Bending Sides and Lam Sides Together?
I'm going to laminate my next sides and was wondering if anyone has bent both sets together? I've got a Fox style bender and was thinking that I could go
steel side set steel heat blanket steel side set steel Down side could be the shear thickness of the set up and incomplete bend that might occur, up side might be the planned cut away bend could be mitigated by another layer? Dunno. Anyone with experience? Thanks |

If I were going to bend 2 sides together, I would do them side by side. I've done it with binding but I don't build my bending forms wide enough for 2 sides wide.
The way you are proposing would create tighter bends on the inside of the curves and wider bends on the outside. Maybe it wouldn't be enough to make a difference though but why start with inaccuracy? Also the outer side set could be a different temperature than inner as one is modified by the bending form. |

Was hoping someone had tried it and failed/succeeded to share the tale. Not sure what I'll do but the experimenter in me will probably try it someday. Thanks again. |

Laminate sides are usually done cold. The wood is thin enough to be pressed into and clamped on a form that takes the sides shape. Glue them up, clamp them up, let it dry over night and when you take it out of the jig they are good to go.

THANKS,
Interesting, never thought of that and have never seen it done that way at least not on YouTube lol. How would one 'dry bend' for a cutaway? Seems difficult at best. |

Check out how Bogdanovich does it:
https://www.jsbguitars.com/learn-gui...es/laminating/ It would not really be any different to add a cut away side. |

That is some interesting info.

Yeah thanks redir. That was a great site and tips. Changing my ideas about what approach to take or wait and gather more information.
I watched Driftwood Guitars lam his sides and was inspired as well. https://www.youtube.com/watch?v=KoqebMnhELg&t=214s |

Anyway as per usual there are lots of ways to accomplish the same task in luthiery. |

If I can find some scrap I'll try bending both sides at once as it seems most methods aren't dependent on perfectly bent sides to begin with. |

I've been experimenting with this as well. I'm doing two sides, both .065" thick, so .13" final thickness. My stack looks like:
Metal Wood Blanket Wood Metal With wood wrapped in damp craft paper. I have a specific reason for trying to do it, I'm working on some guitars that will have tongue drums in the sides and cutting the drums once the sides are bent is pretty difficult. It works reasonably well, but I wouldn't do it if I didn't have to. It also only works for a non cutaway. I also tried laminating them while still flat with polyurethane glue and bending them before it fully sets, and after it has fully set (some polys can withstand heat to around 300F). Those experiments didn't go as well, it either separates before being fully set or is too stiff and breaks once fully set. |
