What can I use instead of wooden dowels?
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.
How do I choose a dowel pin size?
Diameter: Ideally, the diameter of the dowel should be approximately 1/3 – and never more than 1/2 – of the thickness of the wood being joined. For example, if your product is 1” thick, you should be considering a dowel pin 3/8” in diameter. If your product is 1-1/4” thick, a 7/16” diameter would be more suitable.
