I adapted my closing clamps with wedge
shaped blocks.  This was necessary as this
is a flat back bass with a tapered shoulder.  
This enables the clamps to sit properly and
spread an even pressure.


Around the neck root of the bass, two long
clamping blocks with two closing clamps
are used to get a good even pressure in
that area.






A series of maple reinforcing patches are

used
.  They are fitted and glued one by
one, ensuring that their shape mirrors the
curve of the rib.

This repair is replicate
d on the shorter
crack on the bottom bass side rib.










Next to tackle the top strut across the back
!

The strut has curled up and popped off the
back at one end.  It has move too much
and would be under too much tension to
just simply glue back into position, it will
need to be removed and replaced.











A new spruce strut is fitted across the back.






To glue the strut into position I once again
I adapt my closing clamps.

This time one wooden block runs across
the top of the front of the instrument and
another across the outside of the back.  
These are clamped together at either end
to provide good support against the
downward pressure of the central clamps


















Once the strut is glued into its position, it is
given its final shape.




With all necessary repairs carried out, the
front is glued back onto the bass.





















The cracks which now have a clean and
level surface are retouched with varnish.





Once the varnish has been retouched a
new bridge is fitted and the instrument is
set up and ready to play.
Crack repairs to an English Chamber Bass.

There are two cracks running across the
top rib o
f the treble side of the instrument.
These cracks have been caused by the
rib
'stress' relieving itself, most likely due to
the timber not being properly seasoned
at
the time of construction, .
The front is removed.
With the instrument apart I can now fully
asses the damage and make a plan of
attack.

As well as the two cracks on the top rib,
there is also a small stress crack on the
bottom bass side rib and the top cross strut
on the back has shrunk and curled
upwards.







First the two cracks are cleaned
, then they
are carefully glued, ensuring that they
come together perfectly in line.

Animal glue is used for all the gluing jobs,
as it is reversible.
