As well as building the Prize electric I've also started work on a Cuban Mahogany and Lutz spruce OM. This will also be coming up to Halifax, but don't get excited as it's already spoken for.
B&S: Cuban Mahogany Top: Lutz Spruce Neck: Mahogany binding and head plate: Ziricote Fingerboard and Bridge: Bog Oak
This, unusually for me, will probably be a flat head, but then again.....
My usual laminated linings are made. As you can see I made five linings for this one, as I made a cock up on one with the layers the wrong way round.
Sides are bent and profiled, then the head and tail block are glued in place, the linings are glued in and the rim set is then sanded to profile in my sanding dishes.
The back is joined cut to rough plantilla and the braces glued in place. The braces are inlet into the linings.
Colin

Time to prepare the top plate. The Lutz plate is jointed and then joined using hot hide glue and the tent method. For those of you that don't know Lutz is a naturally ocurring hybrid spruce between White Spruce and Sitka Spruce. This particular plate is probably the best North American spruce I have ever found.  Next job is to install the rosette, first I draw the template on the guitar, measure 147mm down from the top and drill a hole for the pin.  The channel is routed and the rosette of b/pear/b and Ziricote is glued in.  The plate is sanded to near final thickness, and the bracing pattern is drawn on the back, I do this before I cut out the soundhole as I use the centre of the soundhole to reference the layout and it's easier with just the small centre hole.  Finally the soundhole is cut out.   Colin |

Thanks Francis, always a relief when the rosette is done, routing channels in a hundred quid bit of wood is always verging on the brown trouser isn't it.

Bracing of the soundboard is next. My braces are all inlet to each other forming a single structure. After preparing the rough European spruce braces and cutting all the little mortice and tenon joints the braces are glued on to the soundboard using Hot Hide glue in the go-bar deck. The upper transverse brace will be added later.
Lots of carving to do next.

A bit of first order brace carving before gluing on the remaining braces and Padouk bridge plate.   Should get the top voiced tomorrow, then it'll be time to close the box. Colin |

After much tapping and carving the top is now as good as I'm likely to get it, so the braces were then inlet to the linings and head block and it's ready to be glued on to the rims.  Colin |

Label glued in and then time to close the box. Fish glue and a go-bar deck take care of the latter. Never to be opened again until they restore the guitar for the Victoria and Albert Museum retrospective exhibition of my work in 2150 to celebrate 200 years since my birth.  Colin |

The last of the slightly nervy jobs done the binding has been installed. First I rout out the channels for the binding and the purfling.  Next I glue in with fish glue the top purfling of Cuban mahogany and B/pear/B.  When that's dry I check the binding fit and adjust where needed and glue the Ziricote binding in again with fish glue, when dry the bindings are planed and scraped level with the top and sides.     Neck next and the decision on flat head or slot head, flat I think for a change. Colin |

Forget all of the current political shenanigans, the subject on everyone's mind has been "Will it be a flat head or slothead?". Well decision made, it's a FLATHEAD! I had a set of Gotoh flathead tuners on the shelf, so easy choice. My standard scarfed mahogany neck is put together and the carbon rods and truss rod are installed, before I glue on the stacked heel I need to establish the neck angle, so I use my adjustable guide on the body of the guitar.  Guess what it's 1.5deg, it's always 1.5deg, of course the day I don't measure it......  The neck extension is cut to thickness and the stack heel glued in place and a Ziricote head plate glued on. When dry the neck is cut to rough shape on the bandsaw and the head shaped, I had my 'gibsony' template handy, so that's what it gets.  The neck heel and shaft are 90% shaped and it's 1 o'clock and time for lunch, 'dum-di-dum-di-dum-dum'. (for all of you early Genesis fans out there).   |
