It's the Summer Solstice and the longest day - certainly feels like it  European spruce caps are glued over the A frame braces:   Finally the last ladder brace is glued on using hot-hide glue:  Then the "voicing" process starts - the braces are profiled to give the top response I am looking for. This one is a bit tricky to do as the top is thick at around 3.3mm - the top will be sanded later to keep this thickness in the centre and profile down to 2-2.2mm at the edges so I have to have in mind how it will respond then. When the top has been "voiced" to my satisfaction I sign and date it:  Here's the "voiced" top:  The Colombian Rosewood back centre strips are glued in using hot hide glue:  As access through the soundhole will be tight I decided to glue the label in before the top went on:  The K&K transducers are glued onto the underside of the top using superglue gel:  Notches are cut in the linings to fit the top’s brace ends and the top is then glued to the rim-set using fish glue:  |

Then the slots for the two carbon-fibre rods are routed:  The carbon fibre rods with mahogany caps are glued in with fish glue and clamped while the glue dries:  |

The Colombian Rosewood headstock veneer is glued onto the top of the headstock using fish glue:  The Colombian Rosewood veneer is bent to the shape of the volute and glued on the rear of the headstock using fish glue:  The Colombian Rosewood bindings and black / pear/ black side purflings are taped together:  Then they are then bent using this jig:  Here’s the result:  |

The headstock is then cut to shape and the tuner holes are drilled using this jig:   The rebated holes for the tuner inserts are then reamed:  After a bit more shaping of the headstock the Rubner tuners are checked for fit:  Sorry about the pictures - I accidentally set the camera to widescreen - normal service will be resumed as soon as possible  |

Next the top binding channels are cut using the binding jig to the depth of the bindings plus side purflings. The channels are stopped just short of the end-graft. Purfling pieces are stuck using double-sided tape over the end-graft. The binding channel is then cut over the end graft with the jig riding on these so that the depth cut is just that of the binding. The end graft side purflings can then be mitred using a chisel:  The process is repeated on the back:  Next the top and back purfling channels are cut:   Then the top bindings and purflings are then glued on using fish glue:  |

The bindings are then scraped and sanded flush in the Troji and the top is then cut for the floating fingerboard:  A slot for the threaded inserts is routed in the heel and then it is glued on to the neck shaft using hot hide glue:  |
