Thanks!
There's no abalone on this guitar. Except for the head stock logo, it's all black MOP, hence the name, Black Pearl.
One of the things I really like about black MOP is the color of the iridescence is different depending on the lighting angle. In those photos, the inlays have a golden look. At other angles it's got a blue, or green, or red tinge or will even disappear into the ebony if the angle of the lighting is correct. |

Location: Pueblo West, CO | Yep. Purfling, fret board inlay and soon, the rosette are all black MOP, not abalone.
I used black MOP for the purfling on my Parlor and really liked the look of it. So, I decided to expand use of it on this CL. |

Location: When?? | The stealth properties of the inlays is great! Various lighting conditions and directions of sight will probably produce a lot of different views of them in terms of individual reflection. Probably never all of them at the same time. Cool concept. |

As it turns out, I really like the look of the wood behind the rosette. As you say, it's got a sublime look to it. 
Wowee! I love the unfinished rosette. It really brings out the color of the top and accentuates the pattern of the rosette.
The black pearl inlays really shine as the perspective changes, then slide off into stealthiness. What a beauty!

THanks, Al. Yep. That's what I really like about the black MOP. Very different from abalone which is all flash, all the time. |

Me,, too!
I love the look of the bare rosette exposing the wood underneath. Unfortunately, the sound hole location in the top and the rosette location don't match, so there's no way I could use this on this guitar, as much as I like how it looks.
Yeah, that's what I really liked when I finished my parlor. The iridescence is there, but extremely understated and totally controlled by the lighting angle. It's really evident on the fret board, to the point of invisibility. |

Except for the rosette, the basic construction is done.

Location: Yokohama, Japan | Stunning! Just the rosette and the pre-amp to go. That is going to be one impressive guitar with the phantom power capable OP-Pro pre-amp! I'm right in the middle of several non-O re-builds; and your projects always give me incentive to push forward! Thanks for another one of your inspiring threads! Can't wait for the finish! |

That's a bummer. I guess it means you have to build another Ovation to use that rosette.

I would except that's the rosette I'm using for this guitar.
Yeah, I don't think you've seen my parlor, either. |

Location: Pueblo West, CO | It's been a week since my last update, but I've been busy.
The factory uses specialized equipment to assemble the old style CL rosettes. The problem is to securely clamp each of the 16 shell segments so they remain in alignment to each other and to the oak leaf pattern in the rosette casing.
I designed a 3D printed caul to clamp each piece of shell into place. Here is the base. Because of the size limitation of the AnyCubic Photon printer, I had to break the bed into four sections. 
Here are the clamping arms.
Clamping arms assembled and inserted into the base. I'll stretch small rubber bands from the hooks in the base over the notch in the arms to provide the clamping force. At least, that's the idea.
This is the 1/4" birch plywood ring that will hold the four base sections together.
Base sections glued to plywood ring. 
Rosette placed into base.
Paper mock-up of shell sections and clamping arms placed into base.
Next job is to see how it works. I've got a couple of rosettes I pulled off project guitars and some spare shell sections. I'll use these to practice.

Well, it was going pretty cool until I actually tried to start clamping test pieces into one of the practice rosette casings.
It was then that I discovered that I'd made the feet a mirror image of how they're actually supposed to be. The paper template was printed for cutting out the shell pieces, not for clamping. IOW, it was backwards.
Oopsie!
It was easy enough to fix the problem in the models. I just mirrored the pieces and created a new print file.
I'm printing out another set of 16 clamps. I can only print 4 arms and 4 feet at a time (a 'set') and each set takes 4 hours to print.
So, I should be able to practice clamping test pieces tomorrow night.

WOW Dan! Just inspiring work there, backwards and all! What kind of adhesives are you planning on using to secure the shell into the rosette? |

Location: Pueblo West, CO | I finished printing the replacement feet. Here's the general idea of how it should work. 
Since I'm working with epoxy, I thought it might be a good idea to apply a generous coat of parting wax to the base and to the feet. I'll let these parts harden overnight, then glue the two pieces above.

Location: Indiana | Sorry if I missed it... you must have acquired your own printer to turn these parts around so quickly. What 3D design program are you using?
This is pure art.
Carry on. |
