And some props to Peter in there, too. The second I saw the plate I instantly thought about the Marreiros all-wood double top.

Almost pretty enough to be on the outside. I would not want to make all those holes without the benefit of CNC, machines certainly take out the monotony of these kind of tasks.

Brings to mind his talk at AISA last year. He said that he wouldn't add anything to one of his guitars unless it has a "Wow factor". Seems he found something!

yep,

and these guys have been doing it for about 10 years now:

Sergei DeJonge made some double tops using a spruce core. He cut them out with an X-Acto knife; a bit more time-consuming than what Kevin's doing. From what I understand, though, the time factor was not what caused him to stop making them. He had the grain of all three layers running along the top, and they had too much tendancy to split.

When I talked to Kevin at the Healdsburg guitar festival about these plates I asked him if he laser cut them. He said that all the braces and the plate were laser cut. They look even better in real life!!

Hmm... Does he still do final brace tuning for each top or are they cookie cutter?

I love a good challenge!

Yea, kinda show-offy with all the laser lettering and such (reminds me of multi color back strips or side bracing), but I like the idea of the elimination of the tone bars and I'm already thinking of the bridge patch on ladders and no bottom ladder. I like the idea of no Nomex...keeping it wood. Can't see it as anything like a doubletop, more of a lightweight, oversize bridge plate.

It is a little flashy looking, especially for something inside the box. But functionally, I think it's a great idea. Pretty much a more advanced version of what I've been pondering lately, using spruce for a bridge plate. I was thinking of making a relatively large, round bottomed plate, thick under the bridge and feathering the thickness out. But that would basically be a semi-laminated top, whereas the Ryan version mimics a double top.

The lack of tone bars is definitely interesting. I'd planned on still putting some sort of braces down there, regular tone bars or a lattice. At the moment I'm leaning more toward something along the lines of Brock's average size hardwood plate with lattice intersecting it. Or smaller spruce plate + lattice. But then the weight advantage of spruce may not matter. Little tempted to try the Ryan style now, although I may go crazy by the end of drilling that many holes, and it seems a lot less tune-able than conventional braces.

What? You don't have a laser cutter?
I just laid it out for a forstner bit and it's only 72 holes. Drill 'em into a 2" block of spruce and you have lots of bridge patches.

Twenty minutes to lay out a 124 hole jig, 1 hr to drill the holes. Each slice is enough for a ladder GC or 2 Larson X brace. Plus I have the jig.
