For Stronger Joints, Dowel with All-Thread Rod and Epoxy

For a super-strong joint that doesn't require a lot of precise fitting, try using epoxy and all-thread rod as a substitute for dowels and woodworker's glue. Drill your holes in the same location as you would for a dowel assembly, but make the holes about ¹⁄₁₆ " larger than the diameter of your all-thread rod.

Now, thoroughly coat your all- thread "dowel" and fill each hole about a third of the way to the top with 5-minute epoxy. Assemble the joint so that the excess epoxy fills the gaps between the hole and the all-thread rod, align the pieces, and clamp.

The gap between the all-thread rod and the sides of the hole gives you a margin of error so you can reposition pieces for a better fit. And because epoxy can fill gaps while retaining its structural integrity, the strength of your joint is not compromised.
