If I bent.... I mean.... If a friend of mine bent 2 two left sides, could the one be straightened out and then re-bent the other direction? It was taken out of the bending machine after bending but before being "cooked" for too long. It was only in there about 15 minutes. It's EI RW, by the way. It's a dreadnought. My friend is an idiot.

Not that I have ever done this.... But I have used my Wife's iron - I mean an advanced Unbending iron device - to unbend a side. Worked great. Glenn |

I think someone on this forum once showed us a link with a kind of big iron used in hotels, there was enough room to put a side in it and flatten it. |

I'm also wondering how long I should wait to try to rebend it. I know that wood will tend to case-harden after being bent. Just don't know how long it takes to rehydrate again. It's raining here if that makes any difference. Sent from my iPhone using Tapatalk |

I've straightened and re-bent EIR, Walnut and Maple -- not sure I buy the case hardened premise not been a problem for us? But anyway, we mostly discover the error right away -- spritz it and go to work to correct the error. |

I've rebent sides the opposite way before. EIR is about as forgiving as it gets. If you have a bending pipe, "unbend" it on the pipe then put it back in the bending machine. If you don't have a pipe, put it back in the slats and blanket and get it hot and work it along the edge of your bench to straighten it, then put it back in the machine. Don't forget to bend it the correct way the 2nd time around. |

A cheap steam iron is the best tool I have found for unbending. Bob |

Thank you so much for all the replies. I have a steam iron but I think my heating blanket should do the trick. At least for initially straightening it out. If there are any bubbles or faceting still going on, I bet the steam iron would work great. Sent from my iPhone using Tapatalk |

Yes a clothes iron and a damp rag. Just heat the high spots and when the wood starts to relax iron the whole side flat. |

I've found that spritzing SuperSoft II will almost immediately take bends out without any heat applied. DAMHIKT. |

And the clothes iron worked. |

Attachment: ImageUploadedByTapatalk1445996050.120957.jpg Thank you Henry W. Seeley! I managed to get this thing flattened out with an iron. I have it clamped to my bench under a board. I'll try re-bending it (In the correct orientation this time) sometime tomorrow.Thanks again for the tips everyone. Sent from my iPhone using Tapatalk |

Just re-bent that side. Couldn't have gone smoother. Attachment: ImageUploadedByTapatalk1446071579.464280.jpg Attachment: ImageUploadedByTapatalk1446071592.681075.jpg Sent from my iPhone using Tapatalk |

Just looked this back up to see how it turned out (cause I have to re-bend a side too). Aaron can you show us some more pictures of your vise there.....? Looks like some custom mods from a typical pattern makers vise. |

I once bent a side for an OM. Not only was it bent for the wrong side, but I decided to make a cut-away body instead of regular. So I had to unbend the side, and, not only just rebend it the opposite way, but needed to bend in the cut-away shape, too.....and it was Snakewood, one of the more difficult woods to bend. I soaked it in hot water for about a half hour and was then able to get most of the original bend out with a clothes iron, enough to get the heating blanket and slats on. It rebent easily into the opposite side with the cutaway. That's my worst side bending horror story, and it ended happily  Grant |

| Post subject: | Re: Can you un-bend a side? |
It depends on the wood. For oily woods like EIR you could practically bend it backwards and forwards, all without heat. I bent them backwards and forwards a few times to correct a few mistakes. For woods that requires super soft II to even bend into a Dreadnaught shape, not so much... |

Quote: how many people have bent two left sides? I did it once early in my career. There is a simple way to avoid it. When I lay out the pattern to profile the sides, I draw a line on the inside of both sides at the waist. This is foolproof if you lay the sides together opened like a book, and mark both at once. I hand bend using a hot pipe, and the line shows me where to start the bend for the waist, and which direction to bend it (line facing up). Quote: Just don't know how long it takes to rehydrate again. I have rebent many sides to change body shape. I have been known to soak sides in the bathtub for several hours. In my experience, wood that has already been bent once is actually a little easier to bend the second time around. |
