the black plastic headstock overlay is inlaid with the
Hofner dagger motif.


This is the Artist 185 Brokat bass that I chose as a donor
for all the genuine 1963 parts that I wanted.


My 1:1 scale drawing of the Hofner saddle.


I fabricated the saddle from Kwila decking wood.
the frets are left over from my fret job and the white stripes
are remnants of the neck binding.








The finger board is made from Purple heart. I cut the fret
slots using the spacing from a Stew Mac, online calculator.
22 frets over a 30 inch scale length.





Fretted and ready for the neck to be glued in. I bound
the neck in white ABS. i used 3 mm faux tortoise shell
knitting needles as side dot markers. They look suitably
vintage.

The masking tape lines helped me to align the neck.

The Hofner logo was cast in resin from the donor bass.
The tuning machines were also from the donor bass.
because they were 4 inline I had to remove the spindles 
and rotate 2 of them to fit on the right hand side of the
headstock. The nut is made from two laminations of bone
and one of ebony.

Here I'm fabricating the tail piece using piano wire, brass
sheet and an old gibson string anchor. The assembly is
hard soldered together.

Test fitting, its too long, some minor adjustments to be made.

Now for painting. the binding is masked with lining tape.

The tape comes off.



Another test fit.


A truss rod cover is made and fitted.

I blacked out the finger board with back stain.

A set of D'Addario Chrome strings to see how it plays.

A test fit od pickup ring and knobs.

The Nova-sonic humbucker pickup came from the donor
bass, it needed rewinding which was expertly achieved by Glyn Evans, Mr Glyn.

Wow it sounds great!

A new set of medium scale D'Addario chrome stings and it's
ready to become my main playing bass, a compliment to my
other self built Antoria guitar/bass conversion.
