Another bonehead move darn dabbitt It was late and was tired and should have just got out of the shop but my stubbornness and fatigue played some dirty trick to my eyes and i bent one side the other way Dang!

Is it possible to bring this side flat again and rebend the proper way? I'm just worried to stress thi thin wood too much, if anyone had a similar experience, please share your solution, it'd be really appreciated. I use a heat blanket and bulbs, my bender worked flawlessly though!

Thanks for your help

Sergio

Assuming you are using a fox bender with slats/blankets, yes you can bring it back. Just take it all out of the bender, wrap the side and moisten it as you would when you bend, clamp the blankets onto the ends and slowly weight it. You can sort of coax it flat by hand then when it gets pretty close, clamp it all flat to a bench with a bunch of heavy boards on top.
It will go back, not a big deal, worry not.

I've done the same and bent it back. I rewet the side and carefully bent it back againt the form until a fairly flat "s" shape and then bent as usual. I had no problems, but I think things through a bit better now!

You can bend it back but I would use a pipe bender or maybe sandwich the wood like you would normally do for your fox bender and hold the layers together with small metal clamps and slowly relax the wood by hand off the bender. After you get it flat enough just rebend on the bender. I've undone the same problem but I used a hot pipe with a wet towel on top to unbend the mistake and it worked out just fine. My apprentice had to undo the same exact problem a month ago with no ill effects and he was unbending a tight venetian cutaway!

Hey Serge...I am guilty of that bonehead mistake as well. I wet it, weighted it for a few days to get it as straight as possible and then re-bent it. Worked like a charm. Go slowly, as others have mentioned.

Serge I have never done that (that’s my story and I'm sticking to it) But If I had ever made that mistake I would take a slat, then blanket and a slat on a flat bench surface, moisten the wood and rap it, starting at the butt set it on the blanket, clamp the end of the butt down. By hand feel the heat build in the butt and slowly reverse the bend till you get near the waist. Then do the same to the upper bout. This will leave you with only the waist to un-bend. Then with the waist pointing down and in contact with the slat slowly un-bend the waist. This is the only tough part as the waist has been bent more so there is less contact with the flat stats and blanket. Wear good leather gloves and regulate your blanket to maintain about 275 - 300 degs. Once you get it all reasonably un-bent, place the wood still rapped between two slats with the blanket on top. heat to 250-275 and clamp flat and hold for 5 min. this worked for me Oh yea I have never made the mistake before ......I mean it should work for you

I did that just recently, but like someone else recommended, wet the wood down and straightened it back out on the pipe bender. After it was pretty good, not perfect, I wet it down foiled it up and put it back into the SideBender and everything came out OK. I currently use light bulbs and a heat gun, but it would probably work with a blanket, just never done it before.
