The hexagons and some of the other polygons have pretty small radii, which I take to mean require small tooling (imagining a router/mill type tool) in contrast with the long straight channels with a larger radius. Then that small tool has to be changed out to a larger one for the big areas of removal or run for longer to remove that material. Can anyone speak to why a more complicated (seemingly) design was chosen for the chambered backs? Curious about the whole enchilada - sound, weight, strength, production cost/time. Very interested in the process. Any insights appreciated.

The CNC router changes bits on its own, with no human interaction. It grabs whatever bit it needs, and goes to work. As you watch the clips in the video you will see several different bits in use. Those were all changed by the machine. The only time human hands touch the CNC process is to flip the body over.
The honey comb rout pattern was developed to offer the best "weight reduction to stability ratio". All bodies will eventually move to a similar pattern. There is nothing wrong at all with the longer, larger chambers, but as always, Warmoth is trying to improve and refine our process and techniques. I can tell you one big advantage for Warmoth employees: when the bits hog out those long chambers it is LOUD. The honeycomb pattern is much quieter. It's so much easier to take naps now.
As far as weight....25% weight reduction is the
minimum. On some bodies the percentage will be more...especially if the body style is large. This is because they have even more total area to remove weight from. For example, I held a chambered Nomad body yesterday that felt like balsa wood, it was so light. It was crazy. It must have been 3 lbs.
Sound-wise, I don't feel like the sound difference between a solid body and a chambered body varies any more than the variation between different solid bodies of the same wood/style. I know other players who disagree with me, and say they feel chambered bodies are more airy and open sounding. I'm not sure who is right. Maybe we both are, based on our different experiences. The truth is, there is no math equation that can correctly tell what a given body will sound like. The only way to know is to build it up and play it. That's why it's so awesome that Warmoth currently offers the 30 day return policy on chambered bodies. You can buy one and hear it/play it in the real world, and decide for yourself.
