Suitable Glue

Hello all, I am hoping someone will be able to offer advice on which glue to use on my basic chopping board project.
i have used Titebond 111 on a board where I have tried to have the end wood as the cutting surface. This has required quite a number of smaller pieces (80x18x30) to be glued together. This is the first time that I have used a hardwood,northern box and damsen. Some of the pieces are separating, which has caused me to think that perhaps the timber is too hard for this particular glue.
Any comments will be appreciated.

When it comes to chopping boards, Titebond 3 is one of the most popular choices.
I suspect there are other factors at play...

I prefer polyurethane glue over PVA for laminating

Thank you for the response Junkie and elanjacobs. I haven’t had a problem with the Titebond before but I haven’t laminated such hard wood either. Perhaps the finecut sawblade I use to size the pieces leaves too polished a surface! Perhaps I have applied too much pressure during clamping!
Its great to receive feedback from experienced woodworkers.
Are you prepared to offer a suitable brand name polyurethane glue elanjacobs.
Thanks again.

We bought all our glues at work from this guy TimbaTech Products - TimbaTech Pty Ltd
The polyurethanes are number by cure time (PU15 = 15 mins, PU60 = 60 mins, etc), you've got about 15-20% of that time to get stuff where you want and clamped. Just note that those times are the minimum cure time, so you can take it out of clamps but don't stress the join; we gave it 3-4 times that just to be sure.

I have made well over 1000 end grain chopping boards all using Tiitebond 111,never had any issues, so as you say it could be the timber some timber will fail no matter what glue is used, are they failing at the glue line or is the timber itself giving way

Over-clamping can definitely be a factor in delamination...

I'd put it into the top 3 causes

- contaminated surface (which includes surface oils)
- over-clamping and/or insufficient glue.
- glue is past the use-by date.

I do not think that "the wood is too hard" is a valid cause, although for very fine grained timbers it may, indeed, be "too polished" to provide a good key. Even so, that'd be way down near the bottom of my list.

Hello China thanks your response, the timber is separating on the glue line in all cases. The timber itself is fine. I don’t blame the glue as I like the product and have used it on a number of occasions but never with this timber type.
Skew ChiDAMN!! I agree some or all of the possible causes you have listed could be the problem.
once again nice to receive help from people who have much more knowledge than I.

Is titebond 3 an advanced pva -a polyurethane or what? gather titebond 1 and 2 are pva,s but so much stuff now continues to use the brand name - ie aquadhere -the poly urethane version still sounds like its kinda the same thing. It isnt -brand - yes however far removed. Yet to be convinced if there is MUCH variance with the polyurethanes - havent done scientific tests -but used brands that cost 60% less than some - from what I've seen all seem kindred. Epoxys Do vary also by price - Question comes to is the top price one worth that Nth degree of theoretical superiotity?
