Have you seen this "3x5 cards" technique?
Good luck! Sam |

First, however, one needs to decide what geometry one is trying to achieve. Hence my previous questions. Once one knows that, then one can select a method of achieving it.

Wow! Thanks Left of Sam and Charles!
This is exciting! It feels like it's right up my alley regarding budget and achieving correct radii.
A big question that I have which I don't think can really be answered without doing or experimenting is: After gluing up the braces (the X- brace is spruce/rosewood/spruce laminated) to the top, which is glued under tension how much spring back will occur. So if the design calls for a 12' radius on the top and a 10' radius on the bottom...Do I start with a 8-9' radius on the top and hope it springs back to 12'? Same situation for the bottom. I see the problems with following a design where measurements are taken off a finished guitar versus a design that is drawn up as the guitar is built.
