Had to take me to the last detail of the chain that I haven't experimented with yet, the stable. The stable is an important tonal detail and I really like the sound of spruce! The problem is that the stable is subjected to great forces, so the whole stable cannot be spruce. As always when I solve a problem, the actual design comes into place as I make, no drawings here not 🙂
Made a variation on Stewmac's standard pyramid figures in ebony.
Started by gluing together a "cross veneer" of two 5 mm thick spruce boards. At each string hole I inserted a 3 mm thick rectangle of rosewood with the grain across the hole to prevent the string from digging into it. To give the stable leg a solid piece of rosewood at the top and also a thinner piece of rosewood at the other end. Left a couple of mm fir under the last two pieces. In order not to mushroom to the stop for the string ball, I drilled dowels into birch on the underside through approx. 5 mm spruce. Glued with skin glue between the spruce pieces and the pieces around the string holes, epoxy to fill in the most difficult fitting pieces on the front and back and super glue for the birch plugs. Maybe I'll possibly drill three 3mm round rods into the side between the back and front rosewood plate to keep the stall from splitting in the middle as planned, feels like it would be strong enough as it is.
The stable must be painted black before mounting in place. To be mounted on my local guitar that needs updating, may take a while. Want to test if it holds for the string even in the long term, but I think it is strong enough. Should be interesting to test!
The weight of the ebony figure is 26,9 grams but only 15,8 for the spruce figure.
