A thing that Apple did in Mac Pro gleefully nicknamed the cheese grater is that they used a ball end mill not a flat end mill. Your results are super cool, it kinda looks like it has a resonant chamber there. The Apple one is more flowing though. Just wanted to share so that maybe you'll use it for future experiments.

There's just a hint of overworking the strings in most of the limited playing I've seen (or it could just be a recording thing, engineered for speech), as in hitting it harder than what suits the music. It just feels like his playing style lends itself for some unyielding metal instead of what he usually plays.

It broke dad's heart but I still play and own the drums that replaced my clarinet. I hope your efforts are rewarded and your daughter learns and enjoys the fruits of her father's occupation. :)

[@evilcowboy]

lol at least your dad was somewhat supportive, my mom told me I would never play guitar any good, I can't sing because I wasn't born with the talent to do so. And yes she said it like that, thinking it was tough love and not discouragement. Today she is eating her words since I can pop off the Serrana Arpeggios from Jason Becker, and I can now sing Micro Cuts by Muse (very hard song to sing, if you've heard it you will know why) and my current useble (meaning I can form words at that pitch) vocal range sits at a C2 - B6. I just didn't listen when she told me that. She had never heard me play or sing when she said it that was the real kicker.

[@HorrorMakesUsHappy]

Can I offer a possible word of advice to you as a father? My father plays. In 9th grade I took an interest in learning. He bought me a guitar and some books. I fumbled with them a few months, then quit. My freshman year of college Enter Sandman came out, my roommate said if I bought the tab book he could teach me how to read it. Over break I was home practicing the songs off that album, when my father, annoyed by their simple repetition, finally said, "Why don't you learn to play something else??" I threw it back at him: "Why don't you teach me something else??" So he taught me Stairway. And then many more songs after that. Years later I realized - I didn't want to learn how to play guitar. I wanted to learn how to play _from my dad_. Maybe your daughter doesn't want to learn. Maybe she wants to learn - from you.

[@jamcam9]

Man, a fretless bass with this would be dreamy.

[@bigk4755]

The effect of the overlapping holes front and back is really cool. Makes the body appear to be hollow. I am curious as to how you treat all of those sharp edges. So here is my suggestion. In my woodworking I hate sharp edges and corners (due to chipping and the finish wearing off of those sharp corners) so I keep a 1/16” round over router bit loaded in a small trim router (with the offset base). I find that little round over is hardly noticeable and much nicer to the touch. You will still have to quickly touch that little round with a piece of 150 grit sandpaper, but that goes really quickly. My guess is that you have removed 2.7 lbs/1226 grams of material. And I am betting that your daughter will be absolutely thrilled with her “new”, and very unique, axe. One of these days I am going to have to try my hand at building a guitar.

[@amirkhalid5449]

True story: A colleague at work once showed me an electric guitar with many holes drilled through its body in a similar fashion. "Is this not a COOL guitar?" he said. After a little thought, I replied unto him, "It's certainly well-ventilated."

Greetings from South Florida USA. This is the first time I've seen open chambering on a guitar body. It's usually hidden under a 1/4" (7mm) top. My only caution is when you do the refinishing.

I think that to make a guitar lighter I would start by routing out most of the area that is covered by the scratch plate - that being the low hanging fruit in this case as that material would not be missed from a visual aspect. A new scratch plate that could cover a wider area such as the top and bottom horn (as seen in guitars like the Burns Bison) would allow this hollowed area to be extended. In other guitar designs such as an LP style where the guitar would not have a scratch plate I would be tempted to use a band saw to completely remove the top allowing me to route out the majority of the body area below where said top sits before gluing it back on. I have no idea how well this would work, but then I am a hobbyist going through a thought exercise.

My last guitar that I built was over 12 lb before I was finished I had cut the tree down years before and had cut a number of boards out for different projects I loved the grain and brown , red , green and orange colors as I had made it out of Hedge Apple ( Osage Orange ) To make the guitar a more manageable weight I used a milling machine to remove a LOT of wood from the back I left the front untouched On the back I put a veneer that came from the next board from the same log This allowed it to look like 1 piece of wood But I ended up with a guitar that weighted just over 8 lb I was thinking you might have used that to remove the weight
