Build Thread: Tahoe Guitars Mahogany/Carpathian 000-12

Here is a build thread for my latest guitar being built by Larry Nair of Tahoe Guitar Co.. It is a 000-12 with figured old growth mahogany back and sides, and a Carpathian spruce top.

The plan was for this guitar to be started around the new year. So I was surprised when Larry called me and asked if, due to a gap in his build schedule, I would mind if he started my guitar early. I thought about it for a billionth of a second, then said "Sure...no problemo."

My goal with this guitar is to have very traditional looking guitar: 000-12 slothead, herringbone rosette and top purfle, pyramid bridge. I am going with a slightly deeper body, modern nut and saddle width, and Martin long scale.

The Carpathian top (Old World Tonewood) was dubbed by Larry and I as "uber spruce"...very light, very stiff along and across the grain, with amazing tap tone.

The back/side set is old growth figured mahogany, called "Fallen Giant" by the folks at Hibdon Hardwood. It is from a large fallen log which was found on the forest floor.

The five-piece neck will be fiddleback mahogany, with walnut and curly maple lams, also from Hibdon.

I will update the thread with pictures as I am able. Enjoy!

From the looks of the materials this should be wonderful guitar; and a 12 fret 000 body is a great body shape.

Out of curiosity, is that flamed mahogany big enough for a one piece neck? Either way, it looks fantastic.

Thank you! :cool:

Yes, that neck blank is large enough for two one-piece necks. That is, the heel, neck and head all being a single piece, rather than stacking the heel and scarfing the head. The neck for this guitar will be laminated lengthwise as indicated above for stability and aesthetics, but not stacked and scarfed.

Thanks for following this thread! :up:

Sides: Profile, Thichness, Bend

Top Brace Carving

Top Edge Thinning

One of the tricks Larry uses during top tuning is to graduate the top thickness. The top is thinned at the edges and then faired (or is it 'fared'?) in to the rest of the top. Thus the top has a wedge-like profile from center to edge in the lower bout, thickest in the middle, gradually getting thinner toward the edges. Typical reduction at the edges is .005"-.010". The amount of thinning is determined by how the top is responding to the brace carving and a good dose of luthier's intuition.

I can tell you this top responded somewhat to brace reductions, but was sounding tight, being a bit "stubborn". Larry had taken the brace heights well below Martin spec (used simply as a reference) and done quite a bit of profiling. Neither of us were surprised as this is a very stiff set of spruce. Nonetheless, it was time for some edge thinning. The resonance bloomed after the edge thinning. Pretty amazing.

The top is marked to indicate areas to be thinned based on thickness measurements.

An index line of the desired depth is routed into the top.

The top is then sanded "into" the index groove (sanding block shown above). Typically a couple of grams of material is removed.

Sweet! It is a good moment...it starts to look like a guitar, with some of the major design elements in place. Soon after the neck is rough fit...closer and closer.

I visit Larry every few weeks. The last two visits were design related....top tuning and neck shaping. More pics to come when I get back home.
