The neck will be attached to the body using three M6 bolts and will be “adjustable” to change the neck angle and string action height under string tension. The three bolt holes are marked on the back of the body and the recesses for the bolt heads drilled with an 11mm drill:  The bolt holes are then drilled through using a 7mm drill:  The third bolt will act as a securing bolt – it will go through a threaded inserts and the end of the bolt will be tightened onto a copper insert in the neck. An 8mm hole is drilled from the top of the neck pocket for the threaded insert:  The threaded insert is then installed:  The other two bolts will go into threaded inserts in the neck – the middle bolt being “captured” in the body which is used to adjust the neck angle. The neck threaded insert positions are marked and drilled and the threaded inserts installed:  Here’s the neck attached with the three M6 bolts installed. A brass cap will be installed over the last two bolts on the rear of the body “capturing” the middle one:  Here’s a side view showing the neck angle:  Here’s a front view:  |

Leo and Colan - thanks. Are you going to make a bow for it, Dave ? Bow making is beyond my scope and I haven't got time to do the apprenticeship before Christmas so it will be a bought one. |

Garn, you just need a suitably bent twig and five minutes with the neighbour's 'oss. You professionals are sooooooo fussy  |

No yogurt pots, washing up squeezey bottles or sticky-back plastic?!!  But you're right - that design seems really good! Keith |

Thanks Andrew. It's Becky's eub so she does the naming and hasn't decided yet. I'll let her know your idea.

The pocket for the cover plate is routed:  Here it is after tidying up with a chisel:  I decided to use an ebony cover plate rather than brass and it is drilled at each end using a 5mm drill for the brass M5 bolts that will attach it:  The central two holes for reaching the adjusting bolts are then drilled with an 8mm drill:  The two threaded inserts for the M5 bolts are installed in the body:  Given that the string tension will be 250lbs I decided to add a central bolt for the cover plate. Here’s the cover plate test fitted:  A piece of ¼” brass rod is epoxied into the neck where the stopping bolt is. When the epoxy dries it will be filed flush with the neck:  |

The string holes are marked on the body and drilled through using a ¼” drill:  The recess for the strings is then routed on the rear of the body:  Here’s the result after tidying up with a chisel:  A piece of ebony will be used for the ball ends of the strings to rest on. This is glued into the recess using fish glue:  The string holes are then drilled through the ebony strip and are then reamed on the top of the body for tuner bushes to be fitted after the body has been sprayed:  The recess edges are then bound with Etimoe strips. Finally the ebony cover plate is bound with Etimoe:  |
