I drilled a hole in a wood edge to insert a rare earth magnet. I used a forstner bit so the bottom would be flat I used an epoxy to hold the magnet in the hole, but it didn’t hold. The magnet has a very smooth hard surface. What adhesive do you think would work?

Maybe try construction adhesive, or try scuffing the back of the magnet with sandpaper to give the epoxy something to bite into. Also make sure the magnet is cleaned with acetone or mineral spirits. I’d go with acetone since it dries really fast.

i usually buy magnets with a countersunk hole in the center. Nothing like a #8 wood screw to hold a magnet in place.

I used gorilla glue. Still holding a year later. Just don’t use too much(expansion)

I also am surprised that epoxy did not work. I use super glue.

I’ve used E-6000 for such things, glued metal to glass with it O_o If the superglue doesn’t work give that a try.

I’ve made quite a few refrigerator magnets with left over pieces of exotic wood.

I found a drill bit that was just the right size. The magnet fits into the hole snugly. Using glue is optional, but I always put a drop of thick CA in the bottom of the hole before inserting the magnet. I couldn’t remove one of those magnets if I wanted to (with or without the glue).

FYI – Refrigerator magnets made with exotic wood are very popular, simple gifts.

I recently recessed some 1/2” diameter magnets in sassafras.
I drilled an undersized hole for the magnet.
Then scuffed up the glue side of the magnet with sandpaper.
Put a dab of gel super glue in the hole.
Then pressed the magnet in the hole with an F clamp.
It worked out well.

Hi Ron:

I use Lee Valley’s Rare Earth Magnets. BUT! I don’t glue them inPlace. LV also sells “Cups” for the Magnets. They have a small CountersunkHole in the bottom. You Screw the Cup in Place then simply Drop In The Magnet.

LV Claims the cups also Double the holding Power of the Magnet. Thay also caution you that if you ever want to get the Magnet back out that you should cut a small slice out of the side of them BEFORE Installing both, so you can use a small screwdriver blade to get the Magnet back out.

I’m short on time or I’d go there and post the Link.

I just did anyway. SHE can wait! ...LOL… This is the link to various Sets of Magnets and Cups. there are other Combinations you can get to from there.,42363,42348&ap=1

Hope it helps.

Hi Rick: I didn’t now about the cups and washers. I have the magnets, and I will make the cups and washers. I only need two of each.

MrRon, I use Two Ton Epoxy for a lot of my projects. Works great, about 30 minute working time. I was first told about this by a guy who built golf clubs. I used it for that- takes a lot of punishment! You can get it at the local box store or hardware store. Our local Ace Hardware store has it.

Question for richgreer- how about showing us some of the ref. magnets you make? Specific designs or a nice piece of finished wood with the magnet? Interested.

Have your say...
