I started the process of making my first rocking chair. The rockers will be shaped using bent lamination. Any suggestions on the glue I should use? I was planning on using TBIII but if there’s a better choice for this I’d like to hear it. The wood will be QSWO.

I just completed my first bentwood lamination project and I just used original titebond. It works great and it dries more completely than TBII or TBIII since it is not waterproof. However, I don’t know that that would be any kind of issue in a situation like this.

I don’t think it’s a question of glue so much as time in the form.

The thicker your laminations, the more it’s going to want to spring back, ergo it stays in the form longer. If the wood’s desire to spring back is very strong, then the form should overbend it to allow for that.

In general, the more your strips are inclined to bend, the easier everything will be.

In the book “Wood Bending Made Simple”, the author recommends Dap Weldood PLastic Resin Glue. If you go to Amazon and look up the book, it will let you thumb through some the pages of the book.(page 29,30). It gives you a little more setup time and dries more rigid which is what author says you want for bent glue ups. White and yellow glues have a little more flexibility than he likes for this purpose.

Plastic resin glue. Dries hard, won’t creep and ruin your finish.

Thanks for the tips and sugestions, all! I think I’ll have to pick up some of that plastic resin glue.

You need a glue that dries hard and doesn’t allow springback. Plastic resin – either DAP or Unibond 800 – meet this requirement. Making your veneers thin enough to bend easily around the form helps. Epoxy also works well but it’s a lot more expensive. Both are messy to work with and can be toxic so wear a respirator while mixing if using DAP, and wear protective gloves to keep it off your skin while applying. I usually go through 3 or 4 pairs of gloves per bent lamination. It’s also a good idea to machine it the next day before it becomes overly hard to avoid damage to cutters. Don’t let these cautions prevent you from using it though. Any of the three will do an excellent job. I’ve done dozens of bent laminations with both plastic resin and epoxy and have never had one come apart. Just follow the manufacturers directions, especially when it comes to proportions.

I agree with Jack.

Using Unibond 800 or any plastic resin glue will prevent spring back, both coming out of the form, and long into the future, since as it is a ridgid glue. It prevents creep, or movement, whereas Titebond glues remain flexible forever.
