Hi All: I am trying to repair a broken old kitchen chair. The kids leaned back on back legs and the dowels broke. I have the chair completely apart with all dowel holes cleaned and ready to be redoweled. I am at a loss of what kind of glue to use. I want it ti be very strong but I do not want to use epoxie.
Thank you much Waldo

Thank you all for the same answer.
A few of the dowel are a little loose in the hole. will the tite bond ll take care of that also. Thank you all. Waldo

I dont think the tite bond or any regular woodworking glue is going to "fill" in loose fitting joints, they are a contact glue not filler,{I may be wrong} you may have to resort to the gorrilla glue type, or get creative and plug the hole with appropriate size dowel, and then redrill so the dowel fits in snug,, otherwise you are never going to get a tight chair, and it will break again,good luck,pat

Dowels add mechanical strength to wood joints in three ways.

1) A dowel adds additional gluing surface
2) A dowel puts long grain across the joint
3) A dowel has a very low moisture content and when the glue causes the dowel to expand, the joint becomes very rigid.

If after cleaning out the dowel holes, the replacement dowels fit snugly, go ahead and glue up. If the dowels are loose, I would try to go up to the next larger size dowel.

As for glue type, TB II should work very well. Although I've not tried it, TB III seems to be very liquid after it is applied and may cause the dowel to expand even more. I have seen a TB III end grain to edge grain broken apart after 45 minutes. The end grain part actually pulled wood fibers off of the edge grain. (i.e. The glue appears to be stronger than the wood.)

For a very good fit, hot hide glue would be best. For any gaps or excessive space, a two part epoxy would be the best choice.

Which can fill voids in the loose fitting dowels without redrilling and going up another size. What's your reluctance to using it??

BYW, if the kids insist onleaning back on the chair, use a breakaway system where the entire back separates off the chair and the kids falls over backwards hopefully learning a lesson, don't mess with old men or old chairs. bill

Epoxy is really not difficult to work with. I use it a lot when working on projects on my boat. I also recently used it for the exact same reason that you need it.

It is also used to fasten the golf club heads to the shaft. That is really why I have the 5 minute type around.

Epoxie it is. I will have to get some as all I have on hand is the 5 min. stuff.
Thanks Waldo

The five minute stuff should work just fine.

2 Part epoxy would do the job. I would not use 5 minute epoxy, or any epoxy that mixes at a 1:1 ratio. They are not as strong.
Use an epoxy that mixes at a 2:1 ratio or more.
First wet the surfaces with unthickened epoxy, then thicken the epoxy with a filler and apply more and assemble and clamp the joint.
Check out this, from the West epoxy folks. I used a lot of epoxy in boat repairs and the West stuff is great. other brands work good also.

You do realize that dowels are never the size they are marked, don't you?
