August 13, 201213 yr I know about steam bending but I don't have that set up. I want to bend into a complete circle some maple and was wondering if anyone has experience bending wood by boiling it?
August 13, 201213 yr I'm going to be watching this post Phil. I've never had much luck ar boiling and I'm curious to see what I did wrong. Ron DudelstonSite AdministratorAbove and Beyond WoodWorks
August 13, 201213 yr Dimensions? When I made the last Challenge Coin Holder, I used our largest pot (big round dutch oven) and put a veggie steamer basket in the bottom of the pot. Added enough water to come up to the bottom of the basket. Steamed and then bent the wood- walnut.

August 13, 201213 yr The reason you should not boil is it the water you will introduce is so very much greater than if you had steamed it.You won't make it like before it was kilned ( assuming it was kilned) because that involved inter-cellular water that kilning removes, but you will make it sodden through and through and it'll take a while to dry out.The temperature regime of 100 - 180 Celsius is appropriate for endothermic lignin bond relaxation so boiling water should be right, but the quantum of the water so introduced is just too much. Also the monomers that comprise lignin can take on water swell and that can create problems.Here is some readinghttp://www.iupac.org/publications/pac/pdf/1962/pdf/0501x0233.pdfhttp://www.cellulosechemtechnol.ro/pdf/CCT9%282010%29/P.353-363.pdfhttp://aob.oxfordjournals.org/content/81/6/729.full.pdf
