Well, bending wet or dry, that is the question! Since it seems to work in both cases, I guess that it is about the time it take for the softener to deeply penetrate the wood and soften it. Maybe the longer the better???

thank you all. Happy to know the glycerin-based softener recipes. About the fabric softener, is it applied pure or mixed with hot water (in what proportion) ? Also, does these softeners are shellac 'friendly' for french polishing? I am from Canada and ss2 as an import is way too expensive because of...

Hi, I just read that Mr. Gore had used fabric softener to help bend difficult wood in the past. I went throught this forum and found that there not seems to exist a 'standard' recipes/procedure, nor what fabric softener to look for (active ingredients). Would somebody be king enough to share a prove...

Ok. I was not expecting so quick answers to my 'problem' ! You are really of great help and generous of your expertise.
Mario

Thanks, both of you!
Trevor, do I also raise the back cross braces if I raise the main back brace as you recommand?
Mario

Thanks Martin for your suggestion, it make sense. Mario
I am still curious about the relationship between top and back vibrational stiffness frequency (but I understand that they were determined from experiences). Or, the error tolerance on target thickness to still comply to the design requierement.

HI Martin,
With or without scalopping the raised lower cross?

Any solutions for over-sanding live back (I follow the Gore/Gilet design books)? Hi, this is about the design parameters for the vibrational stiffness frequency (VSF) values suggested in table 4.5-2 of the design book of Gore and Gilet. My problem is that I over-sanded my back (sepele wood) for the ...
