I'm building a guitar for a guy now in the 'spirit' of his '34 martin. It will be BRW back/sides Torrified Red Spruce top. It's not a direct copy of it as he's letting me have my way with the top but he did measure his guitar and sent me the specs for purpose of reference. He used one of those Hacklinger thickness gauge measuring devices.

Spruce top: 3.2mm (.127in) thick
Brazilian rosewood back: 2.55 (.1in) mm thick
Brazilian sides: 1.6mm (.063in) thick

.06in for the sides? Does anyone have any experience using those gauges and can attest to their accuracy? Seems a bit on the thin side to me. That's 1/16th inch thick, not unheard of for a Flamenco guitar I suppose.

Did he measure in multiple locations? It may have gotten a lot of block sanding/scraping; the starting thickness was probably thicker.

Thin sides not unusual in older Martins I believe.
Even had a 00-18 in for repair recently, very lightly built.

Top sounds too thick to me and the sides a little on the thin side.

Good question about measuring more then once, I'm not sure about that. He also said it was the lightest guitar he's ever held too.
