magnetic bottle opener sliding down fridge - need ideas

The only thing I can think of is to use a stronger magnet. Some of these more modern magnets are exceptionally strong.

I agree with Bertha…the magnet here is not strong enough…..or you might want to imbed a second magnet to keep the opener from turning and sliding. You can make texture (like fluting the handle) for a “grip” which might create enough friction to slow the sliding. You could imbed a small piece of sand paper or add some sand to glue and make some small inlays to slow it down…..There are alot of ways to do this….just depends on what you want to have the finished project to appear.

sounds like magnets is it

you might take some 60grit paper to the door
make it have the traction lol

Stronger magnets…

I was thinking about stronger magnets, but that doesn’t help much for the two I’ve already made :( I got them at the craft store, and there are 6, 1/2” magnets in each one. While not rare earth strong, they are heft little buggers. Maybe I’ll have to order some of the Lee valley ones, they seem much stronger (and cheap!) but I’ll end up paying more in shipping than the magnets I’d buy! Oh well.

That’s what I’ll do for the future, BUT, for the two current ones, any thoughts? I can’t do something too rough, as it’ll scratch the fridge pretty bad.

Rare earth magnets are far stronger than your ceramic type of the same size.
And what most don’t know is you can quadruple the strength of the RE magnets by simply putting a tiny piece of metal on the other side.
Although it may be too late for your existing bottle openers, for the next ones, bore a countersink hole, glue in a washer (or available cups that they sit in) then the RE magnet and finally your wood cover, you will notice a ten times stronger grip compared to the six that you have now.

You might be able to put down a thin film of rubber cement in the areas where the magnets contact. Ugly? Without a doubt. You could probably bore a single new hole & pop a rare earth in there. Ugly? maybe. Good luck!

So you would put the washer on the side facing away from the fridge?

I’ll have to do some tinkering with the ones I’ve already got. I’m not sure what kind of magnets they actually are. They were small metal disks – but I don’t know what they were made from. Likely not rare earth – it seems companies are very apt to advertise if they were RE. You live and learn….

for the future, definitely stronger magnets will solve your problems, With 6 1/2 in magnets in your current project, it must weigh a half pund, and only have a bout a quarter pund pulling force. with the rare earth, you will get double the force from a single magnet the same size and weight as one of your current ones. as far as saving this project, the only thing I can think of is to it over so those screws catch the top of the fridge door, and the magnet just holds it against the door. you arent going to get much more friction against an enamel or stainless door than you are getting with silicone.

It might be that if you put a large washer-like magnet on the fridge you might be able to get the bottle opener to stick reliably to that.

Or combine those last two ideas: build a hanger bracket for each opener (that the screws will catch and hang onto), and use more powerful magnets to hold those to the fridge.

-- My broker promised me he would treat my money as if it were his own. Trouble is, he did.

For the one’s you’ve already made, you might get two 3/4 dia X 1/4 thick rare earth magnets, stack and stick both to the fridge door and hang the cap screws on the magnets. Bet the opener would stay put then!
For future openers…..stronger magnets and a washer.

”So you would put the washer on the side facing away from the fridge?”

Yes, a bare magnet has waves of flux permeating all around it, a washer (or any ferromagnetic medium) will focus the waves away from it, increasing its strength.
Putting the magnet in a metal cup so the sides are also covered (like what you can find here) will force the waves even tighter giving you the maximum strength of a magnet.
A 1” rare earth magnet in a ferromagnetic cup can easily lift 25 pounds.
