I have done a few of these and seen them done by other builders. There are no standard measurements. I have always gone with what I thought looked right to me, and what my client wanted. Making some different sized and shaped paper cutouts and positioning them on a finished guitar might help you figure out what you like best. I don't know of any tutorials on how to do these. I simply make sure I glue extra support pieces onto the top and the full width of the side in the cutaway area. That way there will be plenty of gluing surface when the extra side piece is glued in. |

Here's one I did, having borrowed some ideas from Burton LeGeyt: http://www.patfosterguitars.com/opus/index8.html Pat |

Here's a shot of a 'recurve' bevel cut I did a couple of years ago on a pernambuco/red spruce 12-fret 000. The cutaway and binding are beeswing morado. To me the recurve looks alot more finished than the usual scoop cutaway, but it's trickier to make. One thing that helps is to keep the axis of the bends parallel to the center line of the guitar, NOT perpendicular to the side at the place where you're inletting it. The recurve gets really funky if you don't. I bend the wood for the cutaway at a 45 degree angle to the grain. This allows the grain to flow into the binding, so the cutaway becomes an extension of it. I usually use a simple butt joint there. If the binding and cutaway are ebony you can feather the end of the binding into the cutaway, and it will just disappear. I have found no way around cutting the purfling in by hand on the top and side. A sharp knife and patience are your only allies. The trickiest part is the transition at the recurve.

Oh yeah: I bend the binding as usual, with the side line purfling on it. Then I use heat and a knife to separate the purfling from the binding in the upper bout. The binding is cut off to the point where it will butt into the cutaway, leaving the bent purfling hanging out. Now you can bend the purfling in the vertical direction to fit around the lower edge of the cutaway. This avoids the problem of getting a good splice in the while line of the purfling so that it won't show. |
