Here's the next 2 vlogs in the saga - it's taking me a couple of days from filming to getting them up on the 'tube, so bear with me. If you have any particular process that you'd like me to video and put up as one of the vlogs, please let me know. Cheers for now, Dave F. |

I love the looks of this so far . Have you ever thought of offering to sell precut braces lasered like that for others to build with ? |

Those braces are purdy! |

Yup. Cool braces! |

Very cool. Must be lightest braced top in history... |

I think other luthiers have done this before Chris. How about those CF instruments from Rainsong et al? The new bits are a) using an all spruce triple sandwich with laser-cut honeycomb, and b) my smooth bevel idea. Well, that's as far as I can tell (I can't find anyone else who's done these two things before - anyone know differently?). Cheers for now, Dave F. |

Somehow I forgot to process the video I'd taken of laser-cutting the braces. Here it is, albeit out of order with the vlog, but never mind: I haven't really considered making laser-cut braces for money. I have done a few small laser engraving/cutting jobs for other luthiers in the past (if they asked nicely!). My real job (iPhone RF Hardware Engineer) keeps me pretty busy and adequately compensated already. I want to keep my woodworking/music/lutherie as a hobby for now....no deadlines, no pressure I'll post today's activities tomorrow - gotta get to bed.....work in the morning! Cheers, Dave F. |

Looking good! Question: is it easy/safe/advisable to retrofit a CNC router with a laser cutter head? Seems like an interesting addition to the arsenal... |

Mattia - it's technically possible to add a laser to an existing 3-axis CNC machine, but it's not at all advisable. For starters, unless you have a huge gantry with powerful motors, you will have to mount the laser tube at one end of the table then use mirrors to direct the beam first along the X axis, then the Y axis, then finally down to the work on the Z axis. You would need to send a columated beam of laser light down the mirror system to do this without burning the mirror surfaces and then use a de-columating lens at the work head to turn the laser beam into a focused high power beam once again. Actually, this is pretty much exactly what Epilog et al do in thier lasers. The operative word here is "in".....mounting such a system "ON" an open CNC system will create a laser hazard such that it would never be allowed to be used in an industrial environment with people around. I'm sure you could make such a system and use it in your own home, but I'd still be VERY worried about having a high-power laser beam exposed at all. Steve - wadyamean? I'm a "real" engineer with musical and artistic talents to boot..... Cheers, Dave F. |

Exactly - I thought it was interesting to run into another RF hardware guy here - not that many of us around. Iphone and cyclotron RF systems may not have much in common, still ........ BTW, the box looks real good and I am supremely envious of your ability to knock out such cool jigs and parts with that laser |

Loving the vlogs. I'm in Manteca and may have to drop by for a visit. Steve |

This is all really impressive. I'm happy when I get within .01" with most of the stuff I do. Thicknessing tops, sides, and backs is the only thing I can depend on being that close. I really like the top bevel, I might have to steal that idea. |

Give me a shout on PM and I'll send you the addy/phone etc. Have you, or are you going to join NCAL? (Northern California Association of Luthiers) We're just an informal group that meets at peoples' workshops to have a chin wag, catch up, and listen to someone spout on their favorite topic for a bit (actually, its always VERY interesting!). If you like, I'll give you the nod when the next meeting is announced. Cheers, Dave F. |

Let's call it the "Cambrian Smooth Bevel" (so there aren't any nasty letters or threads about it in years to come!). Let me know if you find an easy way to cut the ledges for the binding/purfling around the smooth bevel area! I'm struggling with that right now.....I may have to break out my chisels (if I can remember where I put them.........just kidding......I know where they are....no....really!! ) Cheers, Dave F. |

Dave, Sheldon Schwartz uses similar although smaller arm rest in his Oracle model: http://www.schwartzguitars.com/oracle.htm Anyway, this is so cool build you do, hats off here! |

In fact, they should be in your shop already. See that "empty" looking bucket over there in the corner? It might be somewhere else, I don't know where you keep your buckets. Anyway, its now chock full of kerfs! Go ahead and dump them into the guitar! |

Hey Dave - just wanted to pipe in and say that I'm really enjoying your build! Quite a different approach and use of tools. Thanks for posting the vids as well! Looking forward to the finished product. |

JLK - Well I'll be......just goes to prove there's nothing new under the sun! I doff my cap to Mr. Schwartz and will henceforth pay him due deference! So, it's to be called the "Schwartz Smooth Bevel" from now on.... Aaron - I'm glad you are finding the build interesting. I'm looking forward to hearing how she sounds at the end also. I have a special treat lined up for y'all for the video demo at the end..... Steve/Tony - you guys are great! I found the bucket of kerfings in my workshop when I got over here tonight, just where Tony said they'd be - excellent! Here's a short video of the kerfings restoration process. As you will see, they did the trick! More later... Cheers for now, Dave F. |

After that last video, you may be my new favorite poster here at OLF! Though if you knew how much those kerfs cost, you wouldn't have been so cavalier about brushing the excess on the floor after you poured them in. . . |
