crash6882 Posted November 15, 2010 Report Share Posted November 15, 2010 I am working on a guitar which i am using curly maple for the back and sides. the planks which I am using are narrower than i wished but i'm trying to make due. I had pieces cut and glued together as a 3 piece back. once the sides got done the back is too small. I have since then seperated the back pieces to start over. I was wondering what everybody thought of doing a 4 piece back. structurally how would it affect my bracing??? Quote Link to comment Share on other sites More sharing options...
verhoevenc Posted November 15, 2010 Report Share Posted November 15, 2010 It wouldn't at all. 4-piece backs are fairly common enough. Glue lines are stronger than the surrounding wood if done right, so unless you're putting an inlay strip down ALL 3 joints... it won't affect your bracing/structure at all. In case you WERE putting inlay strips down all the seems (hypothetical) the only difference it would make is you should probably put a cross-grain thing like a lot of people put down the center of a two-piece back. That said, those are only really needed if you are putting a center strip... otherwise... it's just a waste of your time and added weight.

crash6882 Posted December 8, 2010 Author Report Share Posted December 8, 2010 My next problem is.............. I'm trying to decide whether to joint the pieces straight or to cut the pieces at angles. I have laid out the boards at the angle and it doesn't seem to look all that much different. If I screw up one board my project comes to a hault, and i only have one more month to finish it. I'm trying to weigh the risk with the difference in looks. If anybody has pictures of a 3 or 4 piece back with boards cut at angles. or any suggestions on which you would do. Quote Link to comment Share on other sites More sharing options...
verhoevenc Posted December 8, 2010 Report Share Posted December 8, 2010 If when the 4 pieces go together you can't tell it's not two pieces... I say go with the 4-piece. If not, and the 3-piece looks better, go with that. I did a 3-piece on a terz. You can see the 2" flairing out to about 3" wedge center (don't remember EXACT measurements, but that's about it) if you look. Chris Quote Link to comment Share on other sites More sharing options...
