...To anyone who has taken the tour: is the glue applied to the braces by hand or a machine? If by hand, does one person do it or several assemblers at separate work stations? If many workers do that job that might explain why some brace pictures posted by members of their guitars are clean and others aren't. Do they run the braces across a glue roller or paint it on with a brush? Do different top woods need different (or amounts) of glue?...
I had taken the tour twice, but that last time was perhaps 5 years ago so could not comment if the procedure changed.
I recall glue on braces applied by hand. But while I don't recall whether by brush or roller, I know it was fast and
consistent (as in a "measured" application ...heck,
everything done on that production line was measured
consistency!) so it's not a line worker going willy-nilly with a bottle of Elmers. Immediately after glue is applied, it is then put on a vacuum press where a "rubber-like sheet" clamps down the entire top, and air is sucked out like one of those food preservers: this is how the braces stay put while the adhesive sets. The tops are then placed on racks for final curing for who knows how long.
But like anything made on a line (or even hand-made, natch!), one has to establish priorities and put time and energy where the best outcome will see gains. So if "neater" gluing yields no sonic improvement, then making it look better is wasted time and effort, which we all know translates to wasted money on the line. And no one can effectively argue that Taylor's craftsmanship overall suffers, whether in aesthetics nor most of all, tone and playability. So my guess (based entirely on supposition), is "how they choose to glue" is one of a myriad of tradeoffs they have made to yield the best productivity without sacrificing tone or overall build quality. Clearly, I could be completely wrong about this. But given all we know about the ethic of the company and how it has been received by the marketplace clearly indicates that Taylor knows what it is doing, or folks would be taking their wallets elsewhere.
FWIW, I'd rather see neater joints, without doubt, particularly since I'm a persnickety beast when it comes to details. But above this undetectable aesthetic faux pas, I know that the gestalt of the guitar screams out quality. If it did not, I'd be playing something else.
