I have a table that has some mortise and ten non joints at the aprons. They have gotten weak but they won’t come out. anyone out there has some ideas as to how to strengthen them?. The table is a bit wobbly.

Thanks as always

If the joints are loose, but you can’t pull them apart, they might have nails holding them together. I’ve seen M&T joints nailed from the backside to hold them while the glue dries – or as a repair.

Maybe drill holes for dowels through the joint and drive dowels in with fresh glue to fix the joint?

George’s solution will work. It’s referred to as ‘pegged mortise and tenon’. If that tenon is wide enough, you might try to put TWO pegs in it for added stability.

Thanks all of you for the good ideas. I will give the pegged tenons a try. Now that I think about it should work well for what I want.

I’ve used “Chair Doctor Glue” I got from Lee Valley. It’s about the consistency of Skim Milk and looks like it…LOL…

If there is ANY kind of a space around the Joint,it has a fine point nozzle to help put the glue in. I’ve also driled a few 1/16” to 1/8” Holes from the back, or anywhere you can’t see the holes, and put it in that way. It basically flows in, soaks into the wood (or Wicks) and as it starts to dry it Swells the wood to a nice tight fit.

I had my doubts at first, but I tried it on a couple of Wobbly Chairs. They DON’T Wobble any more!

I also did a couple of tests on my own. 3/4” Pine, drilled 1/16” oversize for a dowel, stuck the dowels in, followed by the glue. 2 days later I tried to twist/pull (pliars) the dowels out. The Pine failed and came out with the Dowel. Glue didn’t give at all.

It’s also an excellent glue for Dovetails and Box Joints that fit TIGHT. It’s also Water Soluble and Sqeeze Out or Overflows can be easily wiped up with Water and a Rag.

EDIT: I got the Link to the Glue at Lee Valley, as below. There’s also a PDF File you can download about the Glue.
