"Buachaill Mór" Dave has begun work on one of his outstanding 'Big Boy' guitars as part of a deal to help further the career of a Scouse Bard and I just can't wait!!. This was discussed at Halifax (dangerous place, that!) and is now beginning to take shape.
Avid readers of Dave's excellent website will probably have noticed this already, and although I wanted to wait to share it on here until it was further along the line, I can't delay any longer  It will have a Caucasian Spruce top and Old Cuban Mahogany back and sides reclaimed from a Georgian drop leaf table.
Piccies as below:
 Cunning plans...

Back and sides set:

The Cuban Mahogany sides are thicknessed: The bass side will have a "porthole" soundport just up from the waist on the lower bout. The hole is drilled with a 40mm Forstner bit:
 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 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 Rio Rosewood 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 Old Rio Rosewood strip using fish glue:

 Here's the rim-set in the mould: 
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 Mahogany reverse-kerfed linings are then glued in using fish glue:
 The sides are profiled for the top’s curvature and the linings are glued in using fish glue:

Hey Martin, That was my table, it dates to about 1820, so should be well seasoned by now! I bought it at auction quite a few years ago, but didn't have the heart to cut it up, so it has sat in pieces in my loft for about 15 years until I came to clearing the house prior to our move. It was either take it with me or cut it up, so eventually I got round to resawing it and got four sets which I gave to davewhite with all of my other wood. I'd just jet washed the patio before taking the photo, doesn't it look clean! I think the Caucasian might be from my old stash as well, glad it's all being put to good use. Colin |

Back up and running with this build now - getting to look like a guitar and I just can't wait to see it develop!  The Cuban 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.
  Here's the second one being glued.
Then the bottom ladder brace is glued on . . .
