I've just finished making a "Buachaill Mór" guitar to be raffled at the Halifax meeting of the 10th Anniversary Meeting of the Acoustic Soundboard Forum in Halifax this September (see this thread for more details) with a Lutz spruce top and Mahogany back, sides and neck reclaimed from a chest of drawers bought in the British Heart Foundation High Wycombe shop. Parts and plans:   Here's what the chest of drawers looked like:  The Mahogany sides are thicknessed. The bass side will have a “porthole” soundport just up from the waist on the lower bout and the hole is drilled with a 40mm Forstner bit:  For bending a mahogany disc is used to plug the hole:  The sides are then bent in the Fox-style bender using a heating blanket. The cutaway is bent on the hot pipe:  Here are the bent sides are in the mould:  |

The Claro Walnut back plate and porthole insert are glued together using hot hide glue:  The porthole is then drilled out using a 32mm Forstner bit:  The completed porthole is then glued into the bass side using fish glue:  Here’s the result:  |

Wonderful! As I said the other day, there are some talented people on this forum. And now, as then, I speak mainly of the guitar builders  . |

The mahogany neck block is drilled for the bolt holes. The side of the neck block that joins the cutaway has been shaped to fit the side:  Next the holes for the 6mm carbon fibre flying buttress rods are drilled:  The slot for the fingerboard extension support is cut and the fingerboard support is then fitted and glued in using hot hide glue:  Two Claro Walnut strips matching the binding are glued to the front and edge of the treble side of the neck block. The neck block is then glued to the cutaway side together with a black/ pear/ black purfling strip in between the side and Claro Walnut strip using fish glue:  |

One day, I keep promising myself, I'll remember to try your method of gluing the tail graft in before closing the box!

The sides are profiled for the back’s curvature and to build in the “wedge” that makes the sides narrower on the bass side:  The back Sapele reverse-kerfed linings are glued in using fish glue:  The sides are profiled for the top’s curvature and the linings are glued in using fish glue:  The mahogany side braces are notched into the linings and glued in using hot hide glue:  The 6mm carbon fibre rod flying-buttress braces are then glued in:  Here’s the completed rim-set:  |

Tell me Dave, is the hole in the table where you went too far when drilling the sideport hole?  The Mahogany back plates are initially thicknessed, jointed and glued using hot hide glue and the tent method:  The European spruce X braces are profiled to a 10’ radius, notched and then glued on one at a time:   Then the ladder braces are glued on:   The Claro Walnut X brace cap is glued on using hot hide glue:  The back braces are then carved and the back is “voiced” – here’s the result:  |

The Lutz spruce top plates are initially thicknessed, jointed and glued using hot hide glue and the tent method:  The soundhole is going to be “bound” with Mahogany. Firstly the rosette is routed out:   Then a Mahogany soundhole patch is cut to shape and glued on using hot hide glue and a caul:  |

Then a rosette channel is cut in the top down to the soundhole patch:  The Mahogany rosette ring and black/ pear/ black outer purfling are test fitted and glued in using white pva glue:  Next a step is routed in the inner edge of the rosette and then the soundhole is routed out. This gives the look of a totally bound soundhole and the fingerboard edge will finish at the beginning of the step to give a complete Mahogany ring around the inner edge of the soundhole:   The top is then cut close to the final shape:  |
