Double Top Classical Guitar - Redwood/Nomex/Sitka Spruce/Curly Black Walnut, Part 1
In an earlier post, I talked about how I replaced the top of a guitar I had on hand with an all-wood double top as an experiment. The new top was an improvement, it was very loud and strong, but its voice, to my ears and aesthetic, was lacking in beauty. I mentioned this in a text to a guitar maker I know in Brazil, he replied that he had made a similar double top and found that it "lacked resonance". After playing the guitar for several weeks I made the decision to replace the top yet again, but this time with a “standard” double top that has a honeycomb Nomex core. The top is redwood and the inner veneer is Sitka spruce. Here is a link for more information on double top guitars.
I used Sitka spruce veneer to cover the Nomex and redwood top. After the glue has set, I sanded down the honeycomb material level with the top, graduated the top so that after I glued on the Sitka spruce veneer I could graduate the thickness of the tops edges to about 2.0mm, the area under the bridge to about 2.5mm and most of the upper bout to about 2.7mm.
