I have aset of African Blackwood backs that are 6 1/2 inches wide. Not enought for a full two piece back. I was thinking of putting a wedge of curly Spanish Cedar in the center and using curly Spanish Cedar for the neck. This will be a classical guitar by the way. Can someone tell me how to join the pieces and how to reinforce them. Do you use a center strip type reinforcement for both loints? Please give me some help? Thanks Ken |

I would use a cross grained spruce reinforcement and a wood fiber perfling strip. Spanish cedar is very soft and will dent easy so be careful john hall |

Ken did you try drawing your body outline. Then take the left hand back rotate 90 deg and put on the right hand side.You should have enough material their to get the width you need. Repeat for the other side. You should end up with a pretty well matched 4 pc. back. |

Thanks, That's a great Idea. I think I will have enough to do this. Will make the back look better I am sure. Ken |

I would not join that combo of wood. I don't have any data or proof that it would not work, but I have a hunch that the expanding and contracting properties of the woods would be different enough to possibly cause you some trouble. Just a hunch that's all... |

Ken I hope you understood what I was trying to convey. re-reading my post the rotate 90 deg is wrong. In any event if you have enough width rough cut your outline the join that piece from the upper bout to each lower bout using the right had piece on the left side and left hand piece on the right side. Hope this makes some sense to you. |

This is good, I have been wanting to use different types of wood on the back or I see 14: wide wood sets and it will need at least a 2" spacer wood. Does anyone else see a problem with wedging soft and hard wood together for backs here? Im thinking Mahogany + a rosewood of some type, which is about the same. |

Thanks, It makes perfect sense. I have plenty of wood to do this. It is a great idea and I think will be the best way of handling the situation. The board itself is 6 .625 inches wide so I am just looking to get an inch out of the the trim area. Thanks again for the suggestion. Ken |
