  1. I wish you were easier to ship to, as I could send a sample for you to hear the ring and feel the slickness of the solid CF after diamond polishing. When you drop it, it sounds like a cross between aluminum and ebony - serious resonance, but at 3mm thick, not really gonna make a difference. When I use the best silicon carbide abrasives (used for glass) to sand it, the discs get dull within seconds, so I used diamond for smoothing and polishing after carbide milling (I sharpen my own carbide - thank god - need to sharpen my carbide a lot with this stuff), if that gives you any idea of abrasion resistance for strings on a fretless. Yes, I sent Knightro a few samples. Never heard back. That was before I made the solid CF. I only sent the resin filled heavy figure quilted. The fiddleback is such a tight, low topography figure that I can form it solid from a two part mold, then mill it flat. The Quilt would require a full 8mm layup of CF in order to mill down to 3mm. Only practical for fingerboards. Then one needs carbide mills for fret slot cutting (or .024" kerf diamond lap blades). I am molding my gold aramid fiber today in the quilt mold - just doubled its size to 33 x 58" to get six guitar bodies from it. Then once I get my order shipped of .021 thick CF, I will be interleafing the gold fiber in between every three layers of CF, and going in my fiddleback / flame mold so when its machined it will create a zebra stripe effect within the 3D curly chatoyancy. Can't wait to see that.
  2. My Les Paul

    Ditto what everyone else said - outstanding work, insane attention to detail. My favorite part is the serrated edges of the leaf inlays.
  3. Beautiful Job, Scott! Most times I prefer bookmatched face panels, but this one piece top really fits the design. As expected, the craftsmanship, finish and design are superb. I wonder if the right rig and distortion could make that play heavy metal. Would be hilarious to see peoples reactions if it could. Or is that sacrilege to such fine class of instrument? I'm sure it will sound great no matter what.
  4. Fret level, crown and polish on the first ever figured carbon fiber fretboard (fingerboard, exactly), with Dichrolam inlays to top it off. Wait til you all see my solid figured carbon fiber stock. Figure goes all the way through, no matter how much radius is machined off. Its so hard that it polishes to gloss without coating. The resonance is insane - sounds like glass when dropped. Got my Kevlar fiber roll in last week - wait til you see the quilt figure in Gold. Gonna do "strafe coating" of Red and blue candy on it. Research my threads and you will know how awesome "strafe coating" is.
  5. That explains my love / hate relationship with epoxy. You piss it off and it will kick off way earlier than you expected. All lovy dovy up until it feels a little heat.
  6. Thats exactly what I was thinking. The fine sanded surface of CF is really slick, due to the hardness, and likely micro-crushed fiber ends, acting like velvet. That's what I feel, anyway. That's as close as I get to being in touch with my feelings. Here's a quick full shot of the CF guitar. Its a phone shot for instagram, - still waiting finish it up before I pull out the DSLR.
  7. So a spinoff product of the quilted CF, is the new solid figured CF for fingerboards. Ever notice that when you machine down figured wood, the 3D effect continues regardless how deep? Same with CF. I noticed this after sanding through some small spots on the CF quilt, that was resin-filled. Sanded through the resin, and after topcoating, you can't see the spots at all. So I took this principle further. I used my "fiddleback / flame" mold to press a thick build of the CF, then cut the figure flat. Full 3D figure, but solid carbon fiber. Would be awesome in fingerboards. So, the figure goes all the way through the 1/8" thick laminate, showing its 3D figure regardless of how much is removed during radius machining and final sanding. Fret slots cut great with CNC carbide mills. From my research, carbon fiber fingerboards are used in the market (Washburn), but the only downside is that they don't look any better than ebony, so why use it - until now, thanks to my 3D figured fretboards that now solve the "looks" problem. Nuno Bettencourt uses them and calls them "faster" for whatever reason. They do have insane resonance and are very lightweight, ultra strong, as you can imagine CF to be.
  8. Figured wood T type build

    CA does seem to be the answer, if you can get it cheap enough, cuz you will use a lot. My concern is that it will react with the moisture in the wood, and only penetrate so far (hardening at somepoint, losing its capillary flow), but thats a good thing, really. The other nice feature is that CA appears to crystallize into tone enhancing hardness. If one were to use epoxy (my first choice for general rot / punky stabilizing, not just guitar tops), you can thin it about 10% with alcohol, and it flows great, sinks deep. Than sands to powder, and leaves even color for topcoats.
  9. So, Knightro, did you like the samples? Test photo today. Still need to level / crown setup, etc.

    Pretty fine. Got me interested, as I likely have the most exposure on this forum, and need to be wary, but for occasional use, I wouldnt worry about silicosis, especially when using a respirator or just not inhaling when mixing this stuff "Brief or casual exposure to low levels of crystalline silica dust are said to not produce clinically significant lung disease" from Wikipedia.

    Its hard to overfill epoxy. When I fill the back of my quilted carbon fiber, I mix in glass microspheres (glass bubbles) to displace volume (cutting cost of expensive epoxy) and act as a sanding aid. I add as much as 150 to 200% by volume. Then the epoxy acts like morter around the "bricks". Then add cab-o-sil, of course to thicken it more so it spreads like frosting. You would have to add a lot of pigment to degrade the properties. One trick is to mix in to capacity, then heat it gently, which wets out the pigment. Then it flows better, bonds better, but apply it before it kicks.
  12. Mr_Riddlers build thread

    Pouring epoxy as pour-in-place binding is what I would do too. The real trick to keeping pigments suspended without settling is to mix in Cab-O-sil, as a thickening (Thixotropic) agent. This works great in epoxy, and many epoxy mfr's sell it as the primary thickening agent, although may not reveal the common name, mostly known as cab-o-sil, which is finely ground fumed silica powder. Add enough and the mixture won't even pour. Add just the right amount and your pigment will stay in suspension fine without settling. It does tend to add a tiny amount of opacity, making it slightly white.
  13. Waaayyy cool!! Almost looks like dyed Sapele or another figured wood. That is not quilt figure, though, sorry. Its actually mottle grain, similar to Bee's wing mottle, where its a combination of ribbon stripe (where the grain spirals around the circumference of the tree, then switches direction every rainy season (every 12mm to 30mm, radially) for the tree to grow stronger when piercing the canopy), and flame/curl - but wider waves. Not at all quilt, which is buckling compression wood (or fungus - noone really knows), resulting in quilt billows - no spiral grain, as north american woods aren't as tall, and don't need to pierce any canopy, thus not needing interlocked spiral grain (ribbonstripe).
  14. Holy Crap, if you could eat exotic wood, this thread should get a Michelin star. You gotta send closeup pics of that figured ebony - amazing. Never saw that before. If you ever want a seriously figured carbon fiber fingerboard, I will be introducing solid 4mm figured fingerboards in about two months. The one below is epoxy filled face for the cast-in-place inlays, but my latest panels are solid with figure running the whole way through, regardless how deep the radius is sanded. Fret slots cut great with diamond blades.
