Thanks to all for comments so far. Dale, in case I go for cold hide glue (reversible and very hard, if I got that right), what procedure do you recommend ? Must the wood be warm too ? Should I warm the glue too ? Is the room temperature critical too ? It seems that I can get the Titebond liquid hide glue here. On their site they say no need to warm anything, but the articles of Nick Gravagne recommend to do so. Im a bit concerned with the board warming : I put it in a small room at 35°Celsius and reach 20 % relative humidity. After one day and one night, the board is completely flat, and the dead corner (beyond the dumb bar) begins to show reverse crown. Does this sound normal ? Is there no risk to overdo the board warming ? I initially intended to leave it dry for 3 days, and I can reach 17% relative humidity if I want, but Im a bit afraid to do more wrong than good. Thanks again for taking time for new board newbies. Best regards. Stéphane Collin. -------------- next part -------------- An HTML attachment was scrubbed...
