Is there a prize for the right answer? Okay, I'm guessing I am looking at the current INSIDE of the back--which you initially planned to be the outside. Does the center strip go all the way through? Or will it be a highly decorative feature of the inside of the box? It's a real showy set of wood. I think you need to figure out a way to go ahead and use it. Just think of the stories you can tell about it in the future. Man, you have no idea how many times I've come close to doing this--and not just with guitars. Patrick |

Seems like you guys got it You ARE looking on the INSIDE of the back, which was suppose to be the outside, with a near perfect bookmatch! ![[headinwall]](./images/smilies/headbangwalluf8.gif "Mad") Now I have to check how it will look the other way around, which does not have that nice of a match as compared to this side, but with the center strip in, that gives a little bit of a leeway.And I'm still deffinately using this piece of wood, can't pass it up. The strip is not all the way through, maybe a third of the way. Man I used the template on the top, then without thinking traced it on the back. Didn't check anything, just went straight to the bandsaw. I was posting some pix and realized what I have done!   I hope I can still succesfully use the piece. |

I face this issue each time I cut a harp guitar top and back. Measure twice does not cut it. I check myself over and over before I put metal to wood. I know how u feel. Mike |

Let's see the other side of the back first |

Not exactly the same thing, but that is how I learned how to make a 13 frets-to-the-body guitar. |

Just flip it over. The nice decorative center strip inside the guitar will be a conversation piece. It may even become a Lavrov signature item. |

Except I think the strip will be covered up by a spruce center strip. I kind of doubt the structural integrity if i do without it. |

Well, Maks, I'm going to go against the grain here, but here's what I think: If you're confident about your glued surfaces on that center strip, I bet you could get away with leaving the customary interior cross grain reinforcement strip out of this project. Frankly, I've always wondered about those interior reinforcement strips. Of course, I do them, because that's what we're supposed to do. But we've also got numerous, strong, heavy, cross grain back braces running perpendicular to that joined area. They give HUGE reinforcement to the joint. Sure, cross grain strips will reinforce our mating joints, but they also invite their own cross grain movement failures on either side of the strip (unless humidity is kept at a constant level indefinitely. And if humidity levels are kept constant through an indefinite period, then why do we need those strips? I think they are mostly a redundant feature of traditional construction. I do them, but I have never been convinced they are truly necessary. Okay, I know I just stuck my head into a hornet's nest. By the time I check back in after breakfast tomorrow, I'm pretty sure a lot of people will counsel me on the error in my judgement. That's cool, too. Perhaps someone will fill in the gaps in my thinking and point out what I am missing here. But until then, I'm just saying.............. Patrick |

Patrick, I have never used the cross grain patches. None of my instruments have been around long enough to say they won't have trouble down the line though. I'm not convinced it is necessary with the giant back braces either. In Maks's case though, he would have to decide if the center strip joints are as well prepared as a center seam would be since he will end up with one on each side. . . |

I've seen plenty of Taylors without the spruce strip so it might work. If I route a channel for the new back strip, I'll leave a VERY small amount of the actual coco that's there, and the rest will be the "original" backstrip. I know that the purfling fibers aren't purfectly straight so that seam is not flawless there, but it might very well work out once all braced up. I guess we'll have to wait and see I'll try to re-route today and brace it up, see how it feels |

Been there, done that ![[:Y:]](./images/smilies/smiley20.gif "Thumbs Up") Another one of those "what's the least morale-damaging fix to this situation" problems. You may loose the exact bookmatching, but it'll still be a beautiful back.

If your inlay strip doesn't go right through, you can reposition the strip on the other side to improve your bookmatch. If you left a generous amount of excess around the edges, you should have the wiggle room you need. If it does go all the way through, I might cut it out & re-do the centre joint to get the best match possible. I'm a bit of a symmetry freak, though... If all else fails, a three piece back could work for ya, if you use a narrow wedge. |

I dont see what the big deal is. Just use Adobe PhotoShop to flip the back around.
