Magnetic Bottle Opener

So I’ve been seeing these really cool DIY magnetic bottle openers floating around on the web and wanted to give it a try myself. The idea is the instead of a catch bucket for the bottle caps. Hidden magnets attach the bottle caps to the wood. Pretty cool huh!?! Well, here’s how I made my beer bottle opener for under $25.

Tools Required



Step 1: Cut Oak to Length and Miter Corners

My piece of oak was 8-1/2″ long and I mitered the corners 1-1/2″ in at 45 degrees.

Step 2: Route the Edges (Optional)

Step 3: Drill Holes for Magnets

I started off using only five 1/2″ diameter by 1/4″ magnets. Then after a test I decided to use all ten. These magnets are fairly strong and will catch most bottle caps (not all).

If I were to do it again I might spend a few buck more to get the 2″ x 1/4″ Neodymium Magnet. I also noticed that the magnets probably needed to be placed slightly closer to the bottle opener to catch the cap immediately.

Mounting Options:

I didn’t use anything. That’s because the magnets in the wood also stick to my refrigerator, and are plenty strong enough to hold the beer bottle opener.

If you need to mount it to something non-magnetic you could always use a Sawtooth Hanger or use a Keyhole Router Bit for a nice flush mount.

    I have been making something along these lines for several months, although it’s just simply a 1x4x9 that I will woodburn a design into, finish, stick a REE magnet in the back of, and put on the bottle opener. I initially planned to mount it on my walls (I have a non-magnetic fridge) by just using longer screws on the bottle opener that can go into the wall stud behind it. I found that it’s also good to use a screw at the bottom to minimize the opener moving around from repeated openings over time.

    • Nice work Will! Thanks for sharing and the tips. I bet you could use both screws for the bottle opener as longer mounting screws and it would be enough to take out the movement.

        I’ll give that a try with the longer mounting screws. One question I had: when I was first making these, I used a few small REE magnets, about the size of the ones in your design. I noticed that they would orient themselves, in what I’m assuming is in line with the field of the other magnets already in place. Any idea if that means they are enhancing the magnetic field this way, or if they are destructively interfering? I wasn’t sure if I should turn them over, against the field, and epoxy them, or leave them in the way they orient.

  • OMG this is amazing!!! Super cool, and totally functional. Definitely making this for my husband for his birthday this year; he’ll love it, and I’ll love not finding bottle caps all over the counters (or floors after the cats find them on the counters and start batting them around!) Pinned!

  • Made these for our wedding groomsman gifts. I used my AutoCad software at work to make a 2d layout for all of the drill holes. Made it really easy to mark hole centers on the pieces. Shared my pics as a Pin (see web page)

    • Thats a great idea Jason. Thanks for sharing!

        The other thing I would recommend is using wooden dowels to glue into the holes and then sanding flat to the surface. I needed something to keep the magnets laying flat. With the 16 holes i used, the magnets created their own magnetic field and wanted to stand on their side to push/pull each other. Ended up having to glue and place on a metal table for the magnets to lay flat in the holes until the glue dried.
        Plus the dowels would give a more finished look.

        • Yea I had the same issue. Good call on the wooden dowels and metal table!

    hey, the second I saw the post I just had to make one off these, had a few snags along the way unfortunately when I magnets came I aciddently let two off them collide thus shattering them. things like that can happen so I ordered some more and boom done. cheers for the tutorial made this a lot easier

    • That’s a bummer about the magnets but it turned out great! Nice work!

    I am having trouble getting a strong enough magnetic field. I bought 1/4″ rare earth magnets and I have 8 or 9 as close the the surface without drill through and I can barely get a cap to stick. Not sure what to try next. Ideas?

    How many of the larger magnets would you recommend using?
