Gluing Metal Ring Cores

Shane Fox asked 4 months ago

Hi there! I’ve been experimenting making wooden rings with metal cores but have been having some problems with the bond between the metal and the wood.

Since I read that you have one of these types of rings for your wedding ring, I figured you know what you’re doing.

I’ve been using Gorilla Glue Clear and CA super glue- putting Gorilla Glue on the ring and inserting it into the wood blank, then dripping CA glue around the edges in any cracks- but have had problems with water getting under the finish.

I was wondering if you had any tips on how to apply the glue or what glue to use. I’d appreciate any input you have. Thanks for your time!

Thank you for the post. I don’t use CA glue at all for the rings, specifically because they can de-laminate really easily with a temperature change or a flex in the band.

CA is a strong adhesive, but the resulting material is very brittle, so it breaks easily under stress or pressure.

The best way to glue your metal cored to your wooden rings is by using two part epoxy.

Also, score the band and the wood along the surfaces that will meet. You can do this with the corner of a chisel, or even with 80 grit sandpaper.

You want to create a rough surface that will hold epoxy and grip with the other surface.

I have never ever had an epoxied ring come apart, even under really bad conditions. In contrast, I have seen dozens of CA rings come apart.

Happy building.
