Constructing a Magnetic Knife Holder is a popular project using our neodymium magnets. Here we’ve built our own using simple construction methods and include what magnet sizes can work best! The construction really is pretty simple, but the choice of magnets is where it can be more difficult to decide what will work best.
- the wood of your choice
- disc neodymium magnets
- adhesive and screws.
- Table saw
Cut Out Desired Size
Cut out a block of flat timber to size. Ours is 2″ tall and 16″ wide, from 3/4″ thick cherry. In hindsight, 18″ is probably nicer. We have heard from some parents who need to make a fancy design, say the letter K for kitchen. Whatever your layout is, the manner continues to be the same.
Create a Fixture for the Groove
We created a fixture for cutting the groove in a nice, immediately line with a handheld router. At this point, you should decide which face of the wood is nicer, so you can cut the groove on the opposite side. You may additionally have a different manner to do this or other gear that may be used. With the gear we’ve got here, this changed into a quality alternative for us.
This simple fixture is crafted from some MDF board and is sized to our router. We used a desk saw to reduce out the hole in the MDF board, but a Jigsaw or Bandsaw may paintings better (and be safer!)
Cut the Groove
Using the fixture and router, we reduce the groove inside the again of the knife holder. Make sure to set the intensity nicely to depart the favored thickness of wood. We left 1/16″ thickness of ultimate wood.
This is where a few technical facts approximately magnets comes into play, but it’s far simple. The much less material left, the smaller (and cheaper) magnets you can use. The more cloth, the stronger the magnets will need to be to correctly hold the knives. We assume 1/16″ of material left is a superb thickness. This means we set the router intensity to 11/16″.
Route the Other Edges and Sand
After cutting the groove, we desired to have a nice fillet on the other edges, so we used the router for this. Again, your design is probably different, ours is quite simple. We then sanded the groove and piece smooth. At this point, all major cuts at the block are finished, so that you can sand to complete as well.
Insert Disc Neodymium Magnets
his subsequent step is our favorite part, placing the magnets! We placed the block on a steel cookie sheet, to help maintain the magnets in the vicinity at the same time as setting them into the groove. We positioned paper in between to protect our finishing sand. Our groove is 1/2″ extensive and we used 1/2″ x 3/16″ magnets
The orientation of the magnets is important. They have to be positioned in alternating polarities. If you have a look at the magnets, the poles could be North, South, North, South, etc. The edges attract on this orientation, so you will understand if they are being installed right. If you try and place them facet by aspect and the magnets repel, genuinely flip one of the magnets so it attracts.
Note: Neodymium magnets are very hard and brittle. If they’re allowed to slam together, they could probably break. This process must be carried out carefully. The steel cookie sheet clearly helps keep the magnets down in order that they do not slam to each other.
Adhere the Magnets in Place
In this last step, we adhere to the magnets in the vicinity even as still at the steel sheet. While many different sorts of adhesives will work well, we used a silicone adhesive. Make sure to cover all of the magnets along the whole groove. Don’t be afraid to be generous with the adhesive!
After the adhesive dries, you can finish the block with something finish you choose (oil, stain, wax, etc).
Install the Block
Once the adhesive is dry and your block is finished, its time to put in the block! We fastened it to the wall the usage of screws for a quick, clean install.
Make positive you drill a pilot hole earlier than screwing! It could be terrible to get all this manner after which crack the timber with a screw. Once your block is fixed to the wall (or anyplace you place it), area your knives to the block and enjoy!
