This can be a great little project that will add a restaurant feel to your kitchen or workshop (wherever you prefer to have a cold one). The bottle opener will stick to any ferrous metal surface, like steel or iron, even a fridge door! The strong magnets can hold a lot of bottle caps, so you don’t have to worry about having to clean it off often. Materials needed:
- Wood of your choice
- Neodymium Magnets
- Bottle opener
Tools you may need: table saw, router, drill or drill press, chisel, screwdriver, and glue.
Step 1: Choose Your Design
It can be as simple as a bottle opener and one magnet screwed to wood, or you can make a nice piece with hidden magnets. Your design can be any size or shape you want, just keep in mind, the larger you go, the stronger magnets you’ll need.
Step 2: Cut Out Your Design
Whatever design you choose, cut it out, router the edges, etc. Once your final design is cut, you are ready to insert the magnets.
Step 3: Insert the Magnets
This step is another designing process. There is two options that work well. The first option is to chisel out a square in the back of the board for one large block magnet. You can use a 46 x 30 x 10 mm neodymium block. Using this large block, it will effectively hold the opener to the steel surface and catch the bottle caps.
The second option is to use neodymium ring magnets (use four 15 x 5 x 4mm) to hold the opener to the steel surface and two powerful 22 x 10mm neodymium disks to catch the bottle caps. This method is a bit easier to manufacture, since all you need is to drill some holes.
The neodymium rings are simply hammered into the wood using a flat-head nail. The large block magnet or the two discs are both epoxied into place. We used a strong two-part epoxy. Superglue could also work.
Whatever method you chose, leave minimal material between the catching magnet and the bottle caps. This will insure you catch many, many bottle caps! The wood thickness over the magnet should be 1.5mm more or less. You can also use a small strip of grippy tape on the back, which increased the friction enough to prevent any sliding on the slick fridge door.
Step 4: Attach the Bottle Opener
After inserting the magnets, it is now time to attach the bottle openers. All this takes is a drill and a screwdriver. If you want to put any finish on your wood, you should do it before attaching the bottle opener.
Drill a small pilot hole where the bottle opener screws will go. Make sure these holes don’t hit the magnets! Then simply screw the bottle opener on and you are done!
