    question about a glue joint failure

    my wife told me that 2 of her friends from church have told her that their cutting boards have had glue joint failures. i have examined the one, and 2 of the joints have separated along the short way (end grain, rectangular), yet all of the other joints have held together in spite of use and abuse. i could tell by the dryness of this board, that it had not been oiled since the day i oiled it a little over a year ago, and she had cleaned it with hot water. now we have an edge grain cutting board that my wife has used and abused for years, soaked overnight, scrubbed with brillo pads, etc., and it has held together admirably. the only things i can think of with the other 2 boards, especially with the one i had seen, is that it could be a slightly glue starved joint (i use titebond original with all of them, including the one my wife abuses), lack of an oil coating to keep the end grain protected, and quite possibly a trip or two in the dishwasher. any other ideas out there?

    Titebond I & II are not waterproof glues. Titebond III is.

    All the washing could have loosened the joints. Your wife may just have been luck.

    I tell people that water is the enemy when I give them a board. Hand wash in luke warm water and soap, do not soak, rinse immediately and towel dry immediately...essentially the same instructions for a bowl. I use TBIII also... My boards get two treatments of Watco Butcher Block Oil, which is a very thin product that will actually wick entirely through an inch-and-a-half thick end grain board in a very short time. After it dries the board gets the walnut oil/beeswax paste coating buffed out. The recipient gets a small jar of the mixture with refresh instructions. I have a friend that would disregard the instructions and throw a board in the dishwasher. She has often wondered why she never received one of my boards. I made sure her husband knows the reason... and he agrees.

    I checked the titebond site, and this is the way they test the type 1. Boil specimens for four hours, then bake for twenty hours at 145 degrees, then boil again for four hours, cool with running water, then bend until it breaks. I think it may be starved joints as others are still strong.

    I can't believe you would have put together a glue starved joint. I've got a couple of boards I used Type II that I use all the time , end and edge. No issues whatsoever.

    I'm going to lean towards either soaking in water, or dishwasher usage.

    2 things that do not go in the dishwasher.

    Cutting Boards and Knives.

    Been to too many peoples houses where the knives aren't sharp enough to cut butter and the cutting boards are made of plastic.

    From what I have been able to find, the water temperature can range from 120 to 140 degrees. Enough to swell wood and break a weak join. I'm pretty sure that is what happened, as the entire board did not fall apart.
