What technique are you builders using to do this? Mainly on those guitars that have a valute. Are there any videos of anyone doing this?

Assuming you mean gluing the veneer(s), you can make a caul with a "reverse" volute (that fits into the rear headstock shape well) and then pad it (eg carpet underpad) to clamp the veneer uniformly. There are other methods. |

For a simple upturned volute, I just thickness the back strap, bend the back strap on a hot pipe to match the upturn radius, clean both gluing surfaces, and glue with clamps and a caul shaped to match (I usually put in some wedges under the caul at the radius point to ensure a tight squeeze). There may be a tutorial on this in the tut section. |

That's just about how i was thinking it would be done. But most times my brain won't allow me to believe that the "easiest way" is the "right way". |

Here's one I did with ebony. I bent the ebony to shape and then used a caul padded with cork. A diamond type volute would, I suppose, have to be carved first and then the joint fitted. Attachment: DSCF0623.JPG

I did one recently and used a piece of kerf kore and several clamps in place of a shaped caul. Kerfing a small piece of wood might work nearly as well. Bending ply would be another way to go. |

I Judd did one with a caul cut close and two peices of high density foam sndwiched between. I clamped the dog snot out of it. The foam gets pretty firm once compressed but can still even up the shape of a not perfect caul. What glue are you guys using? I used polyeurethane, figuring I never want it to come apart and it gives plenty of clamping time. It sure made a mess though. |
