Trying to glue a Metal Dowel to a flat magnet. Super glue is failing me...

There’s not enough contact area between the edges of the dowel and the surface of the magnet for the Superglue to form an effective bond.

Your best bet would be an epoxy with a metal filler, like JB Weld (any hardware store sells it). You would want to use a large enough dab that the end of the dowel is actually immersed in the epoxy. I would even try to work some of the epoxy up into the dowel before attaching it to the magnet to increase the surface area working for you. Then maybe coax some of the epoxy up along the outside of the dowel near the joint for the same reason.

I have had some issues with JB Weld adhering to very smooth metal surfaces, so you might want to scuff the surface of the magnet with sandpaper before bonding.

I should mention that If appearance is important, the JB Weld is a dark gray color, and will be pretty visible. Also, give it a good 24 hours of curing time, preferably in a warm place, before applying any stress.

Try soldering a flat piece of nonmagnetic metal to the aluminum tube then superglue the unit to the magnet, you dont have enough surface area with just the end of the tube

Lee Valley sells steel cups for rare earth magnets like yours. The magnet holds itself in the cup by its own force, and the cup actually increases the hold of the magnet on other surfaces by focusing the lines of force.

The cups have countersunk holes to accommodate a flat head screw. One thing you could do would be to insert a short screw through the hole in the cup, pop in the magnet, then use JB Weld to glue your dowel around the protruding screw.

That would be guaranteed to hold, and would also look quite nice.

aside from JB Weld, which would be my first choice, some may try gorilla glue because it expands and holds pretty good on metal.

@thorninmud Got the stuff today and am trying it out. Already can tell it is better but I’m letting it cure until tomorrow morning before I make a final judgement. However, your second suggestion is awesome, I’m going to buy a few and experiment.

@majorrich I’ll try that if the above fails. Thanks!

Epoxy weld.

Try Gorilla Glue. It really works. Just follow the directions.

I glued brass house numbers to bricks and its still holding.

Gorilla Glue is the best out there.

Shoulda read through the posts instead of skipping to the bottom, @majorrich already said mine.

Hot Melt Glue can work pretty well on both those materials and isn’t brittle like crazy glue.
But the Gorilla Glue sounds good too, esp if you build it up a bit.
